“水下蝶泳打腿技术”的生物力学特征及发展途径相关问题的研究

The Research on Biomechanical Traits and Training Methods of the "Underwater Butterfly Kick"

利用近些年国内外对"水下蝶泳打腿技术"的研究资料,从生物力学的角度进行总结和分析,结果显示:"水下蝶泳打腿技术"与水面游进相比,具有攻角小与波浪阻力小的优势,技术特点表现为振幅小频率快,要求运动员有很好的脚踝柔韧性和较强的腰腹及腿部力量。

Taking advantage of dissertations on ＂underwater butterfly kick＂ in China and from abroad, this article summerizes and analyzes relevant data from biomechanical perspective, and concludes： The ＂underwater butterfly kick＂ has the relative merits, compared to emersed kick, of having smaller angle of attack and wave resistance. The characteristic of the technique is its small amplitude and low frequency, requiring athletes to possess flexible ankle joints, and powerful waist, abdomen,and leg strength. The paper also discusses how to develop these qualities and master the principle and methods of this underwater skill.
