The preparation of players is similar to what is happening and occurs in the game according to correct biochemical indicators that help in developing technical performance, which in turn can improve the motor and planning performance by special exercises according to what is consistent with the physical, skill and motor capabilities of the players, and that interest in directing exercises with a special goal to develop some physical capabilities The skills of defending the stadium and receiving the transmitter according to correct scientific foundations for the technical performance of the skills contribute well that the skill performance is very close to idealism through biochemical indicators, Hence the importance of research with the enemies of special exercises for some physical capabilities of the skill to defend the stadium and the effect of these exercises in developing some biochemical indicators for young players in volleyball as a contribution from us to raise the level through technical analysis of performance, while the goals of the research are to prepare special exercises to develop some physical capabilities and defense skill On the field, and to identify the differences between the pre and post tests of some physical and skill capabilities and the values of biochemical variables for the experimental and control groups and between the experimental and control groups, the researcher used the experimental approach, either The research sample is understanding the youth players of South Gas Club in volleyball for ages (17-19 years) for the football season 2019-2020, The researchers touched on the exercises, especially for the prepared approach, the tests used, and the method of imaging, as the sample was imaged with a Chinese-made video camera (Casio) with a speed of (240 p / s).

The analysis was done by applying the Kinovea program, and the data were statistically treated using the SPSS 23 program.

), After discussing the results, the most important conclusions were reached, which are intensive training and special physical abilities of specific skills, which contributes to an improvement towards the ideal performance in terms of skills and biochemical mechanics.
