Background. This study investigated the acute effects of different half–time re–warm ups on vertical jump height during simulated basketball games. Methods. Ten college level males (age (mean ± standard deviation (SD)), 22.0 ± 5.0 years; weight, 86.0 ± 5.5 kg; height, 193 ± 1 cm.) were divided into two teams, who played three simulated basketball games with three different type half-time re-warm ups: aerobic; aerobic + post-activation potentiation exercises and aerobic + post-activation potentiation + stabilization exercises. Counter-movement jump was measured before and during the simulated basketball game at seven time points: before and after warm up, after the 1st, the 2nd quarters, after re-warm up and after the 3rd and the 4th quarters. Simulated basketball games were separated at least by 72 hours. Results. The non-signifcant decrease in Counter-movement jump height during simulated basketball games was observed after executing all three different types of half-time re-warm ups. However, Counter-movement jump signifcantly (p < .05) decreased during simulated basketball game only in aerobic type half-time re-warm up game. Conclusion. During simulated basketball game, the least decrease in Counter-movement jump height was observed after aerobic type re-warm up with post-activation potentiation exercises performed at half-time. Keywords: basketball, half-time re-warm up, power, post activation potentiation.
