The legs perform a flutter kick. Elementary backstroke: Both arms move synchronized (They begin out like an airplane, then go beside the body like a soldier then they run up the sides and back out to an airplane position) with whip kick. Inverted butterfly: Similar to elementary backstroke, but with a dolphin kick. This is often used for training.
This elementary backstroke swim was used in the 1900 and 1908 Olympics. The backcrawl swim supplanted the elementary backstroke swim after 1908 as the competitive back swim and it is now referred to as the backstroke. Another variant is the old style of swimming backstroke, where the arm movement formed a complete circle in a windmill type pattern.
The flutter kick in a front crawl. In swimming strokes such as the front crawl or backstroke, the primary purpose of the flutter kick in beginner and intermediate swimmers is not propulsion but keeping the legs up and in the shadow for the upper body and assisting body rotation for arm strokes.
It is one of two long axis strokes, the other one being the backstroke. Unlike the backstroke, the breaststroke, and the butterfly stroke, the front crawl is not regulated by World Aquatics. Hence, in "freestyle" competitive swimming events, any stroke or combination of strokes is permissible.
Streamline position is the basis of the spinal axis strokes, backstroke and freestyle, as well. A swimmer will try to maintain a straight back and legs to minimize 'drag' during the stroke. The Fédération Internationale de Natation (F.I.N.A.), otherwise known as the International Swimming Federation , has strict rules on how and when ...
Flutter kick is suitable for long distances at moderate speeds, and long elastic blades are more efficient for converting power into thrust. Flutter kick is the alternating up and down motion of the legs, either from the hips or as the more restricted movement of the modified flutter kick, and is the most frequently used finning technique.

The front crawl is most commonly chosen by swimmers, as this provides the greatest speed. During a race, the competitor circles the arms forward in alternation, kicking the feet up and down (flutter kick). Individual freestyle events can also be swum using one of the officially regulated strokes (breaststroke, butterfly, or backstroke).
Prior to Berkoff's innovation, many or most backstroke and freestyle swimmers used the flutter kick during the underwater phase of their starts and turns. In 1991, and remaining as of 2022, the distance limit increased to 15 meters at the start and after the turns for backstrokers, butterfly and freestyle swimmers.
