"Obviously there's 300-pound men on the line but it's sort of like taking a penalty shot: you're not worried about the keeper, you're worried about just putting the ball in the back of the net," Lloyd, co-captain of the United States team that won the soccer World Cup in July, told Reuters.

"You're focused on the technique, you're focused on getting the ball up and over and in between the uprights, your focus isn't necessarily on the people in front of you."

The 37-year-old forward said she had successfully practised in pads and a helmet, focusing on repetition and technique.

She sparked intense interest in August when a video of her kicking a 55-yard field goal at a Philadelphia Eagles practice went viral on the internet.

Lloyd said a fourth trip to the Olympics, in Tokyo next year, was her top priority but the timing of the Games would allow her to also try to realise her hopes of becoming the first woman to be drafted to an NFL team.

Lauren Silberman became the first woman to enter the NFL combine in 2013, after the league announced that it would allow women to participate from 2012, but the would-be kicker was not drafted.

Lloyd's interest coincides with a decline in performance among kickers, with Dallas Cowboys' Brett Maher the most recent player to get cut after missing 10 field goal chances this season.
