SUMMARY:

 

Blood flow restriction training (RFS) has become considerably popular in recent years. Therefore, it is relevant to analyze the occurrence of side effects resulting from the technique. The aim of this study was (i) to systematize the scientific evidence on the effect of resistance training (TR) with RFS (TR + RFS) on muscle damage (DM) and (ii) to analyze the prevalence of side effects resulting from the technique. In the first study, two researchers independently and blindly searched the electronic databases: PubMed, Scopus, Web of Science, CINAHL, LILACS and SPORTdicus. Randomized and nonrandomized clinical trials that analyzed the effect of TR + RFS on DM markers in humans were included. Twenty studies were eligible for this review, encompassing 332 healthy participants (men, n = 281; women, n = 51). In 70% of the studies (n = 14), the samples were composed of untrained individuals. Most studies had more than one DM marker and late muscle pain was the measure most frequently used. The results for the occurrence of DM after low-load TR + RFS sessions were ambiguous and the use of a predefined repetition scheme versus muscle failure seems to be the discriminating point for this divergence, especially in untrained individuals. In the second study, 113 professionals who used the technique answered a self-administered questionnaire, consisting of 21 questions. The professionals reported applying the technique to individuals with different age groups, from the youngest (≤18 years; 3.5%) to the elderly (60-80 years; 30.7%), but mainly in people aged 20-29 years (74.6 %). Most professionals (99.1%) associated the RFS with resistance exercise. The main objectives pursued were muscle hypertrophy and physical rehabilitation, regardless of the modality used. One hundred and four (92%) professionals declare to have observed at least 1 SE resulting from the exercise with RFS. Most professionals observed tingling (71.2%) and late muscle pain (55.8%). Rabidomyolysis, fainting and subcutaneous hemorrhage were reported less frequently (1.9%, 3.8% and 4.8%, respectively). It is concluded that the technique is safe, considering that the prevalence of serious side effects is minimal. However, some methodological aspects, such as the use of sets until muscle failure is reached, should be considered in order to maximize the safety of the technique, especially in clinical contexts.
