背景:证据表明,限制血流的有氧训练对治疗纤维肌痛有益。这项研究评估了可行性,安全,以及对纤维肌痛妇女进行血流限制的有氧训练计划的效果。
方法:纳入了37例纤维肌痛患者,13名平均年龄为59±3岁,BMI为26±3岁,接受多种药物治疗的人开始了干预期。干预组使用放置在股直肌上部的闭塞带进行血流限制的有氧运动,限制的总持续时间为14分钟,分为两个7分钟的时间段,休息期为3分钟,总疗程为17分钟。使用视觉疼痛量表(VAS)测量压力强度,10分中的7分(n=7)。非干预组同期进行不限制血流量的有氧运动,休息时间,和会话的总持续时间(n=6)。干预包括每周2次,有氧步行之间72小时,共9周。使用感知劳力量表(RPE)的等级分别测量步行,强度在10分中的6至7分之间。VAS和RPE量表的视觉和口头支持始终在研究者的监督下提供。使用测试评估功能能力(六分钟步行测试,递增穿梭行走测试,通过测力计进行膝盖伸展和手握测试,30s椅子支架测试,和定时上行测试)。使用问卷评估症状学(广泛疼痛指数,症状严重程度评分,纤维肌痛影响问卷,和多维疲劳清单),并收集血液样本。
结果:没有不良反应,干预组只有一名参与者退出.组间和组内差异表明,干预组在功能测试方面有所改善;CSTp=0.005;6MWTp=0.011;手柄p=0.002;根据问卷调查,TUGTp=0.002,疾病影响降低;FIQ刚度p=0.027。两组的生化结果均在正常范围内。
结论:限制血流的有氧训练可能是可行的,安全,作为改善心肺健康的体育锻炼处方工具,比不受限制的有氧训练更有效,力量,balance,和僵硬的女性纤维肌痛。
BACKGROUND: Evidence suggests that aerobic training with blood flow restriction is beneficial for treating fibromyalgia. This study evaluated the feasibility, safety, and effects of an aerobic training program with blood flow restriction for women with fibromyalgia.
METHODS: Thirty-seven women with fibromyalgia were included, and thirteen with an average age of 59 ± 3, a BMI of 26 ± 3, and who were polymedicated started the intervention period. The intervention group performed aerobic exercise with blood flow restriction using occlusive bands placed in the upper part of the rectus femoris, with a total duration of 14 min of restriction divided into two periods of 7 min with a rest period of 3 min and a total session duration of 17 min. Pressure intensity was measured using the visual pain scale (VAS), scoring 7 out of 10 (n = 7). The non-intervention group performed aerobic exercise without restriction of blood flow for the same periods, rest periods, and total duration of the session (n = 6). The intervention included 2 weekly sessions with 72 h between aerobic walking for 9 weeks. Walking was measured individually using the rating of perceived exertion scale (RPE) with an intensity between 6 and 7 out of 10. Visual and verbal support for the VAS and RPE scale was always provided throughout the sessions supervised by the investigator. Functional capacity was assessed using tests (six-minute walk test, incremental shuttle walk test, knee extension and handgrip test by dynamometer, 30 s chair stand test, and timed up-and-go test). Symptomatology was assessed using questionnaires (Widespread Pain Index, Symptom Severity Score, Fibromyalgia Impact Questionnaire, and Multidimensional Fatigue Inventory), and blood samples were collected.
RESULTS: There were no adverse effects, and only one participant in the intervention group withdrew. Between-group and intragroup differences showed that the intervention group obtained improvements in the functional tests; CST p = 0.005; 6MWT p = 0.011; Handgrip p = 0.002; TUGT p = 0.002 with reduced impact of the disease according to the questionnaires; FIQ Stiffness p = 0.027 compared with the nonintervention group. Biochemical results remained within normal ranges in both groups.
CONCLUSIONS: Blood flow-restricted aerobic training may be feasible, safe, and more effective than unrestricted aerobic training as a physical exercise prescription tool to improve cardiorespiratory fitness, strength, balance, and stiffness in women with fibromyalgia.
