Samantha Cerio was competing for Auburn University in the regional finals of the 2019 Gymnastics Championships in America when she attempted a handspring double front in her floor routine.
Cerio sprinted into the approach and looked in good shape to land the complicated manoeuvre.
But, as the shocking footage shows, her legs collapsed on impact and she is left writing on the floor in pain.
The crowd can be heard gasping as a doctor rushes to her side, where they find the stricken gymnast having dislocated both knees and broken both of her legs.
A commentator on the action is heard on TV saying: “I think she may be hurt.” They then add: “It looked like that ankle came down very awkwardly and she is obviously in some pain.”
The camera then cut away from the action.
Doctors rushed to Cerio’s aid and she was stretchered out of the arena with air costs on both of her legs. The crowd stood to applaud as she was taken from the floor.
The injury is so severe that Cerio has decided to quit gymnastics for good.
“After 18 years I am hanging up my grips and leaving the chalk behind,” Cerio posted on Instagram after the shocking fall, which was caught on camera.
“I couldn’t be prouder of the person that gymnastics has made me to become.
“It’s taught me hard work, humility, integrity, and dedication, just to name a few.
“It’s given me challenges and road blocks that I would have never imagined that has tested who I am as a person.
“It may not have ended the way I had planned, but nothing ever goes as planned.”
Auburn coach Jeff Graba revealed that he had never seen an injury as severe as Cerio’s, and praised the athlete for her bravery.
He said: “It was pretty tough to watch.
“She’s a trooper. The last thing she said was, ‘Go help the girls.’ The girls rallied around her. They’re doing this for her right now.”
“I gave her a hug, told her I hugged her before she left and said we’d catch back up tonight.”
Away from gymnastics, Cerio has previously been named SEC co-scholar athlete of the year and she will graduate this year with an aerospace engineering degree.
She is also getting married in Alabama in June and will then head to Seattle to begin working for Boeing.
