AIM: The present study was designed to compare the effects of post activation potentiation (PAP) protocols on explosive activities of trained young athletes.
METHODS: Twenty-six young team sport players (handball, n = 12; basketball, n = 14; age 15.4 ± 0.3 years; height 169.5 ± 6.4 cm; weight 61.4 ± 7.6 kg; Tanner stages 3 and 4) performed seven countermovement jumps (CMJ) and seven 20 m sprints at baseline, ~15 s, 4, 8, 16, 24 and 30 min after three different stimulus conditions: 3 sets of 10 repetitions of double-leg drop jumps (PAPD), 3 sets of 5 repetitions of alternate-one-leg drop jumps (PAPO), or walking control (CON).
RESULTS: A significant reduction in explosive performance was observed at each time-point in both groups. Negative PAP effect occurred on the 20 m sprint in PAPO at 16 (P = 0.008), 24 (P = 0.001) and 30 min (P < 0.001) and in PAPD at 30 min (P = 0.002) compared to CON.
CONCLUSION: This study indicated the negative effect of PAP on subsequent explosive performance in young team sport players. These findings represent a practical suggestion for the prudent use of PAP protocols aimed at enhancing vertical and horizontal explosive performances of young athletes.
