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.
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.
Backstroke performances (only) are eligible for backstroke records, as they are performed under normal controlled starting conditions (i.e., reflex latency for the starting gun makes the average split time marginally quicker); for example, Ryan Murphy set the world record for the 100 m backstroke during the first leg of the 4 × 100 m medley ...
The dolphin kick gained prominence during the 1988 Olympics, where several competitors used the dolphin kick extensively at their starts in the 100m backstroke final. In response, the FINA limited the use of the dolphin kick to 15 meters.

Only skeletal and smooth muscles are part of the musculoskeletal system and only the muscles can move the body. Cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these muscles are not under conscious control. Skeletal muscles are attached to bones and arranged in opposing groups around joints. [8]
