Comparative analysis of support response forces in basketball players of differ- ent skill level during motor actions

Abstract

Support response forces in young basketball players have been analyzed during motor action execution. Objective. To determine peculiarities of support response forces during motor action execution by basketball players of different skill level. Меthods. Analysis of scientific and methodological literature, method of expert assessment, pedagogical testing, dynamometry, methods of mathematical statistics. Results. The method of expert assessment revealed informative tests for basketball players of different qualifications, which allows to determine the degree of foot loading, namely: standing jump up with double take-off, upward-forward jump with one foot running take-off, stop by a step, stop by a jump. Pedagogical testing was conducted to assess the load on the athlete’s foot. To do this, we selected the elements of the basketball technique, which received the hig­ hest score in the course of the examination. Quantitative indices of the maximum force of the support reaction during taking-off and landing, force impulse were obtained. Besides, quantitative data of the vertical component of strength indices during standing jump up with double take-off were obtained. In the course of analyzing the upward-forward jump with one foot running take-off, stop by a step, stop by a jump quantitative data of the resul­ ting strength indices and their horizontal and vertical components were received. It was found that the load on the feet of young basketball players is high and reaches almost 3500 H while performing individual moves. There was also a tendency to increase the load on the foot at the next stages of long-term training, as evidenced by much higher indices of strength interactions between the support and the foot of skilled basketball players
