今天整理的是蝶泳butterfly。蝶泳也叫海豚泳,这是很形象的叫法,手臂的展翅飞翔像蝴蝶,body的波浪打水像海豚。人类的四肢要像流线型的海豚和翅膀型的蝴蝶那样自由自在有多么的难,所以蝶泳成了四种泳姿里最难学的一种,也是最美最有力度的一种,用英语来说,Butterfly is the most respectful swimming style because of its power and beauty.
蝶泳要强调的就是timing and rhythm以及core muscles的运用。什么是core? "Core" actually consists of many different muscles that stabilize the spine and pelvis骨盆, and run the entire length of the torso躯干.
