Abstract
Nordic walking (NW) has been recently presented as a miraculous motor activity, which should replace bipedal walking mainly in seniors' motor stereotypes. A series of our studies investigated the dynamics of coordination indicators of selected areas of motor system during the free bipedal walking and NW through surface electromyography with the synchronized video record.
We have found muscle teamwork in the area of shoulder girdle during NW, which indicates the return to the locomotion realized through this girdle during the human postural motor ontogenesis. Initiation of these muscle co-activations is used in the treatment rehabilitation.
In the pelvis area we have found a phenomenon, which indicates the decrease of demands on side stabilization of pelvis during NW. The study results, realized with 12 tested persons, question the uncritical popularization of the commonly known beneficial impact of NW.
