Sažetak
On a sample of 30 best ski jumpers, the participants of the World Cup finals at Planica in 1990 and the World Cup start in the season 1993/94, we have analysed some kinematic characteristics in the phase of flight, and compared the differences between the classical and the new "V" technique of ski jumping. The comparison of the obtained results has shown that in the new technique ski jumpers are more inclined towards the front, that they form a smaller angle with the skis during the flight (viewed in the sagittal plane), that they are more bent in the hips and that they achieve considerably longer jumps at a lower height of the jump (observed somewhere in the middle of the flight). The length of the jump is, similarly as in the classical method, still to the greatest extent influenced by the flight height and the inclination of the ski jumper towards the front; however, a corresponding bent in the hips and suitable positioning of the skis in the air should also not be neglected.
