Weight management for sports -
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.
This form is also available on the AAP Web site and includes questions designed to screen for disordered eating and menstrual irregularities. Physicians are encouraged to engage the services of RDNs familiar with athletes to help with complex weight-control issues, if these providers are available in their communities.
Monitoring athletes with weight-control issues every 1 to 3 months can aid the physician in detecting excessive weight loss;. There are no established recommendations for body fat percentages in adolescent athletes. 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 should counsel young athletes that weight gain or weight loss regimens should be initiated early enough to permit gradual weight change before a sport season.
Slow weight gain, in combination with strength training, will decrease gain of body fat. Slow weight loss in the athlete with excess body fat will decrease loss of muscle mass. A well-balanced diet is recommended for all athletes. Once the desired weight is obtained, the athlete should attempt to maintain a constant weight; and.
When opportunities for community education arise, pediatricians should collaborate with coaches and certified athletic trainers to encourage healthy eating and exercise habits.

This can create enormous confusion and has the potential to undo all the hard training that athletes put in if they take the wrong approach or look for quick fixes. The goal of most if not all weight loss plans is to create a negative energy balance where more energy is used than consumed by the body.
There are many ways to achieve a negative energy balance and often diets promote cutting out entire food groups particularly carbohydrates and dairy foods to do this. While this might result in some quick weight loss initially, unfortunately, this loss is usually short term and unsustainable and weight lost is quickly regained.

Make sure to incorporate at least strength training sessions into your training regimen to build strength, reduce the risk of injury, and maintain lean body mass [9]. Losing weight can make training feel more difficult and sometimes hinder performance, especially if it involves loss of lean muscle mass.
For the casual athlete looking to lose a few pounds, you may slim down just by exercising more regularly or training for an upcoming race. For the more competitive athlete, dieting during peak training season can have some serious consequences. Research shows calorie restriction during training can not only impede performance but lead to significant losses of lean muscle mass, physical and psychological symptoms of overtraining, and illness [6].
For this reason, serious athletes should focus on eating for performance during peak training periods to maximize training effects and to maintain body weight and health.
Serious weight loss is best saved for the off-season when energy and performance demands are lower [ 5. Rapid weight loss can have several negative effects on hormones, metabolism, and body composition.
While you may hit your weight loss goals faster, large caloric deficits come at a cost, including greater losses of lean body mass and compromised athletic performance and recovery [7].
As you get leaner, slower rates of weight loss can better preserve lean body mass, which is crucial to performance [2]. Crash diets are a recipe for disaster, but evidence suggests time-restricted feeding TRFa form of intermittent fasting, may be better for weight loss than daily calorie restriction.
Studies show intermittent fasting diets, particularly TRF, perform equally to or better than daily calorie restriction for improving body composition [2]. Unlike other types of intermittent fasting that involve calorie restriction, time-restricted feeding allows you to eat as much as you want during that hour window.
Many find time-restricted feeding less restrictive and easier to stick with since all foods are fair game, and a significant portion of the fasting window happens while you sleep.
Start with a hour overnight fast and increase as tolerated to hours. Ideally, do your workout in the middle of your eating window, so you have some fuel in the tank and can adequately refuel after.
If you have diabetes or low blood sugar, chat with your doctor or dietitian about trying TRF safely. Modestly reducing calorie intake while maintaining a high-carbohydrate, high-protein diet weight during peak training periods [ 1.
Consuming 1. Staying well hydrated throughout the day and before, during, and after training. Prioritizing pre-and post-workout nutrition specifically carbohydrates, protein, and fluid intake to optimize performance and recovery.
Losing weight does affect endurance. Research shows aerobic endurance capacity decreases after rapid weight loss but might increase after gradual weight loss [ 1. Losing weight affects strength. Research shows muscle strength and anaerobic performance typically decrease after rapid weight reduction, whereas performance is not affected, and strength can increase after gradual weight loss [ 1.
Slower rates of weight loss can better preserve lean body mass and minimize performance losses, so the lower the calorie deficit and slower the weight loss, the better. To lose weight, athletes need complex carbohydrates, including whole grains, fruits, and vegetables, and lean protein, like fish, chicken, turkey, eggs, reduced-fat dairy, and tofu, as these foods support both athletic performance and weight loss.
It is possible to lose weight without sacrificing athletic performance, as gradual weight loss may even lead to improvements in both strength and endurance. Just remember, serious weight loss should be saved for the off-season, and a slow, sustainable approach will give you the best results.

| Background | There are many ways to achieve a negative energy balance and often diets promote cutting out entire food groups particularly carbohydrates and dairy foods to do this. While this might result in some quick weight loss initially, unfortunately, this loss is usually short term and unsustainable and weight lost is quickly regained. Diets that eliminate whole food groups or are heavily energy restricted can also negatively impact performance by impairing fuelling and recovery, preventing athletes from achieving their potential during training or competition. They can also impair immune function and increase injury risk, meaning that valuable training sessions or events are missed due to illness or injury. There is more than one way to achieve your body composition and weight goals. Working with an Accredited Sports Dietitian is an important first step in making sure you have an individualised plan that works for you without compromising your performance.

| Physical Activity for a Healthy Weight | 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.

Although competitive success is multifactorial and too complex to be determined by one variable, the associations provided by these investigations are insightful and help discern the impact of RWL on competitive performance. In a regional-level wrestling competition, it was observed that athletes who lost a higher amount of weight achieved better classification than the athletes who lost less weight [ 34 ]. Thus, athletes who had practiced more aggressive weight cutting procedures presented better competitive results as compared to those who were more conscious with their health. Studies performed in national level competitions have produced conflicting data. In a study by Horswill et al. Assuming that the body mass recovered after weigh-in is associated with body mass reduced before the weigh-in, the authors concluded that the amount of weight lost and, consequently, the amount of weight regained after the weigh-in has no effect on competitive success. In contrast, Alderman et al. Some authors [ 8 ] argue that a successful career is probably built in a single weight class. Despite the paucity of evidence that indicates an association between rapid weight loss and competitive success [ 5 , 14 ], it must be noted that it is possible to achieve success in combat sports while competing in multiple weight classes. Some prime examples are the successful athletes who moved to heavier weight classes and still performed at the highest level e. While studies are scarce and inconclusive, the impact of RWL on competitive success remains elusive, especially when considered the great number of variables defining wins and losses. Despite conflicting evidence, most studies indicate that weight loss decreases both aerobic and anaerobic performance. While aerobic performance impairments have been attributed to dehydration, decreased plasma volume, increased heart rate, hydroelectrolytic disturbances, impaired thermoregulation and muscle glycogen depletion [ 30 ], decreased anaerobic performance is mainly related to reduced buffering capacity, glycogen depletion and hydroelectrolytic disturbances [ 30 , 35 ]. Maximal strength seems to not be acutely affected by RWL [ 36 — 38 ], although chronic weight cycling has a negative impact on strength gain during a season [ 39 ]. It is important to highlight that the decrements on anaerobic performance are generally observed when athletes have no opportunity to refeed and rehydrate after weigh-in [ 27 , 38 , 40 , 41 ]. However, in the most combat sports competitions, weigh-ins are followed by a period of time during which athletes may have the chance to recover from the weight loss. Although this period may vary from a few hours to more than one day, it is very likely that within 3—4 hours, athletes are able to recover their anaerobic performance to pre-weight loss values [ 9 ]. Therefore, when followed by a relatively short recovery period, RWL will probably have minimal or no impact on anaerobic performance. Although this seems to be true for athletes who are experienced weight cyclers, athletes with no experience in reducing weight might be negatively affected by weight loss [ 42 , 43 ]. It suggests that weight cycling may lead athletes to develop physiological adaptations that help them to preserve performance after weight loss. However, to date there is no direct evidence supporting these hypothesis and further studies are needed to confirm or refute them. Some epidemiological studies have associated RWL with increase risk for injuries [ 44 ]. Oöpik et al. Due to the possible adverse effects of RWL, there are rare cases of death related to this practice. In , just three months before Atlanta Olympic Games, Chung Se-hoon 22 years, 74 kg , considered the probable gold medal winner in the 65 kg weight category in judo, was found dead in a sauna. The c ausa mortis was a heart attack. One year later, three collegiate wrestlers died due to hyperthermia and dehydration associated with intentional RWL [ 47 ]. During the Sydney Olympics, Debbie Allan from Great Britain was disqualified during the weigh-in because the scale used by her was not calibrated due to an alleged scale sabotage [ 48 ]. The problem seems also to affect children. Those extreme cases, together with the very high prevalence of RWL achieved by aggressive methods, illustrate quite clearly that the scenario is disturbing, the problem may be more serious than many people involved with the sport may think and that more attention to this problem should indeed be given. No athlete should be encouraged to cut weight quickly in order to compete in a lighter weight class. Gradual weight loss i. Athletes should aim to maximize body fat loss and minimize muscle wasting and dehydration when adjusting weight. During the weight loss period, strength training and BCAA supplementation may help preserve muscle mass. Athletes should not undergo low-carbohydrate diets in order to make weight as they seem to be more detrimental to physical performance [ 41 ]. If an athlete will have less than 3 hours to recovery after the weigh-in, RWL, dehydration and restricted carbohydrate ingestion should be avoided. During the recovery period after weigh-in, athletes are encouraged to consume high amounts of carbohydrates, fluids and electrolytes. Creatine supplementation may also be of use if the athlete will recover for a long period after weighing-in. Control strategies to avoid RWL practices can be divided in two areas: 1 coach and athlete educational programs; 2 management procedures to control or discourage RWL. According to Burke and Cox [ 3 ], athletes and coaches should receive information about: caloric balance; how to prepare each food portion; how to avoid increase weight especially fat after the competition; how to prepare food using low fat ingredients; how to prepare snacks with low caloric content using fruits and vegetables; how to avoid combating stress through excessive food intake; how to avoid gastronomic novelties during high-level competitions abroad or when inside the Olympic village; the importance of avoiding fast-food restaurants while travelling; how to increase satiety using low glycemic index foods; how to avoid excessive food and alcohol intake during celebrations; how to keep a diet diary and how to identify the main difficulties to maintain adequate nutrition. Additionally, the recommendations done by Horswill [ 20 ] concerning body mass control during the season are important sources of information. This author suggests specific goals for each periodization phase. Management procedures have been used in wrestling [ 53 ] and proposed for judo [ 8 ] to avoid weight loss among athletes. The following recommendations were first drafted in [ 54 ] and reinforced in by the American College of Sports Medicine [ 14 ]. They are currently in use in most scholastic wrestling competitions in United States as a part of a program aiming at controlling the weight management issue among wrestlers. This program has been shown effective in attenuating the aggressive patterns of rapid weight loss and discouraging athletes from losing weight irresponsibly [ 20 ]. Therefore, these recommendations should be implemented by other combat sports organizations in order to avoid widespread weight loss among combat athletes [ 8 ]:. no athletes are allowed to compete in a weight class that would require weight loss greater than 1.
