Robinson, J (2011). An investigation to discover whether PAP is exercise specific. High load, low volume muscular contractions preceding explosive activity have been shown to improve performance (PAP). Although the type of explosive activity may effect the performance enhancement capabilities. The purpose of this study was to discover if PAP responses differed between two contrasting explosive activities. 15 male amateur rugby union players (mean ± SD: age 20.59 ± 0.57 years, height 176.0 ± 9.4 cm, body mass 91.4 ± 11.0 kg) performed a 3RM back squat, followed by a single clean pull (100% 1RM of power clean) at 15 seconds and 4-minute intervals up to 24 minutes. All participants then returned several days later to perform a 3RM back squat, followed by a mid-thigh clean pull (100% 1RM of power clean) from blocks at 15 seconds and 4 minute intervals up to 24 minutes. Peak power (PPO), mean power (MPO) and rate of force development (RFD) were measured using the Ballistic Measurement System (BMS). No significant differences (p<0.05) were recorded between PAP (improvement in performance) and activity (CHP & CHP-B). Significant differences (p<0.05) were found between performance variables (PPO, MPO & RFD) and activity (CHP & CHP-B). Although PAP may not be exercise specific within the CHP and CHP-B it is possible that some exercises are able to elicit PAP better than others.

How is repeated sprint performance affected by different intensities of recovery? Active vs Passive Tanner, Sam (Cardiff Metropolitan University, 2013)The purpose of this study was to compare the effects of different intensities of recovery on subsequent repeated sprint performance. Nine males who regularly participate in sport performed 6 six second sprints, interspersed ...
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 ...
