Safety and Effects of High-Intensity Blood Flow Restriction Training in the Rotator Cuff
Sponsor: University of Valencia
Summary
This study aims to analyze the effects of an 8-week strength training program combining different exercise intensities and blood flow restriction (BFR) conditions on safety, tolerability, muscle adaptations, and physical performance variables. Three training modalities will be compared: 1) high-intensity exercise with BFR therapy; 2) low-intensity exercise with BFR therapy; and 3) high-intensity exercise without BFR therapy. All groups will perform the same exercise modality, differing only in intensity and the application of BFR. Participants will be randomly assigned to one of the three groups and will undergo a 8-week intervention. The variables of interest will be assessed in each group for subsequent analysis and comparison.

Interventions
High-intensity exercise with BFR
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 70% RM and a 50% of arterial occlusion pressure. 30" rest between sets, 2' rest between exercises.
Low-intensity exercise with BFR
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a 50% of arterial occlusion pressure. 30" rest between sets, 2' rest between exercises.
High-intensity exercise without BFR
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 70% RM and a without flow restriction application (cuff applied without pressure). 30" rest between sets, 2' rest between exercises.
