The effect of post-activation potentiation on the roundhouse kick in martial arts
AbstractAcute enhancement of the contractile properties of skeletal muscle has been observed during explosive movements following heavy resistance exercise (HRE) and explosively loaded exercise (ELE). It is undetermined whether this phenomenon, termed post-activation potentiation (PAP), can augment the kinetic profile of the roundhouse kick (RHK). This investigation aimed to determine whether RHK force and power could be enhanced if preceded by HRE or ELE. Nine resistance trained, competitive martial artists (mean ± SD: age, 22.8 ± 3.1 years; stature, 1.77 ± 0.03 m; body mass, 73.7 ± 8.2 kg) performed 3 RHKs at 6 times (baseline, post-2, 4, 8, 12 and 16 minutes) under 3 conditions (control, HRE and ELE). The initial control condition contained no intervention. The latter HRE, 3 repetition maximum back squat, and ELE, 2 x 5 drop jump (DJ), conditions were performed in a counterbalanced order. Peak force (Fpeak), peak power (Ppeak), average force (Faverage) and average power (Paverage) were analysed. No significant differences from baseline were revealed at any time, in any condition (p > 0.05). Effect sizes revealed a possibly positive effect on Fpeak from 4 to 16, Ppeak at 4, Faverage and Paverage at 4 and 8 minutes (0.13 – 0.25) following ELE, Ppeak at 12 minutes (0.12) following HRE and Faverage at 8 and Paverage at 2 and 8 minutes (0.13 - 0.19) in the control condition. A significant enhancement of RHK force and power was not achieved via PAP. Competitive martial artists would unlikely benefit from a PAP protocol for this purpose.
