Abstract This study investigated the acute physiological responses during sport-specific repeated sprint training with different levels at blood flow restriction (BFR) in elite boxing athletes. Sixteen female boxers participated in this randomized, cross-over study. All boxers conducted four tests under different conditions, each consisting of 3 sets of 6 repetitions of 10-sec all-out punches in non-BFR, BFR-45%, 60%, 80% arterial occlusion pressure (AOP45, AOP60, and AOP80).
