Dependence of ski jump length on the skier's body pose at the beginning of take-off.

A kinematical model of the ski jumper's body pose at the beginning of take-off was proposed. A method of measuring skier's body coordinates based on the results of video recordings and office information technologies was created. Kinematical parameters of the skier's body pose at the beginning of take-off were determined using sport competition results of 33 ski jumpers.
