A kinematic analysis of the Tsuhakara3/1 in Yang Hak Seon and Feng Zhe's vault

摘要

Kinematic characteristics and vault features of Tsuhakara3/1 were studied to provide theoretical basis for vault training. Methods: The images of Tsuhakara3/1 in Yang Hak Seon and Feng Zhe's Vault Finals of Asian Games in 2010 were analyzed to get relevant kinematic data. Results and Conclusions: The horizontal velocity of Feng Zhe was higher while touching the board than Yang Hak Seon's and the loss of horizontal velocity after stepping on to the springboard was less than Yang Hak Seon's. The first flight time of Yang Hak Seon was longer than Feng Zhe while his supporting time was shorter than Feng Zhe, pushing the vaulting horse swiftly and powerfully; however, Feng Zhe supported the vaulting horse more positively than Yang Hak Seon's, he swung legs by a larger margin, and his position of leaving from the vaulting horse was closer to vertical position than Yang Hak Seon's. The height and the distance of second flight for Feng Zhe were larger than Yang Hak Seon's, but his body was twisted more slowly, and the body was being twisted while landing; however, Yang Hak Seon finished twisting before landing, his ability of landing and controlling posture were better than Feng Zhe. Feng Zhe twisted his body slowly during second flight and the body was being twisted while landing, which mainly caused the second place.
