IMPACT OF THE COLLISION AND PUSH ANGLES ON THE PHASES HOP, STEP AND JUMP IN THE TRIPLE JUMP AND THEIR RELATIONSHIP TO THE STAGE OF TAKE-OFF
The purposes of this study were to revealing correlation between the angles of body in the motor performance and stages take-off (time of phase & push angle) in each phases (hop, step and jump) for elite Algerian in triple jump. Our study based on the kinematic analyzes of the phases triple jump in the collision and push stages, through the Kinovea programmer. For this study, we have chosen the analysis of correlation (the Pearson correlation āRā) in each of the phases (hop, step and jump) in the collision and push stages. Based on the practices and weaknesses of elites in practice; we confirm: 1) there is a statistically significant the correlation in the collision stage (hop phase; the angle of trunkĀ°) with the time and angle of push, 2) the problem of our elites is in the hop phase, and its relationship with; the step and jump phases, 3) Improve achieve horizontal vertical velocity in hop phase and preservation in next phases (step and jump) as solution.Ā Article visualizations
Sporting events among the disabled between excellence and ideal in motor performance
The identification of mechanical variables in the motor performance trajectory has a prominent role in improving skill performance, error-exceeding, it contributes seriously to solving some problems of learning and training. The study Aims to highlight the indicators of motor performance for Paralympic athletes during the practicing sports between modelling and between excellences in motor performance, this by taking into account the distinction of athlete practicing with special behavioural skills for the Paralympic athletes. In the study we relied on the analysis of some previous research of biomechanical performance indicators during some of the events sports (shooting activities in the Paralympic athletics, shooting skill in the wheelchair basketball). The results of the study highlight the distinction of disabled practitioners of sporting events identified in motor performance during practice, by overcoming some physics indicators in human movement, as a lower centre of body weight, Increase in offset distance, such resistance which requires them to redouble their efforts. However, the results of the study highlighted the strength of the correlation between biomechanical variables of motor performance and the digital level achievement similar to the other practitioners normal
