(A) Average ratings of perceived exertion (RPE), (B) shoulder flexion maximum voluntary contraction (MVC), and (C) grip MVC for the proximal (squares) and distal (circles) fatigue sessions after the pre-test, fatigue, and post-test on each day. MVCs are reported as a percentage of the initial MVC. Error bars represent 95% confidence intervals. * indicates a difference from baseline strength.
