Brazilian swimmer Cesar Cielo has broken the world record in the 50-meter freestyle, clocking 20.91 seconds on Friday in a meet in Sao Paulo.

The old mark was 20.94 by Frederick Bousquet of France set on April 26 in Montpellier, France.

Cielo also holds the world record for 100 meters of 46.91 seconds, which he set on July 30 in Rome.

The 22-year-old Brazilian won the gold medal in the 50 freestyle at last year's Beijing Olympics.
