The Comparative Analysis of Free Technique Cross Country and Skating on Roller Skies
Vol.7,No.2(2013)
Skiing is a very old human activity on snow. During the last century, it has become a very popular winter and Olympic sport, currently profiting from its great popularity among the public. A new cross country skiing technique – skating – has been developing very dynamically since the 1980’s. This presented study deals with a comparison of muscles activation during the skating technique on skis and on roller skis. We studied three base styles of skating: V-1 on right and left side and V-2. The important activation of the muscles on a right leg and their subsequent deactivation during one a step cycle were measured with surface electromyography (SEMG). The results confirm the idea that we can consider roller skiing as a special training device for cross country skiing. This is correct from the kinetic view as well as from the connection of muscles. The biggest difference in phase shifts of muscle unit activation were found between V-1 on left side during cross country skiing and roller skiing.
