The aim of this study was to examine whether acute whole-body vibration, a single bout of drop jumps, or a combination of both may enhance countermovement jump (CMJ) and would affect volitional pace 3 km running performance. Twelve healthy and recreationally active males completed 4 conditions in randomized order: (i) 5 sets of 30 s calf raises on the platform but without vibration; (ii) 5 sets of 30 s calf raises on the vibration platform with 30 s rest intervals between sets; (iii) 5 sets of 6 drop jump with a 30 s rest interval between sets; (iv) 5 sets of 30 s calf raises on the vibration platform followed by 6 drop jumps with a 30 s rest interval between sets. Before, 3-min after, and immediately after a 3 km run each participant performed CMJ. No significant difference between conditions (p = 0.327) for the 3 km time trial was found. Whereas CMJ height and relative peak power were significantly improved in post-3 km run than at baseline (p < 0.001 and p = 0.025) and post-warm-up (p = 0.001 and p = 0.002) in all conditions. The present study indicates that warm-up consisting of either whole-body vibration, drop jumps, or a combination of both failed to acutely improve CMJ and 3 km volitional pace running performance in physically active males. However, the increase in the CMJ performance was noted after the end of the 3 km run, which may indicate that the warm-up protocols used were insufficient to enhance subsequent performance.
本研究旨在探讨急性全身振动、单次跳深或两者结合是否可以增强纵跳（CMJ），并影响 3km 跑步的自主节奏。12 名健康且有规律运动的男性以随机顺序完成了 4 种条件：（i）在平台上进行 5 组 30 秒的小腿抬高，但没有振动；（ii）在振动平台上进行 5 组 30 秒的小腿抬高，每组之间休息 30 秒；（iii）5 组 6 次跳深，每组之间休息 30 秒；（iv）在振动平台上进行 5 组 30 秒的小腿抬高，然后进行 6 次跳深，每组之间休息 30 秒。在 3km 跑步前、后 3 分钟和后立即进行 CMJ。3km 计时赛中，各条件之间无显著差异（p=0.327）。然而，在所有条件下，3km 跑后的 CMJ 高度和相对峰值功率均明显高于基线（p<0.001 和 p=0.025）和热身后（p=0.001 和 p=0.002）。本研究表明，在有规律运动的男性中，全身振动、跳深或两者结合的热身均不能急性提高 CMJ 和 3km 自主节奏跑步表现。然而，在 3km 跑结束后，CMJ 表现有所提高，这可能表明使用的热身方案不足以提高后续表现。
