Paul Biedermann of Germany broke Grant Hackett's long-standing mark in the 400-metre freestyle in Berlin, one of a slew of world swimming records set Saturday.

The German is now the short-course record holder after covering the distance in 3 minutes 32.77 seconds, more than 1½ seconds faster than one of the most impressive records in recent times.

Australian Hackett's mark of 3:34:58 had stood since July 18, 2002, in Sydney.

Five other records were set during the day.

German Steffen Deibler thrilled the home crowd, breaking his 50-metre butterfly record. Deibler touched in 21.80 seconds, bettering the 22.06 he set in Aachen, Germany, on Oct. 24.

Two other swimmers shaved time off their own short-course world records.

Cameron van der Burgh of South Africa broke his own 50-metre breaststroke record. Van der Burgh clocked 25.25 seconds to improve on the time of 25.43 he swam on Aug. 8 in Pietermaritzburg, South Africa.

Leisel Jones of Australia also broke her own world mark in the 100-metre short-course breaststroke. Jones set a new standard of 1:03.30 seconds. She improved on the time of 1:03.72 she clocked on April 26, 2008, in Canberra.

Biedermann was joined by two other swimmers as new record-holders.

Sergey Fesikov of Russia set a world record in the men's 100-metre short-course medley. He won Saturday's heat in 50.95 seconds to break the mark of Ryan Lochte of the United States, who swam 51.15 in Manchester, England, on April 13, 2008.

Shiho Sakai of Japan broke the 200-metre backstroke mark in 2:00.18. The previous standard was set by Kirsty Coventry of Zimbabwe at the same Manchester meet as the Lochte record.

Michael Phelps continued his string of mixed results. He qualified for the 200-metre butterfly final, squeezing in as the eighth and last swimmer in the heats. The U.S. swimmer, who won eight gold medals at last year's Beijing Olympics, then finished fifth in the final.

Nikolay Skvortsov of Russia won the final in 1:50.58.

Phelps didn't compete in a heat in the 100 medley as scheduled.
