Name a swim stroke that involves a flutter kick.

The front crawl is a swim stroke that prominently features a flutter kick. This technique involves alternating leg movements, where each leg kicks up and down in a rapid motion. The flutter kick supports the body's propulsion and helps maintain a streamlined position in the water, contributing to the efficiency and speed of the stroke. The front crawl is known for its competitive nature in swimming races, primarily because of this effective kicking technique combined with an alternating arm pull.

In contrast, other strokes, such as the breaststroke and sidestroke, utilize different kicking methods, like the frog kick or a scissor kick, which are distinct from the flutter kick. The backstroke does incorporate a flutter kick but is primarily recognized for its unique arm movements and body positioning that differ from the front crawl. Understanding the characteristics of each stroke helps clarify why the front crawl is closely associated with the flutter kick.
