Abstract
Due to the primarily cyclical movement patterns in alpine skiing, it is hypothesized that the methods used to analyze running and cycling are applicable to the complex activity alpine skiing. There appears to be potential for a more in-depth analysis of muscle activity during alpine skiing, by the use of wavelets. Thus, the aim of the current project was to perform a time-frequency analysis of the EMG intensities during alpine skiing using wavelet transformation. Functional differences in EMG time and frequency patterns within the quadriceps muscles where analyzed. The current topic was chosen because of a previous study by Berg et al (1995) who reported differences within the quadriceps muscles with respect to only EMG amplitudes. Einleitung gekürzt
