Résumé : |
Blood flow restriction training (BFRT) provides an alternative approach to traditional strength training. The purpose of this study was to determine differences in quadriceps muscle activation, subject reported pain, and perceived exertion between three exercise conditions: low-load resistance BFRT with (1) regulated and (2) standardized devices, and (3) high-load resistance exercise without BFRT.
Design Randomized cross over study. Setting XX University Biomechanics laboratory. Participants Thirty-four healthy subjects (18 male/16 female) each completed three randomized sessions of knee extensions using Delfis Personalized Tourniquet System (R) at 30% of 1 repetition maximum (1RM), the B-Strong device (S) at 30% 1RM, and high-load resistance exercise (HL) at 80% 1RM. Main outcome measures Quadriceps EMG activity, numeric pain rating scale (NPRS), and perceived exertion (OMNI-RES) were recorded. Results Average and peak EMG were greater in HL sessions than both S and R (p .05) in average or peak EMG activation were found between S and R sessions. Conclusions Quadriceps EMG amplitude was greater during high-load resistance exercise versus low-load BFR exercise and there were no differences in EMG findings between BFRT devices. |
