Context:

It has been hypothesized that the fibers of the infraspinatus and subscapularis superior to the glenohumeral axis of rotation contribute directly to arm elevation.

Objective:

To test this hypothesis by assessing the impact of 5 weeks of concentric isokinetic humeral-rotator training in a modified neutral position on scapular-plane arm-elevation peak torque.

Design:

Prospective, pretest/posttest with control group.

Participants:

24 female and 6 male noninjured college students (N = 30).

Main Outcome Measures:

Scapular-plane-elevation peak torque at 60, 180, and 300°/s.

Results:

Repeated-measures ANOVA indicated no difference in peak torque between groups at any of the angular velocities tested (P < .05)

Conclusions:

5 weeks of concentric isokinetic humeral-rotator training did not significantly increase scapular-plane-elevation peak torque.
