Introducció: L’objectiu d’aquest estudi fou avaluar la capacitat de salt, el pes corporal i la talla d’estudiants de l’escola de dansa clàssica del Teatro Colón de Buenos Aires.

Material i mètodes: Cinquanta estudiants femenines (10 a 21 anys) i 16 masculins (10 a 26 anys). Variables: estatura (m), pes (kg), índex de massa corporal, alçada (cm) del salt sense contramoviment (SJ), del salt amb contramoviment (CMJ), índex d’elasticitat (IE) (%).

Resultats: Pes baix el 38% de les dones i el 6,3% dels homes. A les dones se’ls aplicà el test t per a grups independents segons categories d’edat, entre categories d’estat nutricional, per als salts SJ, CMJ, IE, sense diferències significatives. Es realitzà un ANOVA d’una via entre categories d’edat per a l’SJ, CMJ, IE, sense diferències significatives per a l’SJ (F = 0,8; p = 0,46), CMJ (F = 0,28; p = 0,76), IE (F = 0,61; p = 0,55). En els homes la prova ANOVA d’una via entre categories d’edat mostrà significació en l’SJ (F = 9,97; p = 0,002) i el CMJ (F = 17,58; p = 0,00). Hi hagué diferències entre la categoria 1 amb la 2 i la 3, que tendiren a agrupar-se (test post hoc de Scheffé, p < 0,05). IE: test de Kruskal-Wallis, sense diferències significatives entre categories d’edat (χ2 = 2,17; p = 0,34). Qualitat del salt: 68% dels homes i 42% de les dones assoliren un IE ≥ 6%, cosa que indica bona relació CMJ/SJ.

Conclusions: Es suggereixen controls de salut atès l’elevat nombre de ballarines de baix pes. Pel que fa al salt, el grup de dones en podria millorar la capacitat.

Introduction: The 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 methods: The 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) (%).

Results: Underweight 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 = .8; p = .46), CMJ (F = .28; p = .76), IE (F = .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 (χ2 = 2.17; p = .34). Quality jump: 68% of males and 42% of females achieved an IE of 6%, indicating good CMJ/SJ ratio.

Conclusions: Health checks are suggested, given the high number of underweight dancers. As regards the jump, the female group could improve its capacity.
