On The Left Side Of The Four Women's Shot Put Athletes Kinematics And Dynamics Analysis

Nowadays, back gliding shot put technique is adopted by most of athletes. Therefore, there are a lot of researches about it in home and abroad . But most of them are two-dimensional or qualitative analysis. With the improvement of research method, three-dimensional analysis is increasing . However it is difficult to reveal the fact which how lower limbs and throwing arm enforce power . In this paper , we adopted method of three-dimensional photograph ,three-dimensional-testing force platform and digital shot put to study the techniques of our province's female shot putter in the experimental condition, in which we combined the kinematics and dynamics to study their techniques and have the left technique as a main research point. In the research, we found that the movement of left limbs is the premise of the whole throwing technique. Moreover ,dynamics research found that the capability of the eccentric and concentric contraction has an effect on the achievement. And as the same time ,the testing force of the digital shot put found that we should emphasize the movenfent of the upwords enforce power of the technique so as to enhance the flying length of the apparatus. We adopted it to explore new scientific methods and make a contribute to our province's athletic train of female shot put.
