There is an immediate rule change in the breaststroke:
“101.2.3 Kick — After the start and after each turn, at any time prior to the first breaststroke kick, a single butterfly (dolphin) kick is permitted, following which, all movements of the legs shall be simultaneous and in the same horizontal plane without alternating movement. The feet must be turned outwards during the propulsive part of the kick. Scissors, alternating movements, or downward butterfly (dolphin) kicks are not permitted except as provided herein. Breaking the surface of the water with the feet is allowed unless followed by a downward butterfly (dolphin) kick.”
