Abstract

From a neurophysiological point of view, the acquiring and optimising of motor skills are reflected (among other things) in a changing increase of myoelectric activity. The process of economising is determined by an improved neurological control of the muscles involved (shorter pre-inervation-phase, better co-ordinated recruiting/frequentation of active motor units). Thus the muscle reaches increasingly better the optimal level of activity which is adequate for the situation or the specific skill. As well as analytical EMG-code-values of time like relative timing and sequencing, the EMG-parameter "type of increasing in electric muscular activity" could provide interesting information about changes of the inter- and intramuscular co-ordination of complex motor skills based on learning and practising. It allows to diagram and quantify the development of muscular power in time. The article in hand represents an own computer controlled modelling of regression for quantifying the type of increase in myoelectric activity of fast complex movements. Aus der Einleitung
