title: Passive resistive torque of the plantar flexors following eccentric loading as assessed by isokinetic dynamometry.
abstract: Isokinetic dynamometers may provide a useful means of measuring muscle stiffness resulting from eccentric exercise because they can measure torque from computer-controlled passive movements of joints (passive resistive torque; PRT). In this study, a Biodex measured increased ankle PRT (52%; p <.001) following heel drop exercise in nine young women. Therefore, isokinetic dynamometers can provide a means to study group changes as a result of eccentric exercise. Future studies are required to determine the reliability of this protocol before it can be advocated in studying single cases.
