The United States' Bradley Snyder broke a 30-year-old world record on his way to winning the men’s 100 metres freestyle S11 final here this evening, shortly after competition resumed following a delay due to "technical issues".
Snyder clocked a time of 56.15sec to improve on the previous best mark of 56.67 set by compatriot John Morgan in 1986.
The race, which saw China’s Yang Bozun take silver in 59.51 and Japan’s Keiichi Kimura finish third in 59.63, was the second final to take place following a stoppage of around 50 minutes after the discovery of a problem with the water pump system.
Victory ensured Snyder his third gold medal of the Games, and fourth overall, having also taken top honours in the men’s 50m and 400m freestyle S11 events and finished runner-up in the men’s 100m backstroke S11.
"I have been visualising that moment every day for at least the last year, coming into that wall and hearing that time," said Snyder, who had to settle for silver in the men’s 100m freestyle S11 at London 2012.
"It is true now.
"Finishing this meet with the 100m, with that world record - this is the script we wrote, the one we wanted.
"I have got to be honest, I had some doubts today.
"I was feeling a little worn down, but I wanted it real bad."
Snyder’s world record was one of seven set this evening with the first coming courtesy of Ukraine’s Ievgenii Bogodaiko on his way to victory in the men’s 100m breaststroke SB6.
The 22-year-old clocked a time of 1:18.71 to lower the mark he set back at London 2012 by 1.46 seconds and secure his third gold medal of these Games.
Colombia’s Nelson Crispin Corzo took his second silver of Rio 2016 in 1:21.47, while Germany’s Torben Schmidtke secured the bronze in 1:23.47.
Bogodaiko's team-mates Maksym Krypak and Denys Dubrov were well below the world record as they approached the final stages of the men’s 400m freestyle S10, but it was the former who took top honours in 3:57.71 to shave 5.86 seconds off the previous mark.
Dubrov finished with the silver in 4:00.11, while Canada’s Benoit Huot, a gold medallist in the event at Athens 2004, ended up third in 4:04.63 to claim the 20th Paralympic medal of his career.
After not getting the world record she hoped for in the women’s 100m freestyle S10, Canada’s Aurelie Rivard was more than a body-length under the mark in the women’s 400m freestyle S10.
Her time of 4:29.96 was 2.83 seconds quicker than the previous mark held by France’s defending Paralympic champion Elodie Lorandi, who claimed bronze here in 4:35.49 with Australia’s Monique Murphy second in 4:35.09.
China’s Huang Wenpan registered his fourth world record at Rio 2016, with this one coming in the men’s 200m freestyle S3 in 3:09.04.
Ukraine’s Dmytro Vynohradets came a close second in 3:09.77, while China’s Li Hanhua took bronze in 3:23.10.
Huang’s compatriot Zou Liankang broke the world record in the men’s 50m backstroke S2 to claim the gold in 47.17.
Fellow Chinese Liu Benying Liu was the runner-up in 48.84 and Ukraine’s Serhii Palamarchuk completed the podium in 50.23.
Australia rounded out the evening by winning the women’s 4x100m freestyle relay 34 points in a world-record breaking time of 4:16.65.
The US managed silver in 4:20.10, and China came third in 4:24.22.
