Isokinetic peak torque
Isokinetic peak torque and isometric strength will be determined for the knee flexors and extensors using a Biodex isokinetic dynamometer (NEPS Lab-Tufts). Peak torque measurements will be obtained with the subjects seated and the knee fully extended. Peak torque will be measured at 0, 60, and 240°.sec-1. These specific angular velocities have been selected because of their association with functional performance and excellent reliability in this population.
