Abstract

Post activation potentiation (PAP) is an acute enhancement of muscular function subsequent to an intense muscle conditioning activity. Practical application of PAP as a physical preparation for enhanced performance is a topic of considerable interest in the sport performance community. The purpose of this study was to determine if a dynamic warm-up (WU) plus a progression of deadlift (DL) sets culminating in a one-repetition maximum DL (1-RM DL) (i.e., a PAP conditioning activity) is more effective in improving the standing long jump (SLJ) as opposed to using a dynamic WU alone. Secondarily, it was of interest to determine if there was a meaningful relationship between the 1-RM DL and SLJ ability. Twenty NCAA Division I male North American football players participated in the study (age=20.3±2.3 years, height=183.5±6.3 cm, mass=96.3±17.1 kg). Participants met three times separated by one week. The initial gathering was an orientation meeting where participants were briefed on the study protocol and height, age and body mass were recorded. During the first data collection the participants completed a dynamic WU immediately followed by a progression of DLs culminating in a 1-RM DL; this served as a PAP conditioning activity. Following the PAP WU (5-6 minutes) the participants completed two trials of SLJs separated by 2-3 minutes. During the second data collection the participants completed the dynamic WU only followed (5-6 minutes) by the participants completing two trials of SLJs separated by 2-3 minutes. A paired t-test was used to compare the maximum SLJ between WU conditions and a Pearson correlation coefficient (r) was calculated to compare 1-RM DLs with SLJ scores. The SLJ was significantly greater (4.3±7.5 cm) following the 1-RM DL PAP warm-up (p<0.01). The relationship between the 1-RM DL and SLJ scores was r=0.53 (p<0.01) with a coefficient of determination of CD=0.28. Within the parameters of this study, a dynamic WU that included a 1-RM DL as a PAP conditioning activity significantly improved SLJ performance over a dynamic WU alone. Further, there is a moderate positive relationship between maximum DL performance and SLJ ability.
