Does Football Player Position and Number of Sets Influence Response to Post-Activation Performance Enhancement?
Abstract
Post-activation potentiation enhancement (PAPE) describes the acute increases in explosiveness (e.g., jump power) from pre-loading muscles with high loads in an exercise of similar biomechanics (e.g., squat). Player position and repetitive sets may affect PAPE response. The purpose of this study was to determine the influence of position and time on power during a PAPE session. Twenty-nine football players training for the NFL draft representing three position groups, Big, Big-skill, and Skill performed two baseline jumps then four alternating trials of squatting-jumping. Jumps were performed on uniaxial dual force platforms and variables for jump height (JH), peak power, and reactive strength (RS) were calculated using ForceDecks software. We used 3 x 5 mixed-design ANOVAs to evaluate the interaction between position and trials on power, p<0.05. There were no significant interactions between group and trial for JH (F(5.09,66.16)=1.20, p=0.319) peak power (F(5.43,70.58)=1.11, p=0.365), or reactive strength (F(5.17,67.18)=1.05, p=0.399). For JH, there were significant main effects for group (F(2,26)=4.72, p=0.18) and trial (F(2.55,66.16)=4.75, p=0.007). For peak power, there were significant main effects for group (F(2,26)=4.89, p=0.16) and trial (F(2.72,70.58)=6.13, p=.001). For RS, there was a significant main effect for trial (F(2.58, 67.18)=14.10, p<0.001, but not for group (F(2,26)=2.27, p=0.123). JH, peak power, and RS were not influenced by the interaction of player position and trial. Skill players jumped higher and expressed greater power than Big-skill and Big. JH, peak power, and RS increased across trials for all groups. Skill players appear to benefit more from PAPE training than Big-Skill and Big players.
