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. Five parameters of the pose which show statistically significant correlation ( đ < 0.03) with the jump length were determined. A part of variation of the model parameters in the total variation of the jump length is almost equal to 53%, and relative correlation is strong and significant ( p < 0.005). Recommendations regarding optimization of the body pose at the beginning of take-off were formulated.
