(CNN) -- Eight-time gold medal winner at the Beijing Olympics and multiple world-record holder Michael Phelps warmed up for the Swimming World Championships in Rome by setting a new men's world record in the 100 meters butterfly.

Michael Phelps attacks the pool in Indianapolis to set a new world mark in the 100m fly.

The 24-year-old American shaved 18-hundredths of a second from the previous mark set by compatriot Ian Crocker in 2005, with a time of 50.22 on the third day of competition at the U.S. National Championships in the Indianapolis.

"I was pretty happy with my swim. I really wanted to break 50 seconds, but that is something to shoot for," Phelps told the event's official Web site.
