Exercise: 7 benefits of regular physical activity.

You know exercise is good for you, but do you know how good? From boosting your mood to improving your sex life, find out how exercise can improve your life.

Want to feel better, have more energy and even add years to your life? Just exercise.

The health benefits of regular exercise and physical activity are hard to ignore. Everyone benefits from exercise, no matter their age, sex or physical ability.

Need more convincing to get moving? Check out these seven ways that exercise can lead to a happier, healthier you.

1. Exercise controls weight

Exercise can help prevent excess weight gain or help you keep off lost weight. When you take part in physical activity, you burn calories. The more intense the activity, the more calories you burn.

Regular trips to the gym are great, but don't worry if you can't find a large chunk of time to exercise every day. Any amount of activity is better than none. To gain the benefits of exercise, just get more active throughout your day. For example, take the stairs instead of the elevator or rev up your household chores. Consistency is key.

2. Exercise combats health conditions and diseases

Worried about heart disease? Hoping to prevent high blood pressure? No matter what your current weight is, being active boosts high-density lipoprotein (HDL) cholesterol, the "good" cholesterol, and it decreases unhealthy triglycerides. This one-two punch keeps your blood flowing smoothly, which lowers your risk of heart and blood vessel, called cardiovascular, diseases.

Regular exercise helps prevent or manage many health problems and concerns, including:

Metabolic syndrome.
High blood pressure.
Type 2 diabetes.
Depression.
Many types of cancer.

It also can help improve cognitive function and helps lower the risk of death from all causes.

3. Exercise improves mood

Need an emotional lift? Or need to lower stress after a stressful day? A gym session or brisk walk can help. Physical activity stimulates many brain chemicals that may leave you feeling happier, more relaxed and less anxious.

You also may feel better about your appearance and yourself when you exercise regularly, which can boost your confidence and improve your self-esteem.

4. Exercise boosts energy

Winded by grocery shopping or household chores? Regular physical activity can improve your muscle strength and boost your endurance.

Exercise sends oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.

5. Exercise promotes better sleep

Struggling to snooze? Regular physical activity can help you fall asleep faster, get better sleep and deepen your sleep. Just don't exercise too close to bedtime, or you may be too energized to go to sleep.

6. Exercise puts the spark back into your sex life

Do you feel too tired or too out of shape to enjoy physical intimacy? Regular physical activity can improve energy levels and give you more confidence about your physical appearance, which may boost your sex life.

But there's even more to it than that. Regular physical activity may enhance arousal for women. And men who exercise regularly are less likely to have problems with erectile dysfunction than are men who don't exercise.

7. Exercise can be fun — and social!

Exercise and physical activity can be fun. They give you a chance to unwind, enjoy the outdoors or simply do activities that make you happy. Physical activity also can help you connect with family or friends in a fun social setting.

So take a dance class, hit the hiking trails or join a soccer team. Find a physical activity you enjoy, and just do it. Bored? Try something new, or do something with friends or family.

Exercise to feel better and have fun

Exercise and physical activity are great ways to feel better, boost your health and have fun. For most healthy adults, the U.S. Department of Health and Human Services recommends these exercise guidelines:

Aerobic activity. Get at least 150 minutes of moderate aerobic activity. Or get at least 75 minutes of vigorous aerobic activity a week. You also can get an equal combination of moderate and vigorous activity. Aim to spread out this exercise over a few days or more in a week.

For even more health benefits, the guidelines suggest getting 300 minutes a week or more of moderate aerobic activity. Exercising this much may help with weight loss or keeping off lost weight. But even small amounts of physical activity can be helpful. Being active for short periods of time during the day can add up and have health benefits.

Strength training. Do strength training exercises for all major muscle groups at least two times a week. One set of each exercise is enough for health and fitness benefits. Use a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions.

Moderate aerobic exercise includes activities such as brisk walking, biking, swimming and mowing the lawn.

Vigorous aerobic exercise includes activities such as running, swimming laps, heavy yardwork and aerobic dancing.

You can do strength training by using weight machines or free weights, your own body weight, heavy bags, or resistance bands. You also can use resistance paddles in the water or do activities such as rock climbing.

If you want to lose weight, keep off lost weight or meet specific fitness goals, you may need to exercise more.

Remember to check with a health care professional before starting a new exercise program, especially if you have any concerns about your fitness or haven't exercised for a long time. Also check with a health care professional if you have chronic health problems, such as heart disease, diabetes or arthritis.

Essay about Exercise – Benefits

Is exercise beneficial? How is it good for you? And what is exercise? Essays like the one below will help you discover the answers to these questions.

Introduction

Benefits of Exercise

Works Cited

Do you want to live a good life feeling great with improved mental psyche and energy levels void of some chronic diseases coupled with sound sleep all in one package? Look no further; regular exercising will offer this all-inclusive package of benefits. Many people just know very little about goodness of exercise; regrettably, they do not know how good it can get over time.

The good news is that, exercise delivers results regardless of sex, occupation, physical ability, or age. Exercise results are yours for taking; once you put the input, the output is almost certain.

Unfortunately, people will always find excuses for not exercising and even some will quote myths associated with exercise for them to stay out. Many exercise activities are not strenuous and require very little efforts; for instance, dancing for fun. The truth is; exercise is good because it will help you have good moods, manage chronic diseases, and manage weight giving you good shape.

Goodness of Exercise

Exercise helps in improving one’s mood and mind status. Mood is a state of mind. Physical activity triggers the body to release chemicals known as endorphins. These chemicals enable one to be happy and peaceful. The contemporary society is set in a way that people can work without involving a lot of physical exercise.

Moreover, many people are being forced by circumstances to take jobs that they do not like. Chances that such people will slump into stress, depression, low self-esteem, and insomnia are high.

However, exercising improves all these by improving one’s mood. For instance, during exercise, individuals set goals and by beating the timeline to accomplish these set goals, make one feel good and this improves his or her self-confidence and self-esteem. It is logical that a confident and self-esteemed person will have good moods. Human body is made up of active cells and they need to be kept active; exercise offers these.

As Mayo Clinic Staff posit, “As you exercise, your body gets fitter and stronger, and thus, your mind starts seeing everything, including yourself in a better light” (Para 4). Have you ever heard of people claiming the only thing they do when stressed up is exercise? These few individuals have discovered the secret to let go of in-built pressure. Brain is made up of muscles and exercise is good for brain muscles just as food is good for the body.

Good news to those battling with chronic diseases as hypertension, diabetes and osteoporosis among others; exercise is the way out. Research indicates that regular exercise combats these diseases. According to Hawk, “exercise is the silver bullet for improved health” (Para. 1). In combating heart diseases, exercise strengthens heart muscles, increases High Density Lipoproteins (HDLs), and reduces Low Density Lipoproteins (LDLs). These lipoproteins are cholesterol derivatives and scientists term HDL as ‘good’ cholesterol and LDL as ‘bad’ cholesterol.

Reduction of LDL with subsequent increase of HDL promotes smooth blood flow and replenishes heart functions. In Type II diabetes, the body is insensitive to insulin probably due to weight gain amongst other causes. Exercise helps in shedding weight and this makes the body insulin sensitive. Consequently, this insulin breaks down sugar molecules in the body thus lowering blood sugar levels eventually combating diabetes type II.

Nowadays, poor feeding habits and little or no exercise makes people as young as fifteen to suffer from osteoporosis. However, exercise offers reprieve to this nightmare by strengthening bone tissue formation and maintenance. Finally, research indicates that exercise improves immune system response and this helps to keep minor infections at bay.

Finally, exercise helps in keeping body shape. No one likes obesity or out of shape body. Unfortunately, many people love talking how they hate their over weight bodies without doing anything about it; lip service. Exercise is the way to attaining that elusive figure you have always craved for, over the years.

It is natural that, during physical exercise, the body burns thousands of calories. Body weight results from excess energy, which is converted to fat and stored in different body parts. As one exercises, metabolism rate increases leading to breakdown of fats making your body slimmer and healthy.

Research indicates that, “To lose one pound of fat, you must burn approximately 3500 calories over and above what you already burn doing daily activities” (Buemann & Tremblay 193). These researchers make it clear that normal daily activities are not sufficient to burn the required calories in the body; therefore, exercise is the way out. Fortunately, you do not need to check into a gym to manage weight loss; far from it, 20 to 30 minute walk every day or cycling for fun is enough to keep weight gain under control.

Unfortunately, many people complain that exercise is not good because it is not fun. This is true and it does not apply to exercise alone; it applies to anything that someone does. If you do not enjoy what you are doing, it can never be fun. However, the claims that exercise is not fun are only excuses; not reasons. The fact is, there are many exercise programs, and out of them, every one can find a program that excites him or her. Exercise can be done in a group or individually.

Moreover, most of practices that people do for fun qualify as exercises. For instance, taking a stroll in the neighborhood in the evening is enough to relax one’s mind. Teenagers are fond of cycling for fun; however, even though they do not know it, cycling is a great lot of exercise.

So, what is the way out of these excuses? Identify an exercise that excites you; an exercise that you will do without much hustle. For instance, decide to engage in flexibility training exercises like yoga and sit-ups or even join a dancing group. By doing something that excites you, fun will be inevitable. However, remember to do whatever you are doing on purpose with discipline. Discipline is the key to any successful story you will ever hear.

Exercise is all-inclusive package that will enable you live almost a stress-free life, full of energy with improved self esteem and sound sleep not forgetting how you will be able to combat some diseases like hypertension and diabetes type II. During exercise, the body releases endorphins that restore peace and felicity.

Moreover, nothing equals the thrill that one gets by accomplishing set goals and exercise offers this opportunity to set both short and long-term goals and accomplish them. Again, exercise prompts the body to produce more ‘good’ cholesterol and eliminate the ‘bad’ one thus improving blood flow thus keeping hypertension at bay.

Any good doctor will tell you exercise is as essential as sleep or feeding. Finally, exercise enables you to maintain body shape by shedding those extra pounds. Unfortunately, many people complain that exercise is not fun; however, this is just an excuse, not a reason. There are many exercise programs to choose from, every one can get a program that excites him or her, and as the excitement sets in, fun follows. Anyway, who does not want to live a peaceful and happy life? Not even you, start exercising and start today.

How Exercise Strengthens Your Brain

Physical activity improves cognitive and mental health in all sorts of ways. Here’s why, and how to reap the benefits.

An illustration of a person running; various colored dots surround the top of the runner; a large white brain shape is in the background.

By Dana G. Smith

Growing up in the Netherlands, Henriette van Praag had always been active, playing sports and riding her bike to school every day. Then, in the late-1990s, while working as a staff scientist at the Salk Institute for Biological Studies in San Diego, she discovered that exercise can spur the growth of new brain cells in mature mice. After that, her approach to exercise changed.

“I started to take it more seriously,” said Dr. van Praag, now an associate professor of biomedical science at Florida Atlantic University. Today, that involves doing CrossFit and running five or six miles several days a week.

Whether exercise can cause new neurons to grow in adult humans — a feat previously thought impossible, and a tantalizing prospect to treat neurodegenerative diseases — is still up for debate . But even if it’s not possible, physical activity is excellent for your brain, improving mood and cognition through “a plethora” of cellular changes, Dr. van Praag said.

What are some of the benefits, specifically?

Exercise offers short-term boosts in cognition. Studies show that immediately after a bout of physical activity, people perform better on tests of working memory and other executive functions . This may be in part because movement increases the release of neurotransmitters in the brain, most notably epinephrine and norepinephrine.

“These kinds of molecules are needed for paying attention to information,” said Marc Roig, an associate professor in the School of Physical and Occupational Therapy at McGill University. Attention is essential for working memory and executive functioning, he added.

The neurotransmitters dopamine and serotonin are also released with exercise, which is thought to be a main reason people often feel so good after going for a run or a long bike ride.

The brain benefits really start to emerge, though, when we work out consistently over time. Studies show that people who work out several times a week have higher cognitive test scores, on average, than people who are more sedentary. Other research has found that a person’s cognition tends to improve after participating in a new aerobic exercise program for several months.

Dr. Roig added the caveat that the effects on cognition aren’t huge, and not everyone improves to the same degree. “You cannot acquire a super memory just because you exercised,” he said.

Physical activity also benefits mood . People who work out regularly report having better mental health than people who are sedentary. And exercise programs can be effective at treating people’s depression, leading some psychiatrists and therapists to prescribe physical activity. The Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity per week is a good benchmark.

Perhaps most remarkable, exercise offers protection against neurodegenerative diseases. “Physical activity is one of the health behaviors that’s shown to be the most beneficial for cognitive function and reducing risk of Alzheimer’s and dementia,” said Michelle Voss, an associate professor of psychological and brain sciences at the University of Iowa.

How does exercise do all that?

It starts with the muscles. When we work out, they release molecules that travel through the blood up to the brain. Some, like a hormone called irisin, have “neuroprotective” qualities and have been shown to be linked to the cognitive health benefits of exercise, said Christiane Wrann, an associate professor of medicine at Massachusetts General Hospital and Harvard Medical School who studies irisin . (Dr. Wrann is also a consultant for a pharmaceutical company, Aevum Therapeutics, hoping to harness irisin’s effects into a drug.)

Good blood flow is essential to obtain the benefits of physical activity. And conveniently, exercise improves circulation and stimulates the growth of new blood vessels in the brain. “It’s not just that there’s increased blood flow,” Dr. Voss said. “It’s that there’s a greater chance, then, for signaling molecules that are coming from the muscle to get delivered to the brain.”

Once these signals are in the brain, other chemicals are released locally. The star of the show is a hormone called brain-derived neurotrophic factor, or B.D.N.F., that is essential for neuron health and creating new connections — called synapses — between neurons. “It’s like a fertilizer for brain cells to recover from damage,” Dr. Voss said. “And also for synapses on nerve cells to connect with each other and sustain those connections.”

A greater number of blood vessels and connections between neurons can actually increase the size of different brain areas. This effect is especially noticeable in older adults because it can offset the loss of brain volume that happens with age. The hippocampus, an area important for memory and mood, is particularly affected. “We know that it shrinks with age,” Dr. Roig said. “And we know that if we exercise regularly, we can prevent this decline.”

Exercise’s effect on the hippocampus may be one way it helps protect against Alzheimer’s disease, which is associated with significant changes to that part of the brain. The same goes for depression; the hippocampus is smaller in people who are depressed, and effective treatments for depression , including medications and exercise, increase the size of the region.

What kind of exercise is best for your brain?

The experts emphasized that any exercise is good, and the type of activity doesn’t seem to matter, though most of the research has involved aerobic exercise. But, they added, higher-intensity workouts do appear to confer a bigger benefit for the brain.

Improving your overall cardiovascular fitness level also appears to be key. “It’s dose-dependent,” Dr. Wrann said. “The more you can improve your cardiorespiratory fitness, the better the benefits are.”

Like Dr. van Praag, Dr. Voss has incorporated her research into her life, making a concerted effort to engage in higher intensity exercise. For example, on busy days when she can’t fit in a full workout, she’ll seek out hills to bike up on her commute to work. “Even if it’s a little,” she said, “it’s still better than nothing.”

My Experience

At the age of 16, I was too fat and unable to run for more than 5 minutes. Due to my weight, I was suffering from many types of diseases. Soon after this, my father pushed me to exercise every morning because exercise frees our body and mind from stress. Every morning my father and I started going to the garden to do activities like yoga, morning walk, flexibility, and many more. In school, our physical education teacher also took all children to the ground to exercise and play outdoor games. Later, I noticed that I was recovering slowly from several diseases and lost a lot of weight. I could see the difference in my energy levels and overall performance and realised that we all should exercise every day.

Overwhelming evidence exists that lifelong exercise is associated with a longer health span, delaying the onset of 40 chronic conditions/diseases. What is beginning to be learned is the molecular mechanisms by which exercise sustains and improves quality of life. The current review begins with two short considerations. The first short presentation concerns the effects of endurance exercise training on cardiovascular fitness, and how it relates to improved health outcomes. The second short section contemplates emerging molecular connections from endurance training to mental health. Finally, approximately half of the remaining review concentrates on the relationships between type 2 diabetes, mitochondria, and endurance training. It is now clear that physical training is complex biology, invoking polygenic interactions within cells, tissues/organs, systems, with remarkable cross talk occurring among the former list.

The aim of this introduction is briefly to document facts that health benefits of physical activity predate its readers. In the 5th century BC, the ancient physician Hippocrates stated: “All parts of the body, if used in moderation and exercised in labors to which each is accustomed, become thereby healthy and well developed and age slowly; but if they are unused and left idle, they become liable to disease, defective in growth and age quickly.” However, by the 21st century, the belief in the value of exercise for health has faded so considerably, the lack of exercise now presents a major public health problem ( Fig. 1 ) ( Booth et al. 2012 ). Similarly, the lack of exercise was classified as an actual cause of chronic diseases and death ( Mokdad et al. 2004 ).

Simplistic overview of how physical activity can prevent the development of type 2 diabetes and one of its complications, cardiovascular disease. Physical inactivity is an actual cause of type 2 diabetes, cardiovascular disease, and tens of other chronic conditions ( Table 1 ) via interaction with other factors (e.g., age, diet, gender, and genetics) to increase disease risk factors. This leads to chronic disease, reduced quality of life, and premature death. However, physical activity can prevent and, in some cases, treat disease progression associated with physical inactivity and other genetic and environmental factors.

Published in 1953, Jeremy N. Morris and colleagues conducted the first rigorous epidemiological study investigating physical activity and chronic disease risk, in which coronary heart disease (CHD) rates were increased in physically inactive bus drivers versus active conductors ( Morris et al. 1953 ). Since this pioneering report, a plethora of evidence shows that physical inactivity is associated with the development of 40 chronic diseases ( Table 1 ), including major noncommunicable diseases such as type 2 diabetes (T2D) and CHD, and as premature mortality ( Booth et al. 2012 ).

Worsening of 40 conditions caused by the lack of physical activity with growth, maturation, and aging throughout life span

The breadth of the list implies that a single molecular target will not substitute for appropriate daily physical activity to prevent the loss of all listed items.

In this review, we highlight the far-reaching health benefits of physical activity. However, note that the studies cited here represent only a fraction of the >100,000 studies showing positive associations between the terms “exercise” and “health.” In addition, we discuss how exercise promotes complex integrative responses that lead to multisystem responses to exercise, an underappreciated area of medical research. Finally, we consider how strategies that “mimic” parts of exercise training compare with physical exercise for their potential to combat metabolic disease.

EXERCISE IMPROVES CARDIORESPIRATORY FITNESS

There is arguably no measure more important for health than cardiorespiratory fitness (CRF) (commonly measured by maximal oxygen uptake, VO 2max ) ( Blair et al. 1989 ). For example, Myers et al. (2002 ) showed that each 1 metabolic equivalent (1 MET) increase in exercise-test performance conferred a 12% improvement in survival, stating that “VO 2max is a more powerful predictor of mortality among men than other established risk factors for cardiovascular disease (CVD).” Low CRF is also well established as an independent risk factor of T2D ( Booth et al. 2002 ) and CVD morbidity and mortality ( Kodama et al. 2009 ; Gupta et al. 2011 ). Similarly, Kokkinos et al. (2010) reported that men who transitioned from having low to high CRF decreased their mortality risk by ∼50% over an 8-yr period, whereas men who transitioned from having high to low CRF increased their mortality risk by ∼50%.

Importantly then, from the above paragraph, physical activity and inactivity are major environmental modulators of CRF, increasing and decreasing it, respectively, often through independent pathways. Findings from rats selectively bred for high or low intrinsic aerobic capacity show that rats bred for high capacity, which are also more physically active, have 28%–42% increases in life span compared to low-capacity rats ( Koch et al. 2011 ). Endurance exercise is well recognized to improve CRF and cardiometabolic risk factors. Exercise improves numerous factors speculated to limit VO 2max including, but not restricted to, the capacity to transport oxygen (e.g., cardiac output), oxygen diffusion to working muscles (e.g., capillary density, membrane permeability, muscle myoglobin content), and adenosine triphosphate (ATP) generation (e.g., mitochondrial density, protein concentrations).

Data from the HERITAGE Family Study has provided some of the first knowledge of genes associated with VO 2max plasticity because of endurance-exercise training. Following 6 wk of cycling training at 70% of pretraining VO 2max , Timmons et al. (2010) performed messenger RNA (mRNA) expression microarray profiling to identify molecules potentially predicting VO 2max training responses, and then assessed these molecular predictors to determine whether DNA variants in these genes correlated with VO 2max training responses. This approach identified 29 mRNAs in skeletal muscle and 11 single-nucleotide polymorphisms (SNPs) that predicted ∼50% and ∼23%, respectively, of the variability in VO 2max plasticity following aerobic training ( Timmons et al. 2010 ). Intriguingly, pretraining levels of these mRNAs were greater in subjects that achieved greater increases in VO 2max following aerobic training, and of the 29 mRNAs, >90% were unchanged with aerobic training, suggesting that alternative exercise intervention paradigms or pharmacological strategies may be needed to improve VO 2max in individuals with a low responder profile for the identified predictor genes ( Timmons et al. 2010 ). Keller et al. (2011) found that, in response to endurance training, improvements in VO 2max were associated with effectively up-regulating proangiogenic gene networks and miRNAs influencing the transcription factor–directed networks for runt-related transcription factor 1 (RUNX1), paired box gene 3 (PAC3), and sex-determining region Y box 9 (SOX9). Collectively, these results led the investigators to speculate that improvements in skeletal muscle oxygen sensing and angiogenesis are primary determinates in training responses in VO 2max ( Keller et al. 2011 ).

Clinically important concepts have emerged from the pioneering HERITAGE Family Study. One new clinical concept is that a threshold dose–response relationship influences the percentage of subjects responding with an increase in VO 2max to endurance training volumes (with volume being defined here as the product of intensity × duration), as previously published ( Slentz et al. 2005 , 2007 ). Ross et al. (2015) later extended the aforementioned Slentz et al. studies. After a 24-wk-long endurance training study ( Ross et al. 2015 ), percentages of women and men identified as nonresponders to the training (i.e., defined as not increasing their VO 2peak ) progressively fell inversely to a two stepwise progressive increase in endurance-exercise training volume, as described next. Thirty-nine percent (15 of 39) of training subjects did not increase their VO 2peak in response to the low-amount, low-intensity training; 18% (9 of 51) had no increase in VO 2peak in the group having high-amount, low-intensity training; and 0% (0 of 31) who underwent high-amount, high-intensity training did not increase their VO 2peak . A biological basis for the dose–response relationship in the previous sentence could be made from an analysis of interval training (IT) and IT/continuous-training studies published from 1965 to 2012 ( Bacon et al. 2013 ). A second older concept is being reinvigorated; Bacon et al. (2013) indicate that different endurance-exercise intensities and durations are needed for different systems in the body. They suggest that very short periods of high-intensity endurance-type exercise may be needed to reach a threshold for peripheral metabolic adaptations, but that longer training durations at lower intensities are required to see large changes in maximal cardiac output and VO 2max .

A comparable example exists for resistance training. Maximal resistance loads require a minimum of 2 min/per wk for each muscle group recruited by a specific maneuver to obtain a strength training adaptation [(8 contractions/set × 2 sec/contraction × 3 sets/day) × 2 days/wk) = 96 sec]. As of 2016, one opinion from Sarzynski et al. (2016) for the molecular mechanisms by which endurance exercise drives VO 2max include, but are not limited to, calcium signaling, energy sensing and partitioning, mitochondrial biogenesis, angiogenesis, immune functions, and regulation of autophagy and apoptosis.

Perhaps more importantly, lifelong aerobic exercise training preserves VO 2max into old age. CRF generally increases until early adulthood, then declines the remainder of life in sedentary humans ( Astrand 1956 ). The age-related decline in VO 2max is not trivial, as Schneider (2013) reported a ∼40% decline in healthy males and females spanning from 20 to 70 yr of age. However, cross-sectional data show that with lifelong aerobic exercise training, trained individuals often have the same VO 2max as a sedentary individual four decades younger ( Booth et al. 2012 ). Myers et al. (2002) found that low estimated VO 2max increases mortality 4.5-fold compared to high estimated VO 2max . They concluded, “Exercise capacity is a more powerful predictor of mortality among men than other established risk factors for cardiovascular disease.” Given the strong association between CRF, chronic disease, and mortality, we feel identifying the molecular transducers that cause age-related reductions in CRF may have profound implications for improving health span and delaying the onset of chronic disease. In two of our recent papers, transcriptomics was performed on the triceps muscle ( Toedebusch et al. 2016 ) and on the cardiac left ventricle ( Ruegsegger et al. 2017 ). We were addressing the question of what molecule initiates the beginning of the lifelong decline in aerobic capacity with aging. Aerobic capacity (VO 2max ) involves, at a minimum, the next systems/tissues, as oxygen travels through the mouth, airways, pulmonary membrane, pulmonary circulation, left heart, aorta/arteries/capillaries, and sarcoplasm/myoglobin to mitochondria. We allowed female rats access, or no access, to running wheels from 5 to 27 wk of age. Surprisingly, voluntary running had no effect on the delay in the beginning of the lifetime decrease in VO 2max . Our skeletal muscle transcriptomics elicited no molecular targets, whereas gene networks suggestive of influencing maximal stroke volume were identified in the left ventricle transcriptomics ( Ruegsegger et al. 2017 ).

Publications concerning the effects of exercise on the brain (from 54 to 216 papers listed on PubMed from 2007 to 2016) have increased 400%. In addition, a 2016 study ( Schuch et al. 2016 ) of three previous papers reported that humans with low- and moderate-CRF had 76% and 23%, respectively, increased risk of developing depression compared to high CRF in three publications. With this forming trend, the next section will consider exercise and brain health.

EXERCISE IMPROVES MENTAL HEALTH

Many studies support physical activity as a noninvasive therapy for mental health improvements in cognition ( Beier et al. 2014 ; Bielak et al. 2014 ; Tian et al. 2014 ), depression ( Kratz et al. 2014 ; McKercher et al. 2014 ; Mura et al. 2014 ), anxiety ( Greenwood et al. 2012 ; Nishijima et al. 2013 ; Schoenfeld et al. 2013 ), neurodegenerative diseases (i.e., Alzheimer’s and Parkinson’s disease) ( Bjerring and Arendt-Nielsen 1990 ; Mattson 2014 ), and drug addiction ( Zlebnik et al. 2012 ; Lynch et al. 2013 ; Peterson et al. 2014 ). In 1999, van Praag et al. (1999) showed the survival of newborn cells in the adult mouse dentate gyrus, a hippocampal region important for spatial recognition, is enhanced by voluntary wheel running. Similarly, spatial pattern separation and neurogenesis in the dentate gyrus are strongly correlated in 3-mo-old mice following 10 wk of voluntary wheel running ( Creer et al. 2010 ), and the development of new neurons in the dentate gyrus is coupled with the formation of new blood vessels ( Pereira et al. 2007 ). Many exercise-related improvements in cognitive function have been associated with local and systemic expression of growth factors in the hippocampus, notably, brain-derived neurotrophic factor (BDNF) ( Neeper et al. 1995 ; Cotman and Berchtold 2002 ). BDNF promotes many developmental functions in the brain, including neuronal cell survival, differentiation, migration, dendritic arborization, and synaptic plasticity ( Park and Poo 2013 ). In rat hippocampus, regular exercise promotes a progressive increase in BDNF protein for up to at least 3 mo ( Berchtold et al. 2005 ). In an opposite manner, BDNF mRNA in the hippocampus is rapidly decreased by the cessation of wheel running, suggesting BDNF expression is tightly related to exercise volume ( Widenfalk et al. 1999 ).

Findings by Wrann et al. (2013) highlight one mechanism by which endurance exercise may up-regulate BDNF expression. To summarize, Wrann et al. (2013) noted that exercise increases the activity of the estrogen-related receptor α (ERRα)/peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) complex, in turn increasing levels of the exercise-secreted factor FNDC5 in skeletal muscle and the hippocampus, whose cleavage products provide beneficial effects in the hippocampus by increasing BDNF gene expression. While future research should determine whether the FNDC5 cleavage-product was produced locally in hippocampal neurons or was secreted into the circulation, this finding eloquently displays one mechanism responsible for brain health benefits following exercise. Similarly, work by van Praag and colleagues suggests that exercise or pharmacological activation of AMP-activated protein kinase (AMPK) in skeletal muscle enhances indices of learning and memory, neurogenesis, and gene expression related to mitochondrial function in the hippocampus ( Kobilo et al. 2011 , 2014 ; Guerrieri and van Praag 2015 ).

Insulin-like growth factor 1 (IGF-1), is central to many exercise-induced adaptations in the brain. Like BDNF, physical activity increases circulatory IGF-1 levels and both exercise and infusion of IGF-1 increase BrdU + cell number and survivability in the hippocampus ( Trejo et al. 2001 ). Similarly, the protective effects of exercise on various brain lesions are nullified by anti-IGF-1 antibody ( Carro et al. 2001 ).

In 1979, Greist et al. (1979) provided evidence that running reduced depression symptoms similarly to psychotherapy. However, the precise mechanisms by which exercise prevents and/or treats depression remain largely unknown. Of the proposed mechanisms, increases in the availability of brain neurotransmitters and neurotrophic factors (e.g., BDNF, dopamine, glutamate, norepinephrine, serotonin) are perhaps the best studied. For example, tyrosine hydroxylase (TH) activity, the rate-limiting enzyme in dopamine formation, in the striatum, an area of the brain's reward system, is increased following 7 days of treadmill running in an intensity-dependent manner ( Hattori et al. 1994 ). Voluntary wheel running is also highly rewarding in rats, and voluntary wheel running in rats lowers the motivation to self-administer cocaine, suggesting exercise may be a viable strategy in the fight against drug addiction ( Larson and Carroll 2005 ).

Similar to the above examples, secreted factors from skeletal muscle have been linked to the regulation of depression. Agudelo et al. (2014) showed that exercise training in mice and humans, and overexpression of skeletal muscle PGC-1α1, leads to robust increases in kynurenine amino transferase (KAT) expression in skeletal muscle, an enzyme whose activity protects from stress-induced increases in depression in the brain by converting kynurenine into kynurenic acid. Additionally, overexpression of PGC-1α1 in skeletal muscle left mice resistant to stress, as evaluated by various behavioral assays indicative of depression ( Agudelo et al. 2014 ). Simultaneously, they report gene expression related to synaptic plasticity in the hippocampus, such as BDNF and CamkII, were unaffected by chronic mild stress compared to wild-type mice. Collectively, these findings suggest exercise-induced increases in skeletal muscle PGC-1α1 may be an important regulator of KAT expression in skeletal muscle, which, via modulation in plasma kynurenine levels, may alleviate stress-induced depression and promote hippocampal neuronal plasticity.

TYPE 2 DIABETES, MITOCHONDRIA, AND EXERCISE

T2d predictions show a pandemic.

In a 2001 Diabetes Care article ( Boyle et al. 2001 ), investigators at the U.S. Centers for Disease Control (CDC) predicted 29 million U.S. cases of T2D would be present in 2050. Unfortunately, the 2001 prediction of 29 million was reached in 2012! For 2012, the American Diabetes Association reported that 29 million Americans had diagnosed and undiagnosed T2D, which was 9% of the American population ( Dwyer-Lindgren et al. 2016 ). More rapid increases in T2D are now predicted by the CDC than in the previous estimate. The CDC now predicts a doubling or tripling in T2D in 2050. The tripling would mean that one out of three U.S. adults would have T2D in their lifetime by 2050 ( Boyle et al. 2010 ), which would be >100 million U.S. cases. The International Diabetes Federation (IDF) reports T2D cases worldwide. In 2015, the IDF reported that 344 and 416 million North American (including Caribbean) and worldwide adults, respectively, had T2D. Furthermore, the IDF predicts for 2040 that 413 and 642 million, respectively, will have T2D. In sum, T2D is now pandemic, and the pandemic will increase in numbers without current apparent action within the general public.

Type 2 Diabetes Prevalence Is Based on a Strong Genetic Predisposition

The Framingham study found that T2D risk in offspring was 3.5-fold and sixfold higher for a single and two diabetic parent(s), respectively, as compared to nondiabetic offspring ( Meigs et al. 2000 ). Thus, T2D is gene-based.

Noncoding regions of the human genome contain >90% of the >100 variants associated with both T2D and related traits that were observed in genome-wide association studies ( Scott et al. 2016 ). Another 2016 paper ( Kwak and Park 2016 ) lists at least 75 independent genetic loci that are associated with T2D. Taken together, T2D is a complex genetic disease ( Scott et al. 2016 ).

Type 2 Diabetes Is Modulated by Lifestyle, with Exercise as the More Powerful Lifestyle Factor

Three large-scale epidemiological studies have been performed on prediabetics, each in a different geographical location. The first study, and only study to have separate study arms for diet and exercise, was in China. The pure exercise intervention group had a 46% reduction in the onset of T2D, relative to the nontreated group, after 6 yr of the study ( Pan et al. 1997 ). Diet alone reduced T2D by 31% in the Chinese study. The second study on T2D was the Finnish Diabetes Prevention Study. It found a 58% reduction in T2D in the lifestyle intervention (combined diet and exercise) in its 522 prediabetic subjects after a mean study duration of 3.2 yr ( Tuomilehto et al. 2001 ). The latest of the three studies was in the U.S. Diabetes Prevention Program. The large randomized trial ( n = 3150 prediabetics) was stopped after 2.8 yr, because of harm to the control group. T2D prevalence in the high-risk adults was reduced by 58% with intensive lifestyle (diet and exercise) intervention, whereas the drug arm (metformin) of the study only reduced T2D by 31%, both compared to the noninnervation group ( Knowler et al. 2002 ). Thus, if differences in genetics in the above three differing ethnicities are not a factor, combined exercise and diet remain more effective in T2D prevention than the drug metformin two decades ago.

Exercise Increases Glucose by Signaling Independent of the Insulin Receptor

A single exercise bout increases glucose uptake by skeletal muscle, sidestepping the insulin receptor and thus insulin resistance in T2D patients ( Holloszy and Narahara 1965 ; Goodyear and Kahn 1998 ; Holloszy 2005 ). After insulin binding to its receptor, insulin initiates a downstream signaling cascade of tyrosine autophosphorylation of insulin receptor, insulin receptor substrate 1 (IRS-1) binding and phosphorylation, activation of a PI3K-dependent pathway, including key downstream regulators protein kinase B (Akt) and the Akt substrate of 160 kDa (AS160), ultimately promoting glucose transporter 4 (GLUT4) translocation to the plasma membrane ( Rockl et al. 2008 ; Stanford and Goodyear 2014 ). Despite normal GLUT4 levels, insulin fails to induce GLUT4 translocation in T2D ( Zierath et al. 2000 ). However, exercise activates a downstream insulin-signaling pathway at AS160 and TBC1 domain family member 1 (TBC1D1) ( Deshmukh et al. 2006 ; Maarbjerg et al. 2011 ), facilitating GLUT4 expression translocation to the plasma membrane independent of the insulin receptor. We contend that exercise could be considered as a very powerful tool to primarily attenuate the T2D pandemic.

Complex Biology of T2D Interactions with the Complex Biology of Exercise

An important consideration from the above is that T2D is such a genetically complex disease that a single gene has not been proven to be sufficiently causal to be effective, at this stage in time, to be a successful target for pharmacological treatment. The expectation for a single molecule target has been met for infectious diseases, which are often monogenic diseases. For example, a vaccine against smallpox was highly successful. Edward Jenner in 1796 produced the first successful vaccine. An important fact is that exercise is genetically complex. The literature allows us to speculate that exercise is at least as genetically complex as the approximately 75 genes associated with T2D ( Kwak and Park 2016 ). An example indicating that exercise is complex biology follows. RNA sequencing analysis of all 119 vastus lateralis muscle biopsies found that endurance training for 4 days/wk for 12 wk produced the differential expression of 3404 putative isoforms, belonging to 2624 different genes, many associated with oxidative ATP production in 23 women and men aged 29 yr old ( Lindholm et al. 2016 ). Our notion is that over 2600 genes suggests complex biology.

A “Case-Type” Study of the Molecular Underpinnings of Exercise, Mitochondria, and T2D Interactions

A PubMed search for the terms “diabetes mitochondria exercise molecular” elicited 74 papers. We arbitrarily selected some of the most recent 50 (spanning from mid-2014 into January 2017), with the assumption they would be representative of any other papers that we did not find in our search. Papers fell into our two arbitrary categories of single gene studies versus “omic”-type studies. First, subcategories of studies that develop themes will be arbitrarily presented.

Recent Studies Show Single Gene Manipulation Alters Mitochondrial Level and Running Performance

Numerous reports in the past couple of years observed that single gene manipulations increase mitochondrial gene expression and activity, which was also associated with increased exercise performance/capacity. A few of these are presented below:

Irisin was shown to increase oxidative metabolism in myocytes and increase PGC-1α mRNA and protein ( Vaughan et al. 2014 ), which extends the first observation made earlier in adipose tissue by Spiegelman ( Bostrom et al. 2012 ).
Patients with impaired glucose tolerance underwent low-intensity exercise training. Patients whose mitochondrial markers increased to levels that were measured in a separate cohort of nonexercised healthy individuals recovered normal glucose tolerance ( Osler et al. 2015 ). In opposition, those patients whose mitochondria markers did not improve, remained with impaired glucose tolerance.
In 2003, muscle PGC-1α mRNA was shown to be induced by endurance-exercise training in human skeletal muscle ( Short et al. 2003 ). PGC-1α was shown to have multiple isoforms ( Lin et al. 2002 ). After a 60-min cycling bout, human vastus lateralis biopsies were taken from both sexes in their mid-20s. Additional biopsies were taken 30 min, and at 2, 6, and 24 hr postexercise. At 30 min postexercise, PGC-1α-ex1b mRNA and PGC-1α mRNA increased 468- and 2.4-fold, respectively, whereas PGC-1α-ex1b protein and PGC-1α protein increased 3.1-fold and no change, respectively. Gidlund et al. (2015 ) interprets the above data as implying PGC-1α-ex1b could be responsible for other changes that have previously been recorded before the increase in total PGC-1α postexercise.
Mice with knockout of the kinin B1 receptor gene had higher mitochondrial DNA quantification and of mRNA levels of genes related to mitochondrial biogenesis in soleus and gastrocnemius muscles and had higher exercise times to exhaustion, but did not have higher VO 2max ( Reis et al. 2015 ).
Mice do not normally express cholesteryl ester transfer protein (CETP), which is a lipid transfer protein that shuttles lipids between serum lipoproteins and tissues. Overexpression of CETP in mice after 6 wk on a high-fat diet increased treadmill running duration and distance, mitochondrial oxidation of glutamate/malate, but not palmitoylcarnitine oxidation, and doubled PGC-1α mRNA concentration ( Cappel et al. 2015 ).
The myokine musclin is a peptide secreted from exercising muscle during treadmill running. Removal of musclin release during running results in lowered VO 2max , lower skeletal muscle mitochondrial content and respiratory complex protein expression, and reduced exercise tolerance ( Subbotina et al. 2015 ).
Lactate dehydrogenase B (LDHB), which produces pyruvate from lactate, was overexpressed in mouse skeletal muscle. Increases in markers of skeletal muscle mitochondria were associated with increased running distance in a progressive speed test, and increased peak VO 2 ( Liang et al. 2016 ).
Another example of endurance-type exercise adaptations is the 2016 paper that transcription factor EB (TFEB) regulates metabolic flexibility in skeletal muscle independent of PGC-1α during endurance-type exercise ( Mansueto et al. 2017 ). Lack of metabolic flexibility, termed “metabolic inflexibility,” is important because it is common in T2D. One definition of metabolic inflexibility is its inability to rapidly switch between glucose and fatty acid substrates for ATP production when nutrient availability changes from high blood glucose levels immediately after a meal to decreasing below 100 mg/dl when not eating for hours after a meal. A clinical consequence of T2D-induced metabolic inflexibility is prolonged periods of hyperglycemia, because skeletal muscle is more insulin insensitive in T2D. In contrast, after sufficient endurance exercise, skeletal muscle increases its insulin sensitivity by a second pathway that is independent of proximal postreceptor insulin signaling (see Stephenson et al. 2014 for further discussion).

Studies Showing that Manipulation of One Signaling Molecule Does Not Alter Expression of All Genes with Mitochondrial Functions Found in Skeletal Muscles of Wild-Type Animals to Exercise Training

A 2010 review article ( Lira et al. 2010 ) concludes from gene-deletion studies that p38γ MAPK/PGC-1α signaling controls mitochondrial biogenesis’ adaptation to endurance exercise in skeletal muscle. Two studies do not completely agree with the conclusion in the review article. The Pilegaard laboratory published a 2008 study ( Leick et al. 2008 ) that did not confirm their hypothesis that PGC-1α was required for every metabolic protein adaptive increase after endurance-exercise training by skeletal muscle. They reported that PGC-1α was not required for endurance-training-induced increases in ALAS1, COXI, and cytochrome c expression ( Leick et al. 2008 ). Their interpretation, at that time, was that molecules other than PGC-1α can exert exercise-induced mitochondrial adaptations. A second study published in 2012 rendered a similar verdict. A 12-day program of endurance training led to the middle portion of the gastrocnemius muscle demonstrating a similar 60% increase in mitochondrial density in both wild-type and PGC-1α muscle-specific knockout mice (Myo-PGC-1αKO) ( Rowe et al. 2012 ). The paper concludes that PGC-1α is dispensable for endurance-exercise’s induction of skeletal muscle mitochondrial adaptations.

Exercise signaling targets have actions that are independent of PGC-1α, which is specific to endurance exercise. In 2002, two groups identified PGC-1β, a transcriptional coactivator closely related to PGC-1α ( Kressler et al. 2002 ; Lin et al. 2002 ). Later in 2012, the PGC-1α4 variant of PGC-1α was found to induce skeletal muscle hypertrophy and strength ( Ruas et al. 2012 ). The importance of the finding of a PGC-1α variant is that it partially explains the phenotypic variation for differing types of exercise. Since the 1970s ( Holloszy and Booth 1976 ), it has been appreciated that the biochemical and anatomical observations between endurance and resistance differed. For example, Holloszy and Booth (1976) noted in 1976 that, whereas endurance-type exercise markedly increased skeletal muscle mitochondrial density with very minor increases in muscle fiber diameter, strength-type exercise, in contrast, increased muscle fiber diameter without increases in skeletal muscle mitochondrial density. Taken together, a drug specific for PGC-1α will not likely mimic separate physical training for endurance, strength/resistance, and coordination types of exercise in the same subject. Thus, the common usage of the term exercise capacity is a misnomer because endurance training and resistance training were shown to have different exercise capacity phenotypes very long ago.

In a 2015 Diabetes paper ( Wong et al. 2015 ), Muoio’s laboratory concluded that changes in glucose tolerance and total body fat depended upon how much energy is expended in contracting muscle rather than muscle mitochondrial content or substrate selection. A finding to support the previous sentence was the glucose tolerance tests (GTTs). MCK-PGC-1α mice and their nontransgenic (NT) littermates were not different in GTT, with both being the most glucose intolerant after 10 wk of high-fat feeding. Adding 10 wk of voluntary wheel running to the two high-fat-feed groups during the next 10-wk period (weeks 11–20 of the experiment) lowered the glucose intolerance, and then during weeks 21–30 of the experiment, glucose intolerance was further lowered by adding 25% caloric restriction with the high-fat food and running during the final 10 wk. The percentage weight lost after 30 wk of high-fat feeding was positively related to greater running distances. No single front-runner gene candidate could be identified by principle component analysis. Taken together, the paper suggests “doubts” that pharmacological exercise mimetics that increase muscle oxidative capacity will be effective antiobesity and/or antidiabetic agents. Rather, Muoio and investigators suggest energy expenditure by muscle contraction induces localized shifts in energy balance inside the muscle fiber, which then initiates a broad network of metabolic intermediates regulating nutrient sensing and insulin action. A further discussion of complex biology produced by polygenicity continues next.

POLYGENICITY OF EXERCISE LEADS TO COMPLEX MULTISYSTEM RESPONSES TO IMPROVE HEALTH OUTCOMES

Multiples tissues, organs, and systems are influenced by physical activity, or the lack thereof ( Table 2 ).

Worsening of maximal functioning in selected major organ/tissue/systems that are caused by the lack of physical activity with growth, maturation, and aging

The higher their maximal function is before the end of each item’s maturation, the longer chances are that the quality of life will remain optimal. The breadth of the list implies that a single molecular target will not substitute for appropriate daily physical activity to prevent the loss of all listed items.

To present one extreme, that most will agree, one molecule will not describe the 1000s of molecules adapting to aerobic, resistance, and coordination exercise training. On the opposite extreme, many could likely agree that usage of the various “omics” underlying all adaptations to physical activity will differ (i.e., not be identical in most aspects) among the next list: various cell types within a tissue/organ, tissues/organs, and various intensities of physical activity (i.e., the thresholds among gene responses for health benefits will differ because of the presence of responders and nonresponders, or protein isoform type); during various types cycling (circadian or menstrual); postprandial versus fasting between meals; male and female; child, adult, and the elderly; trained and untrained; aerobic- and resistance-exercise types; and so forth. Others have repetitively written that only ∼59% of the risk reduction for all forms of CVD have been shown to be caused by effects through traditional factors ( Mora et al. 2007 ; Joyner and Green 2009 ). Thus, we pose the next question: what is the identity of all molecules in the yet-to-be-discovered gap between our knowledge of single gene functions and the totality of personalized prescription of physical activity to maximize the period of life free of any chronic disease, termed health span?

While approaches using single-gene manipulations are valuable tools, research must also focus on integrating exercise-responsive molecules into networks that maintain or improve health. This process will reveal complex, multisystem, polygenic networking essential for the advancement of many goals pertaining to exercise physiology, such as tailoring exercise prescriptions and implementing personalized medicine. One example is the developing myokine network with auto-, para-, and endocrine molecules. The first myokine interleukin (IL)-6 began to be described as early as 1994 by the Pedersen laboratory ( Ullum et al. 1994 ), with a history of its development as the first exercise myokine recounted in 2007 ( Pedersen et al. 2007 ). Since their discovery, myokine action within and at a distance from their origins in skeletal muscle have been increasingly studied, as schematically illustrated by Schnyder and Handschin (2015) ( Fig. 2 ).

Similarly, maximal aerobic exercise is accompanied by tremendous stress on many systems, yet whole-body homeostasis is remarkably maintained. For example, world-class endurance athletes can increase whole-body energy production well over 20-fold ( Joyner and Coyle 2008 ), whereas maintaining blood glucose concentrations at resting levels ( Wasserman 2009 ). Intuitively, such effort would require sophisticated interorgan cross talk and polygenic integration of numerous functions.

Exercise Provides Too Many Benefits to “Fit into a Single Pill”

Despite the well-known benefits of exercise, most adults and many children lead relatively sedentary lifestyles and are not active enough to achieve the health benefits of exercise ( Warburton et al. 2006 ; Fried 2016 ). Accelerometry measurements suggest that >90% of U.S. individuals >12 yr of age and ∼50% of children aged 6–11 yr old fail to meet U.S. Federal physical activity guidelines ( Troiano et al. 2008 ). Given this incredibly low compliance, the identification of genetic and/or orally active agents that mimic the effects of endurance exercise might have high appeal for a majority of sedentary individuals. This high appeal has led to recent identification/development of exercise “mimetics.” In 2009, we set criteria for proper usage of the term “exercise mimetic,” based upon its common usage ( Booth and Laye 2009 ). We gave the Oxford English Dictionary’s definition of mimetic, “A synthetic compound that produces the same (or a very similar) effect as another (especially a naturally occurring) compound.” While many exercise “mimetics” activate signaling pathways commonly associated with muscle endurance, these agents have not completely mimicked all effects for all types of exercise. For example, the AMPK activator 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR), when given daily to rats over a 5-wk-period, did not increase maximal oxygen consumption (VO 2peak ) in the sedentary group of rats that were forced to run to VO 2peak on treadmills, as compared to sedentary rats receiving the vehicle ( Toedebusch et al. 2016 ). Thus, in our opinion, the published claim ( Narkar et al. 2008 ) that AICAR is an exercise mimetic is invalidated because it did not increase VO 2peak . While these agents may undoubtedly have specific health benefits, it is currently impractical to assume that all of the benefits of exercise can be replaced by “exercise mimetics.”

CONCLUDING REMARKS

Exercise is a powerful tool in the fight to prevent and treat numerous chronic diseases ( Table 1 ). Given its whole-body, health-promoting nature, the integrative responses to exercise should surely attract a great detail of interest as the notion of “exercise is medicine” continues to its integration into clinical settings.

Essay on Importance Of Balanced Diet And Exercise

Students are often asked to write an essay on Importance Of Balanced Diet And Exercise in their schools and colleges. And if you’re also looking for the same, we have created 100-word, 250-word, and 500-word essays on the topic.

Let’s take a look…

100 Words Essay on Importance Of Balanced Diet And Exercise

What is a balanced diet.

A balanced diet gives your body the right amounts of food and drink to work well. Imagine your body as a machine; it needs good fuel to run smoothly. This means eating different kinds of foods like fruits, vegetables, grains, dairy, and proteins. Eating all these keeps you healthy and helps you grow.

Why Exercise Matters

Exercise is like a superpower for your body and mind. When you move around, play sports, or run, your muscles get stronger, and your heart pumps better. This helps you feel more energetic and sharpens your brain, making learning easier.

Benefits of Combining Both

Mixing a balanced diet with exercise is the best recipe for staying fit. Eating well gives you the energy to exercise, and exercising helps use the food you eat better. This combo keeps you healthy, happy, and ready for any adventure.

250 Words Essay on Importance Of Balanced Diet And Exercise

Why eating right matters.

Eating a balanced diet means getting a mix of many different foods. This is important because our bodies need various nutrients to grow, stay healthy, and work properly. Imagine your body like a machine; it needs the right fuel to run smoothly. Foods like fruits, vegetables, grains, dairy, and proteins are like high-quality fuel. They help us fight sickness and keep our energy up.

The Power of Exercise

Moving our bodies through exercise is just as important as eating well. When we’re active, our hearts get stronger, our muscles grow, and we feel happier. Activities like running, playing sports, or even walking help our bodies use the good food we eat. Think of exercise as a way to spend the energy we get from meals. It’s like playing to burn off energy and stay fit.

Balance is Key

A balanced diet and exercise work together. If we only eat well but sit all day, we miss out on the benefits of a strong body. And if we only exercise without eating good foods, we won’t have the energy to play or think clearly. It’s like having a bike with only one wheel. We need both wheels – food and exercise – to keep moving forward.

Starting Good Habits

Starting to eat well and move more now is a great idea. It’s easier to keep doing these good things as we grow up if we start young. By eating different healthy foods and being active every day, we can have more fun, do better in school, and live a happy life.

500 Words Essay on Importance Of Balanced Diet And Exercise

What is a balanced diet.

A balanced diet includes different kinds of foods in the right amounts. It gives our body the nutrients it needs to work properly. Imagine your body is like a machine, and the nutrients are like the fuel that keeps it running smoothly. Just like a car needs gas, oil, and water, our bodies need a mix of carbohydrates, proteins, fats, vitamins, minerals, and water.

Carbohydrates are like the main fuel. They give us energy to run, play, and do our daily tasks. Proteins are like the workers that build and fix our body, like when you get a cut and your skin heals. Fats keep us warm and protect our organs. Vitamins and minerals are like special tools that help our body do things better, like using the energy from carbohydrates. Water is super important because it’s like the oil that keeps everything moving without friction.

Benefits of Eating Right

When we eat a balanced diet, our body feels good and works best. Think of your body like a superhero. Eating all the right foods is like giving the superhero the best gadgets to save the day. You can fight off sickness easier, you have more energy to play with your friends, and you can think clearer at school.

Not eating right can make you feel tired, get sick more often, and have trouble focusing on homework. It’s like when the superhero doesn’t have their gadgets, they can’t do their job as well.

What is Exercise?

Exercise is any activity that makes your muscles work and requires your body to burn calories. There are many types of physical activity, including running, jumping, swimming, dancing, and even playing tag with your friends. It’s like taking your body out for a joy ride to make sure everything is running smoothly.

Why Exercise is Important

Just like a balanced diet, exercise has many benefits. It makes your heart strong, like a powerful engine, so it can pump blood all around your body more easily. This helps you to not get tired quickly. Exercise also builds strong muscles and bones, so you can climb higher on the monkey bars or run faster in a race.

It’s not just about your body, either. Moving around and playing can make you feel happier and help you sleep better at night. It’s like recharging your body’s batteries fully every night.

Balance Between Diet and Exercise

Having the right balance of food and activity is like having the perfect team. The food gives you the energy and tools you need, and exercise uses that energy to make your body strong and healthy. If you eat too much and don’t move around, your body won’t use all the energy, and you might feel sluggish or gain weight. If you move around a lot but don’t eat enough, you won’t have the energy you need to play and grow.

In conclusion, eating a balanced diet and exercising regularly are both super important for keeping your body healthy and happy. Just like a superhero needs the right gadgets, your body needs the right foods and exercise to be at its best. Remember to eat a variety of foods and to play and move around every day. This way, you’ll grow stronger, smarter, and be ready for any adventure life throws your way!

That’s it! I hope the essay helped you.
