Prior to September 1992 swimmers had to touch the wall on their back before initiating the turn or rolling off their back in order to turn. After September 1992 when approaching the wall, the swimmer is allowed to turn to their breast and make one push/pull phase with one arm or simultaneous double arm pull. Next, the swimmer makes half a tumble turn forward, resting the feet against the wall. The arms are in the forward position at this time, and the swimmer pushes their body off the wall. Similar to the start, the swimmer can remain up to 15 m under water, with most swimmers using a butterfly kick for speed. This rule change allowed for faster turns.
