The effect of special exercises in developing the values of some bio kinematics variables and physical abilities of the accuracy of the crushing transmission skill in volleyball (Misan players 20-25 years old)

The importance of research is reflected in the preparation strength exercises according to scientific and objective foundations that contribute improving level technical performance skill overwhelming transmission volleyball by upgrading values bio kinematics physical variables, which ultimately constitute general form thus reach best game volleyball. Reaching higher levels one important matters requires knowledge most mechanical for angles muscular work, mastering relying on kinetic analysis as a logical means phenomenon evaluated objectively determine areas weakness applicants, Missan Governorate. As problem, it lies not using modern training methods develop through process linking side improve motor path skill, led decline volleyball, so use special correct approach It has great benefit because moving towards path, developing physical, mechanical, cognitive aspects alike. identify effect explosive power arms speed characteristic legs some kinematic variables accuracy applicants Missan. researcher’s hypothesis: There are significant differences crushing between control experimental groups favor group. A unit at rate (3) units per week, researcher chose his community deliberate way, they Maysan Governorate 2022/2023 season, numbering (15) players, constitutes (80%) original divided into an group (6)) And (6) players reconnaissance experiment, attempts were given all members sample, photographed US-made mobile device iPhone 11 pro max (240) images second, number (3), RAM 4 GB. also used Kenova program analyze extract variables. concluded: have developed from post-test result similar serve. Field tests procedures abilities explosive, maximum ability, addition conducting experiments other offensive skills same specialized effectiveness.
