Force and plantar contact area characteristics during push-off in cross-country skiing.

Popis výsledku v původním jazyce

The contribution is a descriptive study which deals with the basic kinetic characteristics (vertical ground reaction force) of major cross-country ski techniques and the size of plantar contact area during push-off. We observed and analysed these variables during push-off in diagonal stride (DS), double pole with kick (DPk), V1, V2 and skating without poling (SWP) at the race speed. T The measurement was made with the help of the Pedar system [Novel, GER]. Our observed group was composed of competitorsof top national performance level. We have found different values of maximal push-off force in the observed techniques. The value of ground reaction force was always higher in DS and DPk than in all skating techniques. In DS and DPk, the value of push-off force was not significantly different while on uphill or flat track. In DS, the values of vertical force reached 2.2 mBW on a flat part of track and 2.3 mBW uphill, in DPk 2.2 and 2.1 respectively. Similar results were found in flat and
