Kinematics of springboard phase in Yurchenco style vault

The object of this study si the kinematics analysis of the center of mass (COM) in the springboard phase of the Yurchenko-style vault performed bye 14 female gymnasts during the 2006 Italian Championship for Clubs. The purpose was to widen the biomechanics knowledge about thi sphase. Temporal, horizontal and vertical spatial, horizontal and vertical velocity and body's angle parameters were estimated. A representative kinematics analysis of the Yourchenko's springboard phase was compiled based on these parameters. The results indicated that the gymnasts use the board to avoid a large decrease in the COM horizontal velocity and increase COM vertical velocity. These were realizing by a great body's angle at the borad impact, reducing the amount of the downward motion in the gathering and maximizing the successive upward lift of the COM.
