The effect of anthropological characteristics on the efficiency of execution of forward kick

A sample of eighty-two karatists at the ages from ten to fourteen has been analyzed for a system of 25 variables (12 morphological, 12 basic motoric variables and 1 specific motoric variable) with the aim of establishing the effect of prediction system of morphological variables and a system of basic motoric variables on the criterion variable, i.e., the direct forward kick - mae geri. The obtained results showed that the system of morphological variables had a statistically significant effect on the execution of direct forward kick. Among the individual variables in the regression analysis body weight had the largest effect. The stepwise method showed that body height and weight had highest prediction values. Young karatists of high body height, with long extremities and increased weight, had better results in the execution of direct forward kick. The investigation of basic motoric variables used in the regression and stepwise analyses indicated that the endurance in half-squat with weight and standing jump had statistically significant effects on the efficiency of direct forward kick. Thus it was concluded that the speed of forward kick depends on the explosive and static strength of legs
