The research aims to study compared in some variables biomechanical and electrical activity - muscle to stage payment in Shot Put with crawl and rotation methods, by identifying some of the variables biomechanic and electrical activ¬ity - muscle to pushing stage in Shot Put manner crawl, to identify some of the variables biomechanic and activity electrophoresis - muscle to stage pushing in Shot Put method rotation, the researcher used the descriptive method was sample player Egypt and the team champion Arabs in Shot Put under 20 years old, has conducted analysis biomechanical and electrical activity - muscle performance art for Shot Put to crawl and rotation method, then the researcher stage pushing in methods to study, and the results showed an increase the number of variables biomechanics un¬der study that increase values in technic rotation more than technique crawl at the beginning, and the middle stage of pushing, and the moment of disposal, D detailed attachment arm push and knee right leg for a moment to get rid of technique crawl more than rotation, Projection velocity Technique largest circulation of crawling, Projection angle 38 degrees in the crawl turnover 41 degrees, in the rotation, The height Projection point in crawling higher turnover, pay less stage time in creep turnover, digital highest level in rotation technique for crawling, increase the values of the electrical activity The contribution rates lower limb muscles under study in technic crawl over rotation, mean values increased electrical activity to the muscles of the upper limb in rotation technique for crawling, smooth performance during the pushing stage rotation technique more than crawling technique. |
