Back squats (BSQ) have been shown to effectively potentiate lower body power in a subsequent performance activity. There is a plurality of post activation potentiation (PAP) studies in which the BSQ and vertical jump (VJ) are used. To date, there is little information regarding BSQ and horizontal jump (HJ) performance. Nine collegiate ice hockey players from the California State University, Long Beach ice hockey team volunteered for the study. Participants performed five testing sessions separated by 96 hours. The first testing session was a one repetition maximum (1RM) BSQ to assign the athletes specific intensity. The intensity chosen was 87% of the athletes’ 1RM, which means they should complete five repetitions (87%) for the potentiated testing sessions. The four testing sessions were randomized consisting of a back squat followed by horizontal jump (BSQ-HJ), back squat followed by vertical jump (BSQ-VJ), horizontal jump only (CT-HJ) and vertical jump only (CT-VJ). During the potentiated conditions participants had a rest interval of 5 minutes between the BSQ and VJ or HJ. Alpha-level was set a priori at 0.05. The results indicate that both vertical (p = 0.017) and horizontal (p = 0.003) jump were significantly increased (VJ = +5.51cm, HJ = +11.55cm). The present study helps indicate that muscular power performance can be improved in VJ and HJ using the PAP training phenomenon in collegiate ice hockey players.
