Abstract

The purposes of this study were to identify kinematic variables that govern successful performance and judges' scores and to establish correlative relationships among those variables of Yurchenko layout with a full twist in female vaults. Thirty-two vaults data were collected from national competition by four video cameras (60Hz sampling rate). The obtained scores from judges’ decision were mainly affected by post-flight peak height, horse contact time, knee angle at landing, and horse take-off angle. Modified deterministic model showed that round-off entrance and take-off angles and resultant velocity of the CM were the starting variables affecting performance in following kinematic variables. Knee angle at landing, a highly influential variable on the obtained point, was only determined by judges’ decision without significant relationship with previous kinematic variables.
