The Downward breaststroke kick makes fast speed and increased lactate acid
In this study, we assess the effectiveness of utilizing a downward breaststroke kick with regard to the overall time, max speed and velocity per stroke when using a downward breaststroke kick technique. We analyzed breaststroke kick of knee angles from 8 elite world class swimmers. The downward breaststroke kick used in breaststroke competitions resulted in improvements average of 100 yard or 100 meter breaststroke from 1:05.10 s to 1:01.97 s. Increases in performance max speed and velocity per stroke among 9 elite world class swimmers are highly correlated to duration of the kick aerodynamic buoyant farce in breaststroke. The downward breaststroke kick also resulted in an increase in lactate acid
