The most popular method of stretching is static stretching. Vibration may provide a means of enhancing range of motion beyond that of static stretching alone.
This study sought to observe the effects of vibration on static stretching to determine whether vibration-aided static stretching could enhance range of motion acquisition more than static stretching alone in the forward split position.
Ten highly trained male volunteer gymnasts were randomly assigned to experimental (N = 5) and control (N = 5) groups. The test was a forward split with the rear knee flexed to prevent pelvic misalignment. Height of the anterior iliac spine of the pelvis was measured at the lowest split position. Athletes stretched forward and rearward legs to the point of discomfort for 10 s followed by 5 s of rest, repeated four times on each leg and split position (4 min total). The experimental group stretched with the device turned on; the control group stretched with the device turned off. A pretest was followed by an acute phase posttest, then a second posttest measurement was performed following 4 wk of treatment. Difference scores were analyzed.
The acute phase showed dramatic increases in forward split flexibility for both legs (P < 0.05), whereas the long-term test showed a statistically significant increase in range of motion on the right rear leg split only (P < 0.05). Effect sizes indicated large effects in all cases.
This study showed that vibration can be a promising means of increasing range of motion beyond that obtained with static stretching in highly trained male gymnasts.
最流行的拉伸方法是静态拉伸。振动可能提供一种手段，以增强仅通过静态拉伸所达到的活动范围。
本研究旨在观察振动对静态拉伸的影响，以确定在纵劈叉姿势下，振动辅助静态拉伸是否比单纯静态拉伸能更有效地增加活动范围。
十名训练有素的男性志愿者体操运动员被随机分为实验组（N = 5）和对照组（N = 5）。测试为纵劈叉，后膝弯曲以防止骨盆错位。在最低劈叉位置测量骨盆前上棘的高度。运动员将前后腿拉伸至不适点，持续10秒，然后休息5秒，每条腿和每个劈叉位置重复四次（共4分钟）。实验组在设备开启的情况下进行拉伸；对照组在设备关闭的情况下进行拉伸。先进行预测试，然后是急性期后测试，在治疗4周后进行第二次后测试测量。对差异分数进行分析。
急性期时，双腿的纵劈叉灵活性均显著提高（P < 0.05），而长期测试表明，仅右后腿劈叉的活动范围有统计学意义的增加（P < 0.05）。效应量表明在所有情况下均有较大效应。
本研究表明，对于训练有素的男性体操运动员，振动可能是一种比静态拉伸更有前景的增加活动范围的方法。
