We also know that the twitch duration responses depend on the type of muscle fibres. As mentioned before, we can distinguish slow, intermediate and fast twitch fibres, which obviously react differently. Moreover, differences in twitch duration are associated with variations of the frequencies that are necessary to reach the maximum tetanization of the fibres. Therefore, the frequencies used in electrotraining will obviously vary and will have to be adapted to the type of fibres that have to be tetanized.
Compex has developed several stimulation programmes takin,g into account this knowledge of twitch duration, the tetanization frequencies of the different types of fibres and the results of research and clinical studies. Each of these programmes is specifically based on the kind of muscle performance the user is interested in.
