The loss of maximal isometric torque following a second LSI injury. If the second injury was performed 2, 3, 5, 7, or 14 d following the first injury the muscle was partially protected from torque loss, indicating a repeated bout effect (RBE). * P < 0.001 significantly different than first injury by ANOVA. N = 63 for the first injury and N ≥ 4 for all other groups.
