Abstrakt     Many studies have been made to answer a polemical question - how do muscle work. One of the aspects is to study the muscle response - but how to measure it? Our main aim was to build a measuring system that would be simple to use, non-invasive, and would measure the muscle response direct to the muscle. The measuring method that was used is based on a magnetic displacement sensor measuring the muscle belly radial displacement. The sensor is placed adjacent to the skin over the muscle and measures radial movements of the muscle belly. We observed the muscle response to electrical stimulation. Different muscles or muscle groups have different responses. The parameter that was found to be interesting for studying was the rise time of the muscle belly response. Comparison of muscles' responses due to normalized rise time parameter confirms known division to 'slow' and 'fast' muscles. The parameter of a 'fast' muscle was four times greater than the parameter of a 'slow' muscle. The aim of the study is to estimate how the measured data obtained with recent knowledge about skeletal muscles dynamics. The proposed measuring method contributes to a better understanding of skeletal muscles' dynamic properties. It offers a possible way of studying the muscle structure from the muscle's response to electrical stimulation.
