Table 2 Mean ± SD values for IF (%), C.Perf (J) and BR (J) for differences between muscle groups (ER vs. IR), arm positions (45° vs. 90°), and dominance (dominant vs. non-dominant) in males and females considering interactions

From: Sex differences in shoulder performance fatiguability are affected by arm position, dominance and muscle group
