摘要
为研究骑行运动中骑行裤产生的服装压力对人体肌肉疲劳的影响,以11名骑行爱好者为实验对象,受试者穿着不同号型样衣,借助服装压力测试系统和全无线表面肌电测试系统,分别采集在骑行过程中穿着不同程度紧身骑行裤下肢主要肌肉部位的服装压力值和表面肌电信号,对主观体力感觉等级(RPE)值和客观时域指标均方根振幅(RMS)、频域指标的中位频率(MF)进行相关性分析,对服装压力和肌电指标进行方差分析。结果表明:表面肌电时域指标RMS和频域指标MF与受试者主观疲劳感有一定的相关性,且2个指标的相关性有差异;RMS、MF均可作为生物力学角度评价肌肉疲劳的重要指标;高服装压力可减少肌肉能量损耗,对肌肉疲劳有一定的缓解作用,尤其在骑行运动中后期较为明显;服装压力对不同部位肌肉的影响存在差异,对大腿外侧和内侧的肌肉影响较为明显,对臀大肌无明显影响。
In order to study the influence of clothing pressure on the body fatigue caused by cycling pants during cycling, 11 riders were used as experimental subjects, subjects worn clothing samples of different sizes, the clothing pressure test system and the full wireless surface emg test system were adopted to collect the clothing pressure values and surface emg signal of the main muscle parts of the lower limbs of the tight-fitting trousers during the cycling, correlation analysis was performed on the rating of perceived exertion(RPE) values, the objective indicators root mean square(RMS) and median frequency(MF), and variance analysis was performed on the clothing pressure and the emg index. The results show that the surface emg time domain index RMS and the frequency domain index MF have a certain correlation with the subjective fatigue, and the correlation between the two indexes is different. RMS and MF can be used as important indicators for the fatigue evaluation of muscles in a biomechanical view. High clothing pressure can reduce the muscle energy loss, and has a certain relief effect on the muscle fatigue, especially in the middle and late stages of the cycling exercise. The influence of clothing pressure on different parts of the muscle varies, the outside of the thigh and the inner muscles are significantly affected, and no significant effect exists on musculus glutaeus maximus.
