Sažetak
The purpose of this study was to assess dietary intake and body composition of prepubescent girls competing in 3 different aesthetic sports (artistic gymnastic, rhythmic gymnastic and ballet dancing). The sample consisted of 39 aesthetic athletes (median age: 11 years, range 9-13) and 15 controls (median age: 11 years, range 10-12). Since physiologic demands during ballet training are similar to the demands in other aesthetic sports, ballet dancers were, for the purpose of this study, regarded as athletes. Dietary intake was assessed using a quantitative food frequency questionnaire and body composition by means of anthropometry. There was no significant difference in total energy intake between groups, but there was a significant difference in energy substrate distribution. Artistic gymnasts reported significantly higher carbohydrate and lower fat contribution to total energy (57± ; ; 6% and 29± ; ; 5%, respectively) than rhythmic gymnasts (48± ; ; 6% and 36± ; ; 5%), ballet dancers (51± ; ; 4% and 34± ; ; 3%) or controls (51± ; ; 5% and 34± ; ; 4%). Relative to body weight, artistic gymnasts reported higher intake of carbohydrates (9.1± ; ; 4.2 g/kg) than rhythmic gymnasts (5.6± ; ; 3.1 g/kg), ballet dancers (6.6± ; ; 2.5 g/kg) or controls (5, 4± ; ; 1, 9 g/kg). This group of artistic gymnasts also had the lowest body fat percentage among the groups assessed. In all the groups mean reported daily intakes of most nutrients were higher than the current DRI’ s. The exceptions were mean intakes of dietary fiber and calcium. Considering the reported intakes of vitamins and minerals, the proportion of athletes with an inadequate reported intake was highest for phosphorus (33%), followed by vitamin A and niacin (18%) and zinc (13%).
