Abstract

The purpose of this study was to observe, analyze and compare electromyographic (EMG) signal of the leg muscles during the cross country (XC) classic ski technique skiing by classical technique (represented by diagonal stride) and pedalling on stationary bike.The data were collected by surface electromyography method (SEMG), and by synchronized video recording. Acquired data were processed by software MatLab and MegaWin, the video recording was processed with Dartfish SW.Established values of correlation and covariance show higher level of exactingness for holding of dynamic balance during cross country skiing in comparison with cycling on the stationary bike.

We found high levels of co-contraction of all analyzed muscles during the cross country skiing. During Pedalling were the muscles activated and deactivated continually.This study confirmed high level of demands for m. tibialis anterior by in cross country skiing.

It is necessary as for the ending of kick as for stabilization knee join and all leg and so all body during glide phase.
