The submitted paper discusses surface tension of individual muscles during athletic sprinting and a special running exercise (further only SRE), in this case skipping, measured by the analysis of electromyography record. We have measured sprint and SRE on the distance of 30 metres. At the same time the movement was synchronically video recorded from the side position of a video camera. The aim of this study was to describe the inclusion of individual muscles during sprint, but mainly how muscles participate when realizing skipping. The second aim was to describe to what extent muscles participate similarly during skipping with regard to the final movement - sprint. Furthermore, we can determine and describe how the exercise with its content is drawing on the final movement and if it fulfils at the same time the requirements of a special exercise rather than a generally eveloping exercise. The presumption is that skipping will fulfil the role of a special developing exercise only in a certain phase of movement, for which it is also preferentially used.

Kick-biking and running at above average intensity were examined in terms of muscle activation. Surface electromyography was used to evaluate the timing of muscle activity. The electric potentials of seven lower limb muscles were detected by unique KaZe05 mobile apparatus during both activities. Cross-correlation analysis was introduced to compute the similarity in muscle behavior as well as the timing of muscle activation. Similar mechanisms in terms of timing and motor control were identified for lower limb extensors. The kick-bike seems to be efficient tool in teaching partial running skills.
