Isokinetic Exercise
Pronunciation: eye-so-ki-NET-ik
A type of strength training where muscle contractions occur at a constant velocity throughout the range of motion.
Full Definition
Isokinetic exercise involves muscle contractions performed at a predetermined, constant angular velocity using specialized computerized equipment. Unlike isotonic or isometric exercises, the resistance automatically adjusts to match the force applied by the patient throughout the entire range of motion. This allows for maximum muscle activation at all joint angles and provides objective data on strength deficits. Isokinetic testing and training are particularly valuable for athletes returning to sport and for documenting strength improvements in clinical settings.
Usage
Usage note: Often confused with isotonic; emphasize the constant velocity aspect in documentation.
