Abstract

This study determined whether a post-activation potentiation (PAP) effect could be elicited across multiple sets of a contrast PAP protocol. Fourteen rugby league players performed a contrast PAP protocol comprising for sets of two paused box squats accommodated with bands alternated with two standing broad jumps. The rest period between the squats and the jumps and between the sets was 90s. A control protocol with standing broad jumps only was performed on a separate session. A standing broad jump was performed ~2 min before each protocol and served as a baseline measurement. Standing board jump distance was significantly greater (4.0 ± 3.4% to 5.7 ± 4.7%) than baseline during the four sets of the contrast PAP protocol with the changes being medium in the 1st, 2nd and 4th sets (effects size [ES]: 0.58, 0.67 and 0.69, respectively) and large for the 3rd set (ES: 0.81). Conversely, no PAP effect was observed in the control protocol. Additionally, the stronger players displayed a larger PAP effect during each of the four sets of the contrast PAP protocol (Cohen's d: 0.28 - 1.68) and a larger mean effect across these four sets (Cohen's d: 1.29). Horizontal jump performance is potentiated after only 90 s of the rest following an accommodating exercise and this PAP effect can be elicited across four sets. Additionally, the PAP response is largely mediated by the individual's strength level. These results are of great importance for coaches seeking to incorporate PAP complexes involving horizontal jumps in the their training programs.
