Template:Short description Template:Infobox Olympic event Template:Sidebar games events

After finishing fourth in Sydney (2000), Japan's Kosuke Kitajima edged out U.S. swimmer and world-record holder Brendan Hansen to claim the gold medal by 0.17 of a second, in a time of 1:00.08. Katajima used an illegal dolphin kick during a pull-out, however he was not disqualified, and the rules were changed less than a year later to allow for a single dolphin kick after the start and after each wall.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Hansen, who turned 23 on the final day, earned a silver in 1:00.25, while France's Hugues Duboscq held off onrushing American Mark Gangloff to take the bronze in 1:00.88.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
Earlier in the semifinals Hansen lowered an Olympic record to 1:00.01 that had been set by his archrival Kitajima in the preliminaries by just 0.02 of a second.<ref name=100breastsf>Template:Cite news</ref>
