摘　　要：目的:研究平昌冬奥会自由式滑雪空中技巧女运动员的赛场表现及动作难度、难度战术发展趋势。方法:采用视频分析等研究方法,对平昌冬奥会自由式滑雪空中技巧决赛女运动员的赛场表现进行对比分析,并与索契冬奥会女运动员的动作难度系数及难度战术情况进行对比,分析动作难度选择与难度战术的发展趋势。结果:(1)平昌冬奥会决赛女运动员动作难度范围为2.900~4.050,3轮的动作平均难度系数分别为3.267±0.215、3.500±0.247和3.658±0.221;(2)决赛次轮和末轮中女运动员均有加难、有限减难和维持难度的战术选择,白俄罗斯队与中国队还制定了团队难度战术;(3)决赛中女运动员们的落地成功率为66.7%,动作的平均质量系数为0.88,女运动员在腾空、动作表现和落地上分别表现不同的优势与劣势;(4)平昌冬奥会中末轮动作难度系数与索契冬奥会相比明显下降;(5)两届冬奥会决赛中女运动员的难度战术选择变化趋势不显著,团队难度战术也相同。结论:自由式滑雪空中技巧女运动员在冬奥会决赛末轮中的动作难度系数有显著下降趋势,但个人与团队难度战术选择无显著性变化趋势。The purpose of the paper is to study the performance of aerial female athlets in Pyeong Chang Winter Olympics and the developing trends of degrees of difficulties and the difficult tactics. Methods： With the methods of video analysis and the others,the paper compared and analysed the performance of aerial female athlets in Pyeong Chang Winter Olympics,as well as compared the degrees of difficulties and the difficult tactics with the ones in Sochi Winter Olympics,so as to analyze the developing trends of them. Results：（ 1） The range of difficulties of female aerial athlets in Pyeong Chang Winter Olympics was 2. 900 to4. 050,and the average coefficients of difficulties in the three rounds were 3. 267 ± 0. 215,3. 500 ± 0. 247 and 3. 658 ± 0. 221,respectively.（ 2） In the second and the last round offanals,difficult tactics of improvement,maintenance as well as declining were selected by male athletes.（ 3） The Success rate of ground landing was 66. 7%,and the average coefficient of quality of actions was 0. 88. Athlets have different pros and cons on air,form and landing.（ 4） Comparing to the Sochi,the coefficient of difficulties in the last round of the Pyeong Chang Winter Olympics was significantly declined.（ 5） There was no significant change trend was found for the choice of difficult tactics in female finals in the Sochi and Pyeong Chang Winter Olympics,and the difficult tactics for teams were indentical. Conclution： Significant trend of declining was found on the coefficient of difficulties in the last round of the Winter Olympics,while no significant change trends of the difficult tactics were found in the individual and the team choices.
