Özet
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-PAPwould induce greater potentiation for 40-yard dash than SQ-PAPwhereas SQ-PAPwould 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-PAPloading session and HT-PAPloading session with 48 hours interval with a randomized open crossover study design. BLsession was also accepted as control and familiarization session. SQ-PAPand HT-PAPexercises 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 PAPloading exercise. RESULTS: Statistical analysis revealed that the potentiation effects of SQ-PAPand HT-PAPexercises 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-PAPexercises can be used interchangeably and safely to avoid training monotony during longer training periods for chronic adaptations.
