主　　题：Swimming Breaststroke Downward Kick Lactate Acid Olympian 

摘      要：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 *** analyzed breaststroke kick of knee angles from 8 elite world class *** 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 *** 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 *** downward breaststroke kick also resulted in an increase in lactate acid.
