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 (р < 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.
提出了跳台滑雪运动员起跳瞬间身体姿势的运动学模型。创建了一种基于视频记录结果和办公信息技术来测量滑雪者身体坐标的方法。利用33名跳台滑雪运动员的体育比赛成绩，确定了起跳瞬间滑雪者身体姿势的运动学参数。确定了与跳跃长度具有统计学显著相关性（р < 0.03）的五个姿势参数。模型参数在跳跃长度总变化中的部分变化几乎等于53%，且相对相关性强且显著（p < 0.005）。制定了关于起跳瞬间身体姿势优化的建议。
