BACKGROUND: This study aimed to determine and compare the post-activation potentiation (PAP) effects of the Back Squat (SQ-PAP) and Hip Thrust (HT-PAP) exercises in terms of vertical jump height (VJ), 20-yard dash and 40-yard dash time in physically active university students. Considering the Force-vector theory, it was hypothesized that HT-PAP would induce greater potentiation for 40 yard dash than SQ-PAP whereas SQ-PAP would induce greater potentiation for 20-yard dash and VJ than HT-PAP.
METHODS: Seventeen kinesiology and exercise science students (8 male and 9 female) who resistance train at least 3 times/week (age, 21.71± 1.49 years; body mass, 75.58± 11.89 kg; height,173.98± 11.88 cm and training experience 5.47±2.00 years) joined this study. They performed three experimental sessions namely; Baseline (BL), SQ-PAP loading session and HT-PAP loading session with 48 hours interval with a randomized open crossover study design. BL session was also accepted as control and familiarization session. SQ-PAP and HT-PAP exercises were performed roughly at 90 % of 1 Repetition maximum (1 RM) of the subjects with three repetitions. Subjects were tested for vertical jump height (VJ), 20-yard dash and 40- yard dash time before and 8 minutes after each PAP loading exercise.
RESULTS: Statistical analysis revealed that the potentiation effects of SQ-PAP and HT-PAP exercises on VJ height, 20-yard and 40-yard dash were similar that none of the loading exercises with 8 min rest interval had any increasing or detrimental performance effect on VJ (p=0.923), 20-yard dash (p=0.133) as well 40-yard dash time (p=0.570).
CONCLUSIONS: These findings demonstrate that none of the loading protocols with above mentioned exercises have any detrimental or improving effects on VJ height, 20-yard dash and 40-yard dash time for physically active university students who joined this study. Although no acute potentiation effect has been found, this study also shows that SQ-PAP, HT-PAP exercises can be used interchangeably and safely to avoid training monotony during longer training periods for chronic adaptations.
