الملخص EN

The research aims to identify the statistical modeling of the effectiveness of the skill performance of punches and kicks in terms of anthropometric, physical, and biomechanical indicators for young karate and taekwondo.

the descriptive approach was used through biomechanical kinetic analysis, and the research sample consisted of (27) young women, so that the junior karate (15) and taekwondo juniors (12) performed the skills under research with perfection were selected in a deliberate way from the research community in the clubs of rose island and dialogue in Dakahlia, in the age stage under (14 years).

the shooting was done with a high-frequency camera 240 cadres / sec and analysis using tracer software and the best attempt was chosen for punching and kicking to analyze it and extract anthropometric, physical, and biomechanical indicators, then arrange and classify the data using excel 365 and the data was analyzed statistically using spss vr 25.

the most important conclusions were to reach a statistical modeling design through the equation of multiple linear regression by stepwise regression method between anthropometric, physical and biomechanical indicators and the effectiveness of the skill performance of punching and kicking among young taekwondo and karate as follows : punched taekwondo : skill performance = 0.459 * vertical jump +0.424 * kinetic balance + 0.186 * biomechanical effectiveness +0.112 * punch speed main stage +-0.126 biomechanical force +- 0.027*closing stage time.

punched karate : skill performance = 0.309 * arm length + * 0.367 kinetic balance + 0.234 * agility + -0.191 * training age +0.080 * main stage time + 0.110 * elbow angle + 0.133 * flexibility +-0.109* punch speed main stage + 0.089* mid width.

for kicking taekwondo : skill performance = 0.536 * pelvic angle + 0.474 * kick height relative to player height.

for kicking karate : skill performance = 0.613* pelvic angle + 0.245 * pre-collision velocity +-0.149 * right kick at 10 s.

the most important recommendations were to use the results resulting from the multiple linear regression of anthropometric and physical biomechanical indicators in training programs for athletes to raise the level of skill performance of junior karate and taekwondo.
