POST-ACTIVATION POTENTIATION DOES NOT WORK WITH FOOTBALL PLAYERS
Conley, D. S., Molacek, D. R., Meier, M. T., McIntyre, A. C., & Evetovich, T. K. (2013). Post-activation potentiation has varying effects on vertical jump performance in collegiate football players. Medicine & Science in Sports & Exercise, 45(5), Supplement abstract number 2463.
This study examined the effects of 3 RM parallel back half-squats on vertical jump performance in collegiate football players (N = 11). Ss included running and defensive backs, and wide receivers. Ss were randomly assigned to two warm-up protocols featuring: i) control which consisted of cycling five minutes at 25 W, five minutes rest, and a vertical-jump test and 2) post-activation potentiation which consisted of cycling five minutes at 25 W, five minutes of rest, eight repetitions of parallel back half-squats at 50% 1 RM, two minutes rest, 3 RM parallel back half-squats, eight minutes of rest, and a vertical-jump test. The best of three vertical-jump scores with one minute seated rest between attempts was evaluated using a Vertec vertical jump measurement device.
There was no difference in vertical jump performance when the protocol performances were compared.
Implication. Unlike published work showing 3 RM parallel back half-squats improved sprinting performance, this study did not indicate similar effects with football players.
