AB The aim of this study was to verify the effects of blood flow restriction on movementvelocity and muscle activity during the back squat exercise. Methods: Twenty-four universitystudents participated in this study. In two randomized sessions 72 h apart, participants performed a4-set protocol consisting of 30-15-15-15 repetitions performed at 30% of their one-repetition maximumin the back squat exercise. In both sessions, neuromuscular function was monitored by surfaceelectromyography (EMG) and movement velocity (mean propulsive velocity (MPV), peak concentricvelocity (Vmax), and the effort index (EI)). Blood flow restriction (BFR) was applied during exercisein one of the experimental sessions with 80% of full arterial occlusion pressure over lower limbs.Results: The BFR condition showed higher (p < 0.05) EI, peak, and rooted mean square normalizedEMG in Set 1 compared to Set 2. Similar MPV and Vmax were observed in each set for both theBFR and control conditions. No significant differences were observed between conditions in anyset. Conclusions: BFR did not imply changes in neuromuscular performance during low-intensityresistance training, but it might induce greater intra-series velocity loss and less excitation of themuscles involved.
