The United States dominated the International Federation of American Football (IFAF) Americas Continental Flag Football Championships as the country won both gold medals.

The men's tournament was decided by a high-scoring thriller at the University of North Carolina in Charlotte.

The lead changed hands 10 times with the contest settled by Laderrick Smith's bullet pass to find Laval Davis in the end zone to make the score 40-36.

"It's what we expected from Mexico," said America's Darrell Doucette.

"We knew they could score a lot of points and we felt like our defence should be able to at least stop them a few times.

"The captain of the defensive team just said try to score more points than them.

"They stopped them at the end of the game and we were able to nail it out and we got a gold medal."

Flag football is a variant of American football where, instead of tackling players to the ground, the defensive team must remove a flag or flag belt from the ball carrier to end a down.

Panama claimed third place following a 38-22 victory over Canada in the bronze medal-match, while Argentina, Chile, and Brazil finished fifth, sixth, and seventh, respectively.

America's women then emulated their compatriots' success with a 26-21 triumph against Mexico.

The teams were inseparable as they traded scores and stops until Amber Clark clinched the win with a last-minute interception.

Competing in her home state, wide receiver Madison Fulford starred in attack for the US as she reeled in four touchdown catches from quarterback Vanita Krouch.

"It's especially rewarding but we've prepared for this," said Fulford.

"It feels really good to have this win.

"Vanita made really good decisions with really good reads and we came together as a team and our defence really stepped up."

Panama were unable to win another bronze medal as Canada got the better of them this time in a tense finish. 

The teams were level 14-14 at the end of regulation time but the Canadians eventually pulled away to win 20-16.

Brazil then claimed fifth place overall with a 34-6 result against Chile.
