低强度激光对运动肌肉劳损的治疗研究

Study on the treatment of exercise muscle strain by low intensity laser

低强度激光在治疗运动肌肉劳损方面取得显著成效,以运动员为实验对象测试低强度激光治疗运动肌肉劳损的效果。随机选取54名运动员划分为安静对照组、运动对照组、激光治疗组,激光治疗组详细分为45 J/cm^2、30 J/cm^2、15 J/cm^2三种激光剂量组;采用激光波长621.7 nm,低强度氦氖激光照射运动员,采用SPSS18.0软件对指标数据进行统计分析。与对照组数据对比发现,低强度激光可有效缓解肌肉炎症、降低细胞损伤数量,使结蛋白的光密度均值和积分光密度显著回到正常水平,同时减轻运动肌肉劳损程度,降低CK值、LDH值水平,其中45 J/cm^2剂量激光治疗运动肌肉劳损效果显著。

Low intensity laser has achieved remarkable results in the treatment of sports muscle strain.Athletes are set as experimental subjects to test the effect of low intensity laser in the treatment of sports muscle strain.Fifty-four athletes are randomly selected and divided into quiet control group,exercise control group and laser treatment group.Laser treatment group is divided into 45 J/cm^2,30 J/cm^2 and 15 J/cm^2 laser dosage groups in details.Athletes are irradiated with low intensity He-Ne laser at 621.7 nm,and the index data are analyzed by SPSS18.0 software.Compared with the control group,low intensity laser can effectively alleviate muscle inflammation,reduce the number of cell damage,significantly return the mean and integral optical density of desmin to normal level,and reduce the degrees of muscle strain,CK and LDH.Among them,45 J/cm^2 laser has a significant effect on muscle strain.
