(A comparison of the take-off and the transition phase of the ski jumping between the group of the ski jumpers and the competitors in Nordic Combined events)
Take-off and transition phase were compared with the use of 2D videography by the competitors in ski-jumping and Nordic combined. The basic material was recorded at the events World Cup Liberec.99 and Championship of the Czech Republic. The quality of the motor abilities that are necessary for the performance was measured in the biomechanical laboratory tests. The take-off velocity as well as the vigour is greater together with the lower approach velocity in the ski jumpers. The competitors in Nordic combined realise the transition phase with greater rotation, the performance of the take-off is more variable. The value of the explosive force and the velocity in 15 m run is significantly greater in the ski-jumpers.
