What is the name of the kick in ther freestyle stroke in swimming?
There are just three basic kicks.
Butterfly/Dolphin Kick- Powerful, fluid kick from the hips down,
feet together. This is the only kick allowed in butterfly events,
and is also done during the underwaters (after dives and turns,
before breaking the surface) during freestyle and backstroke events
as well. Doing this kick will disqualify you in a breaststroke
race.
Flutter/Freestyle Kick- Kick in which feet move independently in
rapid flutter motion. This is the kick that you see swimmers do for
freestyle and backstroke events (excluding the underwaters). This
kick will disqualify you if you do it in a breaststroke or
butterfly event.
Breaststroke/Frog Kick- Most technical kick. Beginning with legs
straight and together, knees bend to bring feet up, then legs
separate and feet arc out and down, eventually bringing legs back
together in starting position. The movement is similar to the way
frogs swim, hence it commonly being referred to as 'frog kick.'
This kick is only used for breaststroke, although technically it is
allowed in freestyle (virtually all competitors elect to preform
the much faster flutter kick).
