This study inquires into the changes of muscles involvement in particular areas of the human motion system in the process of walking and nordic walking at people in their older adulthood. Nine probands, aged 50 – 60, were field tested in order to detect differences of the motion system during labour. Our attempt was to discover specific differences in the involvement of selected muscle groups in the areas of shoulder girdle, pelvic girdle and lower limbs, and to find out similarities of coordination attributes in horizontal locomotion presented by the pardigm of crawling kinesiological content of Vojta´s principle. In the areas of selected muscles we carried out the intra-individual comparative analysis of the resemblance of pairs muscle activation by a modified formulation of two signals correlative function. Furthermore, we tested their activity on the basis of so called triangular detection of the signal with the consecutive comparation of these types of locomotion. The results interpretation shows that during nordic walking there comes to the contralateral muscle connection between the lower body part and the shoulder girdle, which subsequently leads to the strengthening of these muscles and can be used as the prevention of vertebral column diseases or as a rehabilitation method. The shoulder girdle does not take over anti-gravity function, as it is at Vojta´s reflex crawling. It only takes part in the locomotion.
