D, dominant limb; ND, non-dominant limb; CI, confidence interval; (%BM), absolute values of peak torque corrected by body mass and expressed as a percentage of this; H:Q ratio, hamstrings-to-quadriceps ratio. Data are presented as mean (SD). The variables peak torque and H:Q ratio were analyzed using a paired t-test, and the variables average power and total work were analyzed using a Wilcoxon test.
