Analysis of the rhythm and characteristics of lower limbs moving speed in the backward step gliding shot put putting technique of Asian Champion LI Ling
By basing her study subject on LI Ling,women shot put champion in Doha Asian Games,the author studied the rhythm and characteristics of lower limbs moving speed at different stages in the backward step gliding shot put putting technique of LI Ling,and revealed the following findings:at the step gliding stage,LI Ling’s moving speed of body center of gravity and the shot put was increased significantly,but compared with other excel-lent athletes,the difference between the speed of the center of gravity and the speed of the shot put of LI Ling is too small;at the transition stage,LI Ling maintained a good speed of body center of gravity and the shot put;at the final power exploding stage,LI Ling’s speed of body center of gravity dropped too fast,which produces an adverse effect on final acceleration of the shot put.
