Alvarez received medical attention before being taken away on a stretcher, according to the Olympic Games website.
In a statement shared on the US’s Artistic Swimming Instagram page, Fuentes said: “Anita is okay” following the harrowing incident.
“The doctors have checked all vital signs and everything is normal: heart rate, oxygen, sugar levels, blood pressure, etc…everything is fine,” she said.
“We sometimes forget that this happens in other endurance sports. Marathon, cycling, cross country,” she continued. “We’ve all seen images where some athletes don’t make it to the finish and others help them get there.”
“Our sport is no different from others, only in a pool we push boundaries and sometimes we find them,” she said. “Anita is feeling well now and the doctors also say she is fine.”
In an interview with the Spanish newspaper Marca, Fuentes said she jumped in the water “because I saw no one, not a lifeguard, dive in.”
“I got a little scared because she wasn’t breathing, but now she’s okay,” she said
