KINEMATICS ANALYSIS OF CHINESE VAULTING HORSE ATHLETE YANG YAHONG'S ACTION OF "HANDSPRING WITH 90&ORDM-180&ORDM-LAYOUT BACK DOUBLE TWIST"

Abstract

"Handspring with 90&ordm-180&ordm-layout back double twists" is the new developed kind of action in the women gymnastics championship in recent years. Yang Yahong is the only one that can complete this action. With the method of sports biomechanics, the kinematics characteristic of her action will be analyzed and her advantage and disadvantage will be exposed. The finding shows that her running up is fast, the angle speed of the handspring in the second flight is swift and the pose in space is excellent. However, the amount of time of pushing horse is over long and the height of the 'handspring in the second flight is not enough.
