Abstract
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). Th e 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 fi gures of maximal force for both technique, usually higher for open fi eld and V1 technique than for V2 skating, the higher force during the skating on the fl at terrain than on the slope for training and race speed.
Th e average value of maximal force on the fl at terrain during open fi eld 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 fi eld or V1 skating and 1 – 1,2 (BW) for V2.
