Application Of The Post-Activation-potentiation Effect For Developing Power And Agility

[Purpose] The aim of this study was to determine the acute effect temporal of a post activation potentiation training protocol on counter movement jump(CMJ)and agility performance.A secondary objective was to evaluate the physical functioning of subjects.[Methods] sixty trained adults were the subjects of this study.The variables measured were times in counter movement jump,average power and agility performance.The intervention session with post activation potentiation training consisted of counter movement jump with 3 minute,10 minute,15 minute,20 minute,25 minute,30 minute rests.The intervention session were: 1.no conditioning contraction protocol;2.1 sets of 3 repetitions at 90% 1RM;3.1 sets of 3 repetitions at 90% 1RM + 6 second maximum frequency contractions;and,4.1 sets of 3 repetitions at 90% 1RM + 7 sets of 6 second maximum frequency contractions.For the statistical analysis repeated measures of SPSS was used,and for the student's t-test was used.[Results] Times in counter movement jump and agility performance showed a significant induction between the control set and the three experimental sets,but the average power and integral electromyography(IEMG)of maximum voluntary contractions(MVC),did not show significant changes.[Conclusion] The results of the study show the acute and a prolonged positive effect of post activation potentiation training,over time,in counter movement jump and agility performance by adults.This effect is due to the post activation potentiation of the lower limbs' muscles in the counter movement jump and agility performance.
