Sažetak
INTRODUCTION: Vertical jump ability is an indicator of lower limb power, important for performance in many sports activities (Caia et al., 2016). Vertical jumping is also an integral element in classical ballet performance (Wyon et al., 2006). Many factors possibly influencing vertical jump height in classical dancers have been previously studied (Wyon et al., 2006). However, the influence of different anthropometric measures has not yet been thoroughly explained. The aim of the study was to investigate the relationship between the selected lower limb anthropometric characteristics and vertical jump height in professional ballet dancers. METHODS: The participants were professional classical ballet dancers, members of the ensemble of the Croatian National Theatre in Zagreb (n=37, 24 females ; age (mean±SD) 31.8±7.8 yrs ; height 170.2±7.5 cm ; body mass 58.6±10.3 kg). Pelvic width, thigh length, lower leg length, foot length, thigh girth, calf girth and Q-angle were measured. Vertical jump ability was tested by Sargent jump test. A multiple regression analysis with vertical jump height as criterion and anthropometric parameters as independent variables was performed using a forward stepwise procedure. RESULTS: The average vertical jump height was 43.6±9.9 cm. The results of the regression analysis indicated four predictors explaining 51% of the variance in vertical jump height (R2=0.51, F(4, 32)=8.22, p<0.0001). The anthropometric characteristics significantly predicting vertical jump ability were foot length (beta=0.33, p=0.028), calf girth (beta=0.66, p=0.001), thigh girth (beta=-0.49, p=0.012), and Q-angle (beta=-0.27, p=0.048). CONCLUSION: Expectedly, foot length was positively related with vertical jump height, but the previously determined relationship between other longitudinal leg dimensions with jump height was not confirmed. While larger lower leg muscle mass, indicated by a larger calf girth, was positively related with jump height, there was a significant negative relationship between thigh girth and jump height, a result discordant with previous studies (Wyon et al., 2006). This result could possibly be attributed to a positive relationship between thigh girth and body fat percentage, previously indicated as a negative predictor of jump height (Caia et al., 2016). Increased Q-angle can be related with both decreased jumping performance and increased risk of knee injuries (Russell, 2013). REFERENCES: Caia et al. (2016). J Strength Cond Res, 30(11), 3073-3083.
