101.2 BREASTSTROKE
.1 Start — The forward start shall be used.
.2 Stroke — After the start and after each turn when the swimmer leaves the wall, the body shall be kept on the breast. It is not permitted to roll onto the back at any time except at the turn after the touch of the wall where it is permissible to turn in any manner as long as the body is on the breast when leaving the wall. Throughout the race the stroke cycle must be one arm stroke and one leg kick in that order.
All movements of the arms shall be simultaneous and in the same horizontal plane without alternating movement.
The hands shall be pushed forward together from the breast on, under, or over the water. The elbows shall be under water except for the final stroke before the turn, during the turn and for the final stroke at the finish. The hands shall be brought back on or under the surface of the water. The hands shall not be brought back beyond the hip line, except during the first stroke after the start and each turn.
During each complete cycle, some part of the swimmer’s head shall break the surface of the water. After the start and after each turn, the swimmer may take one arm stroke completely back to the legs. The head must break the surface of the water before the hands turn inward at the widest part of the second stroke.
.3 Kick — After the start and each turn, a single butterfly kick, which must be followed by a breaststroke kick, is permitted during or at the completion of the first arm pull. 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 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 kick.
.4 Turns and Finish — At each turn and at the finish of the race, the touch shall be made with both hands separated and simultaneously at, above, or below the water level [effective September 23, 2013]. At the last stroke before the turn and at the finish an arm stroke not followed by a leg kick is permitted. The head may be submerged after the last arm pull prior to the touch, provided it breaks the surface of the water at some point during the last complete or incomplete cycle preceding the touch.
