Weight management for athletes -
Student-athletes require more energy than non-athletic students in order to maintain body weight due to added energy expenditure from training.
Energy that is not used to fuel the body will be stored for later use, either as glycogen in the liver and muscles or as fat in adipose tissue. Long-term consumption of more energy than is being expended will result in an accumulation of fat in adipose tissue, and therefore unhealthy weight gain.
The opposite is also true. Eating fewer kilocalories than the body needs will result in the breakdown of stored energy and weight loss. Unfortunately, a poorly designed diet may cause the body to break down lean tissue e.
The ideal body weight and body composition will be unique to each student-athlete. Appropriate loss of body fat may be desirable for a variety of reasons related to improved performance. For example, a sprinter may want to improve their power to weight ratio or a lightweight rower may want to make weigh-in requirements.
On the contrary, some student-athletes will benefit from weight gain, specifically by increasing muscle mass to increase strength and power. Whatever the weight goal may be, it is important to be strategic with macronutrient intake.

The following are some guidelines to consider: Weight Loss Weight loss for athletes is a balancing act focusing on eating enough to support training and performance while creating an energy deficit to lose weight. Therefore, it is best to focus on weight loss during the off season or rest phase of the training cycle.
Athletes who are trying to decrease body fat may consume protein at a level of 1. Build a balanced diet focused on nutrient-dense foods such as lean proteins, beans and legumes, low-fat dairy, fruit, vegetables, and whole grains.
Do not skip meals. Instead, reduce portion sizes. 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.
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.
