الملخص EN

The purpose of this study aims to research improving the water entry distance in the starting skill by using plyometric exercises in terms of biomechanical indicators for junior swimmers 50 meters freestyle hat is through : Identifying the effect of plyometric exercises, biomic parameters, and general information on developing harmonic abilities.

Recognizing the effect of plyometric exercises in developing the level of digital achievement among swimming juniors, the research sample .

Identifying the percentages of the progress of the physical variables indicative of the harmonic abilities and the level of digital achievement among the junior swimmers, the research sample.

The researcher used the experimental method due to its relevance to the nature of the research, The sample of the research was chosen by the intentional method, which numbered (20) students specializing in swimming training, The proposed program was implemented by (1) unit per week by (8) daily training unit during the application period, After completing the application of the program under study, the dimensional measurements of the research sample were carried out, the data was processed statistically, and the results were presented and discussed.

The most important results were the determination of the kinematic variables and the harmonic abilities of the stages of performance of the skill of starting free swimming, as well as the degree of impact of plyometric exercises on the harmonic abilities and the level of achievement of the skill of starting free swimming.
