Torque kinetics during elbow flexion (A) and knee extension (B) in boys (thin line) and men (thick line). In both groups, torque is expressed as a percentage of maximal torque, thus controlling for age-related differences in maximal torque. A significant group-time interaction was observed in both contractions (P < 0.01), with pair-wise differences at all time-points up to and including 90% MVC.
