Objective: To correlate body composition with dietary intake and tendency for eating disorders in female athletes between 12 and 14 years of Paranaense Rhythmic Gymnastics Team. Methods: To evaluate the body fat percentage by skinfold, food intake by dietary recall and the tendency for eating disorders by EAT, BITE and BSQ tests. Results: The athletes did not achieve the minimum recommendation of fat percentage in this age group, and 81.8% reached the average value for the sport. The consumption of more than half of the sample reached the minimum recommendation of energy, protein and lipid, reaching less than half of the minimum carbohydrate, calcium and iron. Twenty seven point one percent of the athletes had some risks for anorexia and 72.7% were out of it. Sixty three point five percent of the group presented some risks for bulimia and 36.3% low risk. Sixty three point five percent have somebody dissatisfaction and 36.6% within the normal range. There was a low correlation between dietary intake and body fat percentage, tendency to develop anorexia in athletes with body fat and high dietary intake, risk of bulimia with body fat percentage above average, body dissatisfaction with body fat above average group, with body dissatisfaction and dietary intake below the average in the group. Conclusion: The athletes presented body fat percentage lower than recommended for their age, and the normal range for events sports, inadequate dietary intake, which can lead health problems, a bigger tendency to bulimia than anorexia and body dissatisfaction.

Introduction: Martial arts practitioners promote their many benefits, both physical and mental health. Objective: To evaluate dietary and anthropometric characteristics of practitioners of a kung fu academy in Valinhos-SP. Methods: Cross-sectional study with 40 practitioners of both genders, between 18 and 30 years. Anthropometric measurements were taken: weight, height, skinfold thicknessand girth. Laterwas applied food recall 3 days 24 hours. Were analyzed the data in Avanutri software, Excel and SPSS. The protocol was approvedby the Ethics in Research/UNIP with registration 048/2011. Results: 65% of participants were male and 35% female. It was foundin men of middle age, height, weight and body mass index (BMI): 23.69 years, 1.76±0.06m, 71.01±9.39kg and 23.04±2.35kg/m (eutrophic), respectively. In women were found the following average results: 22.79 years, 1.70±0.08m, 66.40±11.56kg and BMI 23.08±3.29kg/m (eutrophic). The average fat percentage for men was10.85±4.88% and female17.73±4.37%, both ranked among "good" or "excellent”. The dietary evaluations characteristics of dietary intake of athletes hypoglycemic diet (47.6% of the total energy intake), high protein (1.30g/kg/day) and lipids (35.61% of total energy intake). Conclusions: Although the results are within normal anthropometric, dietary assessments howed the need for a nutrition education programon the importance of a balanced diet and proper practicing kung fu.

Introduction: The practice of physical exercise causes physiological changes in the body and among them the increase in the rate of production of heat and sweating. The sweat production and subsequent evaporation thermoregulatory mechanism is more efficient, however, dehydration can compromise performance. There are several ways to evaluate the changes in hydration levels after the practice of physical exercise and among them, the measure of acute changes in body weight before and after exercise. Objective: To evaluate the changes in hydration levels of marathon runners after athletics. Materials and Methods: A total of 6 athletes athletics, the national average age of 29.67 years, fit the practice of competitive exercises. The study took place in two distinct stages one another in forty-five days. In each step, each of the athletes covered a distance of 20 km around an athletics track. In the first stage each athlete received every 4 kilometers of racing 200 milliliters of water to hydrate and the second stage was not allowed to hydrate athletes during the race. Body mass was measured before and immediately after exercise. Results: The results indicate that racing occurs without hydration leads to dehydration average of 2.14% of body weight. Discussion: It has been shown that fluid losses above 2% in relation to body mass can affect performance during sports. Conclusion: The practice of athletics with distance of 20 km leads to dehydration of 2.14% of body mass, which impairs the performance of the race.
