对刘子歌备战第29届奥运会200m蝶泳技术攻关研究

Research on 200m Butterfly Stroke Techniques of LIU Zi-ge Prepared for the 29^(th) Olympic Games

对刘子歌备战第29届奥运会的蝶泳技术全面解析认为,刘子歌蝶泳属于呼吸配合时机好,上下起伏小,游进中减阻技术好的小波浪蝶泳技术,符合现代蝶泳技术发展趋势;身体、体能条件也是非常出色的,具备冲击世界最高水平的条件。在备战北京奥运会攻关期间,针对刘子歌技术将攻关研究分为两个阶段,通过对其出发转身的技术改进,于2008年绍兴冠军赛以2 min7 s76超越此前本人最好成绩2 s39并夺冠,获得奥运会200 m蝶泳的参赛资格;第2个阶段通过对其途中游抱水和推水技术的改进,最终在第29届奥运会上以2min4 s18的成绩夺取金牌并打破世界纪录,证明对其技术训练的研究和攻关,所提出的技术训练对策、方法有效。

After comprehensive analysis on butterfly stroke techniques of LIU Zi-ge prepared for the 29th Olympic Games, it was found that the butterfly stroke technique of LIU Zi-ge is small wave butterfly, which breathe better with time, up and down small and is good at drag reduction in swimming process. The techniques are in line with the development trends of modern butterfly technique. Her physical fitness and condition is good enough to top the world ＇s highest level. During the research period of preparing the Beijing Olympic Games, the research process has been divided into two stages, which is based on the technique of LIU Zi-ge. After the technical improvements of her starts and turns, she won the championship on the 2008 Shaoxing Championship by 2minTs76, which is beyond the former best score 2s39, and obtained the Olympic 200m butterfly entry qualifications. The main job of the second stage is to improve the techniques of catch and pull in swimming process. She finally won the gold medal of 200m butterfly on the 29th Olympic Games by 2min4s18, which break the world record. The result of Olympic Games and the analysis of technique and tactics indicate that the countermeasures and methods proposed are effective to the research of technical training.
