SUMMARY:

Exercise-induced muscle damage (DMIE) occurs when the individual performs unusual or very intense physical activities, being characterized by loss of strength and range of motion, delayed muscle soreness, swelling and increased creatine kinase concentrations, which can generate performance reduction. Among the techniques used to reduce the effects of muscle damage, blood flow restriction (BFR) has been used both before DMIE, as ischemic preconditioning (IPC), and after. However, the effects of BFR in the attenuation of muscle damage are still controversial in the literature, with studies showing improvements in the attenuation of the damage and in the recovery process, while others demonstrate that there is no difference compared to the control or the sham group. Objective: The objective of this review was to systematically analyze the evidence on the effects of passive blood flow restriction performed before or after exercise in the attenuation of muscle damage. Methods: This systematic review was conducted in accordance with the PRISMA recommendations. Two researchers independently and blindly searched the electronic databases: National Library of Medicine (PubMed), Scopus, Web of Science, SPORTdicus, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, Pedro and Clinicaltrias.gov. Randomized clinical trials, published in English until January 2021, with samples composed by humans and that evaluated the effects of passive blood flow restriction performed before or after exercise on DMIE measurements. The risk of bias assessment was performed using the RoB2 tool. Results: After reading titles, abstracts and full texts, a total of 12 papers (4 papers using the RFS before DMIE and 8 with use after) published between 2012 to 2021 were eligible for this review, comprising 221 individuals (213 men and 8 women). Delayed muscle soreness, perceived exertion and perceived recovery and serum creatine kinase levels were the most used variables to measure DMIE. The damage protocols were quite varied, as were the variables used to verify the effects of the RFS on the DMIE and the protocols used in the RFS and sham. In addition, most studies had methodological quality with some concerns, indicating that the studies had considerable methodological bias. Conclusion: The studies present many methodological differences, especially the type of exercise used in the damage, DMIE markers and protocols used to apply the RFS, some showing that the RFS can be an effective technique to mitigate the DMIE, while others show no difference of RFS compared to control or sham. It is suggested that new articles be made on the subject using better methodological qualities and protocols to generate DMIE with greater damage magnitudes.
