Asher-Smith’s experiences in Munich two years ago led the former 200m world champion to call for more research into the effect of periods on performance, after her 100m title defence was ruined mid-race by calf cramps caused by her cycle.
She bounced back from that setback to win 200m silver but, following a disappointing World Championships last summer where she finished eighth in the 100m final and seventh in the 200m, Asher-Smith split with long-time coach John Blackie in October, ending a 19-year partnership.
Having now moved to train with Edrick Floreal in Austin, Texas, this was a timely victory for Asher-Smith as she builds towards an attempt at winning her first individual Olympic medal at Paris 2024.
She was able to deliver in the final after producing a statement 10.97secs in her semi-final – the fastest time by a European woman this year.
Asher-Smith told BBC Sport: “I’m in a great place but, when you’ve got a few new things to get your head round, sometimes it does take a little bit of time.
“Overall I’m really happy that I’m six to eight months into a new set-up and I’m here putting together performances like this back to back.”
On the Olympics, she added: “I’m very excited. I think a European Olympics is going to be so much fun and, if I am being honest, my mentality this year is just chill out and have a great time.”
Team-mate Amy Hunt, 22, finished seventh in the final in 11.15secs.
