Tom Sietas

Tom Sietas is a German freediver, born on 12 January 1977 in Hamburg, who specialises in static apnea, holding the breath motionless underwater, and dynamic apnea, swimming the greatest distance underwater on one breath. He began freediving in 2000 and has since set many world records and won numerous titles. In August 2004 he became world champion in constant weight and static apnea in Vancouver, and in 2005 he was world champion in dynamic apnea in Renens, Switzerland. He took the static apnea record from the performer David Blaine in 2008, reaching 10 minutes 12 seconds in Athens, and later set records in static apnea on pure oxygen that reached 22 minutes 22 seconds in Changsha in 2012, a mark that Goran Čolak later broke. He also set dynamic no fins records, reaching 213 metres in Hamburg in 2008.
