Grip widths of 100, 130, 165, and 190% (G1, 2, 3, 4, respectively) of biacromial breadth were used. Mean integrated myoelectric activity for each muscle and at each grip width was determined for the concentric portion of each 1-RM and normalized to percentages of max volitional isometric contractions (%MVIC). Data analysis employed a one-factor (grip width) univariate repeated measures ANOVA. Results indicated significant main effects for both grip width (p=0.022) and muscles (p=0.0001). Contrast analyses were conducted on both main effects. Significant differences (p
