Terzis, G, Karampatsos, G, Kyriazis, T, Kavouras, SA, and Georgiadis, G. Acute effects of countermovement jumping and sprinting on shot put performance. J Strength Cond Res 26(3): 684-690, 2012-The purpose of this study was to investigate the acute effects of countermovement jumping and sprinting on shot put performance in experienced shot putters. Ten shot putters (best performance 13.16-20.36 m) participated in the study. After a standard warm-up including jogging, stretching, and 4-6 submaximal puts, they performed 3 shot put attempts with maximum effort, separated with 1.5-minute interval. Three minutes later, they performed 3 maximal consecutive countermovement jumps (CMJs). Immediately after jumping, they performed 3 shot put attempts with maximum effort, separated with a 1.5-minute interval. One week later, they carried out a similar protocol, at similar external conditions, but they performed a bout of 20-m sprinting instead of the CMJs, to potentiate shot put performance. Muscular strength (1 repetition maximum in squat, snatch, bench press, incline bench press) and body composition (dual x-ray absorptiometry) were measured during the same training period (+/- 10 days from the jumping and sprinting protocols). Shot put performance was significantly increased after the CMJs (15.45 +/- 2.36 vs. 15.85 +/- 2.41 m, p = 0.0003). Similarly, shot put performance was significantly increased after sprinting (15.34 +/- 2.41 vs. 15.90 +/- 2.46 m, p = 0.0007). The increase in performance after sprinting was significantly higher compared with the increase after jumping (2.64 +/- 1.59 vs. 3.74 +/- 1.88%, p = 0.02). In conclusion, the results of this study indicate that a standard warm-up protocol followed by 3 maximal bouts of shot put and either 3 consecutive countermovement jumps or a bout of 20-m sprinting induce an acute increase in shot put performance in experienced shot putters.
