Effect of Different Post-Activation Potentiation Intensities on Vertical Jump Performance in University Volleyball Players.

The aim of this study was to analyze the effect of different intensities of PAP on vertical jump performance in university volleyball players. Twelve players performed anthropometric tests, 1 RM (repetition maximum) test in the squatting exercise, and familiarization with the vertical jump test. In subsequent weeks, the subjects underwent 5 more collection sessions with a 24-hr rest interval between them. Prior to each Counter Movement Jump (CMJ) test, the subjects performed an experimental condition: (a) Control; (b) PAP 91% 1RM; (c) PAP 85% 1RM; (d) PAP 70% 1RM; and (e) PAP 60% 1RM. The results showed that the Group submitted to the PAP protocol showed a significant difference in comparison to the Control Group, with higher PAP intensities of 91%, 85%, and 70% of 1 RM verified while the 60% intensity of 1RM showed no significant difference in comparison to the Control Group. The findings indicate that the PAP positively affects the performance of vertical jump in university volleyball players. [ABSTRACT FROM AUTHOR]
