Acute Exercise Responses With Blood Flow Restriction Under Dynamic Pressure Compared to Fixed Pressure in Patients With Severe Gonarthrosis
Sponsor: University of Valencia
Summary
This study aims to evaluate the acute effects of blood flow restriction (BFR) training on hypoalgesia and neuromuscular responses in patients with severe gonarthrosis by comparing the application of pressure with a dynamic versus a fixed configuration. There will be six different training conditions 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; 3) 50% RM and 50% BFR with dynamic pressure; 4) 50% RM and 50% BFR with fixed pressure; 5) 30% RM and 80% BFR with dynamic pressure; 6) 30% RM and 80% BFR with fixed pressure. Each participant will complete six individual sessions under different training conditions, assigned in a random order with a 72-hour interval between each session.

Low-intensity resistance exercise with moderate arterial occlusion pressure and dynamic pressure.
A single quadriceps extension exercise at 30% of 1 repetition maximum (1RM) with dynamic occlusion at 50% of limb occlusion pressure (LOP), performing 4 sets of 30, 15, 15, 15 repetitions with 30 seconds of rest between sets.
Low-intensity resistance exercise with moderate arterial occlusion pressure and fixed pressure.
A single quadriceps extension exercise at 30% of 1RM with fixed occlusion at 50% of limb occlusion pressure (LOP), performing 4 sets of 30, 15, 15, 15 repetitions with 30 seconds of rest between sets.
Moderate-intensity resistance exercise with low arterial occlusion pressure and dynamic pressure.
A single quadriceps extension exercise at 50% of 1RM with dynamic occlusion at 30% of limb occlusion pressure (LOP), performing 4 sets of 30, 15, 15, 15 repetitions with 30 seconds of rest between sets.
Moderate-intensity resistance exercise with low arterial occlusion pressure and fixed pressure.
A single quadriceps extension exercise at 50% of 1RM with a fixed occlusion of 30% of the limb occlusion pressure (LOP), performing 4 sets of 30, 15, 15, 15 repetitions with 30 seconds of rest between sets.
Low-intensity resistance exercise with high arterial occlusion pressure and dynamic pressure.
A single quadriceps extension exercise at 15% of 1RM with a dynamic occlusion of 80% of the limb occlusion pressure (LOP), performing 4 sets of 30, 15, 15, 15 repetitions with 30 seconds of rest between sets.
Low-intensity resistance exercise with high arterial occlusion pressure and fixed pressure.
A single quadriceps extension exercise at 15% of 1RM with a fixed occlusion of 80% of the limb occlusion pressure (LOP), performing 4 sets of 30, 15, 15, 15 repetitions with 30 seconds of rest between sets.
