An Isokinetic exercise


An Isokinetic exercise is a type of dynamic exercise in which the speed of muscle shortening or lengthening and the angular limb velocity is held in constant by a rate-limiting system generally recognized as an isokinetic dynamometer. The Isokinetic time period is signifies that the movement happen with the velocity of the muscle stays constant. The load is change varies to coach the velocity of the limb movement.

Isokinetic Dynamometer

The advantages of the isokinetic dynamometer are that it could measure the energy of the muscle and strengthening the muscle.

It is mainly used to measure muscular power in musculoskeletal rehabilitation with the aim of regain the optimal type of operate after harm or surgery. During the final stage of rehabilitation goals to return an individual to normal activities via resistance workouts which may be usually centered on regaining muscle strength. Isokinetic dynamometer assist to scale back the probability of injury as the resistance and speed of the exercise are managed, straining the muscle tissue is very unlikely.

Other than that, the parameter of the dynamometer can be set, so the affected person in a place to carry out the identical muscle in concentric mode and followed by the eccentric mode so as to strengthen the group of muscle at a time. In addition, it could possibly lodging to a painful arc. If a affected person experiences momentary pain at one level of the arc of motion during resistance exercise, isokinetic coaching accommodates for the painful arc. The patient can simply pushes in much less effort to against the resistance arm to move inside the pain-free region by way of that portion of the vary.

If a affected person can not proceed the resisted movement because of sudden onset of pain, the resistance is eliminated as soon because the affected person stops pushing against the torque arm of the dynamometer.

The advantages of the isokinetic dynamometer

It can set up a quantitative measurement of the muscle performance in opposition to which improvement may be judged. This machine are more applicable during the intermediate and advanced phases of rehabilitation when the muscle power is 4/5 or higher or when the muscle strength exceeds the energy of the therapist. Also, it can be used to make a training impact on the strong muscle group by utilizing the heavy load, as a substitute of utilized manually by the therapist.

It can even improve the resistance in a extra quantitative and intermediate. It is helpful for bettering the dynamic or static muscular power and muscular endurance. By utilizing isokinetic dynamometer the high-velocity resistance is possible and secure .final but not least, nearly any joint action can be examined by the adjustment of the equipment.

The disadvantage of the isokinetic dynamometer

It just isn’t suitable to make use of when the muscle are very weak or the delicate tissue is still within the early phases of the therapeutic course of. As the tools only exert constant exterior resistance maximally on the muscle on one level in the vary of motion. In addition, the increase of resistance only depends on the manufacture’s increment of resistance. Other than that, the equipment is expensive and extremely price in the maintenance of the tools. It also required a big area to install the machine.


In a conclusion, isokinetic dynamometer might enhance the muscular power of the affected person. An isokinetic dynamometer is a dependable tool for isokinetic muscle performance measurement and able to assess muscle energy more objectively, than the manual resistance exercise.
