| Description | The contribution is the descriptive study which is dealing with the basic kinetic characteristics of main cross country ski skating techniques. We observed and analysed the leg force during the stroke for open field skating or V1 and V2 skating. Next we studied the time of the stroke (kick). The measurement was made with the help of the system Pedar [Novel, GER]. Our observed group created the high performance level competitors, who`s placed till 25th in the SLCR ranking. We found out the various figures of maximal force for both technique, usually higher for open field and V1 technique than for V2 skating, the higher force during the skating on the flat terrain than on the slope for training and race speed. The average value of maximal force on the flat terrain during open field or V1 skating were 1,2 – 1,5 multiple of body weight (BW), for V2 skating we found 1,1 – 1,4 (BW). In the uphill the value were 1,2 – 1,4 (BW) for open field or V1 skating and 1 – 1,2 (BW) for V2. |
