الملخص EN

The research aims to the research aims to identify the research aims to identify the impact of kinetic rhythm training on some biomechanical variables and the level of tactical performance of junior kumite in karate, the researcher used the experimental approach on a sample of (31) juniors (under 14 years old) at the rose island club in Mansoura, and the best juniors were chosen as a model to compare its biomechanical variables with the rest of the research sample, and (10) juniors who were surveyed, and (20) emerging who were conducted the basic study, were randomly divided into two groups, one experimental and the other control.

the most important results were reaching a set of kinetic rhythm exercises that contribute to improving the level of tactical performance of junior kumite in karate, and kinetic rhythm exercises led to improving the biomechanical variables of junior kumite in karate, with statistically significant differences between the average degrees of dimensional measurement of the experimental and control groups in favor of the dimensional measurement of the experimental group in biomechanical variables and the level of tactical performance of junior kumite in karate.

the most important recommendations were the application of the training program for its positive impact on the biomechanical variables and the level of tactical performance of kumite players in karate, the need for coaches to pay attention to motor rhythm training in training programs at all different age stages because they encourage players to perform at their maximum without feeling stressed, conducting more studies similar to the nature of the current research on kata players in karate, diversity in the use of training methods and methods when applying rhythm exercises to increase the elements of excitement and suspense and competition between players, with the need to start teaching juniors to find the best rhythm suitable for each skill separately in light of some biomechanical variables so that he can integrate skills with each other to develop tactical performance.
