Note: BD = Biodex; EC = Eccentron; ECC = eccentric; CON = concentric; ISM = isometric; IST = isotonic; PT = peak torque; PF = peak force; PP = peak power; RTD = rate of torque development; RFD = rate of force development; PV = peak velocity; UNL = unloaded concentric velocity; SLT = single-leg stance time. * indicates a significant effect for limb, collapsed across age group. ⱡ indicates a significant group × limb interaction (see text for explanation). † indicates p = 0.051 for the group × limb interaction. ** indicates higher vs. dominant limb for the young group only. p < 0.05 for determining statistical significance.
