Physical Activity

First, exercise provides many health-related benefits and is one of the most important countermeasures you can rely on to prevent chronic disease and reduce overall risk of mortality. However, sometimes the effectiveness of exercise for weight loss is oversold, and people may overestimate how effective it will be toward their goal of losing weight.

Therefore, it's important for people to understand how to incorporate exercise into their weight management plan in a way that doesn't lead to one step forward and two steps back.

Being regularly active and taking part in structured exercise activities are ways to expend more energy throughout the day — often referred to as burning more calories. A negative energy balance — more commonly referred to as a caloric deficit — is required for sustained weight loss over time.

However, exercise may not lead to as big of a deficit as you may think. Activity trackers and fitness watches often overestimate the amount of calories burned during exercise. Instead of 1, calories burned during your minute elliptical session tracked on your fitness watch, it may be closer to to calories, depending on your intensity levels.

This may lead you to miscalculate your target calories for the day and ultimately mislead you in how many calories you can consume throughout the rest of the day. One of the reasons exercise may not meaningfully reduce body weight is because people often take part in other behaviors that offset this action when they're not exercising, thus sabotaging their goal of weight loss.

Some people tend to eat more after exercise, either driven by increased hunger or as part of a behavioral reward construct. For example, a person may add in a snack or splurge on a dessert, likely preceded by the inner monologue of "I've earned this.

Research also has found that people often are less active throughout the day after a bout of activity. Again, this type of behavior may reduce the potential for a daily caloric deficit, as a person may expend less energy throughout the remaining hours of the day.

They actually burn fewer overall calories than if they hadn't exercised at all. Researchers have found that dietary change is a more effective and time-efficient strategy for promoting substantial weight loss and maintenance over time. Let's face it, making time to work out throughout the week is hard.

It takes time and discipline to change your clothes, go to the gym, exercise for an hour, shower and head back to work or home for the day. Not only is it hard to do once, but to follow this routine five to seven days a week over several weeks to months is even harder. This is a lot of effort to burn an extra to calories during exercise, especially if you negate these hard-earned and burned calories by indulging at your next meal.

What took you over a few hours of time with travel, preparation and exercise can be offset in minutes by making the wrong choice in the kitchen. The type of exercise you do is important, as well. Strength training is an effective form of exercise for building lean body mass, which can improve weight loss and overall appearance.

This improved body composition often is a common goal of many people who set out to lose weight. Yes, losing weight can be important, particularly if you are overweight or obese, but it is just as important to focus on the type of weight you lose.

Is it a waste of time and effort? Overestimated caloric deficits Being regularly active and taking part in structured exercise activities are ways to expend more energy throughout the day — often referred to as burning more calories.

Physical Activity for a Healthy Weight | Healthy Weight, Nutrition, and Physical Activity | CDC

Though people often use physical activity and exercise interchangeably, the terms have different definitions. Experts measure the intensity of physical activity in metabolic equivalents or METs.

One MET is defined as the calories burned while an individual sits quietly for one minute. For the average adult, this is about one calorie per every 2. Moderate-intensity physical activity is defined as activities that are strenuous enough to burn three to six times as much energy per minute as an individual would burn when sitting quietly, or 3 to 6 METs.

Vigorous-intensity activities burn more than 6 METs. This method is not entirely reliable: Studies that measure physical activity more objectively, using special motion sensors called accelerometers , suggest that people tend to overestimate their own levels of activity. Worldwide, people are less active today than they were decades ago.

While studies find that sports and leisure activity levels have remained stable or increased slightly, 7 — 10 these leisure activities represent only a small part of daily physical activity.

Physical activity associated with work, home, and transportation has declined due to economic growth, technological advancements, and social changes. The flip side of this decrease in physical activity is an increase in sedentary activities-watching television, playing video games, and using the computer.

Weight gain during adulthood can increase the risk of heart disease, diabetes, and other chronic conditions. The latest evidence suggests that the recommended two and a half hours a week may not be enough. Researchers found that women in the normal weight range at the start needed the equivalent of an hour a day of moderate-to-vigorous physical activity to maintain a steady weight.

Vigorous activities seem to be more effective for weight control than slow walking. Although women gained, on average, about 20 pounds over the course of the study, those who increased their physical activity by 30 minutes per day gained less weight than women whose activity levels stayed steady.

And the type of activity made a difference: Bicycling and brisk walking helped women avoid weight gain, but slow walking did not. Exercise can help promote weight loss, but it seems to work best when combined with a lower calorie eating plan.

All study volunteers were asked to stick to their usual diets. After six months, those assigned to the high-intensity regimen lost abdominal fat, whereas those assigned to the low- and medium-intensity exercise regimens had no change in abdominal fat. More recently, researchers conducted a similar trial with post-menopausal women, randomly assigning them to either 45 minutes of moderate-to-vigorous aerobic activity, five days a week, or to a control group.

Most of the women were overweight or obese at the start of the study. After one year, the exercisers had significant decreases in body weight, body fat, and abdominal fat, compared to the non-exercisers. Researchers believe that physical activity prevents obesity in multiple ways: Being moderately active for at least 30 minutes a day on most days of the week can help lower the risk of chronic disease.

But to stay at a healthy weight, or to lose weight, most people will need more physical activity-at least an hour a day-to counteract the effects of increasingly sedentary lifestyles, as well as the strong societal influences that encourage overeating.

People are less likely to be active if they live in sprawling suburbs designed for driving or in neighborhoods without recreation opportunities. World Health Organization.

Or you could do 75 minutes of vigorous-intensity aerobic activity each week, such as swimming laps. The exact amount of physical activity needed to maintain a healthy weight varies greatly from person to person.

You may need more than the equivalent of minutes of moderate-intensity activity a week to maintain your weight.

To lose weight and keep it off: You will need a high amount of physical activity unless you also adjust your diet to reduce the number of calories you eat and drink. Getting to and staying at a healthy weight requires both regular physical activity and a healthy eating plan.

Pediatrics September ; 3 : e Children and adolescents may participate in sports that favor a particular body type.

Some sports, such as gymnastics, dance, and distance running, emphasize a slim or lean physique for aesthetic or performance reasons. Participants in weight-class sports, such as wrestling and martial arts, may attempt weight loss so they can compete at a lower weight class.

Other sports, such as football and bodybuilding, highlight a muscular physique; young athletes engaged in these sports may desire to gain weight and muscle mass. This clinical report describes unhealthy methods of weight loss and gain as well as policies and approaches used to curb these practices.

The report also reviews healthy strategies for weight loss and weight gain and provides recommendations for pediatricians on how to promote healthy weight control in young athletes.

Young athletes who participate in sports that favor a particular body type may express a desire to lose or gain weight. In aesthetic sports, such as gymnastics, figure skating, and diving, athletes may believe they will be judged more favorably if they have a lean body build.

With other sports, distance running and cycling, for example, participants with a slim physique are perceived to have a greater ability to move the body against gravity if they weigh less.

For weight-class sports, including wrestling and martial arts, athletes often desire to compete at the lowest possible weight in the belief that lighter athletes have an increased strength-to-weight ratio Table 2.

Football and powerlifting are examples of sports that highlight a muscular physique Table 3. Children and adolescents who participate in sports that emphasize strength and power often attempt to gain weight and lean muscle mass to improve performance. Participants in bodybuilding may seek to increase muscle mass and definition for aesthetic reasons.

In their attempts to change body weight and composition, some athletes resort to unhealthy weight-control practices. Pediatricians should have an awareness of safe and unsafe weight-control practices so they can counsel young athletes and family members appropriately. Data on the effects of collegiate and high school rule changes are also included.

Athletes may attempt to lose weight to enhance performance, to qualify for a particular weight class, or to change their appearance for a sport that emphasizes a lean physique.

Table 4 lists healthy and unhealthy weight loss methods. Some weight loss methods can lead to serious physical and psychological harm. Additionally, certain weight loss practices impair athletic performance and increase injury risk. Weight loss may initially improve athletic performance because of an increase in the strength-to-weight ratio.

However, continued use of inappropriate weight loss methods can result in reduced muscle strength, reduced performance in aerobic activities, decreased mental and cognitive performance, mood changes, depression, compromised immune response, and changes in the cardiovascular, endocrine, gastrointestinal, renal, and thermoregulatory systems.

The term hypohydration refers to the state of suboptimal hydration, and dehydration describes the transition from a well-hydrated to a hypohydrated state.

Using these tactics over the course of several days can lead to progressive dehydration because many athletes fail to fully rehydrate each day.

Dehydrated athletes often experience mental status and cognitive changes Table 5. Poor hydration status is also associated with impaired performance on the Sports Concussion Assessment Tool, an instrument used to assess mental status and symptoms after concussion.

Adapted from Weber AF, Mihalik JP, Register-Mihalik JK, Mays S, Prentice WE, Guskiewicz KM. Dehydration and performance on clinical concussion measures in collegiate wrestlers. J Athl Train. Effects of voluntary fluid intake deprivation on mental and psychomotor performance.

Croat Med J. The influence of exercise and dehydration on postural stability. In , over the course of 33 days, 3 college wrestlers died as a result of attempting drastic weight loss before competition.

Additionally, the NCAA established a system of setting a minimum weight for competition during the wrestling season by using a calculation that incorporates hydration status based on urine specific gravity , weight, and body composition. Before the competition season, athletes submit a urine sample from a witnessed collection for testing.

If the urine specific gravity is 1. Body fat is measured by using 1 of 3 methods: skin fold caliper measurement by a trained evaluator, hydrostatic underwater weighing, or air displacement plethysmography commonly performed by using a Bod Pod device.

Body fat and weight are entered into an online optimal performance calculator and are used to calculate the lowest allowable weight LAW by using 2 different methods. The LAW2 accounts for the 1. The highest of these calculated weights is the lowest weight allowed for competition during the wrestling season.

In the high school wrestling arena, the Wisconsin Interscholastic Athletic Association was the first state high school athletic association to implement a plan to curtail weight cutting among high school wrestlers.

High school wrestlers must have a urine specific gravity of 1. As with NCAA athletes, high school wrestlers may lose no more than 1.

Additionally, there is a 2-lb growth allowance for each weight class per season. High schools are permitted to use bioelectrical impedance analysis as an alternative to skin fold caliper and air displacement options to determine body fat percentage. The establishment of minimum competition weight rules has led to a decrease in the practice of rapid weight loss before competition.

Additionally, consuming a large quantity of plain water over a short period of time leads to lower serum osmolality and increased urine output and dilution. There is no agreed-on gold standard for the assessment of body composition.

Skinfold measurement is an inexpensive, well-validated method that is commonly used in the high school and collegiate setting to determine body composition. However, skinfold measurement requires trained personnel and may not be as accurate for individuals with obesity. High schools are allowed to use bioelectrical impedance analysis to measure body fat percentage; this technique is less accurate than others, and hydration status can affect the results.

Body composition is most accurately calculated with serial measurements that use the same assessment technique performed by an experienced health care provider, such as an exercise physiologist, athletic trainer, registered dietitian nutritionist RDN , or sports medicine physician. Changing the timing of precompetition weigh-ins to immediately before matches has been proposed as a means of decreasing the incentive to cut weight.

Many athletes attempt to lose weight by restricting energy caloric intake. Athletes typically need a greater caloric intake than nonathletes.

Unhealthy weight loss behaviors occur along a continuum. At the other end of the spectrum are athletes engaging in dangerous weight loss practices that carry a high risk of associated morbidity and mortality; this extreme includes children and adolescents with frank eating disorders, such as anorexia nervosa and bulimia nervosa.

Persistent weight loss via unhealthy behaviors may result in delayed physical maturation, growth impairment, and the development of eating disorders. When first described, the 3 facets of the triad included disordered eating, amenorrhea, and osteoporosis. A small body of research supports the concept that male athletes also appear to be susceptible to inadequate energy availability and may experience adverse health consequences as a result.

A survey of female high school athletes revealed that one third had disordered eating; disordered eating was correlated with an increased risk of musculoskeletal injury. Although female athletes have the highest rates of eating disorders, male athletes are also at risk.

The AAP Preparticipation Physical Examination monograph contains a history form for use during preparticipation evaluation.

aspx and includes questions designed to screen for disordered eating and menstrual irregularities. BMI less than the fifth percentile, BMI less than Education of athletes, parents, and coaches about unhealthy weight loss behaviors and their negative impact on health and athletic performance is important to prevent adverse health effects.

For non—weight-class sports, coaches should promote healthy eating habits and be alert to unhealthy eating habits in their athletes. Coaches of weight-class sports should discourage unhealthy weight-control methods and encourage athletes to compete at a weight that is appropriate for their age, height, physique, and stage of growth and development.

Many coaches inappropriately focus on weight instead of performance. In addition, coaches generally do not have an adequate nutritional background to counsel an athlete about weight loss.

Athletes should focus on optimizing energy availability for maximizing performance and good health. Female athletes with menstrual dysfunction require an evaluation to determine the underlying etiology.

If low energy availability is the cause, increasing energy intake will generally lead to resumption of normal menses. Referral to an RDN may be of benefit to assist athletes with a well-designed, healthy weight loss program or to provide guidance on increasing caloric intake, when appropriate.

The AAP has published clinical reports that outline guidance for the prevention and treatment of obesity for all children and adolescents. For most children and adolescents, the goal of weight management should be to keep BMI below the 85th percentile.

Recommendations for weight maintenance and weight loss are based on the degree of obesity. Excessive body fat may interfere with acclimation to heat and negatively affect speed, endurance, and work efficiency. Because weight is not an accurate indicator of body fat, lean muscle mass, or performance, athletes should focus on maintaining lean muscle mass.

An imbalance between energy intake and energy expenditure can result in the loss of lean muscle mass, which can negatively affect performance.

Athletes should avoid cyclic weight fluctuations. Once desired body composition and weight are achieved, dietary, exercise and lifestyle behaviors should focus on maintenance, with allowances for growth.

Gradual weight loss appears to confer greater performance benefits than rapid weight loss. A study of athletes engaged in strength training demonstrated that weight reduction of 0. Adult athletes generally require a minimum of kcal per day, but this can vary widely depending on sex and level of activity.

Type and intensity of physical activity will also influence caloric needs. Young athletes attempting to lose weight may benefit from the guidance of a RDN with sports nutrition experience. Athletes involved in sports such as football, rugby, power lifting, and bodybuilding may desire to gain weight and lean muscle mass to improve power and strength or to achieve a muscular physique.

Preadolescent and adolescent athletes who want to gain weight may require guidance about appropriate, healthy strategies for achieving their goals.

Table 7 lists healthy and unhealthy methods of weight gain. Increasing caloric intake in the form of food consumption or use of dietary supplements may lead to excessive fat accumulation rather than the desired increase in lean muscle mass.

Supplement manufacturers are not required to prove safety before bringing their products to the market. Many supplements, even those sold by national retailers, contain unlisted, potentially harmful ingredients.

Adolescent males who perceive themselves as under- or overweight are nearly 4 times more likely to use anabolic steroids to attempt to change body composition as compared with those who perceive themselves as being at an appropriate weight. Summary of Performance-Enhancing Substances Commonly Used by Athletes With Effects on Performance and Possible Adverse Effects.

Modified from LaBotz M, Griesemer BA; Council on Sports Medicine and Fitness. AAP Clinical Report: Use of Performance Enhancing Substances. AAS, anabolic-androgenic steroid; DHEA, dehydroepiandrosterone; hGH, human growth hormone; HMB, hydroxymethyl butyrate; IGF-1, insulin-like grow factor 1; —, not applicable.

Young athletes in sports in which a muscular physique is valued for aesthetic or performance reasons may seek to gain weight and increase lean body mass through a combination of increased caloric intake and strength training. Female athletes and prepubertal male athletes typically increase strength with a weight-training program but generally do not have sufficient circulating androgens to increase muscle bulk considerably.

To increase muscle mass, athletes must consume sufficient calories and include adequate proteins, carbohydrates, and fats. Increased energy intake should always be combined with strength training to induce muscle growth.

Children and adolescents who wish to engage in strength training should begin by learning proper technique without resistance. Weight loads should be increased gradually; programs should incorporate 2 to 3 sets of 8 to 15 repetitions with the athlete maintaining proper technique.

Although weight-training programs for children and adolescents have health and athletic performance benefits, the AAP recommends that skeletally immature children and adolescents avoid power lifting, bodybuilding, and maximal lifts.

BMI, defined as weight in kilograms divided by height in meters squared, 2 is a commonly applied screening tool used as a measure to assess general health. BMI values between the 5th and 85th percentile for age are considered normal.

The Centers for Disease Control and Prevention has published BMI charts that categorize BMIs on the basis of sex and age. Approximately one-third of adults classified as having obesity on the basis of BMI measurement have good cardiac and metabolic health on the basis of other variables, such as blood pressure, cholesterol concentrations, and insulin resistance.

An increased torso-to-leg ratio also results in increased BMI. In adolescents, increased weight gain and increased height velocity during puberty may not coincide, resulting in temporary elevation or depression of BMI. Although there are normative data for body fat percentage, there are no established recommendations regarding body composition in children and adolescents.

These minimums are well under the fifth percentile for body fat observed in the general adolescent population. Rather than suggesting a specific percentage of body fat for an individual athlete, a range of values that is realistic and appropriate should be recommended.

Physicians who care for young athletes are encouraged to have an understanding of healthy and unhealthy weight-control methods;. Health supervision visits for young athletes generally include history-taking to ascertain diet and physical activity patterns. When discussing diet and exercise, physicians can encourage parents of young athletes to place nutritional needs for growth and development above athletic considerations.

Acute weight loss through dehydration and the use of potentially harmful medications and supplements for weight control should be strongly discouraged;. Physicians should counsel young athletes who express a desire to gain or lose weight to avoid weight-control methods that may have adverse health effects, such as acute weight loss through dehydration and the use of potentially harmful medications and supplements.

Many of these methods may have a negative effect on performance as well;. Some states require a specific form for sports preparticipation examinations.

For physicians in states without a specific requirement, the AAP Preparticipation Physical Examination monograph contains a standardized history-taking form that may be helpful for screening athletes.

It can also lower the risk of heart disease, diabetes, stroke, high blood pressure, osteoporosis, and certain cancers, as well as reduce stress and boost mood.

Inactive sedentary lifestyles do just the opposite. Despite all the health benefits of physical activity, people worldwide are doing less of it-at work, at home, and as they travel from place to place. Globally, about one in three people gets little, if any, physical activity.

The World Health Organization, the U. of Health and Human Services, and other authorities recommend that for good health, adults should get the equivalent of two and a half hours of moderate-to-vigorous physical activity each week. This article defines physical activity and explains how it is measured, reviews physical activity trends, and discusses the role of physical activity in weight control.

Though people often use physical activity and exercise interchangeably, the terms have different definitions. Experts measure the intensity of physical activity in metabolic equivalents or METs. One MET is defined as the calories burned while an individual sits quietly for one minute.

For the average adult, this is about one calorie per every 2. Moderate-intensity physical activity is defined as activities that are strenuous enough to burn three to six times as much energy per minute as an individual would burn when sitting quietly, or 3 to 6 METs.

Vigorous-intensity activities burn more than 6 METs. This method is not entirely reliable: Studies that measure physical activity more objectively, using special motion sensors called accelerometers , suggest that people tend to overestimate their own levels of activity.

Worldwide, people are less active today than they were decades ago. While studies find that sports and leisure activity levels have remained stable or increased slightly, 7 — 10 these leisure activities represent only a small part of daily physical activity.

Physical activity associated with work, home, and transportation has declined due to economic growth, technological advancements, and social changes.

The flip side of this decrease in physical activity is an increase in sedentary activities-watching television, playing video games, and using the computer. Weight gain during adulthood can increase the risk of heart disease, diabetes, and other chronic conditions.

The latest evidence suggests that the recommended two and a half hours a week may not be enough. Researchers found that women in the normal weight range at the start needed the equivalent of an hour a day of moderate-to-vigorous physical activity to maintain a steady weight.

Vigorous activities seem to be more effective for weight control than slow walking. Although women gained, on average, about 20 pounds over the course of the study, those who increased their physical activity by 30 minutes per day gained less weight than women whose activity levels stayed steady.

And the type of activity made a difference: Bicycling and brisk walking helped women avoid weight gain, but slow walking did not. Exercise can help promote weight loss, but it seems to work best when combined with a lower calorie eating plan.

All study volunteers were asked to stick to their usual diets. After six months, those assigned to the high-intensity regimen lost abdominal fat, whereas those assigned to the low- and medium-intensity exercise regimens had no change in abdominal fat. More recently, researchers conducted a similar trial with post-menopausal women, randomly assigning them to either 45 minutes of moderate-to-vigorous aerobic activity, five days a week, or to a control group.

Most of the women were overweight or obese at the start of the study. After one year, the exercisers had significant decreases in body weight, body fat, and abdominal fat, compared to the non-exercisers. Researchers believe that physical activity prevents obesity in multiple ways: Being moderately active for at least 30 minutes a day on most days of the week can help lower the risk of chronic disease.

But to stay at a healthy weight, or to lose weight, most people will need more physical activity-at least an hour a day-to counteract the effects of increasingly sedentary lifestyles, as well as the strong societal influences that encourage overeating. People are less likely to be active if they live in sprawling suburbs designed for driving or in neighborhoods without recreation opportunities.
