【摘要】 目的探讨建立以脉图指标为主的慢性运动性疲劳的评价方法。方法通过对15名运动员进行持续4个月的强化训练,建立慢性运动疲劳模型;检测疲劳前后脉图、血液和尿液生化指标、反应时、心率变异性(HRV)等的变化,以期对慢性运动性疲劳进行评价。结果慢性运动疲劳后脉率加快(P<0.05)、降中峡h4抬高(P<0.05)、w/t增大(P<0.01),脉图主波变宽大,降中峡抬高并前移,脉象变弦;皮质醇、血红蛋白明显升高(P<0.01),尿pH下降(P<0.05);反应时显著延长(P<0.01);心率变异性中TV、LF/HF呈增大趋势。结论慢性运动疲劳后脉图变化以主波宽大、降中峡抬高并前移为主要特征,可以将脉图作为慢性运动性疲劳的评价方法之一。更多还原

【Abstract】 Objective To establish a method of evaluating sphygmohram of chronic motion fatigue. Methods Fifteen women athletes of college students were trained to make chronic motion fatigue by continuous four-month exercises; the sphygmogram, laboratory indexes, reaction time and heart rate variability(HRV) were measured before and after motion fatigue to assess the chronic motion fatigue. Results In chronic motion fatigue, heart rate was higher (P<0.05), h4 of sphygmogram elevated(P<0.05), w/t rose(P<0.01), the primary wave widened and descending wave rose and forward, and the pulse became taut; the cortisol and hemoglobin increased(P<0.01); urine pH fell(P<0.05); reaction time extended(P<0.01); total variability(TV) and LF/HF tended to increase. Conclusion Chronic motion fatigue is characterized by widened wave and rising-forward descending wave of sphygmogram, which can be used to evaluate chronic motion fatigue.更多还原
