主要采用调查访问法、录像观察法,对1994年至2006年4届冬奥会女子自由式滑雪空中技巧比赛所有使用三周动作的9个国家14名选手及其48跳次三周动作进行了系统研究。结果得出:从第17届至第20届冬奥会,两跳三周动作平均难度从6.28升至7.57,着陆成功率从14%升至61%,平均动作质量系数从0.70升至0.79,经过12年的发展其三周动作已实现了质的飞跃;与前3届冬奥会相比,第20届冬奥会女子空中技巧三周动作的使用效益最大,这将对今后该项目的技术发展与实力格局产生重要影响。
Mainly using the method of interview and interview, the video observation method was used to evaluate the 14 athletes in 9 countries and their 48-jump three-week movements using all three weeks of the four-time Winter Olympic women’s freestyle skiing aerials competition from 1994 to 2006 system Research. The results showed that from the 17th to the 20th Winter Olympics, the average difficulty of two-hop and three-week movements increased from 6.28 to 7.57, the landing success rate increased from 14% to 61% and the average movement quality coefficient increased from 0.70 to 0.79. After 12 years of development, its three weeks’ action has achieved a qualitative leap. Compared with the previous three Olympic Winter Games, the effectiveness of the three-week action of the women’s aerial skills in the 20th Winter Olympic Games is most beneficial. Technology development and strength have a significant impact on the pattern.
