小菲的教练说：
Number
one, you need to really work on the kick, particularly the underwater kick.
That’s the very best way you’ve got to use your momentum, and it helps maintain
your rhythm in the regular stroke… The kick’s power originates from the chest,
and the whole body is part of the
motion.
首先，你必须下苦功夫练习打海豚腿，尤其是水下海豚腿。游蝶泳打好海豚腿就会将你身体的能量（动量），通过这种最好的方式体现出来：通过有规律律动的海豚打腿，来保持你身体的良好的节奏感。海豚腿的发力起点是从胸部开始的，而运动的核心部分就是整个身体的躯干。
关于蝶泳的发力点,”Kick’s
Power originates from the chest.”Bowman
said.
