تأثير التدريب البليومتري بدلالة بعض المتغيرات البيوميكانيكية لتطوير القوة الانفجارية و زمن أداء بعض مهارات الرمي من أعلى (Nagi Waza)‎ لدى لاعبي الجودو

الملخص EN

The research aims to identify the impact of plyometric training in terms of some biomechanical exercises to develop explosive power and the time of some throwing skills from above (Nagi Waza) among judo players.

the researcher used the experimental approach.

the one-group design on which the pre and marginal measurement was applied, and the study was applied to a sample of (12) players who are enrolled in the egyptian federation for judo sport, and the experiment was applied in the judo hall at the faculty of physical education.

the research sample was selected randomly, and some general civil tests were measured for the development of the constructional strength, which included (the sick wallaby of stability-vertical ranks-carrying on the right foot working on the left foot pushing a medicine ball with two hands from in front of the chest pushing a medicine ball from behind the head pack a medicine ball from behind by spinning).

also, some biomechanical exercises were measured, the skills Ippon Seo Nagi-O Goshi-Osoto Gari) (developed) through 3D imaging (3DM) to infer the skill performance sand of the skills under study.

some skill tests such as the test of cyclonic strength in judo are also measured.

and also considering the speed force with the police, and the researcher designed a study program to develop the commercial force and the time of performance with shooting skills from the top (Nag Waza), and training on it for a period of (16) weeks, with (3) training units of various unit times.

education (120) minutes.

one of the most important results was that the experimental group achieved superiority in live measurements over attic measurements in physical expressions that determine the building strength of the research sample, as well as the experimental group developed a custom in live measurements over tribal measurements in the skill variables under study and also the group's possession the experimental position in the marine corps on the total absence of the biomechanical fruits (the time of skillful performance) the security skills under discussion, and one of the most important recommendations was to direct the trainers to rely mainly on the access of the biometric swarm within the units of the training program during the studio periods of the campaign to develop the commercial time and then improve the time of the performance of the throwing skills in the sport of judo, which leads to the application of the goal of the anti-sports dialogue, and the vector of effort.
