The Compairson Of Rotational-shot-put’s And Back-gliding-shot-put’s Technique Characteirstic

Shot put throwing technique has been developing during one hundred years of practice,and has been formed to back gliding shot put and rotational shot put in the two main technicalskills. As the movement level further develop and improve, rotational shot put technique moreand more show its advanced and great potential, since1970s the advent of the technology,constantly refresh a shot put world record, up to now push the lead ball world record forAmerican player R· Barnes in1990to rotate the pusher shot put technology to create23.12meters occupied. Rotational shot put technique has been more and more coaches athletescognitive, use and master, and has gradually become the shot put throwing a kind of trend ofdevelopment.In the light of the world sports development of shot put this situation, the shot movementtraining and the competition status, there is only backward technology in our country. In somelarge domestic game rarely seen by rotational shot put technique of athletes in sports,technology lags behind the world advanced level, for as soon as possible to improve our men’s shot put throwing item scores and shorten the gap between advanced level in the world, andkeep the women’s shot put the existing dominant position is very bad. Therefore, this researchattempts to use kinematic principle, the backward technology and rotating ball technologyevery8results in20.50-23.12meters world class athletes technical video, using softwareDartfish to its technical action video screenshot, analysis of measured data obtained; usesports biomechanics analysis and simulation experiment method, based on the the pair of backgliding shot put and rotational shot put technique characteristics, to holding technology, intothe rotary phase transition technology, finally pushing beyond the equipment posturecomparison, finally forced technical, and must maintain the body’s balance, on the differentphases of the technical aspects of characteristics were compared, and analysis demonstrationof rotating shot put technology superiority, aims to study on the rotational shot put techniquehas a more clear and accurate cognition, clarify some studies and professional sports teachingmaterial of rotary ball techniques of cognitive errors; fill of this technology in the study of thetheory of some blank; for rotational shot put movement technical training to provide some value and a scientific and reasonable theory basis, for better popularization and master.Rotating shot put technology to lay a solid foundation, through the improvement of YouthFoundation of athletic training level and athletic performance, so in a relatively short periodshortening of we and world level shot gap.
