isokinetic

 [i″so-kĭ-net´ik]
pertaining to a concentric or eccentric contraction of a muscle in which the speed and tension are constant throughout the range of lengthening or contracting.

isokinetic

/iso·ki·net·ic/ (-kĭ-net´ik) maintaining constant torque or tension as muscles shorten or lengthen; see isokinetic exercise, under exercise.

isokinetic

[-kinet′ik]
pertaining to a concentric or eccentric contraction that occurs at a set speed against a force of maximal resistance produced at all points in the range of motion.

isokinetic

without change in velocity. isokinetic activity movement of an object, body or body segment, by muscle action, with constant velocity. Sometimes known as isovelocity motion: rare in sport. isokinetic dynamometer device for measuring moments at a constant velocity. The machine controls velocity (usually angular velocity) and external moment is measured. Sometimes known as isovelocity dynamometer . See also torque-angular velocity relation.
