The effects of post-activation performance enhancement and different warm-up protocols on swim start performance

This study aimed to examine the efects of post- activation performance enhancement (PAPE) on swim start performance and lower body power performance after diferent warm-up protocols. Ten male national-level swimmers performed three diferent warm-ups: (i) a swim-specifc warm-up (SW, control protocol) ; (ii) PAPE (an experimental protocol) ; and (iii) SW followed by PAPE (SW+PAPE, an experimental protocol). PAPE consisted of performing three series of 5 drop jumps. A repeatedmeasures ANOVA showed signifcant diferences between the protocols in the swim start performance (F = 8.89 ; P< 0.001) and countermovement jump (F = 2.22 ; P= 0.047). SW+PAPE induced greater improvements in swim start time to 15 m (ES= − 0.47, P= 0.017) and entry time (ES= − 1.83, P< 0.001), the countermovement jump reactive strength index modifed (ES= − 1.83, P< 0.001), eccentric rate of force development (ES= 0.69, P= 0.047), and index of explosive strength (ES= 0.94, P= 0.005) compared to SW. The current fndings of this study indicate that the drop jump PAPE protocol, in addition to SW, is an efective tool because it could improve athletes’ capacity for a more efcient swim start and their countermovement jump performance. Furthermore, the results of this study indicate that PAPE induced by drop jumps could be time-efcient and practically applicable in facilities with limited resources.
