Australian Kyle Chalmers broke the 13-year-old men’s 100m freestyle short-course world record this morning (AEDT) in Kazan, Russia.
The Australian touched in 44.84sec to take 0.10sec off the record set by Frenchman Amaury Leveaux in 2008.
Chalmers took silver in the event in the longer 50m Olympic pool in Tokyo finishing 0.06sec behind American Caeleb Dressel who won in 47.02.
The 23-year-old Aussie also won two relay bronze medals in Tokyo.
Chalmers had won the 100m in the three previous legs of the four-event World Cup this month.
The competition is swum in 25m pools where times are traditionally faster.
Leveaux set his world record in the European short-course championships in Croatia in December 2008.
It was the third time the record had been broken in a week.
Leveaux beat the time he had set the day before when he had topped the six-day-old mark of compatriot Alain Bernard.
