Effect of Post Activation Potentiation Exercises on Women Elite Gymnasts’ Vaulting Run-up

Objective:The purpose of this study is to determine the effect of static stretching followed by PAP stimulation in different periods on elite female gymnasts, and the relationship between countermovement jump (CMJ) and vaulting run-up kinematics after PAP stimulation over time. Methods:Five national gymnasts volunteered were recruited in this work. Using a single set of multiple pre-and post-test methods. SPSS 21.0 were used to analyse the data. P value was set at 0.05. Results:1) As compared to baseline, hips ROM shown improved and lasted the entire 16 mins duration after static stretching induced. 2) CMJ peak force were increased significantly between 4-12 mins with peak value at 8 mins;3) last-3-step (L3S) , last-2-step (L2S) and final step (FS) of vaulting run-up showed reduction of speed, only L2S indicated PAP were effective between 8-16 mins with 8 mins peak value post PAP. Conclusion:The experimental protocol of this study can effectively induce the PAP effect of the experimental subjects and is reflected by the hips ROM, CMJ peak force and the last-2-step speed of vaulting run-up.
