Abstract

Background: Blood flow restriction (BFR) exercise has been used to induce skeletal muscle and aerobic adaptations that are similar to those induced by high intensity training, but with less time and lower intensities. The lower time demand and exercise intensity appear advantageous, especially for older people but there may be risks associated with a potential impairment of vascular function after BFR trainings. Therefore, the purpose of this systematic review was to evaluate the effects of aerobic and resistance exercise with BFR on vascular function in the elderly. Methods: PubMed, Embase, Scopus, Lilacs, Web of science, Pedro, Google Scholar and the Cochrane library were searched for articles published until January 2019. This review included randomized and non-randomized controlled trials of BFR exercise for ≥ 4 weeks in older humans. Results: In the first step, 133 articles were identified, of which 22 articles met the inclusion criteria. Sixteen studies were excluded because of the short training period (< 4 weeks) or the average age of participants (< 60 years). Six articles were included in this review (n = 146 individuals, mean age = 69 years old, 71,46% women and 28,54% men). BFR combined with aerobic exercise (n = 2) enhanced arterial and venous compliance in healthy elders and resistance exercises (n = 4) demonstrated no significant effects on vascular function in healthy elders compared to exercise without BFR. Conclusion: These results suggest that the addition of BFR to exercise does even improve vascular function in healthy elderly people. This is a first indication that superimposing BFR is safe also in sedentary elders. However, future research, especially in sedentary elders, is necessary to assess the safety of this method. *Correspondence to: Luciana Diniz Nagem Janot de Matos, Hospital Israelita Albert Einstein, Avenida Albert Einstein 627/701, Jardim Leonor CEP: 05652-900 São Paulo, SP – Brazil, Tel. +55 11 2151-1444, E-mail: lucianajanot@einstein.br

限制血流运动对老年人血管功能的影响:系统综述

背景:血流量限制(BFR)运动已被用于诱导骨骼肌和有氧适应，与高强度训练相似，但时间更短，强度更低。较低的时间需求和运动强度似乎是有利的，特别是对于老年人，但可能存在与BFR训练后血管功能潜在损害相关的风险。因此，本系统综述的目的是评估有氧和阻力运动结合BFR对老年人血管功能的影响。方法:检索PubMed、Embase、Scopus、Lilacs、Web of science、Pedro、谷歌Scholar和Cochrane图书馆在2019年1月之前发表的文章。本综述包括老年人BFR运动≥4周的随机和非随机对照试验。结果:第一步共筛选到133篇文献，其中22篇符合纳入标准。16项研究因训练时间短(< 4周)或参与者的平均年龄(< 60岁)而被排除。本综述纳入6篇文章(n = 146人，平均年龄= 69岁，女性71.46%，男性28.54%)。与不进行BFR运动相比，BFR联合有氧运动(n = 2)增强了健康老年人的动脉和静脉顺应性，阻力运动(n = 4)对健康老年人的血管功能没有显著影响。结论:这些结果表明，在运动中加入BFR甚至可以改善健康老年人的血管功能。这是第一个表明，在久坐的老年人中，叠加BFR也是安全的。然而，未来的研究，特别是在久坐的老年人中，有必要评估这种方法的安全性。*通讯:Luciana Diniz Nagem Janot de Matos，以色列阿尔伯特·爱因斯坦医院，阿尔伯特·爱因斯坦大道627/701,Jardim Leonor CEP: 056552 -900 s o Paulo, SP - Brazil, Tel +55 11 2151-1444, E-mail: lucianajanot@einstein.br
