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.
