Butterfly stroke 蝶泳
While other styles like the breaststroke, front crawl, or backstroke can be swum easily even by beginners, the butterfly is a more difficult stroke that requires good technique to be feasible. It is the newest swimming style swum in competition, first swum in 1933. Interstingly, the butterfly kick was developed separately, and is also known as the "dolphin kick".
初學者也許能很容易地掌握蛙泳、自由泳或仰泳,但蝶泳卻難得多,對游泳者的技術要求很高。蝶泳出現于1933年,是競技游泳的幾種泳姿中最新的一種。有趣的是,蝶泳的踢水動作是單獨發展出來的,而且被叫做“海豚踢”。
