DOHA, Qatar — Five more world records were broken at the short-course world championships on Sunday, with Sarah Sjostrom of Sweden setting two on the final day.
The total number of world records at the Hamad Aquatic Centre in Doha ended at 23, way ahead of the 17 set at the 2008 worlds in Manchester.
Sjostrom dominated her events in the 25-meter pool, setting records in winning the 100-meter butterfly and 200 freestyle finals.
Etiene Medeiros of Brazil became the fastest woman to swim the 50 backstroke, Markus Deibler set a new mark in winning the 100 medley and the Netherlands broke the record in the women's 4x50 freestyle.
In her first race, Sjostrom cruised to victory in 54.61 seconds, breaking Diane Bui Duyet's mark of 55.05 set in 2009. China's Ying Lu (55.25) and Denmark's Jeanette Ottesen (55.32) took silver and bronze.
In the 200 freestyle, Sjostrom came back with enough energy to touch just ahead of Katinka Hosszu, finishing in 1:50.78. She broke the previous mark of 1:51.17, set by Federica Pellegrini of Italy.
Hosszu was 0.01 seconds behind, while Femke Heemskerk of the Netherlands took bronze in 1:51.69.
Also, Medeiros became the first Brazilian woman to win an individual goal at the short-course worlds. She finished in 25.67 to shave 0.03 off Croatian Sanja Jovanovic's time set in Istanbul in 2009. Emily Seebohm of Australia came second in 25.83, and Hosszu was third in 25.96. Hosszu finished the meet with four golds, three silvers and two bronze medals.
Deibler of Germany bettered American star Ryan Lochte's record in the 100 medley. Deibler finished in 50.66, slicing 0.05 seconds off Lochte's effort in Istanbul in 2012.
Lochte took bronze this time in 51.24, behind Russian Vladimir Morozov's 50.81.
The Dutch women had opened the night with a record, improving on the mark they had set hours earlier in the heats.
Ranomi Kromowidjojo, Inge Dekker, Femke Heemskerk and Maud van der Meer combined to finish in 1:34.24, erasing 1.50 off of their morning effort.
The United States, which led for most part of the race before Kromowidjojo went ahead, took silver in 1:34.61. Denmark took bronze in 1:35.48.
Chad le Clos justified his world swimmer of the year status as he swept the butterfly events at the meet. On Sunday, the South African picked up his fourth gold, winning the 200 butterfly after a close fight with Japan's Daiya Seto.
Le Clos clocked 1:48.61, ahead of Seto's 1:48.92. Pawel Korzeniowski of Poland was third with 1:50.21.
The Brazilian men enjoyed a great night as well, winning three golds. Cesar Cielo edged Florent Manaudou in the 100 freestyle, while Felipe Franca Silva won the 50 breastroke. Brazil later also came first in the 4x100 medley relay.
Manaudou was the favorite going into the final, but Cielo surprised by touching home in 45.75, beating the Frenchman by 0.06. The bronze went to Russia's Danila Izotov in 46.09.
Radoslaw Kawecki of Poland surprised the field to win the 200 backstroke. The other gold medalists on the final night were Kromowidjojo (50 freestyle), Kanako Watanabe of Japan (200 breaststroke), Gregorio Paltrinieri of Italy (1,500 freestyle) and Denmark (women's 4x100 medley relay)
