الملخص EN

The research aimed to identify the effect of using cluster training on the performance level of some defensive skills (defensive interview - wall of defense - defensive moves) and biochemical variables (beta-endorphin - lactic acid - dehydrogenase enzyme) among female handball players, born (2006), and the researcher used the experimental approach On a sample of (10) junior handball players, born (2006), and among the research tools: skill tests - biochemical measurements - training program using cluster training.

Among the most important results: The cluster training program has a positive, statistically significant effect at the level of 0.05 on the level of defensive skills performance (defensive interview - blocking wall- defensive moves) for female handball players, born (2006).

The cluster training program has a positive, statistically significant effect at the level of 0.05 on the biochemical variables (beta endorphin - lactic acid - dehydrogenase enzyme) for female handball players, born (2006).

There are percentages of improvement in the dimensional measurement of tribal members of the basic research sample in the level of performance of defensive skills in handball with a percentage ranging between (24.00% - 75.00%).

There are percentages of improvement in the dimensional and tribal measurement of the members of the basic research sample in the biochemical variables with a percentage ranging between (8.86% - 12.66%).

Among the most important recommendations: Using cluster training because of its great effectiveness in improving the concentration of biochemical variables and the level of defensive skills performance of female handball players, born (2006).
