The lower trapezius (LT) muscle is important for normal shoulder function. Evidence for optimal strengthening exercises and dosage for a weak LT muscle does not exists. Our goal was to determine if purported LT strengthening exercises are effective. Shoulder external rotation, prone elevation in the scapular plane, and scapular retraction were used in this study. Fifty-five healthy participants (33 experimental; 22 control) between the ages of 20-30 participated. Strength was assessed with hand held dynamometer pre-training and post-training at 4, 8, and 12 weeks. A mixed 2-way ANOVA assessed differences between experimental and control LT strength at the various time frames. Results found no difference between experimental and control groups LT strength pre-training and post-training 4, 8, and 12 weeks.
