What do Inspectors of Turns and Judges of Stroke do?

Question

Accepted Answer

Under World Aquatics rules: Inspectors of Turns One per lane at each end of the pool, checking the start, every turn and the finish. Jurisdiction at the start end: from the starting signal until the first arm stroke is completed (the second arm stroke in breaststroke). At each turn: from the start of the last arm stroke before the touch until the first arm stroke after the turn is completed (second in breaststroke). At the finish: from the start of the last arm stroke before the touch. In 400, 800 and 1500 m freestyle they count laps, show odd-numbered lap cards at the turning end, and the start-end inspector signals (whistle or bell) when the swimmer has two lengths plus 5 m to go. At the start end they check relay take-offs: the next swimmer's feet must still be on the block when the incoming swimmer touches. They install and remove the backstroke ledge in their lane, set at zero. Judges of Stroke Positioned on each side of the pool, checking that the stroke rules for the event are followed, and helping the Inspectors of Turns at turns and finishes. Make sure the backstroke flags are at 5 m from each end wall before backstroke and medley events. Both report breaches to the Referee.
