Similar Regional Hypertrophy of the Elbow Flexor Muscles in Response to Low-Load Training With Vascular Occlusion at Short Versus Long Muscle Lengths.

ABSTRACT:

Background

The regional hypertrophy response of elbow flexor muscles was compared after unilateral elbow flexion training in extended versus flexed shoulder position under vascular occlusion, which can induce muscle hypertrophy in the absence of muscle damage-induced edema/swelling.

Hypothesis

Hypertrophy of elbow flexor muscles would be greater in extended compared with flexed shoulder position.

Study design

Randomized within-subject trial.

Level of evidence

Level 2.

Methods

A total of 21 resistance-trained men (age, 25 ± 5 years; height, 1.78 ± 0.07 m; weight, 79.3 ± 13.1 kg) performed unilateral elbow flexions with one shoulder extended/elbow flexor muscles lengthened/long muscle length (LONG) and the other flexed/elbow flexor muscles shortened/short
