摘要
选择5名女性大学生作为实验对象,测量其穿着紧身裤装跑步时裤装压力与大腿的表面肌电信号(surface electromyography,s EMG)。选用均方根振幅(Root Mean Square,RMS)作为s EMG的分析指标,使用EMGworks Analysis软件提取肌电数据,用SPSS软件进行配对T检验和单因素方差检验分析。研究发现:肌肉疲劳主要发生在跑步运动的中后期,适当的裤装压力可抑制肌肉疲劳,而无裤装压力或过大裤装压力对肌肉疲劳无抑制作用,甚至会诱发肌肉疲劳的产生。抑制肌肉疲劳的服装压力范围为:股直肌1. 98~3. 23 k Pa,股外侧肌2. 07 k Pa,股内侧肌2. 33 k Pa,股二头肌1. 94~2. 30 k Pa。研究结果为女性选择合适的锦纶/氨纶80/20跑步裤装提供了参考,当裤装大腿围度减少2 cm时,裤装压力增大1. 02~1. 41 k Pa。
To explore the impact of trousers stress on female thigh fatigue during running,five female undergraduates were selected as subjects and their thigh trousers pressure and s EMG(surface electromyography)were measured during running in running pants with different press.RMS(Root Mean Square)was used as the analysis indicator of myoelectric signals.EMG data were extracted by use of EMGworks Analysis software.The paired T test and one-way ANOVA test were performed using SPSS.It was found that muscle fatigue mainly occurs in the middle and late period of running;proper trousers pressure can inhibit muscle fatigue;no pants pressure or excessive pants pressure has no effect on inhibiting muscle fatigue,and even may induce muscle fatigue.The clothing pressure range for inhibiting muscle fatigue was 1.89-3.23 kPa for the rectus femoris muscle,2.07 kPa for the vastus lateralis muscle,2.33 kPa for the medial femoral muscle,and 1.94-2.30 k Pa for the biceps femoris muscle.The results showed that the pant pressure increased 1.02-1.41 kPa,when the thigh circumference was reduced by 2 cm,which provided a recommendation to women running enthusiasts when they were choosing 80%nylon and 20%spandex blended running pants.
