[Purpose] To investigate the effect of the five animals (wuqinxi) exercises on the lumbosacral multifidus. [Subjects and Methods] This study enrolled two groups of volunteers, 15 volunteers who did the five animals exercises, the experimental group, and 15 volunteers who did aerobic exercise (walking), the control group. Both before and after the 1 year exercise intervention, the average surface electromyography (ASEMG) of the two groups in the process of flexion and extension was recorded and analyzed using DASYLab10.0 software, and the flexion extension ratio (FER) was calculated. [Results] The ASEMG in the process of flexion was lower than the ASEMG in the process of extension both before and after the 1 year exercise intervention on both sides of all volunteers. There was no significant difference in FER between the experimental group and control group before the 1 year exercise intervention; however, the FER of experimental group was lower than that of the control group after the 1 year exercise intervention. There was no significant difference between the two sides in any individual both before and after the 1 year exercise intervention in both groups. [Conclusion] The "wuqinxi" exercises improved the function of the lumbosacral multifidus, and might be an alternative method of reducing low back pain.
[目的] 探讨五禽戏对腰骶多裂肌的影响。[对象与方法] 本研究招募了两组志愿者,15名进行五禽戏锻炼的志愿者作为实验组,15名进行有氧运动(步行)的志愿者作为对照组。在为期1年的运动干预前后,使用DASYLab10.0软件记录并分析两组在屈伸过程中的平均表面肌电图(ASEMG),并计算屈伸比(FER)。[结果] 在所有志愿者两侧,1年运动干预前后,屈伸过程中的ASEMG均低于伸展过程中的ASEMG。实验组与对照组在1年运动干预前FER无显著差异;然而,1年运动干预后实验组的FER低于对照组。两组在1年运动干预前后,任何个体两侧均无显著差异。[结论] 五禽戏锻炼改善了腰骶多裂肌的功能,可能是减轻腰痛的一种替代方法。
