Healthy nutrition and maintaining a normal body weight are very important for reducing the risk of various diseases not only among the general population, but also among athletes, especially combat sport athletes. The aim of the study was to evaluate the prevalence of rapid weight loss (RWL) and to indicate eventual dietary inadequacies among professional martial arts practitioners. Sixty-two male athletes (aged: 23 ± 4) completed a questionnaire (i.e., frequency of food group consumption, questions about training and RWL) and single 24-h dietary recall. This study confirmed the high prevalence of RWL in athletes (58%) for two to three days before the competition, which allowed for reduction of 3.4 ± 1.0 kg (4.3 ± 1.5%) of their body weight. Many dietary inaccuracies were found such as: lower than recommended by nutrition experts, level of consumption of dairy products, grain products, fruit, and vegetables, and insufficient intake of energy, carbohydrates, minerals (especially iodine, potassium, calcium) and vitamins (especially D, folate, C, E) during the training day. Adequate nutrition is a natural support for the whole training process, and may allow for regulation of body weight in a longer period and in a safer manner; thus, there is a need for nutrition education dedicated to athletes and their trainers.

Background: A group that is particularly exposed to eating disorders are young sportswomen who practice aesthetic disciplines, for whom it is important to keep a slim figure. Hence, the purpose of the study was to present the assessment of perception of one’s own body and self as well as nutritional behavior in the group of ballet dancers and artistic gymnasts (BGA, n = 60) aged 10–12 against the background of the peer group (K, n = 60) and to determine the relationship between the studied elements, as well as anorexic readiness risk assessment to help diagnose premorbid stage of eating disorders with full symptoms. Methods: Anthropometric measurements (height, body weight) and the assessment of adipose tissue were performed. Using a questionnaire, data on physical activity, perception of one's own body and self, and selected eating behaviors were collected. Results: Underweight was observed in nearly half of the girls from the BGA group and the content of adipose tissue was significantly lower. Girls from the BGA group were characterized by overestimation of body size (p = 0.032), the need to improve their appearance/body (p = 0.025) and wanting to be the best in many areas of life (p = 0.002) significantly more often than in the K group. Moreover, they significantly more often limited the consumption of fats and carbohydrates (p = 0.044) and felt angry with themselves after too large of a meal (p = 0.050). It was shown that unhealthy eating behavior in the BGA group was significantly associated with rigorous self-perception (r = 0.42; p < 0.001). Students from the BGA group were more often exposed to a higher risk of anorexic readiness (p = 0.001). In a detailed analysis, it was found that eating behaviors, such as fasting, limiting the consumption of fats and carbohydrates, and avoiding eating under stress, were associated with feelings of dissatisfaction with oneself, the belief that appearance is extremely important in achieving life success and the need to improve appearance. Conclusion: The obtained research results can be used as a source of information for specialists (including dietitians and psychologists), for the preparation of educational and repair programs in the group of ballet dancers or artistic gymnasts aged 10–12, including nutritional education and psychological care.

Background: Adherence to nutritional recommendations in groups of adolescents practicing various sports, including esthetic disciplines, is insufficient. Hence, the authors of this study attempted to design, implement and evaluate a nutritional education program for girls aged 10–12 attending a ballet school and artistic gymnastics classes. Methods: The study was conducted with 60 female students at the state ballet school and artistic gymnastics classes (professionally practicing ballet and artistic gymnastics). The nutritional education program was implemented by all students for a period of 4 weeks. The program consisted of three parts: group sharing and discussing the educational brochure, group nutritional workshops, and providing and discussing individual nutritional recommendations. Information provided to students during the nutritional education program concerned the principles of proper nutrition contained in the Pyramid of Healthy Nutrition and Physical Activity for Children and Youth, the most important sources of nutrients in the diet and their role, and the principles of nutrition of people practicing sports/training. Before starting the nutritional education program and 3 months after its completion, the level of nutritional knowledge was assessed in the group of ballerinas and artistic gymnasts to evaluate the program. Results: The proposed nutritional education program had a significant impact on the level of nutritional knowledge of students aged 10–12 attending the ballet school and artistic gymnastics classes. Conclusions: The presented nutritional education program may be used as a source of information for specialists for the preparation of educational and repair programs in the group of ballet dancers or artistic gymnasts aged 10–12.
