We analyzed freestyle kick of knee angles from 7-Olympic medalists, 1970＇s S-shaped pulling pattern stroke was used with a bending knee freestyle kick. The straight knee kick used in butterfly competitions resulted in improvements from 54.74 to 51.00 in Men＇s 100-meter butterfly and fi＇om 23.43 to 23.02 in Men＇s 50-meter butterfly. Using a straight knee kick in backstroke competitions resulted in improvements from 1：01.74 to 1：00.55 in the 100-meter backstroke event. Increases in performance speed, max speed and distance per stroke among three elite level swimmers are highly correlated to duration of the kick resistance, and straight knee kick in backstroke. The straight knee kick also resulted in an increase in lactate acid.展开更多
