  • This study examined the acute effects of different parallel squat postactivation potentiation protocols with and without whole body vibration on jumping performance in college athletes. Fifteen men (20.3 ± 1.3 years, 179.50 ± 5.3 cm, 81.0 ± 10.8 kg) performed 3 repetitions of a countermovement jump (CMJ) and best drop jump after 3 conditions: (a) parallel squat with 80% 1 repetition maximum without vibration (NV-PS), (b) parallel squat with 80% 1 repetition maximum on a whole body vibration platform (WBV-PS) (1.963-mm amplitude and 40 Hz), and (c) control (C). Each condition was performed under both low-volume (LV) (1 set of 3 repetitions) and high-volume (HV) (3 sets of 3 repetitions) protocols that were followed by both 1- and 4-minute rest periods. Significant improvements were observed for the CMJ height (p = 0.005) after 4 minutes of recovery and the LV protocol (p = 0.015) regardless of the condition. Additionally, for the WBV-PS condition, a significantly lower drop jump height was observed after 1 minute (p = 0.0022) after both low (p = 0.022) and HV (0.010) protocols. In conclusion, 4 minutes of recovery was adequate for improving CMJ height after an LV protocol regardless of the condition and restoring drop jump height performance after WBV-PS regardless of the protocol in male college athletes.
