Each recommendation is followed by a letter describing the level of evidence found in the literature supporting the recommendation: A means there are well-designed experimental, clinical, or epidemiologic studies to support the recommendation B means there are experimental, clinical, or epidemiologic studies that provide a strong theoretical rationale for the recommendation and C means the recommendation is based largely on anecdotal evidence at this time. ![]() The recommendations are categorized using the Strength of Recommendation Taxonomy criterion scale proposed by the American Academy of Family Physicians 6 on the basis of the level of scientific data found in the literature. These recommendations are built on the premise that scientific evidence supports safe and effective weight loss and weight management practices and techniques, regardless of the activity or performance goals. 5īased on the current research and literature, the National Athletic Trainers' Association (NATA) suggests the following safe weight loss and weight maintenance strategies for participants in all sports and physical activities. 4 Although lean body mass has been associated with positive health benefits, negative health outcomes are associated with excessive loss or gain of body mass. ![]() 3 In females, lower body fat may also protect against breast and other reproductive cancers. ![]() In addition to the potential performance benefits of lean body mass and lower levels of body fat, long-term health benefits include decreased cardiovascular risk factors, reduced triglyceride concentration, possible increases in cardioprotective high-density lipoprotein cholesterol concentration, increased fibrinolysis, reduced resting blood pressure, reduced resting glucose and insulin, and increased insulin sensitivity. In 2005, the American Academy of Pediatrics 2 published a general weight control practice guide for children and adolescents involved in all sports. Yet the governing organizations of these activities have no mandated weight control practices. In activities such as dance, distance running, gymnastics, and cycling, weight and body composition are believed to influence physical performance and the aesthetics of performance. Weight classifications in sport (eg, youth football, wrestling, rowing, boxing) were designed to ensure healthy, safe, and equitable participation 1 however, not all sports or activities in which weight might play a role in performance use a weight classification system. Athletes, clients, parents, and coaches should be educated on how to determine safe weight and body composition so that athletes and clients more safely achieve competitive weights that will meet sport and activity requirements while also allowing them to meet their energy and nutritional needs for optimal health and performance. All weight management and exercise protocols used to achieve these goals should be safe and based on the most current evidence. In some cases, a registered nutritionist may have equivalent credentials and be the commonly used term. In keeping with the American Dietetics Association (ADA) preferred nomenclature, this document uses the terms registered dietitian or dietician when referring to a food and nutrition expert who has met the academic and professional requirements specified by the ADA's Commission on Accreditation for Dietetics Education. Reasonable and individualized weight and body composition goals should be identified by appropriately trained health care personnel (eg, athletic trainers, registered dietitians, physicians). Body composition assessments should be done in the most scientifically appropriate manner possible. Athletic trainers are often the source of nutrition information for athletes and clients therefore, they must have knowledge of proper nutrition, weight management practices, and methods to change body composition.
