Rule for fly kick

I know for masters you can do the frog kick with fly, but can you change from dolphin kick to frog kick in the middle of a 200? Haha. Just worrying that I might not be able to finish it.. What is the usms rule? Does anyone know? Take a look at the the Rule Book, available online under the Articles & Publications tab on the USMS.org home page (http://www.usms.org/rules/). Here's what you asked about: 101.3.3 Kick—All up and down movements of the legs and feet must be simultaneous. The position of the legs or the feet need not be on the same level, but they shall not alternate in relation to each other. The breaststroke or whip kick may be used exclusively or interchangeably with the dolphin kick while doing the butterfly stroke at any time during the race. Only one breaststroke or whip kick is permitted per arm pull, except that a single breaststroke or whip kick is permitted prior to the turn and the finish without an arm pull. After the start and after each turn, a single breaststroke or whip kick is permitted prior to the first arm pull. A scissors kicking movement is not permitted. Enjoy your 200 Fly and Good Luck!
