British sprinter Amy Hunt called out Sydney Sweeney after finishing fourth at in the 200 metres final at the Ultimate Athletics Championship in Budapest, saying "this is what women in sport look like."
The Euphoria star has come under fire for her involvement in a promotional campaign for American sports betting site Novig.
She appears almost fully nude in multiple photos and videos, posing with various pieces of sporting equipment.
A number of athletes have condemned the actress' involvement in the campaign, saying it demeans and sexualises women's sport.
Hunt ran a season's best in Sunday's final in Budapest, but it was still not enough for the podium as American sprinter Melissa Jefferson-Wooden claimed victory in a blistering 21.47 seconds.
"That was incredible, to be part of such an incredible race -- Sydney Sweeney, this is what women in sport look like," Hunt said to BBC Sport after the race.
"21.4, muscles, hard work, sweat, blood, tears, a beautiful evening."
Hunt's comments come amid a number of videos on social media, mainly from female athletes, responding to the campaign.
Tilly Hearns, Australian Olympic water polo silver medallist, posted a clip of herself training and at competitions with the caption: "Like what are we doing ... so much worse than I imagined too. Here's some real women sports content."
And four-time Olympic swimming champion Ariarne Titmus said on Instagram: "I can't describe how infuriated I feel when I watch this."
"Not only is it a kick in the face to every woman who had dedicated her life to perfecting her craft, but every women who enjoys sports for what it really is -- teamwork, friendship, dedication, excellent, unity, the list goes on.
"But, how do we live in a world where monetising a woman's body and sexualising women's sport is still a thing?"
American gymnast Gracie Kramer posted a video showing her playing a number of sports including football, golf, and baseball alongside her primary discipline with the caption: "Idk [I don't know] what Sydney Sweeney was doing, but this is what a woman in sports looks like."
The video has garnered over one million likes.
