|August 22, 2020
Summary
Blood flow restriction (BFR) training did not enhance rotator cuff strength or tendon size compared to exercise alone. However, high-repetition, low-load exercise significantly increased rotator cuff strength and tendon size.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Orthopedics
Background:
- Blood flow restriction (BFR) training involves using a tourniquet to limit blood flow during exercise.
- BFR has shown potential for increasing muscle strength and size.
Purpose of the Study:
- To investigate if BFR enhances rotator cuff strength and tendon size.
- To compare outcomes between BFR with exercise versus exercise alone.
Main Methods:
- Forty-six participants were randomized into two groups: BFR + exercise or exercise only.
- Both groups performed side-lying external rotation exercises 2 days/week for 8 weeks at 30% of 1-repetition maximum.
- The BFR group used a tourniquet on the upper extremity during exercise.
Main Results:
- Both groups showed significant increases in rotator cuff strength (supraspinatus and external rotators).
- No significant difference in strength gains was observed between the BFR and exercise-only groups.
- Both groups exhibited increased supraspinatus tendon thickness, with no significant difference between groups.
Conclusions:
- BFR applied to the upper extremity did not provide additional benefits for rotator cuff strength or tendon thickness compared to exercise alone.
- High-repetition, low-load exercise effectively increased rotator cuff strength and tendon size, regardless of BFR application.
