摘　　要：Background In many sports,athletes with low body weight and/or low body fat content have a distinct advantage over their opponents.Such an advantage can easily turn into a noticeable disadvantage because low body weight and 'leanness' may also be associated with health problems.Anorexia Athletica(AA) is associated with leanness and thinness in female and male sports athletes despite the fact that these athletes are often very successful.High-competitive athletes often restrict their caloric intake and/or increase their energy expenditure to maintain a low body mass and/or a low amount of body fat.Several metabolic and endocrine disturbances are often the result of prolonged energy restriction.These disturbances can be detected by alterations in the hormonal profile(low levels of leptin,increased levels of ghrelin) and in changes in body composition.Background In many sports, athletes with low body weight and/or low body fat content have a distinct advantage over their opponents.
