Peaty, who has dominated the breaststroke event for almost a decade, won gold in the 100m at the 2021 Tokyo Games, becoming the first British swimmer to hold an Olympic title.
He missed the 2022 World Championships due to a foot injury and sat out last year as he took time away from the sport to prioritize his mental health.
The world record holder told the BBC last week that he had overcome difficulties and arrived in Doha “peacefully”.
While some top swimmers are skipping the championships to focus on the 2024 Paris Games, Peaty will use the event as part of his preparations for a third consecutive 100m gold medal at this summer's Olympics in the French capital. ing.
Peaty, who reached the semi-finals with the third fastest heat, improved his time to become the fastest qualifying heat, ahead of American Nick Fink (58.73 seconds) and Dutchman Arno Camminga (58.87 seconds). He became a passer-by.
“I feel good,” Peaty said after clinching a spot in the final. “My goal for this competition is to advance through the rounds and progress not only physically and in results, but also mentally, to see what strategies are working and what aren't. That was it.
“This is something of a test event for us, but obviously we're going to do our best and put up a good fight.
“After the heat, I was like, ‘Okay, I know what I’m working on, I know what I’m capable of.’ But tonight, we showed a little bit of Adam Peaty, our forward line. I almost went out.''At the end, I was a little mad at myself, as usual.Tonight, I showed that I can still figure it out on the back end when I really need to.''
Fellow Briton James Wilby competed in the heat.
