Using these tactics over the course of several athletee can lead to ahletes dehydration because Hunger and elderly population 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.

Croat Med J. The influence of exercise and dehydration on postural stability. Inover 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 gravityweight, 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 RDNor 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.

| How does weight loss affect sports performance? | In fact, several studies show that eating 2—3 times more protein per day can help athletes retain more muscle while losing fat 9 , 16 , Therefore, athletes restricting their calories to lose weight should eat 0. Consuming more than these amounts can displace other important nutrients, such as carbs, from your diet. This can limit your ability to train and maintain good sports performance 2 , 3 , 9 , SUMMARY Higher protein intakes help limit muscle loss while your weight is dropping. Athletes should aim to consume 0. In addition to eating more protein, athletes can benefit from spreading their intake throughout the day In fact, 20—30 grams of protein per meal seems sufficient to stimulate muscles to produce protein for the following 2—3 hours. Interestingly, studies in athletes show that spreading 80 grams of protein over 4 meals stimulates muscle protein production more than splitting it over 2 larger meals or 8 smaller ones 22 , Eating a snack with 40 grams of protein immediately before bedtime can also improve recovery from training and increase muscle protein synthesis during the night SUMMARY Eating 20—30 grams of protein every 3 hours, including right before bed, may help maintain muscle mass during weight loss. Eating the right foods after training or competing is vital, especially when trying to lose body fat. Proper refueling is especially important for days with two training sessions or when you have fewer than eight hours of recovery time between workouts and events 2. Athletes following carb-restricted diets should aim to consume between 0. Adding 20—25 grams of protein can further speed up recovery and promote protein production in your muscles 2. SUMMARY Consuming a good amount of carbs and protein immediately after training can help maintain your sports performance during weight loss. Individuals attempting to lose weight are often at risk of losing some muscle in addition to fat. Athletes are no exception. Some muscle loss can be prevented by eating a sufficient amount of protein, avoiding crash diets, and lifting weights 3. Research shows that both protein intake and strength-training exercises stimulate muscle protein synthesis. Nevertheless, make sure to speak to your coach before adding any extra workouts to your schedule. This will reduce your risk of overtraining or injuries. SUMMARY Strength-training exercises can help prevent the muscle loss often experienced during a period of weight loss. Researchers believe these adaptations can persist for some time after you bump up your calorie intake and cause you to quickly regain the lost fat 5. This may help restore your hormone levels and metabolism better, minimizing the weight regain 5. SUMMARY Increasing your calorie intake gradually after a period of weight loss may help minimize weight regain. Although weight loss is a widely researched topic, the number of studies performed on athletes is limited. Nevertheless, many of the strategies scientifically proven to help non-athletes lose body fat may also benefit athletes. Thus, you can try some of the following:. SUMMARY Stress, sleep, hydration, and alcohol all affect weight loss. Eating slowly, controlling portion sizes, and sleeping well can all help you lose weight. Those who want to reduce their body fat levels should aim to do so during the off-season. Keep in mind that lower body fat is not always better. Athletes should discuss any weight loss goals or strategies with their coach or sports dietitian.

When dieting for weight loss, active individuals also want to preserve lean tissue, which means that energy restriction cannot be too severe or lean tissue is lost. First, this brief review addresses the issues of weight management in athletes and active individuals and factors to consider when determining a weight-loss goal. Second, the concept of dynamic energy balance is reviewed, including two mathematical models developed to improve weight-loss predictions based on changes in diet and exercise. These models are now available on the Internet. Emphasis is placed on teaching the benefits of consuming a low-ED diet e. |

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. 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. 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.

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. Weight Gain Gains in muscle mass will best be achieved when in positive energy balance. Muscles take time to grow so it is important to set realistic goals. Focus first on consuming adequate carbohydrates. Endurance athletes should consume at least 1. The recommended protein intake to increase skeletal muscle in strength athletes is typically 1. Consuming protein above this level does not appear to have an anabolic effect. Fat restriction should be moderate. Distribute calories evenly over the course of the day and focus on adequate fuel around exercise. The rest of us need to take action by following a detailed plan to achieve our optimal race weight. Follow this list of actions one by one until you reach the point where you are losing 0. If you are within three to five percent of your race weight, it is likely you only need to follow steps Use a food diary app or good old-fashioned pen and paper to measure your calorie intake for three days. Learn the nutrient profile of foods you are eating to make accurate dietary decisions. Track your body weight or body fat percentage in TrainingPeaks and graph it out over time using their dashboard tool. Seeing your milestones and goals achieved on a chart is motivating.

Weight management for athletes -
Each energy-yielding nutrient provides a set number of kilocalories kcal per gram g , which together determine the number of kcal or energy it provides. During the process of metabolism, energy is released, which can then be used for growth and development of new cells and tissues, digestion, absorption of nutrients, fueling working muscles and other functions.
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:. Written by SCAN Registered Dietitians RDs.

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.
