摘　　要：目的利用表面肌电图评价针刺缓解腓肠肌疲劳的效果。方法 20名男性健康志愿者负重直立提踵,疲劳发生后对腓肠肌局部(承筋穴)针刺15 min(针刺组);4周后进行第二次测试,疲劳发生后休息15 min(非针刺组)。记录不同状态下表面肌电信号和心率。结果两组运动后腓肠肌表面肌电值与运动前相比升高(P<0.05),针刺组针刺后降低(P<0.05),休息组休息后升高(P<0.05)。两组运动后心率明显升高(P<0.05),针刺/休息后较运动后减慢(P<0.05),降低量无显著性差异(P>0.05)。结论针刺可以缓解肌肉疲劳。Objective To explore the effect of acupuncture on gastrocnemius fatigue.Methods 20 healthy volunteers were selected.According to the rating of perceived exercise（RPE） table,when exercise-induced fatigue occurred,the volunteers were needled in Point Chengjin for 15 minutes（acupuncture group）.4 weeks later,they just rest after exercise-induced fatigue occurred for the second time for 15 minutes（non-acupuncture group）.The data of surface electromyographic signal（sEMG） and heart rate were collected.Results The value of low frequency/high frequency（LF/HF） of sEMG of both groups was higher after exercise.The acupuncture group decreased after acupuncture（P0.05）,the non-acupuncture group increased after rest（P0.05）.The heart rate of both groups increased significantly after exercise（P0.01）,and decreased after acupuncture and rest（P0.05）,and there was no significant difference in the decrement between 2 groups（P 0.05）.Conclusion Acupuncture can relieve gastrocnemius fatigue.
