Author's abstract

The aim of the present study is the presentation of new suggestions in EMG-processing. Using the examples of explosive MVCs and the high speed phase of sprint running the concerning two models dealing with recruitment order, fiber type contribution and fiber type characteristics try to uncover some deficits of present knowledge. In particular, the so far not respected impulse-force-relation of different fiber types and their consequences for EMGprocessing is discussed. Therefore two methods, a moving FFT and a digital band pass filtering, combined with a normalization of the resulting frequency bands are presented as a first attempt to solve the existing problems. Surface diagrams and graphs show interesting indications concerning the recruitment order and the use of frequency parameters. Verf.-Referat
