Abstract
The skiing is a very old human locomotion on the snow. During the last century, it became very popular winter and Olympic sport, currently profiting from its great popularity among the public.
New cross country skiing technique – skating – has been developing very dynamically since the eighties years of the 20th century. This presented study deals with a comparison of muscles activation during skating technique on skis and on roller skis.
We studied tree base styles of skating: V-1 on right and left side and V-2. The beginnings of important activation of the muscles on a right leg and their subsequent deactivation during one step cycle were measured with surface electromyography (SEMG).
The results confirm the idea that we can consider roller skiing as a special training device of cross country skiing. This is correct from the kinetic view as well as from the connection of muscles.
The biggest differences in phase shifts of muscle unit activation were found between V-1 on left side during cross country skiing and roller skiing.
