THE EFFECT OF PLYOMETRIC STRENGTH TRAINING ON DEVELOPING THE MOST IMPORTANT PHYSICAL ABILITIES, SPIKES PERFORMANCE AND BLOCKS FOR VOLLEYBALL JUNIOR PLAYERS

The volleyball game of sports that rely on the basic skills of offensive and defensive and special skill beating overwhelming and too defensive skills (bulwark), which had been a major development, making it harder than the possibility of scoring points easily and this is something which has given the importance of developing the skills of beating overwhelming and bulwark, and through the experience of the researcher being players for the game of volleyball and up to date most of the teams in the Elite League and even at the level of the team, noted the lack of attention to some of the coaches to prepare your physical exercises physical abilities associated with the performance skills of the junior volleyball, which negatively affects the performance of my skills (beating overwhelming and bulwark) and in turn, the lack of good results, so the researcher felt the use of force exercises to develop the most regressive own physical capacity and its impact on the accuracy and performance of the beating overwhelming bulwark junior volleyball. and target your search: 1 - Preparation of exercises to develop strength pummel the most important physical abilities of junior volleyball players. 2 - see the effect of strength training backlash in the evolution of the most important physical abilities and accuracy performance of the beating and crushing bulwark for beginners volleyball players. The researcher used the experimental design groups Almtkavitan with pre and post tests. And identifies research community my players back line in clubs Babylon l youth, who are (56) players were selected the same way the simple random totaling (30) players, and is then divided into two groups the first experimental rate ( 15) players, and the second officer and by (15) players also. The researcher conducting the experiment exploratory tests and then extract the scientific bases have been processing its data through the use of statistical methods appropriate ones (mean, standard deviation, test (t) for independent samples and symmetric, simple correlation coefficient). Was the most important conclusions are: 1 - The emergence of a positive impact in the evolution of the physical abilities and my skills for the beating overwhelming and bulwark of the experimental group and the control group. 2 - The emergence of a preference for the experimental group in the development of physical abilities for using strength exercises and pummel my skills and beating overwhelming bulwark and all of the tests
