Body Physique and Composition in Premenarchal Ballerinas and Female Athletes in Aesthetic Sports

Ballet, rhythmic gymnastics, and figure are disciplines that are begun early in childhood an pose high demands on the performers´ functional and energy capacities, which may influence the development of the body, s physique and composition. This study investigated whether differences in the body, s physique and composition were preexistent in young premenerchal ballerinas and female athletes in aeshtetic sport disciplines before training was started. Twenty-four anthropometric measurements were made of body physique and composition, and body mass index (BMI) and fat percentage were calculated. The groups of premenarchal dancers and athletes did not differ significantly in body height, body mass, or BMI. They also showed similarities in skeletal measurements, with the exception of ankle diameter. In measurements sensitive to specific training loads significant differences were found, most notably in figure skaters, who had markedly greater arm circumferences than did ballerinas and rhythmic gymnasts. Ballerinas and rhytmic gymnasts did not have significant differences in soft tissues measurements, with the exeption of thecalf skinfold thickness, which was significantly greater in ballerinas. Skinfold thickness and body fat persentage were higher in skaters than in rhythmic gymnasts and ballerinas. Young ballerinas and rhythmic gymnasts were more slender with lower skinfold values and limb circumferences than skaters.
