自由式滑雪空中技巧运动员主要技术和心理控制研究

运用系统控制理论和最优化控制理论，采用实验室和现场实证研究相结合，群体与个体追踪研究相结合，心理指标、运动表现和运动绩效等多指标评定相结合的方法，对我国自由式滑雪空中技巧运动员的主要技术和心理控制进行研究。结果表明，现场监测与反馈训练能有效提高运动员助滑速度知觉的控制能力；多种表象训练可较好地促进运动员空中动作质量的提高；现场技术监控能有效地提高运动员着陆稳定性；多种心理训练方式可以较好地保持良好的赛前心理准备状态，从而保持运动员技术水平正常发挥。这一成果为尖子运动员获得优异成绩提供了科技支撑。同时，也为今后进行类似的研究提供了方法学借鉴。

Research on Main Techniques and Mental Control of Aerial Skier in Freestyle-Skiing

Based on theory of systemic and optimization control,this paper studies the main techniques and mental control of our aerial skiers in freestyle-skiing through combining method of laboratory and demonstration at site,group and individual tracing investigation.The result shows that inspection at site and feedback can effectively improve the control ability of speed perception in sliding phase.Imagery training should effectively promote the improvement of quality of action in the air.The technique monitoring at site can enhance the stability of landing.Several kinds of mental training can help skiers to maintain good mental state pre-competition and guarantee the normal performance.This accomplishment can provide the scientific support fir elite skiers to achieve the excellent performance.At the same time,it provides the reference for the same research in the future.
