Evaluación de la capacidad de salto y estado ponderal en estudiantes de danza clásica de la escuela del Teatro Colón en Buenos Aires

Abstract

IntroductionThe aim of the study was to assess the jumping ability, body weight and height in classical dance students of the Teatro Colón school in Buenos Aires. Material and methodsThe study included 50 female (10-21 years) and 16 male (10-26 years) students. Variables: height (m), weight (kg), body mass index, height (cm) of squat jump (SJ) and countermovement jump (CMJ), elasticity index (IE) (%). ResultsUnderweight was found in 38% of females and 6.3% of males. In females, t-test for independent groups was implemented according to age categories between categories of nutritional status for SJ, CMJ, IE, with no significant differences. One-way ANOVA was implemented between age categories for SJ, CMJ, IE, with no significant differences for SJ (F=0.8; p=.46), CMJ (F=0.28; p=.76), IE (F=0.61; p=.55). In the males one-way ANOVA test between age categories, SJ showed significance (F=9.97; p=.002) and CMJ (F=17.58; p=.00). Difference was between category 1 with 2 and 3, which tended to cluster (Scheffe post hoc test, p<.05). IE: Kruskal-Wallis test, showed no significant differences between age groups (X2=2.17; p=.34). Quality jump: 68% of males and 42% of females achieved an IE of 6%, indicating good CMJ/SJ ratio. ConclusionsHealth checks are suggested, given the high number of underweight dancers. As regards the jump, the female group could improve its capacity.
