Abstract
Background:
There are over 2800 articles on blood flow restriction (BFR) in PubMed; only 11 include the shoulder.
Purpose:
The purpose was to determine effects of BFR training on the strength of shoulder internal (IR) and external rotators (ER). We hypothesized both control (C) and experimental (E) groups would significantly improve in shoulder strength. Subjects in E (BFR) would show significantly more improvement than C. C will have non significant gains in contralateral extremity. E will significantly increase strength in contralateral extremity.
Methods:
Subjects completed informed consent, PAR-Q, and demographic forms. Subjects were randomized into C and E groups. All subjects were pre and post tested with a Hand Held Dynamometer (HHD) by blinded assessor with ICC reliability = 0.830. Subjects performed warm-up, trained with TheraBand using 4 sets x 30/15/15/15 reps x 60-80% OMNI-RES scale, 2x week for 6 weeks using shoulder IR/ER. The E group used BFR with 50% limb occlusion pressure (LOP).
Results:
Paired samples t-test concluded there were significant differences between pre and post testing within C (p=0.001) and E groups (p=0.001-0.006) for both IR/ER of D/ND. There were no significant differences between C and E groups (p=0.327-0.965). Both groups had significant improvement in untrained arm (p=0.000-0.006).
Conclusion/Outcomes:
The results did not support all of the hypotheses. The results of this study demonstrate that BFR can be applied to selected subjects to create an improvement in their strength.
Program Description
Determine effects of BFR training on shoulder strength of internal and external rotators. We hypothesized control (C) and experimental (E) groups would significantly improve. Subjects in E (BFR) would significantly improve more than C. C will have non-significant gains in contralateral extremity. E will significantly increase strength in contralateral extremity.
