| Resumo: | INTRODUCTION: Blood Flow Restriction (RFS) training is a predominantly low-load
resistance exercise modality, being widely used in several clinical trials, which have as
outcomes the strength and trophism of the upper limbs, but with a limited amount of
systematic reviews that work on summing up their results. OBJECTIVE: To carry out
a systematic review taking into account the muscle strength and trophism outcomes in
RFS training in upper limbs of individuals with or without musculoskeletal disorders.
METHODS: This is a systematic review, conducted in accordance with the
recommendations of the Reporting Items for Systematic Reviews and Meta-Analyses
(PRISMA). The databases used were Medical Literature Analysis and Retrieval
System Online (MEDLINE), Scientific electronic library online (SciELO), Physiotherapy
Evidence Database (PEDro), SCOPUS, Science Direct and Cochrane Central Register
of Controlled Trials. RESULTS: Eighteen studies were included, among which 13
studies had an uncertain to high risk of bias and another 5 studies had a low risk of
bias. In isotonic and/or isometric muscle strength, there was a difference between the
experimental and control groups in 4 studies, including 1 with a high load control group
and another 3 with control groups with an identical protocol without RFS, with no
significant differences being observed between the groups of 12 studies, 5 studies
among them, used high loads in their control group and another 7, an identical protocol
without RFS. Among the studies, 7 evaluated trophism, and in one of them there was
a difference between experimental and control, being its control a high-load protocol,
and there were no differences between the groups of the other 6 studies.
CONCLUSION: When it comes to upper limbs, low load training with BFR can promote
gains in strength and trophism similar to high-intensity protocols without BFR, and
protocols with BFR do not present significant differences in strength and trophism
outcomes compared to protocols identical without the BFR. However, the application
of BFR in the upper limbs can provide gains in strength in the shoulder, superior to low
load protocols without BFR, as long as at least two exercises for the shoulder muscles (agonists) are used. |
