Aouichaoui, C, Trabelsi, Y, Bouhlel, E, Tabka, Z, Dogui, M, Richalet, JP, and Bouchez Buvry, A. The relative contributions of anthropometric variables to vertical jumping ability and leg power in Tunisian children. J Strength Cond Res 26(3): 777-788, 2012-The purpose of this study was to examine the relative contributions of anthropometric variables to vertical jumping ability and leg power and to establish reference values of vertical jumping parameters in athletic Tunisian children aged 7-13 years in both sexes. Three hundred and ninety-one athletic Tunisian children (208 boys and 183 girls) aged 7-13 years were randomly selected to participate in our study. They were asked to perform squat jumps and countermovement jumps. Jump heights and leg power were simultaneously provided by the optojump device. Full and stepwise regression models were calculated to identify which anthropometric parameters significantly contributed to performance variables. The multiple regressions showed that age, weight, standing height and fat-free mass were the predictors of jumping performance. The results may help in verifying the effectiveness of a specific training program and detecting highly talented athletes.
