水下蝶泳腿技术动作分析 摘要: 水下蝶泳腿技术，即Underwater Undulatory Swimming，简称UUS，是一套非常有效的游泳技术。接受水下蝶泳打腿技术训练的运动员要比那些没有采取此项技术的选手在出发和转身阶段所花费的时间更少。UUS技术在水中表现为正向、反向、侧向的蝶泳打腿，同时也包括在泳姿转换时的运用。 目前，美国在该项技术的研究和应用上处于领先地位，这是他们在游泳界的突出优势。中国在UUS技术的应用上还有待进一步学习和提高。本文从理论上介绍了鱼类摆尾技术的流体力学研究成果，并在实践中与运动员蝶泳腿技术分析相结合，指出水下蝶泳打腿技术的运动学、动力学特征以及在游泳出发、转身和划水过程中的应用。水下蝶泳腿技术是游泳项目中的一项重要技术，我们应该学习国外的理论成果，重视实践经验的积累，努力提高中国游泳队的技术水平。 关键词:游泳技术,水下蝶泳打腿 Abstract: Underwater Undulatory Swimming, referred to UUS, is a very effective swimming skills. Acceptance of the underwater butterfly kick technical training athletes than those who do not have to take the technology players in the starting stage and turned the time it takes even less. UUS technical performance in the water for the positive, reverse, lateral butterfly kick, but also included in the conversion of the use of strokes. At present, the United States in the technology research and application on a leading position in which they are prominent in the swimming community advantages. UUS Chinese in the application of technology to be further study and improve. In this paper, a theoretical introduction of fish before the end of technology, fluid mechanics research and in practice with the athletes butterfly leg of technical analysis, pointed out that the butterfly kick underwater technology, kinematics, dynamics features, as well as in swimming, the turning and the water in the process of application. Butterfly leg of underwater swimming technique is an important technology, we should study abroad, theoretical results, the accumulation of great importance to practical experience, and strive to improve the technological level of Chinese swimmers. Key words: swimming; underwater undulatory swimming; technique 引 言 2008年北京奥运会上，美国队在游泳比赛中取得了非常优异的成绩，尤其是菲尔普斯连得了八枚游泳金牌。赛后，记者问他是否有什么取胜的秘诀，?菲尔普斯笑着透露：“我的教练一再嘱咐我，一定要注意转身后的水下打腿技术，这招果然灵验！要知道，无论是自由泳、蝶泳还有混合泳，都有水下打腿的技术！”水下蝶泳打腿技术，即Underwater Undulatory Swimming，简称:UUS，是一套非常有效的游泳技术。接受水下蝶泳打腿技术训练的运动员要比那些没有采取此项技术的选手
