Body composition of young aesthetic sport female athletes

The aim of this work was to investigate the homogeneity/heterogeneity in the body physique and composition within this relatively homogeneous premenarcheal group of 57 female athletes in three different aesthetic disciplines. Anthropometry encompassed 24 measures. Body mass index (BMI) and the body fat percentage (% fat) were calculated. The obtained data were analyzed by descriptive statistics, univariate variance analysis (ANOVA) and canonic discriminative analysis. The results show that the groups of prermenarcheal athletes do not differ significantly in height, body mass and BMI. The athletes show similarity in skeletal measures, with the exception of the ankle diameter. In other measures sensitive to specific load requirements during training process heterogeneities are significant, with the highest values expressed in figure skaters. Skaters have markedly greater circumferences of upper extremities, skinfolds thickness and body fat percentage in regard to the others. The obtained heterogeneities are confirmed by the discriminative factors structures. The demands of powerful takeoffs, sprints and landings in figure skates on the ice in different microclimatic conditions of training make the group of figure skaters different. The demands of their sport early develop muscles of the lower extremities with keeping a large amount of body fat in comparison to other athletes in the group of aesthetic disciplines.
