Do the drop jumps provide a post-activation potential?

The aim of this study was to investigate the use of drop jumps (DJ) to promote post-activation potential (PAP) and to improve the performance of vertical jump (VJ). For that purpose 15 Volleyball male athletes (19,88±1,54 years old), were conducted randomly: (I) a countermovement jump control (CCMJ)...

Summary:The aim of this study was to investigate the use of drop jumps (DJ) to promote post-activation potential (PAP) and to improve the performance of vertical jump (VJ). For that purpose 15 Volleyball male athletes (19,88±1,54 years old), were conducted randomly: (I) a countermovement jump control (CCMJ); (II) 6 sets of DJ, followed by 4 minutes of passive rest and 3 CMJ (PDJ); (III) 5RM Smith Machine squat (SMS), followed by 4 minutes of passive recovery, and then 3 CMJ (PSMS). All activities had an interval of 72 hours between them. Jump height and power were measured with a jump platform. It was observed a significant increase in jump height (P<0,001) between PSMS and PDJ, concerning CCMJ. Significant higher values of in jump height (p <0.001) and power (p <0.001) were also observed for PSMS concerning PDJ. It can be concluded that both interventions (PDJ and PSMS) promoted a PAP that influenced the height of the CMJ. The uses of DJ in training and pre-competitive situations seem to be an effective way to improve performance.
