Fig. 1From: Isometric blood flow restriction exercise: acute physiological and neuromuscular responsesChange in muscle activation between LL-BFR (filled circle) and LL (filled squares) across the three sets (a). The data points show the EMG activity in 10 s intervals within each set. There was a significant higher EMG level in each of the sets in the BFR condition (b). Data are presented as mean and SEM. *** = p = 0.0005, **** = p < 0.0001Back to article page
