摘要
目的:观察深层肌肉刺激仪(DMS)对缓解健康成年人高强度抗阻训练后延迟性肌肉酸痛的疗效。方法:选择2016年6至8月在南方医科大学第三附属医院康复医学科实习及进修人员56例作为研究对象,采用随机数字表法将其分为治疗组28例、对照组28例,试验过程中治疗组脱落4例。两组均通过肱二头肌高强度向心-离心抗阻训练,诱发延迟性肌肉酸痛。在训练后即刻和训练后24 h,治疗组给予DMS干预,对照组给予DMS假干预治疗。在训练前、训练后、即刻干预后、24 h后、24 h干预后分别采用VAS评分、肌骨超声进行评估,观察训练前后不同时间节点的各项观察指标变化情况,对DMS在缓解延迟性肌肉酸痛方面的效果进行评定。结果:即刻干预后,治疗组的VAS评分、RI值均低于对照组,差别有统计学意义(P<0.05);24 h干预后,治疗组的VAS评分却高于对照组,差别有统计学意义(P<0.05),而治疗组的RI值仍低于对照组,差别有统计学意义(P<0.05)。即刻干预后,两组的PSV值无统计学差异(P>0.05),而24 h干预后,治疗组的PSV值高于对照组,差别有统计学意义(P<0.05)。治疗组血流分级随着时间延长,其值出现显著性改变(P<0.001),其血流分级值由大到小排序:干预后、训练后、24 h干预后、24 h后、训练前。对照组血流分级随着时间延长,其值出现显著性改变(P<0.001),其血流分级值由大到小排序:训练后、干预后、24 h干预后、24 h后、训练前。结论:DMS能够缓解高强度抗阻训练后即刻出现的局部肌肉酸痛和肌肉僵硬,而对于DMS作用于训练24 h后出现的延迟性肌肉酸痛则无正面影响,反而会加重肌肉酸痛的程度。
Objective:To investigate the efficacy of deep muscle stimulator(DMS)in relieving delayed-onset muscle soreness(DOMS)after high-intensity resistance training in healthy adults.Methods:Between June and August 2016,56 interns and trainees from Department of Rehabilitation Medicine,Third Affiliated Hospital of Southern Medical University,were enrolled as study subjects,divided into the treatment group(n=28)and the control group(n=28)by random number table.During the study,four subjects in the treatment group dropped out.The both groups underwent biceps high-intensity centripetal-centrifugal resistance training of the biceps brachii to induce DOMS.Immediately and at 24 h after training,the treatment group was given DMS intervention,while the control group received sham DMS intervention.The subjects were evaluated with VAS scores and musculoskeletal ultrasonography before and after training,immediately after intervention,at 24 h after training and at 24 h after intervention,so that the changes in indicators at different time points before and after training were observed,and the efficacy of DMS in relieving DOMS was assessed.Results:Immediate after intervention,the VAS score and RI value were lower in the treatment group than those in the control group,with statistically significant differences(P<0.05).At 24 h after intervention,the VAS score was higher in the treatment group than that in the control group,with statistically significant difference(P<0.05),yet the RI value remained lower in the treatment group compared with the control group,with statistically significant difference(P<0.05).Immediate after intervention,the PSV value did not differ statistically between the two groups(P>0.05);at 24 h after intervention,the PSV value was higher in the treatment group than that in the control group,with statistically significant difference(P<0.05).Over time,the blood flow grading showed significant changes in either group(both P<0.001),and the time points with blood flow grades sorted from high to low in the treatment group were immediately after intervention,immediately after training,24 h after intervention,24 h after training,and before training;those in the control group were immediately after training,immediately after intervention,24 h after intervention,24 h after training,and before training.Conclusion:DMS relieves local muscle soreness and stiffness immediately after high-intensity resistance training,but has no positive effects on delayed-onset muscle soreness that occurs at 24 h after training;on the contrary,it increases muscle soreness at this moment.
