What is Isokinetic
Isokinetic (n) is a term used to describe a type of movement or exercise.
Isokinetic or Isokinetics Definition:
The word isokinetic is most commonly used in sports science and medicine. In these settings isokinetic defines a type of exercise or movement.
Isokinetic movement is actually the opposite of isotonic movement which is probably the easiest way to think of it. Isotonic movement is the most common type of movement we human beings perform:
Isotonic movement:
In almost every situation, every day, we perform isotonic movements. In these types of movements we pick up a fixed weight, an empty pan basically anything that has weight. The weight of the pan is fixed but we decide how fast to lift it. We can lift it slow, fast, or anywhere in between. The key to this type of movement is we decide how fast it goes but the weight (resistance) remains constant.
Isokinetic movement:
In isokinetic movements the situation is reversed now we tell an isokinetic machine (the dynomometer) to move only at a certain speed (normally described in degrees per second). The machine will then vary it's resistance against us to maintain that speed. This means if we push against the machine hard it will give back allot of resistance to maintain the speed it was told to go at. If we push or pull softly the machine reduces the weight to maintain the speed.
To achieve isokinetic movement there are many different ways of developing the resistance, however, most people use an isokinetic device. Isokinetic devices are referred to as isokinetic machines and they vary vastly in technology and price.
Most medical isokinetic machines are top of the range. They use a powerful motor to provide the isokinetic resistance to the force applied and then use a computer to keep the motion smooth, provide the acceleration and to record the results. In medical systems the components (the motor, gear box and computer control) are what make the machines so very expensive but they

    Contractions that permit the muscle to shorten are referred to as concentric contractions. An example of a concentric contraction in the raising of a weight during a bicep curl. In concentric contractions, the force generated by the muscle is always less than the muscle's maximum. As the load the muscle is required to lift decreases, contraction velocity increases. This occurs until the muscle finally reaches its maximum contraction velocity. By performing a series of constant velocity shortening contractions, a force-velocity relationship can be…

    Muscle contractions tend to be smooth and vary in strengths, depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded, either by changing the frequency of stimulation or by changing the strength of the stimulation.…

    Some research on post activation potentiation and force rate relationship have mostly involved isometric contraction, type of muscle contraction affects rate of frequency and force frequency over which post activation potentiation happens. In concentric muscle contraction (CMC), especially at high velocity the force frequency relation is transferred to the right compared to the isometric muscle contraction (IMC), this is because high frequency is needed to induce a desired percentage of maximum force Abbate, et al., (2000). PAP still plays a major role to high frequency in concentric vs isometric contraction for example Rowling, swimming and cycling involve concentric movement and concentric-eccentric contraction can be weightlifting, running…

    8. Isotonic contraction (“same tone” or tension) - In isotonic contractions, myofilaments are successful in their sliding movements, the muscle shortens, and movement occurs. Contractions in which the muscles do not shorten are called isometric contractions (“same measurement” or length). In isometric contractions, the myosin mysofilaments are “skidding their wheels,” and the twnaion in the muscle keeps increasing.…
