The contractile history of skeletal muscle plays a pivotal role in subsequent performance. Despite the potential performance enhancing effects of PAP, the order of conditioning stimulus has received little attention. The aim of the present study was to examine the effect of ballistic and heavy load exercise order on upper body post-activation potentiation. Eleven male, currently active rugby players, (mean ± SD body mass, 91.5 ± 9.6kg , height 179 ± 2.8 cm) performed a ballistic bench press throw (BBPT) followed by a 5-min rest. The subjects then completed the conditioning stimulus in a randomised order. The two methods used were PLYO/ HEAVY LOAD and HEAVY LOAD /PLYO this was then followed by another BBPT. Maximum distance (Dmax), Rate of Force Development (RFD), peak force (Fpeak ), peak power output (Ppeak ), and peak velocity (Vpeak ) were measured using a linear position transducer. One way ANOVA showed a significant effect in Ppeak and Vpeak (P<0.05), whilst subsequent post-hoc analysis using pairwise comparisons revealed a greater post-BBPT Ppeak and Vpeak following the HL/ PLYO and the PLYO/ HL interventions (P<0.05; Table 1). No significant differences were revealed in Fpeak, Dmax or RFD for any of the conditioning stimuli (P>0.05), and no significant differences existed between the HL/ PLYO and the PLYO/ HL interventions (P>0.05). EMG activity was greater following both conditioning stimuli in the triceps brachii (P<0.05). The present study indicates that plyometric/ heavy load and heavy load/ plyometric augment sporting performance.

Penny, Blake (Cardiff Metropolitan University, 2015)A muscle’s ability to generate force and velocity is determined by several components which are a consequence of its contractile history; however, this has been shown to be acutely yet significantly influenced following ...
Effects of a heavy resistance conditioning activity on post-activation potentiation and subsequent drop jump performance Leach, Joshua (University of Wales Institute Cardiff, 2010)This investigation was conducted to examine the extent to which a low volume heavy resistance conditioning activity could induce post-activation potentiation, and consequently augment the performance of subsequent drop ...
