Isokinetic exercise

The concept of isokinetic exercise was described in 1967 by Hislop and Perrine. Isokinetic exercise can best be described as movement that occurs at a constant angular velocity with accommodating resistance. Maximum muscle tension can be generated throughout the range of motion because the resistance is variable to match the muscle tension produced at the various points in the range of motion. Isokinetic machines allow the angular velocity to be preset. Once the specified angular velocity is achieved, the machine provides accommodating resistance throughout the specified range of motion.
