Isokinetic exercise is a form of dynamic exercise in which the velocity of muscle shortening or lengthening and the angular limb velocity is predetermined and held constant by a rate-limiting device known as an isokinetic dynamometer. The term isokinetic refers to movement that occurs at an equal (constant) velocity. Unlike DCER exercise where a specific […]

A dynamic muscle contraction causes joint movement and excursion of a body segment as the muscle contracts and shortens (concentric contraction) or lengthens under tension (eccentric contraction). The term concentric exercise refers to a form of dynamic muscle loading where tension in a muscle develops and physical shortening of the muscle occurs as an external […]

The velocity at which a muscle contracts significantly affects the tension that the muscle produces and subsequently affects muscular strength and power. The velocity of exercise is frequently manipulated in a resistance training program to prepare the patient for a variety of functional activities that occur across a range of slow to fast velocities.
