Description

The Athletic Shoulder (ASH) test was developed to measure shoulder girdle force for assessing isometric strength in athletes. This study compared force production between dominant and non-dominant arms in two positions. Participants performed three bilateral maximal contractions at 180º ("I") followed by three maximal contractions at 135º ("Y") of shoulder abduction. Peak force was measured for each trial with maximal peak and mean force of the three trials calculated for analysis. No significant main effects were observed between positions or arms for maximal or mean peak force (p > 0.05). Mean peak force for both arms in the "I" and "Y" positions ranged from 95N to 107 N. The findings suggest collegiate male volleyball athletes exhibit no detectable isometric force imbalances between their arms, regardless of position.
