IMPULSE PRODUCTION OF DOMINANT AND NON-DOMINANT LIMBS OF YOUNG SOCCER PLAYERS

Abstract

The aim of this study was to compare the impulse production between the dominant and non-dominant limb of soccer players during countermovement jumps on a double force platform. A bilateral difference of more than 15% was considered as significant. Therefore a nonparametric contingency test between dominant or non-dominant limbs and the existance of lateral differences, and a paired t-test were performed. No significant differences were found for impulse production between dominant and non-dominant limbs (p=0,067). However, for 15 of the 36 individuals (41%) a more than 15% greater momentum production was found for the dominant than for the non-dominant limb. For identification of individual bilateral differences, countermovement jumps on a double force platform seem to be an adequate method.
