At the 2010 FINA Short Course World Championships in Dubai, Lochte became the first individual in history to win seven medals at the Short Course Worlds and was the only person to set a world record individually since body-length swimsuits were banned. In Dubai, Lochte won gold in the 200-meter backstroke, 200-meter freestyle, all individual medleys (100, 200, 400), and 4×100-meter medley relay. He also won silver in the 4×200-meter freestyle relay. Lochte's world records in Dubai came on consecutive days, first in the 400-meter individual medley, then in the 200-meter individual medley. Both world records were broken by considerable margins.
