The action of a muscle that produces a movement at a constant speed or constant angular velocity over a joint's full range of motion. The muscle develops maximum tension over the complete range of motion. Some sports scientists suggest that the term isokinetic should not be used to describe a muscle action because isokinetic actions do not normally occur during sport or exercise performance; usually the linear movement of muscles varies in such performances. Furthermore, there is not even a guarantee that isokinetic actions occur on isokinetic machines. Although the controlled movement of the machine may be at a constant velocity, the velocity of the muscles generating the forces to produce the movement may vary
