Figure skating-The famous backflip is set to return at world championships

American figure skater Ilia Malinin was not even born when France's Surya Bonaly thumbed her nose at the International Skating Union's restrictive rules by famously performing a banned backflip at the 1998 Nagano Olympics.

The 20-year-old Malinin and Bonaly's compatriot Adam Siao Him Fa are expected to back-flip into the history books this week as the first skaters in nearly 50 years to land the back somersault - legally - at a world championship.

Malinin, a huge favourite to retain his world men's singles title this week in Boston, became the first to land the high-flying manoeuvre legally in competition since Terry Kubicka of the U.S. at the 1976 Winter Olympics and world championships.

It was banned soon after.

Malinin, the self-proclaimed "Quad God" known for his jaw-dropping athleticism, debuted his backflip in competition at the Lombardia Trophy in September.

The American perfected the backflip as a young gymnast before focusing solely on skating.

"I decided to put it in my free skate, because it fits the music really well," he said. "It gets that audience applause, feels really suspenseful and I really just like doing it."

Germany's twice Olympic champion Katarina Witt is a big fan.

"I think (the backflip) is fun, I think it's great they do this," she recently told Olympics.com. "They sometimes have to go with the flow. Everything is more creative for young people.

"You have those teenagers ... they grew up as a child in a more creative way and I think this already modernised the sport a lot. Now, we're saying, 'just do a backflip.' And
