This study aims to compare the acute effects on hypoalgesia of training to failure using blood flow restriction (BFR) with dynamic occlusion versus BFR with fixed occlusion in patients with severe gonarthrosis. Two different training conditions will be performed with varying levels of blood flow occlusion (%BFR) and percentage of load (%RM): 1) 30% RM and 50% BFR with dynamic pressure; 2) 30% RM and 50% BFR with fixed pressure. Each participant will complete two individual sessions under different training conditions, randomly assigned with a 72-hour interval between sessions.
