The Effects of VertiMax Training on Vertical Jump Height through the Phenomenon of Post-Activation Potentiation

The current study looked to see if a resistance jumping device, called a VertiMax, could be an effective means of inducing the pre-training phenomenon known as post-activation potentiation (PAP). A 2 testing session protocol was used for this study with at least 48 hours separating the 2 testing sessions. 10 participants, (4 recreationally trained and 6 collegiate level athletes) were recruited to participate in this study. The first testing session was used to measure the participants’ vertical jump height without the VertiMax. The second training session was used to introduce the VertiMax training device (the PAP stimulus) before performing another vertical jump test. Comparison of the pre- and post-intervention statistics revealed there was not a significant difference between the pre- and post- interventions (p > 0.05). The results suggest that the VertiMax training protocol utilized for this current study was not an effective pre training stimulus to induce a PAP effect on vertical jump height.
