Rules, rules, rules ....
The RSL follows the same rules for swimming as USA Swimming with the exception of one event, the backstroke turn, which shall be judged using the current Virginia High School League Rules:
"The turn requires that some part of the swimmer's body contact the end wall. After the swimmer's head has passed the backstroke flag, prior to the turn, the swimmer's upper shoulder may (but is not required to) rotate past the vertical toward the breast before the touch is completed; providing such rotation is accompanied by an initiation of the turning action or continuation into the wall."
In other words, the swimmer may, but is not required to, do a flip turn as long as some part of their body touches the wall. For a complete copy of USA Swimming rule book please click here. For a copy of the RSL Rules, please click here.
