Blood Flow Restriction Training for The Shoulder

Healthy Clinical Trial

Official title: Blood Flow Restriction Training for The Shoulder: A Case for Proximal Benefit

Status Completed

Clinical Trial Summary

The aim of this study is to determine if BFR-LIX promotes greater increases in shoulder lean mass, rotator cuff strength, endurance, and acute increases in shoulder muscle activation compared to LIX alone.

Clinical Trial Description

Thirty-two healthy adults were randomized into two groups (BFRm=13,f=3, NoBFRm=10,f=6) that performed 8wks of shoulder LIX [2/wk, 4 sets (30/15/15/fatigue), 20%max] using common rotator cuff exercises [cable external rotation (ER), cable internal rotation (IR), dumbbell scaption (SCAP), and side-lying dumbbell ER (SLER)]. The BFR group also trained with an automated tourniquet placed at the proximal arm (50%-occlusion). Regional lean mass (dual-energy-xray-absorptiometry), isometric strength, and muscular endurance (repetitions-to-fatigue, RTF, 20%max, with and without 50%-occlusion) was measured before and after training. Electromyographic amplitude (EMGa) was also recorded from target shoulder muscles during endurance testing. A mixed-model ANCOVA (covaried on baseline measures) was used to detect within and between-group differences in primary outcome measures (α=0.05). ;
