SW 5 FREESTYLE 

SW 5.1 Freestyle means that in an event so designated the swimmer may swim any style, except that in individual medley or medley relay events, freestyle means any style other than backstroke, breaststroke or butterfly. 

SW 5.2 Some part of the swimmer must touch the wall upon completion of each length and at the finish. 

SW 5.3 Some part of the swimmer must break the surface of the water throughout the race, except it shall be permissible for the swimmer to be completely submerged during the turn and for a distance of not more than 15 metres after the start and each turn. By that point, the head must have broken the surface. 

SW 6 BACKSTROKE 

SW 6.1 Prior to the starting signal, the swimmers shall line up in the water facing the starting end, with both hands holding the starting grips. Standing in or on the gutter or bending the toes over the lip of the gutter is prohibited. When using a backstroke ledge at the start, at least one toe of each foot must be in contact with the end wall or face of the touchpad. Bending the toes over the top of the touchpad is prohibited. 

SW 6.2 At the signal for starting and after turning the swimmer shall push off and swim upon his back throughout the race except when executing a turn as set forth in SW 6.4. The normal position on the back can include a roll movement of the body up to, but not including 90 degrees from horizontal. The position of the head is not relevant. 

SW 6.3 Some part of the swimmer must break the surface of the water throughout the race. It is permissible for the swimmer to be completely sub-merged during the turn, and for a distance of not more than 15 metres after the start and each turn. By that point the head must have broken the surface. 

SW 6.4 When executing the turn there must be a touch of the wall with some part of the swimmer’s body. During the turn the shoulders may be turned over the vertical to the breast after which an immediate continuous single arm pull or immediate continuous simultaneous double arm pull may be used to initiate the turn. The swimmer must have returned to the position on the back upon leaving the wall. 

SW 6.5 Upon the finish of the race the swimmer must touch the wall while on the back. 

SW 7 BREASTSTROKE 

SW 7.1 After the start and after each turn, the swimmer may take one arm stroke completely back to the legs during which the swimmer may be submerged. At any time prior to the first Breaststroke kick after the start and after each turn a single butterfly kick is permitted. The head must break the surface of the water before the hands turn inward at the widest part of the second stroke.

SW 7.2 From the beginning of the first arm stroke after the start and after each turn, the body shall be 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. From the start and 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 without alternating movement. 

SW 7.3 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. 

SW 7.4 During each complete cycle, some part of the swimmer’s head must break the surface of the water. All movements of the legs shall be simultaneous without alternating movement. 

SW 7.5 The feet must be turned outwards during the propulsive part of the kick. Alternating movements or downward butterfly kicks are not permitted except as in SW 7.1. Breaking the surface of the water with the feet is allowed unless followed by a downward butterfly kick. 

SW 7.6 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. 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. 

SW 8 BUTTERFLY 

SW 8.1 From the beginning of the first arm stroke after the start and each turn, 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. 

SW 8.2 Both arms shall be brought forward simultaneously over the water and brought backward simultaneously under the water through-out the race, subject to SW 8.5. 

SW 8.3 All up and down movements of the legs must be simultaneous. The legs or the feet need not be on the same level, but they shall not alternate in relation to each other. A breaststroke kicking movement is not permitted. 

SW 8.4 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 surface. 

SW 8.5 At the start and at turns, a swimmer is permitted one or more leg kicks and one arm pull under the water, which must bring him to the surface. It shall be permissible for a swimmer to be completely submerged for a distance of not more than 15 metres after the start and after each turn. By that point, the head must have broken the surface. The swimmer must remain on the surface until the next turn or finish.
