The purpose of this study was to investigate changes in kinematical parameters for vault approaches through the intervention of sprint training and the instantaneous feedback of run-up kinematical information. Eight male gymnasts training for the 2002 Asian Games served as participants. The gymnasts participqted in sprint training for 20 minutes five times a week over six weeks. The Laser Distance Measurement 300C system (100Hz) was used to record and analyze the full process of vault approach kinematics data about the performance of handspring/salto vault (HS) and the gymnast’s highest value performance (HV). Velocity information was feedback instantly to the participants after every measurement. The kinematical data, four times in total, was analyzed by repeated measures one-way ANOVA and honestly significant difference with an alpha level of .05. The results showed that the peak velocity for the approach of HV performance was significantly increased after sprint training (p<.O5, η2=.717, from 8.54 ( O.37m/s to 8.89 ( O.22m/s), and the peak velocity was significantly closer in to horse from 4.07 ( 1.11 m to 2.59 ( 0.65m (p<.05, r; η2=.562). The changes of kinematical parameters through sprint training not only enhanced the approach velocity and performance quality, but also affected related movements for example the front/salto in the floor exerase Furthermore, the sprint training program had positive effects for warming up.
