A youngster from Patchogue is one of the top young athletes in ninja warrior competitions.

If you’ve seen the TV show “American Ninja Warrior,” you have an idea of what a competition entails: completing various tasks along an obstacle course as fast as you can while making as few mistakes as possible.

It turns out that swinging from rings and scooting across balance beams are things 10-year-old Ananyssa Truong is really good at.

The rising sixth grader recently finished first in her age group at the World Ninja League Northeast Regional Championships in Hainesport, N.J., recently. She completed the flow course in 44.5 seconds and the challenge course in 1:48, which qualified her to compete June 21-24 in the World Ninja League Championships in Greensboro, N.C., where she’ll be competing before thousands of people.

The sport has grown in popularity, thanks to the TV show “American Ninja Warrior” on NBC, in which contestants compete for a $1 million prize. That’s how Ananyssa learned about the sport.

“I said, ‘I really want to do this,’” she said.

Ananyssa took up ninja competitions about a year and a half ago, and her progress has been nothing short of amazing, her father Hung Truong said. She finished 33rd out of 33 contestants at last year’s Northeast Regionals and competed just to get some experience.

“Last year I was really nervous, but this year I felt a lot more confident,” Ananyssa said.

Her father marvels at how much Ananyssa has improved since last year.

“Her growth in one year has been phenomenal.” he said. “We’ve stressed that it’s not about the performance. It’s about the progress.”

Ananyssa trains at a gym in Roslyn three times a week. She competes in competitions most weekends. She’ll be competing at the Ultimate Ninja Athlete Association World Series Finals in Anaheim, Calif., in July and the OCR World Championships in Costa Rica in August.

Ananyssa said her friends think it’s “really cool that I can do this.”

She tells them the lesson is to “train as hard as you can and do your best.”
