الملخص EN

The research aimed to design a training program using cluster training for junior gymnasts under (11) years old and knowing its effect on muscle stress indicators (beta-endorphin - lactic acid - dehydrogenase) and the performance level of some somersaults (front somersault on the hands - side somersault on the hands with a quarter turn - Back somersault on the hands) on the floor movement apparatus for gymnastics juniors under (11) years old, and the researcher used the experimental method on a sample of (11) junior gymnasts under (11) years old, and among the research tools: assessing the performance level of some somersaults on the floor movements apparatus in gymnastics Biochemical measurements - Training program using cluster training.

Among the most important results: 1- The cluster training program has a positive and significant effect at the level of 0.05 on muscle fatigue indicators (beta-endorphin - lactic acid - dehydrogenase enzyme) for gymnastics juniors under (11) years old.

2- The cluster training program has a positive, significant effect at the level of 0.05 on the performance level of some somersaults (front somersault on the hands - side somersault on the hands with a quarter of a turn - back somersault on the hands) on the floor movement apparatus for junior gymnasts under (11) years old.

3- There are percentages of improvement in the dimensional and tribal measurement of the members of the basic research sample in the indicators of muscle fatigue, with a percentage ranging between (6.04% - 10.31%).

4- There are percentages of improvement in the dimensional measurement from the tribal members of the basic research sample in the level of performance of some somersaults on the floor movement apparatus in the gymnastics under discussion with a percentage ranging between (12.57% - 19.46%).
