The previous world record for the 97 pound division was 209 pounds broken by a 44 year old European woman last summer.
The Guinness world record for the most weight squat lifted in one hour by an individual is 56,728.53 kg (125,065 lb) by Ryan Lapadat (Canada) at Goodlife Fitness in Guelph, Ontario, Canada.
Guinness World Records also recognized the world record for the most weight lifted by lateral raises in one hour: 19,600 kg (43,210 lb) by Eamonn Keane (Ireland) at Louisburgh Gym in Louisburgh, Ireland.
Kutin actually regained her own world record after losing it several months ago. Kutin, who began powerlifting in April 2010, first set the 97-pound world record last July at age 9, but Geitner bested it with a 209-pound squat last September.
Kutin drew a round of applause from the onlookers as she completed the record-breaking lift.
The event, an invitational for elite powerlifters, had never invited a competitor younger than 14, but made an exception for Kutin because of her extraordinary achievements to date, her father Ed said.
"When I was younger, my friends would be doing a lot of things that I couldn't do, and I wanted to do something extraordinary," an excited Kutin said. "I wanted to break a record of some sort and I just really wanted to get this record."
"You know she gets giggly or silly in a 10-year-old girl kind of way," Naomi's Dad said.
"She's also learned a lot about psyche. In this sport, it's not just about strength, it's also about the ability to focus and psyche, and she's back there pacing and getting herself psyched and she's really doing that well too."
