Isokinetic training
Isokinetic training is a training method to increase muscle strength , which is particularly used in swimming training and rehabilitation .
While the effort required in conventional concentric muscle contraction varies due to the different angular positions (the greatest at a right angle, the smaller the angle, the smaller), in Isokinetic the resistance is changed in order to keep the effort the same. This is z. B. for the adductors of the legs by creating resistance with your own arms (or those of a partner), which changes depending on the angular position of the adductors. The flow resistance when swimming comes closest to Isokinetic.
As a rule, isokinetic training is carried out either with simple tractors (with centrifugal brakes) or with expensive computer-controlled machines (e.g. Cybex) in order to generate a resistance that, despite the changing power development possibilities of the muscle, still requires a steady effort.
Isokinetic training was first introduced on machines in 1966, first presented in German by Arnd Krüger in 1971. The advantages lie in the full use of force during the entire movement. All parts of the movement are strengthened equally. Muscle sore symptoms are avoided thanks to the even force distribution. The disadvantage lies in the unspecific adaptation, which no sport-specific innervation pattern corresponds to.
