Title: Velocity rhythm of shot putting technique of back gliding by LI Mei-ju
Abstract: With the method of biomechanics,it researches into the velocity rhythm of shot putting by Li Mei-ju,Chinese elite woman shot-putter.It is concluded that at the gliding stage,LI Mei-ju's top speed of swing legs appear at the movement right legs stretches positively,while there exists the swing legs vertical speed too high and the enlarging angel of body gravity,which reduces the speed of body gravity and shot;At the transitional stage,right leg of Li Meiju rapidly yield ability and yield change ability of restraining is weakness.The transitional time is longer,velocity of body gravity and shot gravity descend;At the final movement stage,the supporting point of Li Meiju is prominent,and the speed-up effect is striking.
