Description
Summary:BACKGROUND: Post-Activation Performance enhancement methods have been previously studied to potentiate power and plyometric exercises. The purpose of this study were to determine if 1) Heart Rate Percentage (HR%) can be used as an intra-set rest modulator during a post-activation potentiation enhancement (PAPE) training method to improve vertical jump performance, and 2) if there is a relationship between heart rate variability (HRV), and lower body strength, and responses to PAPE as observed in lower body electromyography and vertical jump performance. METHODS: Fourteen resistance-trained subjects participated in this blocked randomized crossover study. Two experimental PAPE conditions were performed: 1) PAPETime and 2) PAPE-HR%. Each condition included 5 series of 5 repetitions of the back squat, performed at 87% of the individual's 1RM followed by 1-minute rest between the squats and vertical jump and 3 minutes rest between series in the PAPE-Time. In the PAPE-HR% experimental condition, the rest between the squat and the vertical jump was individualized to 50% of the individual's predicted heart rate maximum. RESULTS: The ANOVA repeated measures analysis indicated that vertical jump performance measures between baseline measures and PAPE conditions were significantly different. For PAPE-Time, vertical jump performance increased by 8.1%, and for PAPE-HR%, by 8.4%, with improvements in vertical jump performing showing nonsignificant differences between these conditions. Additionally, there was no association between HRV and vertical jump performance, or lower body strength. CONCLUSIONS: Using time and heart rate percentage as an intra-set modulator during PAPE exercises may be a viable option to increase vertical jump height.
