Introduction: Post-activation potentiation (PPA) is a phenomenon which improves plyometric performance such as jumps and sprints, through previously applied stimulus by conditioning activity with similar biomechanics. Objective: This study aimed to assess the recovery interval for a specific intensity and population based on PAP on vertical jump height. Methods: Twelve resistance-trained men randomly completed experimental trials with a 48-hour interval between sessions. First, all the participants performed a standard warm-up. Subsequently, performed 6RM squat and then performed one of the three intervals (2 (P2), 4 (P4) and 8 (P8) minutes, to perform the vertical jump. A repeated-measures ANOVA design was used to compare three different PAP protocols. Cohen's effect size (ES) was used to determine the magnitude of the results. Results: Meaningful differences were found between P2 and P8 (p=0.008). The magnitude revealed a small difference on jump height between P2xP4 (ES=0.45) and P2xP8 (ES=0.59) and trivial between P4xP8 (ES=0.18). Conclusion: For the studied population and intensity, 8 minutes is the optimal interval to improve vertical jump height performance. In addition, the stronger participants can exhibit a greater PAP effect.
