500 words essay on exercise essay.

Exercise is basically any physical activity that we perform on a repetitive basis for relaxing our body and taking away all the mental stress. It is important to do regular exercise. When you do this on a daily basis, you become fit both physically and mentally. Moreover, not exercising daily can make a person susceptible to different diseases. Thus, just like eating food daily, we must also exercise daily. The importance of exercise essay will throw more light on it.

Importance of Exercise

Exercising is most essential for proper health and fitness. Moreover, it is essential for every sphere of life. Especially today’s youth need to exercise more than ever. It is because the junk food they consume every day can hamper their quality of life.

If you are not healthy, you cannot lead a happy life and won’t be able to contribute to the expansion of society. Thus, one needs to exercise to beat all these problems. But, it is not just about the youth but also about every member of the society.

These days, physical activities take places in colleges more than often. The professionals are called to the campus for organizing physical exercises. Thus, it is a great opportunity for everyone who wishes to do it.

Just like exercise is important for college kids, it is also essential for office workers. The desk job requires the person to sit at the desk for long hours without breaks. This gives rise to a very unhealthy lifestyle.

They get a limited amount of exercise as they just sit all day then come back home and sleep. Therefore, it is essential to exercise to adopt a healthy lifestyle that can also prevent any damaging diseases .

Benefits of Exercise

Exercise has a lot of benefits in today’s world. First of all, it helps in maintaining your weight. Moreover, it also helps you reduce weight if you are overweight. It is because you burn calories when you exercise.

Further, it helps in developing your muscles. Thus, the rate of your body will increases which helps to burn calories. Moreover, it also helps in improving the oxygen level and blood flow of the body.

When you exercise daily, your brain cells will release frequently. This helps in producing cells in the hippocampus. Moreover, it is the part of the brain which helps to learn and control memory.

The concentration level in your body will improve which will ultimately lower the danger of disease like Alzheimer’s. In addition, you can also reduce the strain on your heart through exercise. Finally, it controls the blood sugar levels of your body so it helps to prevent or delay diabetes.

Physical inactivity is a modifiable risk factor (similar to dyslipidemia and hypertension) for a variety of chronic diseases, including cancer and cardiovascular disease. Exercise provides a clear health benefit, which serves in the primary and secondary prevention of these disease processes (the most important being a reduction in cardiovascular disease and premature death). The physiologic mechanisms for such a benefit occur at both a cellular and multisystem level. Prolonged periods of occupational or leisure-time sitting have adverse health effects independent of exercise performed before or after. Almost any form of physical activity (PA) is beneficial, whether part of a regular exercise program or as a series of intermittent, incidental, non-purposeful, lifestyle-embedded activity (causing non-exercise activity thermogenesis or NEAT). The health benefits of exercise appear to be dose-dependent. Physicians should recommend near daily exercise which includes at various times strength training, stretching, and aerobic activity in addition to emphasizing adjustments that allow for reduced sitting and increased activity during daily routines. Patients should understand that for optimal health, exercise is no longer optional.

Introduction

Physical inactivity is a modifiable risk factor for cardiovascular disease, obesity, depression, cancer, diabetes mellitus, hypertension, and osteoporosis. Physical exercise reduces the risk of premature death and prolongs longevity, and is an important treatment modality in the primary and secondary prevention of the above disorders [ 1 ]. For most states in this country, less than half of the population meets CDC exercise recommendations [ 2 •]. The decline in physical activity (PA) occurs both at work and in leisure time, and may have at least partially contributed to the increase in obesity over the past 30 years. Low recreational physical activities have been associated with a threefold increase for major weight gain in men and a fourfold increase in women [ 3 ]. Surveys of PA across the lifecycle show that physical exercise peaks in the middle high-school age range and begins declining through high school and into adult life. A vicious cycle of decline occurs between inactivity and loss of skeletal muscle mass which accelerates with age. With avoidance of activity requiring effort, there is increased loss of exercise capacity. This loss causes the perception of effort associated with even sub-maximal work to worsen, as the anaerobic threshold decreases. The vicious cycle contributes to further inactivity and deterioration of physical function. The only treatment that can break the cycle is exercise.

Impact of Exercise on Aging

Exercise provides powerful health benefits for quality of life, physical function, and independent living throughout the life cycle. Exercise impedes the aging process and promotes longevity. Observational studies have shown that even in the presence of disease processes such as hypertension (HTN), chronic obstructive pulmonary disease (COPD), diabetes, smoking, high body mass index (BMI), and hypercholesterolemia, increasing PA has a dose-dependent effect in decreasing relative risk of death [ 4 ]. In a study of subjects over a 13-year time period, both baseline fitness, and improvement in physical fitness through exercise and PA was associated with significant increases in longevity [ 4 ]. Functional independence with advanced age relates to the overall level of physical fitness. Physical fitness is most affected by the status of the cardiorespiratory and vascular systems, as well as muscle function [ 5 •].

Garatachea et al. provide an excellent review of the effect of exercise on the physiologic changes associated with aging [ 5 •]. Exercise exerts its positive influence on both a cellular level and at the level of organ systems. At the cellular level, exercise helps reduce genomic instability, epigenetic alteration, loss of proteostasis, dysregulated nutrient sensing, cellular senescence, and altered intracellular communication that leads to inflammation. These effects alter the way the body performs transcellular signaling in the skeletal muscle, the turning on and off of genes through epigenetics, and the manner in which the system manages reactive oxygen species [ 5 •]. On a multisystem level, the benefits of exercise include improvement in brain, cardiovascular, lung, and muscle function, favorable alterations in body composition, and advantageous changes in metabolic responses. The report concludes by suggesting that in the future, pharmaceuticals should be designed which mimic the effects of exercise on the aging process [ 5 •].

Effect of Exercise on Treatment of Disease

Robert Butler from the National Institute on Aging has said that “If exercise could be put in a bottle, it would be the strongest medicine money could buy” [ 6 ]. Exercise helps prevent common chronic diseases (primary prevention), and often plays an important role in the treatment of these disease processes (secondary prevention). Specific benefits from exercise have been seen with cardiovascular disease, stroke, diabetes mellitus, depression, cancer, obesity, and osteoporosis [ 7 , 8 ]

Cardiovascular Disease

Increased levels of PA and physical fitness have a graded effect in reducing the risk of death from cardiovascular disease. The relative risk from all cause and cardiovascular disease mortality is reduced 20–35 % by exercise and PA [ 9 ]. In an observational study, subjects in the lowest quintile of exercise had a relative risk of 3.4 in men and 4.7 in women for death compared to those in the highest quintile [ 10 ]. An increase in activity-related energy expenditure by as little as 1000 kcal or 1 metabolic equivalent (MET)-hour of exercise per week has a mortality benefit of 20 % [ 11 ]. Physically inactive women have a 52 % increase in death, a cardiovascular disease-related death that is doubled, and a cancer-related death rate that is increased by 29 % [ 11 ]. These risks on mortality from inactivity are similar to other modifiable risk factors such as HTN, hypercholesterolemia, and obesity. In randomized controlled trials (RCT)s, exercise and PA are valuable for the secondary prevention of cardiovascular disease. Whereas in the past, traditional recommendations for patients with a heart attack included rest and physical inactivity. Newer information demonstrates that exercise actually attenuates or reverses risk of cardiovascular disease [ 12 ]. The benefit of exercise is seen in cardiac rehabilitation, where increasing PA reduces the risk of premature death following a myocardial infarction [ 12 ]. Added energy expenditure of 1600 kcal/week from exercise may halt the progression of heart disease and energy expenditure of >2200 kcal/week can lead to plaque reduction [ 13 ]. The minimum training recommendation for patients following myocardial infarction is to reach 45 % of their heart rate reserve through cardiac rehabilitation [ 12 , 13 ].

Multiple mechanisms have been identified whereby exercise reduces the risk of premature death [ 4 ]. Exercise affects body composition by decreasing abdominal adiposity and improving weight control. Exercise enhances lipid profiles by reducing serum triglyceride levels, raising HDL, and reducing the LDL/HDL ratio. In addition, a recent meta-analysis showed beneficial changes in lipoprotein subclasses associated with regular exercise including a reduction in small LDL-p and an increase in large LDL-p [ 14 ]. Exercise enhances hemodynamics by decreasing blood pressure, increasing cardiac function, and improving coronary blood flow. Autonomic tone is enhanced and shear stress-mediated endothelial function is improved. Exercise reduces systemic inflammation, as evidenced by reduced C-reactive protein (CRP) levels. Improved psychological well-being in response to exercise is associated with reduced stress, anxiety, and depression [ 4 ].

PA is inversely correlated with risk of incident stroke as shown in a large nurses’ health study [ 15 ]. Habitual exercise reduces risk of stroke by 40–50 % at the highest level of PA. Change in PA is protective against stroke as evidenced by the fact that an increase of 3.5 h of exercise or PA per week is associated with a 29 % reduction in ischemic stroke [ 15 ].

Diabetes Mellitus

Exercise is valuable in both the primary and secondary prevention of diabetes mellitus. Aerobic and resistant-type exercise reduces the likelihood of developing type-2 diabetes mellitus. For each 500 kcal of energy expended per week, there is an associated 6 % reduction in the likelihood of type-2 diabetes (which may be even greater with increasing BMI) [ 16 ]. In patients already diagnosed to have diabetes mellitus, walking 2 h per week is associated with a 39–54 % reduction in all-cause mortality from diabetes mellitus, and a 34–53 % reduction in mortality related to cardiovascular disease [ 17 ]. The benefit of exercise on glycemic control appears to be greater with resistance training than aerobic exercise. A meta-analysis of exercise and PA in diabetes showed that exercise reduces hemoglobin A1C by 0.66 %, an effect similar to intensive glucose-lowering pharmacologic therapy [ 18 ]. The mechanisms by which exercise benefits diabetes relate to the fact that exercise increases glycogen synthetase and hexokinase activity [ 4 ]. Exercise reduces GLUT-4 protein and messenger RNA expression and increases muscle capillary density, which helps improve glucose delivery to the muscle [ 4 ].

Increasing PA, either occupational or at leisure, has been shown to exert a primary preventative effect on two cancers—breast and colon cancer [ 19 ]. Moderate exercise of as little as 4–5 METs (equivalent to mowing the lawn or brisk walking), is required to achieve this effect [ 20 ]. Exercise is associated with a 20–30 % reduction in the incidence of breast cancer in women, and a 30–40 % reduction in the incidence of colon cancer in both men and women [ 20 ]. In those patients already diagnosed to have one of these cancers, exercise reduces the likelihood for cancer recurrence and reduces risk from cancer death by as much as 26–40 % [ 21 ]. PA improves quality of life and overall health status in cancer patients. The mechanisms by which exercise improves risk from cancer may relate to reduced fat stores, an increase in energy expenditure offsetting a high-fat diet, activity-related changes in sex hormone levels, improvement in immune function, and reduced generation of free oxygen radicals [ 4 ].

Osteoporosis

Exercise has a valuable effect in the primary prevention of osteoporosis. Routine PA minimizes age-related bone loss. Weight-bearing exercise (especially resistance exercise) increases bone density compared to low impact non-weight-bearing exercise. Exercise prevents 1 % of bone loss per year, an effect which is greater in post-menopausal than pre-menopausal women [ 22 ]. In RCTs, exercise reduces the risk and number of falls, as well as the risk of fracture [ 22 ]. Even in men, PA reduces the risk of fracture by 62 % over the age of 21 years [ 23 ]. Exercise is also valuable in the secondary prevention of osteoporosis. RCTs in the past have shown that exercise with resistance training increases bone density in older osteoporotic women by as much as 1.4 %, while agility training alone increases bone density by 0.5 % [ 24 ]. Stretching, which was used as sham control, was shown to have no effect on the expected decrease in bone density with age [ 24 ]. In a 12-year follow up of over 60,000 post-menopausal women, risk of hip fracture was lowered 6 % for each increase of three MET-hours per week of activity (the equivalent of walking three miles in 1 h) [ 25 ]. Active women with at least 24 met-hours of exercise per week had a 55 % lower risk of hip fracture than sedentary women with no other exercise. Walking at least 4 h per week was associated with a 41 % lower risk of hip fracture than walking less than one hour per week [ 25 ].

Exercise has a valuable therapeutic effect on the treatment on multiple types of depression, including dysthymic, seasonal, bipolar, post-natal, pre-menstrual, atypical, and major depression [ 26 ]. The value in treating depression comes from an innate anti-depressive effect from exercise. Combining exercise with psychotropic medications achieves better treatment results than the same medications alone [ 26 ]. Exercise is relatively inexpensive, safe, and has minimal side effects when done correctly. Exercise may help reduce the dose of anti-depressive medications required. Subjects are less likely to relapse with an active exercise program [ 26 ].

The patients with depression who are most likely to benefit from exercise include those with age <20 or >40 years, higher education, higher baseline physical status, females, untrained subjects, and those with mild to moderate depression [ 26 ]. There are a number of aspects of exercise that get the optimal results in treating depression including programs that are structured, individually tailored to the patient, low to moderate intensity, when it is used as an adjunct to medication therapy, and exercise that is a combination of aerobic or resistive training performed 3–4 times per week [ 26 ]. The mechanism of effect from exercise on depression occurs on a systemic level as well as a direct effect on central nervous system (CNS) function. Exercise appears to increase serotonin, ACTH, endorphins, and endocannabinoids within the CNS. On a systemic level, exercise increases norepinephrine and reduces cortisol, tumor necrosis factor (TNF), and interleukin-6 [ 26 ].

In a controversial article that appeared in Time magazine in 2009, the journalist John Cloud wrote about “The Myth of Exercise” and its effect on treating obesity [ 27 ]. The article suggested that exercise was not good for weight management in obesity. The author pointed out that exercise leads to increased appetite and intake of food and causes a decrease in non-exercise energy expenditure, and therefore that exercise was a poor strategy for weight loss [ 27 ]. A number of letters to the editor of Time magazine followed the publication of this article, including letters from the American Society for Sports Medicine, arguing that facts were misrepresented and that the article gave the wrong message about the health benefits of exercise.

A recent review by Swift clarified the role of exercise in managing or preventing obesity, and suggested that Cloud’s article was in fact an accurate portrayal of the facts [ 28 ]. The key issue of Swift’s review is that exercise without caloric restriction is unlikely to succeed in weight loss [ 28 ]. Increasing PA can prevent weight gain, but it requires 150–250 min per week of moderate to vigorous exercise or 1200–2000 kcal/week expended through exercise to accomplish this feat [ 29 ]. Aerobic exercise by itself is minimally helpful in promoting weight loss, successful in loss of only 0–2 kg total [ 29 ]. Extreme high-volume aerobic exercise can achieve significant weight loss, but this is usually unsustainable by most obese patients. Moderate intensity, surprisingly, is no different than vigorous intensity in achieving weight loss, unless subjects are matched for exercise duration. Resistance training by itself has no impact on weight loss, and aerobic training combined with resistant training has no greater effect than aerobic training alone. However, adding caloric restriction to aerobic training does result in successful weight loss of 9–13 kg, and higher intensity of exercise has the potential for even greater weight loss [ 29 ]. Some obese subjects do experience weight compensation in response to exercise, defined by the circumstances where less weight is lost than expected with the amount of exercise sustained, often a factor related to an increase in caloric intake [ 28 , 30 ]. This is more likely to occur in women performing 150 % of weekly recommendations (compared to women performing only 100 % or 50 % of weekly recommendations) [ 28 , 30 ]. Even if minimal or no weight loss occurs in response to exercise, obese subjects still benefit from the increase in PA due to increased cardiorespiratory fitness, glucose control, endothelial function, improvements in hyperlipidemia, quality of life, and a reduction in future weight gain [ 28 ].

Caloric restriction is better than exercise for significant weight loss initially, and the weight loss is not necessarily enhanced significantly by adding exercise [ 28 ], although exercise training plus caloric restriction does improve body composition by increasing fat loss and decreasing loss of lean body mass [ 31 ]. The greatest value of exercise in the management of obesity occurs not in the initial weight loss, but in the situation where obese patients have lost weight successfully and now require substantial PA to maintain that weight loss [ 28 ]. Interestingly, an “energy gap” has been identified as the difference in energy expenditure before and after weight loss [ 32 ]. The energy gap is estimated to be approximately 8 kcal per day per pound of weight lost. An energy gap, for example, of 40 lbs lost would be associated with 320 kcal of energy. Sustaining this weight loss successfully would require either a continued reduction in energy consumption by 320 kcal per day, or increasing activity-associated energy expenditure by the same amount [ 32 ]. Based on the Set Point theory, both biological and environmental pressures oppose the strategy of food restriction in keeping weight off, but the same effect does not occur with increased PA [ 32 ]. Therefore, while food restriction is the key to weight loss, PA is the key to successful maintenance of the weight lost [ 32 ]. The ACSM has identified that people who successfully maintain weight loss average at least 250 min of PA per week [ 29 ].

Low Back Pain

A 2016 systematic review and meta-analysis reviewed 23 randomized controlled trials evaluating the prevention of low back pain [ 33 ]. Over 30,000 patients were involved in these studies. Ultimately, the combination of exercise (varying regimens of abdominal strengthening, core stability, cardiovascular, and isometrics) plus education regarding prevention of low back pain was found to reduce the risk of low back pain as well as sick leave related to low back pain. Exercise alone was also found to have an impact but had a more short term effect (<12 months), thought to be due to cessation of exercise following the intervention. Other interventions, including back belts, insoles, and education alone were not found to have any impact [ 33 ].

Not All Exercise is Created Equal

Physical activity versus physical fitness.

The lay public tends to use the terms PA and physical fitness interchangeably, but subtle differences between the two exist. Physical fitness is a physiologic state of being with regard to daily living and/or sports performance [ 4 ]. Physical fitness is comprised of cardiovascular, musculoskeletal, body composition, and metabolic components [ 4 ]. Physical fitness is similar to PA, but is more predictive of health outcomes. For example, a high-fit versus a low-fit person is estimated to have a 50 % lower mortality [ 34 ]. Physical fitness, therefore, becomes a better measure of PA than self-reporting. From a public health standpoint, however, it is better and more productive to encourage the public to be physically active and not push the need to be physically fit. Eventually, increased activity should lead to physical fitness.

In the past, guidelines for optimal health seemed to have had a singular focus on aerobic fitness. But a new paradigm shift has occurred with the addition of the concept of musculoskeletal fitness [ 4 ]. In other words, health status can improve due to increased PA in the absence of changes in aerobic fitness. Regular PA can decrease risk factors from chronic disease and disability without changing cardiac output or oxidative potential, especially in the elderly [ 4 ]. The shift has been to focus on the health benefits of musculoskeletal fitness, which may be a critical factor in the functional threshold for dependence with the aging population. Loss of muscular fitness can result in loss of capacity for daily living, and a cycle of decline can ensue [ 4 ]. Improvement in musculoskeletal function can delay the onset of disability, dependence, and chronic disease [ 35 ]. Musculoskeletal fitness is associated with fewer functional limitations and a reduced incidence of cardiovascular disease, diabetes, degenerative joint disease, and coronary artery disease [ 35 ]. Therefore, resistance training that works all the major muscle groups (including legs, hips, back, abdomen, chest, shoulders, and arms) and flexibility exercise, which are necessary to achieve musculoskeletal fitness, are recommended to be done at least twice weekly, to complement aerobic fitness and optimize overall health status.

Adverse Health Risk from Sitting

In an effort to delineate those factors which contribute to the obesity epidemic, researchers are increasingly focused on the adverse health risk from prolonged sitting [ 36 •]. A newly recognized occupational hazard has evolved because of workers needing to sit at a computer screen throughout the workday. Each mean hour of sitting after a total mean of 7 h per day is associated with a 5 % increase in premature death [ 36 •]. More time sitting at work has been shown to correlate with more sitting in leisure time. Prolonged sitting while watching TV at home, for example, has adverse effects on mental health, well-being, and muscle strength. Long sedentary hours have been linked to a twofold increase in diabetes, a twofold increase in cardiovascular disease, a 13 % increase in the incidence of cancer, and a 17 % increase in mortality related to cancer [ 36 •]. It is estimated that the average worker in the USA and England spends 60–70 % of waking hours in a sedentary sitting position. The effect of sitting has been likened to the transmission of a car. Sitting for such a prolonged period is like putting a car in reverse, causing one’s overall health status to go in the wrong direction [ 36 •]. Approximately 20–30 % of the time is spent in light intensity activity, described as postural changes, standing and movement, or ambulation. For less than 5–10 % of waking hours, individuals spend in moderate to vigorous PA. The adverse effect of sitting on health status is independent of the exercise or PA done before or after [ 36 •]. In other words, no amount of PA later can overcome the negative health effects of prolonged sitting.

Changes in the workplace environment may be the key issue to minimizing the negative effects of prolonged sitting. Particularly, in the UK, recommendations and guidelines have been developed to avoid this health hazard [ 36 •]. Workers are encouraged to accumulate up to 2 h per day at work standing or performing light walking, with the goal to progress ultimately to 4 h per day. Workers should interrupt seat-based work with standing-based work. However, workers should avoid both prolonged periods of standing as well as prolonged periods of sitting. Adaptation of these guidelines may lead to musculoskeletal complaints and fatigue, which should be monitored by managers in the workplace. Such health promotion strategies should eventually extend from the workplace to the leisure time [ 36 •].

Non-Exercise Activity Thermogenesis

Non-exercise activity thermogenesis (NEAT) has been described as unstructured PA, energy expended unrelated to sleeping, eating, or sports exercise. NEAT is energy expended outside of purposeful exercise [ 37 ]. Surprisingly, this incidental, non-purposeful lifestyle-embedded PA can have tremendous health benefits. Three components of NEAT include body posture, ambulation, and all other movements (the most important of which may be fidgeting) [ 38 ]. Researchers involved in the study of obesity are finding that in some cases what delineates the lean subject from an obese one is a difference in NEAT, not exercise-associated activity thermogenesis [ 38 ]. Early experiments which helped identify NEAT came from studies where energy requirements were measured and all subjects were placed on a diet of 1000 cal over requirements [ 39 ]. Subjects were then videotaped, and in a blinded fashion designated as fidgeters or non-fidgeters. At the end of the trial, those patients who were designated as fidgeters failed to gain weight, while those identified to be non-fidgeters sustained significant weight gain. The increase in kilocalories of energy expenditure attributed to NEAT was inversely proportional to fat gain in pounds [ 39 ]. NEAT ranges from 15 % of total energy expenditure (TEE) in sedentary subjects to as much as 50 % of TEE in fidgeting physically active people [ 39 ]. Fidgeting has been shown in twin studies to be genetic, with an estimated >62 % heritability [ 40 ]. Simply standing or lightly ambulating can increase energy expenditure by an average of 350 kcal/day (range 269–477 kcal/day) [ 37 ]. NEAT tends to be greater in men than women, in obese subjects rather than lean, and in those with more education than those with less [ 38 , 39 ]. NEAT tends to be seasonal and overall, declines with age [ 39 ]. The concept of an energy gap is pertinent to NEAT. An average citizen in the USA has been shown to gain 1–2 lbs each year through their adult life. An energy gap of 100 kcal additional energy consumed each day would account for this weight gain [ 41 ]. NEAT can be an important contributor to TEE, such that increases in NEAT of as little as 100–150 kcal of activity per day could prevent such weight gain (by offsetting the energy gap) in the vast majority of people [ 41 ]. Recommendations now suggest that if you were not lucky enough to inherit fidgeting, you should “act like a fidgeter,” standing often, getting up from sitting, pacing, parking at the back of a parking lot, and taking stairs instead of elevators [ 40 ].

Continuous Versus Interval Exercise

Long bouts of continuous exercise as a strategy for weight loss or weight maintenance can be a contentious and challenging recommendation for the general public. Longer duration, continuous exercise may be difficult and not particularly enjoyable for patients and may not fit as well with work or home schedules. Research now has shown that interval exercise, which involves alternating short bouts of high-intensity exercise with lower-intensity exercise that allows for partial recovery, can match the health benefits of continuous exercise [ 42 ]. Studies in patients with class-1 obesity (BMI 30–34.9 kg/m 2 ), walking at a moderate level of intensity, randomized to two 15-min intervals of walking versus one 30-min interval, showed essentially the same improvements in overall health status [ 42 ]. Both intermittent and continuous exercise resulted in improvement of maximum oxygen consumption, body composition, and lipid profiles. In some categories, interval exercise even exceeded the benefit seen with continuous exercise (such as VLDL levels and percent fat lost) [ 42 ]. The value of these findings for intermittent exercise stems from three factors: there is less attrition with recommendations for interval exercise, time constraints, and short periods of interval exercising may allow for greater intensity of PA [ 42 ]. An additional study involving 28 sedentary overweight or obese men compared five 45- to 60-min sessions of continuous moderate intensity cycling per week for 6 weeks with three 20-min sessions of high-intensity interval exercise per week (for a total of 60 min) for 6 weeks. Similar improvements in cardio-metabolic risk factors including improved insulin sensitivity, cardiovascular fitness, and a reduction in blood lipids and body fat percentage were observed in the groups [ 43 ]. While cardiovascular fitness was improved to a greater extent in the continuous exercise group, this study, along with numerous other studies of interval exercise showing similar outcomes in different populations, are encouraging in that they show many of the same improvements in overall health with a substantially reduced time commitment [ 43 ]. This is especially relevant as lack of time is cited as the most common reason for not exercising by many. In addition, interval exercise can be easily adapted to an individual’s starting fitness level by adjusting either the duration or intensity (or both) of the high-intensity component of exercise. This may be especially beneficial for sedentary overweight or obese individuals who are new to exercise. In light of both the potential health and time saving benefits, interval exercise training appears to be an appealing and worthwhile exercise option in addition to, or instead of, continuous exercise. The good news for public health is that short walks on a subject’s lunch break or brief periods of activity before and after work all count, and the sum of their duration may have similar benefits to a single continuous interval of exercise of the same duration.

Success of Pedometers

The use of pedometers to increase PA was generated years ago in Japanese walking clubs. The rationalization for the pedometer was that the average stride was estimated to be 2.5 ft. Therefore, 2000 steps should approximately equal a mile, 10,000 equaling about 5 miles [ 44 ]. Based on this rationalization, PA can be classified as sedentary (<5000 steps per day), low active (5000 to 7500 steps), somewhat active (7500 to 10,000 steps), and active (>10,000 steps per day). Highly active physical exercise is associated with >12,500 steps per day [ 44 ]. This is an arbitrary categorization, however, and 10,000 steps per day may be too little for children or too much for the elderly. Weight loss using a pedometer without caloric restriction is associated with minimal to modest weight loss of <2 kg [ 44 ]. Health benefits associated with use of the pedometer may be limited to a reduction in blood pressure, with not much change in cholesterol, triglycerides, or fasting glucose [ 44 ].

Exercise in the Intensive Care Unit

Exercise is becoming increasingly important in one of the least expected circumstances, that of a critically ill patient in the intensive care unit (ICU). Researchers have found that exercising muscle increases the uptake of amino acid fuel and promotes greater protein synthesis [ 45 , 46 ]. Patients in the ICU on a ventilator in some centers are gotten out of bed and encouraged to walk with assistance in the hallway. Other centers have used a pedaling device, some of which can even be adapted for passive activity in a patient who is otherwise sedated and minimally responsive. Exercise in the critical care setting helps maintain muscular strength, reduces the risk for long-term neuromuscular weakness, shortens rehabilitation, and is more likely to result in the patient being discharged to their home [ 45 , 46 ].

Recommendations for Public Health

Similar to the Food Guide Pyramid designed by the USDA, an activity pyramid has been created to guide the public in strategies to increase flexibility, muscular strength, and aerobic capacity ( www.wellspan.org/media/3648/activitypyramid-2009.pdf ). Every day, subjects are encouraged to increase activity in leisure and at work. Three to five times per week, aerobic activity should occur, accumulating 150 min each week ( www.wellspan.org/media/3648/activitypyramid-2009.pdf ). Two to three times per week, muscular activity focusing on flexibility and strength training should be scheduled. Sitting more than 30 min at a time, watching TV, or staring at a computer screen should be minimized or reduced as much as possible ( www.wellspan.org/media/3648/activitypyramid-2009.pdf ).

Guidelines differentiate between moderate and vigorous intensity of PA. Moderate intensity is defined by a 3–5 MET level of effort, and includes activities that cause some increase in breathing and heart rate (such as walking 3–4 miles per hour, bicycling on level ground, light swimming, gardening, or mowing a lawn) [ 4 ]. Vigorous intensity is defined by ≥6 METs, and is exemplified by activities causing large increases in breathing, heart rate, and sweating. Such activities of vigorous intensity would include jogging or running at faster than a 10 min mile, aerobic dancing, competitive sports, heavy yard or construction work, brisk swimming, or fast bicycling [ 4 ].

The amount of PA needed to optimize health is not clear. The particular dose of exercise required to achieve benefits with regard to a particular disease process is difficult to ascertain. For cardiovascular disease, the intensity of PA is inversely and linearly associated with increased mortality, with the biggest effect seen as a reduction of premature death [ 47 ]. PA of >2000 kcal per week extends life by 1–2 years by age 80 [ 47 ]. An average energy expenditure of 1000 kcal per week is associated with a 20–30 % decrease in all-cause mortality. Beginning at a minimum of 1000 kcal per week, increasing benefits are seen with increasing energy expenditure, suggesting a dose-response gradient to the effect of exercise on cardiovascular health [ 47 ]. For diabetes mellitus, there is decreased risk from this disease process with PA of >5.5 METs for at least 40 min per week [ 48 ]. Walking 2 h per week decreases the risk of premature death from diabetes [ 48 ]. Moderate exercise defined by a >4.5 METs for 30–60 min per day reduces both the risk of colon cancer and breast cancer [ 19 ]. For women in particular, >7 h per week of moderate exercise has been shown to be successful in reducing risk of breast cancer (TI01). For osteoporosis, the dose-response gradient is less clear, with recommendations simply emphasizing that osteogenic adaptation is load-dependent and site-specific [ 4 ]. The Center for Disease Control (CDC), the American College of Sports Medicine, and the Healthy People 2010 recommendations provide guidelines for aerobic activity for public health purposes [ 49 ]. Adults should engage in PA of moderate intensity for at least 150 min per week or engage in PA of vigorous intensity for at least 75 min per week. Bouts of exercise may be broken up into smaller increments lasting at least 10 min [ 49 ].

Should Anyone Not be Exercising?

Jim Fixx was a celebrity journalist who helped contribute to the running craze seen in the 1980s in the USA. His sudden death from cardiovascular disease, while jogging, raised questions as to the need for medical evaluation prior to engaging in a program of increasing PA. Moderately strenuous PA may trigger ischemic events, particularly among sedentary people. There is an increased incidence of primary heart attack in high-intensity exercise. In competitive athletes, 80 % of deaths are caused by coronary artery disease. Some subjects do need to have their health risks assessed prior to engaging in an aggressive program.

The degree to which a person is evaluated prior to exercise depends on the presence or absence of cardiovascular disease risk factors and whether the exercise will be moderate or vigorous in intensity [ 50 ]. Subjects at low risk would be those who are young in age (<45 years for male, <55 years for female), are asymptomatic, and have ≤1 cardiovascular risk disease factors. These patients do not need a medical evaluation or stress test for moderate or even vigorous exercise. Subjects at moderate risk are older (men >45 years, women >55 years), or have ≥2 risk factors for cardiovascular disease. For moderate exercise, no medical evaluation may be needed, but these subjects should undergo a stress test. If exercise of vigorous intensity is planned, both a medical evaluation and a stress test should be performed. For those patients at high risk, however, defined by ≥1 sign or symptom of cardiovascular, pulmonary, or metabolic disease, both a full medical evaluation and stress test should be performed before any program is undertaken [ 50 ].

Specifically, those subjects who should not be exercising are those experiencing an acute myocardial infarction, subjects with unstable angina, systolic blood pressure >180, diastolic pressure >110 ml/Hg, uncontrolled diabetes mellitus, poorly controlled congestive heart failure, or thrombophlebitis [ 50 ].

While formal studies have shown that physician counseling is time-intensive and only minimally effective in changing behavior, physicians should no longer avoid the subject of recommendations for exercise as part of the healthcare they deliver to their patients. Physicians can begin by suggesting lifestyle changes such as climbing stairs at work, parking further away from the door on errands, walking regularly, and doing chores at home and in the yard. Clinicians should write on a prescription pad for the patient, specifying the type of exercise, duration, frequency, and intensity. The physician upon discharge from an office visit should determine plans for support and follow up to encourage success, manage obstacles, and prevent relapses. Clinicians should encourage their outpatients to involve community services such as physical therapy, mall-walking programs, school tracks, safe neighborhoods, the YMCA, and walk-a-thon’s.

Physicians should counsel that exercise is not an option. The exercise does not have to be continuous to be effective, and any physical activity counts. Patients should sit less, stand more, and plan their exercise activity at the beginning of each week. Subjects should be encouraged to find activities which they enjoy and involve others to maintain compliance. As Edward Stanley, the Earl of Derby in 1873 said, “Those who think they have not time for bodily exercise will sooner or later have to find time for illness” [ 51 ].

The Top Vibration Plate Benefits for the Elderly

Medically reviewed by:   Dr. Ronald Mochizuki, MD

When it comes to healthy aging, perhaps nothing is more important than maintaining mobility and strength. After all, this is what allows seniors to stay active and engaged with the world.

While traditional exercise requires your body to contend with gravity, vibration plates use micro-vibrations to redevelop muscles and restore joint motion, providing a low-impact alternative. As these waves course through your body, they awaken dormant muscle fibers, helping to restore strength and balance.

In this article, we’ll explore the top vibration plate benefits for elderly users and offer some tips on how to integrate a vibration plate into your fitness routine. 

Understanding Vibration Plates

Before exploring how vibration plates can enhance your life, it's important to understand how they work. Let's delve into the benefits of vibration plates and how they provide an upgrade over traditional exercise.

What are Vibration Plates?

Vibration plates are platforms that:

• Are large enough to stand on
• Plug into a wall outlet
• Reflexively activate muscles using vibration

This continuous resonance penetrates deep muscle fibers, causing them to contract and relax rapidly, often dozens of times per second. Many users compare the sensation to that of a massage chair.

Vibration plates come in all shapes and sizes, from heavy-duty versions you might find in a gym to travel-size models, like the Personal Power Plate . 

You can perform a wide variety of movements on a vibration plate. Essentially, any exercise you can do on the ground can be done on a vibration plate.

How Do They Work?

By subjecting your muscles to constant and precise vibration—50 vibrations per second is sufficient to experience benefits—vibration plates stimulate your muscles and enhance the impact of any movements you perform on the plate. You can even reap benefits simply by standing still.

Precise and consistent vibrations can:

• Trigger your reflex responses
• Activate muscle fibers
• Increase circulation

In fact, studies show that a vibration plate workout may engage up to 97% of your muscle fibers. Traditional exercise, by comparison, usually activates only about 40%.

During vibration plate workouts, tiny tears can form in your muscle fibers. Afterward, your body repairs these fibers, with more extensive healing occurring as more fibers are affected. As they recover, the muscle fibers often become stronger than before. Over time, this enhanced healing helps redevelop and strengthen weakened muscles.  

Key Benefits of Vibration Plates for the Elderly

As we age, our bones naturally become more brittle, and our muscle mass decreases. As a result, seniors may be at a higher risk for falls, fractures, and exercise-related injuries. 

To avoid the risk of injury, many older adults may begin to avoid physical exertion altogether, which can further decrease their fitness level and overall health. Vibration plates offer a solution by providing an effective low-impact and low intensity way to engage muscles and improve strength and balance. This helps counteract age-related issues, enhancing functional fitness and promoting overall well-being.

Here, we’ll cover six major ways vibration can improve the lives of elderly individuals. 

#1 Improved Balance and Stability

What’s the best way to reduce the risk of falls? Improve balance. 

A 2006 study followed a group of seniors engaged in a 47-week whole-body vibration program and compared their balance to a control group that performed standard cardiovascular, balance, and strength training exercises. 

Seniors who received vibration training:

• Demonstrated improved balance overall
• Suffered fewer falls on a moving platform meant to test balance
• Exhibited improvement in handling sudden, toes-down rotation 

Accordingly, the study concluded that long-term use of whole-body vibration systems can help restore balance and posture control.

#2 Increased Muscle Strength

Research also indicates that whole body vibration training can effectively build and sustain muscle mass in older men.

The study monitored a group of men over 60 who participated in regular whole body vibration workouts over the course of a year. 

The final results found that participants gained:

• 9.8% more isometric muscle strength
• 10.9% more explosive muscle strength
• 3.4% more muscle mass

These gains were right on par with those of a control group who performed standard exercises, leading the researchers to conclude that whole body vibration was just as effective as traditional exercise for augmenting muscle strength and mass.

#3 Enhanced Circulation

The circulatory system becomes sluggish over time, and poor circulation often leads to fatigue, low stamina, and vascular issues.

Vibration plates help combat this slowdown. Research has shown that vibration training provides a major boost in oxygen uptake and utilization (an important measure of vascular health) in 60 to 80 years olds. The increases were similar to those experienced by a control group who participated in a traditional cardio program.

This indicates that vibration training can be an excellent tool to boost activation of the circulatory system.

#4 Pain Relief and Joint Health

When it comes to growing older, joint pain is a fact of life. Repetitive impact gradually wears away the cartilage between the bones, and ligaments can become stiff and less flexible.

For many types of joint pain, conventional management strategies involve:

• Weight management

Unfortunately, for many seniors, these remedies can have little effect.

Vibration exercise, on the other hand, has been shown to:

• Reduce pain
• Improve joint function
• Increase extension in affected joints

Accordingly, vibration training may be an excellent way to help restore joint function, mobility and quality of life. 

#5 Improved Bone Density

Bone density isn’t something that’s usually at the forefront of people’s minds, but it plays a powerful role in our health. Unfortunately, aging undermines bone strength and can make the bones prone to breakage. For seniors, fragile bones can significantly increase one’s risk of a fall-related injury.

Research does show that whole body vibration training may slow bone loss, and  increase hip bone density by up to 1.5% after 24 weeks.  

#6 Improved Flexibility and Mobility

In many ways, to live is to move. Strong mobility allows seniors to:

• Live independently
• Remain engaged with the world
• Perform age-appropriate exercise

Older adults have vast stores of wisdom to offer younger generations, and everyone benefits when they remain involved. Whole body vibration can contribute to marked improvements in muscle, joint, and bone health, and these gains work together synergistically to help older adults stay mobile, flexible, and connected longer.

By improving flexibility and mobility, vibration plates support a more active and fulfilling lifestyle. This not only boosts overall physical health but also fosters mental well-being and social engagement, enriching life in meaningful ways.

Practical Tips for Seniors Using Vibration Plates

Whether you're new to vibration training or a caregiver seeking to enhance an older adult's quality of life, you might be curious about how to use a vibration plate. Thankfully, these devices are easy to understand and straightforward to operate.

Getting Started

Once you’ve chosen a quality home vibration plate, such as the Power Plate MOVE , go ahead and take the following steps:

• Stand on it with your feet shoulder-width apart – Turn it on the “low” setting for at least the first few sessions as you get used to the feeling of vibration. Bend slightly at the knees and let the vibration do its work. Benefits start from just a few minutes a day.
• Expand your movements – Once you’ve gotten used to the vibrations, you can start to make your movements more complex. Try shifting your weight from foot to foot, doing light simple dance moves, or stretching. 
• Incorporate strength training exercises – The final stage is to start performing actual exercises (this really gets your muscle fibers sizzling). Squats, toe touches, calf raises, or front lifts are all strong options. Try and keep your core tight throughout.

Safety Precautions

Vibration plates are a safe form of exercise for people of a wide range of ages and levels of fitness. With that said, you should always consult with your doctor to ensure that you are cleared for exercise and do not have preexisting conditions that would preclude you from using whole body vibration devices . Anyone with chronic health problems or injuries, first speak with their doctor before using vibration devices.

Even though vibration plates offer enormous benefits, you don’t want to overuse them. A few minutes a day is an ideal place to start—exceeding more than 15 minutes in any one session is not recommended, and always listen to your body. If something starts to hurt or not feel right, take a break. If you’re still asking yourself if vibration plates are dangerous , be sure to read our extensive article covering the topic.
