British sprinter Amy Hunt is among the female athletes to speak out against a controversial sports gambling advert starring actress Sydney Sweeney.

The advert has gone viral online and features American Sweeney naked but covering parts of her body with various pieces of sporting equipment.

It has sparked a strong reaction, with plenty of female athletes criticising its sexualisation of women in sport, and how they are being defined by their appearance rather than their achievements as sportswomen.

In a related development, hunt, who became a four-time European champion earlier this summer, referenced the advert after she ran a season's best 22.10 seconds to finish fourth in the 200m final at the Ultimate Championship in Budapest on Sunday.

"Sydney Sweeney, this is what women in sport look like," Hunt expressed in her post-race interview with BBC Sport.

Referring to Melissa Jefferson-Wooden's winning time of 21.47 seconds, the fourth fastest ever over the distance, she added: "21.4. Muscles. Hard work, blood, sweat, tears. This is a beautiful evening."

Furthermore, american actress Sweeney, 29, starred in the television series Euphoria and her films include Anyone But You and The Housemaid.

The backlash has included numerous other athletes from a range of sports posting videos of themselves competing or training, and describing the frustrations and struggles they have faced throughout their careers.

The trend was started by American gymnast Gracie Kramer, who posted a montage of herself training with the caption, "I don't know what Sydney Sweeney was doing, but this is what women in sport look like."

Additionally, australia's four-time Olympic swimming champion Ariarne Titmus noted: "Not only is it a kick in the face to every woman who has dedicated her life to perfecting her craft, but every woman who enjoys sports for what it really is.

"How do we live in a world where monetising a woman's body and sexualising women's sport is still a thing?"

British cyclist and Olympic champion Sophie Capewell MBE, rugby players Lisa Neumann and Ellie Boatman and Australian water polo Olympian Tilly Kearns also shared their stories.

It is worth noting that "I think it's quite powerful, the amount of women who've come out and remarked something," Capewell told BBC Sport after her post gained attention.

"It's giving a very specific picture of women around sport and I think that's the challenging thing. Why is that the face of the campaign that is associated with sport?

"And that's the way you want to portray a woman, instead of it having, I don't know, an athlete or anything else that's more sport-centric.
