Purpose: The purpose of this study was to investigate effects of repetitive different jump pre-conditioning activities on post activity performance enhancement (PAPE). Methods: Twenty-six male sports science faculty students who were physically active between the ages of 18-22 to participate in the study were divided into a squat jump group (SJG) (n= 14, age 20.0 ± 1.3 year, height: 175.1 ± 6.7 cm, body weight: 71.9 ± 6.9 kg) and a countermovement jump group (CMJG) (n= 12, age 20.1 ± .9 year, height: 175.3 ± 7.9 cm, body weight: 71.3 ± 8.2 kg). Squat jump (SJ) and countermovement jump (CMJ) tests were performed before the pre-conditioning activity, 4 min and 10 min after the pre-conditioning activity. SJG performed SJ and CMJG performed CMJ as the pre-conditioning activity with three reps. One-way repeated measures ANOVA was performed to determine the PAPE effect of pre-conditioning activities, SJ and CMJ on the variables flight time (FT), jump height (JH) and power (P) in SJ and CMJ tests after 4 min and 10 min. Significance level was taken as P< .05. Results: Statistically significant differences were found as PAPE effect in SJ test FT, JH and P variables in the SJG at 4 min and 6 min after the pre-conditioning activity SJ (F(2;12)= 10.607; P= .002, η2= .639 for FT; F(2;12)= 9.323; P= .004, η2= .608 for JH and P). In CMJG, there were no statistically significant differences in PAPE effect in the CMJ test FT, JH, and P variables 4 min and 8 min after the pre-conditioning activity CMJ. Conclusions: In conclusion, the time-dependent differences in SJ and CMJ performance of PAPE effects caused by repetitive pre-conditioning activities, SJ and CMJ, showed the importance of determining the exercises that will create a pre-conditioning and optimal rest periods for post-PAPE performance.
