The aim of this study was to investigate the influence of fatty tissue layer on EMG signal parameters as a function of force level and type of muscle in young women. On the basis of body mass index (BMI) and the amount of fatty tissue (FT) 30 young women were divided into two equal groups: obese (O) and reference group (R). The EMG signal was measured on 5 levels of load from 2 muscles: palmaris longus (PL) and rectus abdominis (RA). The EMG signal parameters (RMS and MPF) were analysed. The results of the study suggest that the EMG signal is sensitive to fatty tissue layer. However, the influence of fatty tissue layer on the EMG signal is dependent on the muscle examined. The analysis of the dependence of the EMG signal on fatty tissue layer based on more detailed parameters of the power spectrum is desirable.
