Ruta Meilutyte of Lithuania set her second world record in as many days in the women's 50 meters breaststroke, powering to the gold medal in a time of 29.16 seconds at the World Aquatics Championships in Fukuoka yesterday.
She obliterated the record of 29.30 seconds she had held jointly with Benedetta Pilato of Italy after setting that mark in her semi-final on Saturday.
She was 0.78 seconds ahead of silver medalist Lilly King of the United States. Pilato took bronze in 30.04.
Sweden's Sarah Sjoestroem had broken her own world record in the women's 50m freestyle semi-finals in 23.61 seconds a day earlier, and the 29-year-old was almost as quick in the final to claim gold.
Sjoestroem finished only one hundredth of a second slower than her record feat to beat Australia's Shayna Jack, who clocked 24.10, in the final. Zhang Yufei took bronze for China in 24.15.
Ahmed Hafnaoui ensured a second gold of the meeting for Tunisia after edging past Bobby Finke of the United States in a fiercely contested 1,500m freestyle race.
He finished in 14 minutes 31.54 to miss out on Sun Yang's world record of 14:31.02. Finke was a mere 0.05 seconds behind the champion while Australia's Sam Short settled for bronze.
American Hunter Armstrong bagged the men's 50m backstroke title to secure his first individual crown while Canada's world record-holder Summer McIntosh proved too good for the field in the women's 400m individual medley.
