服装压对瑜伽运动中女子上身肌肉疲劳的影响

Influence of fitting yoga clothing pressure on the upper body comfort of women

为研究瑜伽运动过程中贴体瑜伽服装压对女子上身肌肉疲劳的影响,以60名热爱瑜伽运动且体型符合160/84A号型区间的在校女大学生为实验对象,测量其穿着不同尺寸的3件样衣在瑜伽运动中上身肌肉的服装压和表面肌电值,采用表面肌电值与主观感受值的显著相关性分析和多重比较检验对实验数据进行分析。结果表明:表面肌电4项指标与瑜伽运动中上身肌肉的疲劳有显著相关性,可以作为瑜伽运动中上身肌肉疲劳程度的评价指标;斜方肌和背阔肌对疲劳反应比胸大肌和腹外斜肌明显;服装压对上身肌肉疲劳的影响主要集中在瑜伽运动的中后期;中等程度的服装压能够有效缓解瑜伽运动中上身肌肉的疲劳,低等和高等程度的服装压均不能缓解瑜伽运动的上身肌肉疲劳,甚至会加重上身肌肉疲劳。

In order to study the influence of body-fitting yoga clothing pressure on the fatigue of women′s upper body muscles during yoga exercise,60 female college students who love yoga and have a body shape conform to the 160/84A size range were selected as the experimental subjects.Measurements were made of 3 female college students wearing different sizes.The clothing pressure and surface EMG of the upper body muscles of each sample garment in yoga exercises were analyzed using the significant correlation analysis between the surface EMG value and the subjective perception value and the multiple comparison test to analyze the experimental data.The results show that the four indicators of surface EMG are significantly related to the fatigue of upper body muscles in yoga exercises,and can be used as evaluation indicators of upper body muscle fatigue in yoga exercises;the trapezius and latissimus dorsi muscles respond to fatigue more than the pectoralis major and abdominal external oblique muscles are obvious;the influence of clothing pressure on upper body muscle fatigue is mainly concentrated in the middle and late stages of yoga;moderate clothing pressure can effectively relieve the fatigue of upper body muscles in yoga,and low and high degrees of clothing pressure cannot alleviate the upper body muscle fatigue of yoga exercise,can even aggravate the upper body muscle fatigue.
