The new International Gymnastics Federation event will run until Sunday (June 30) at the Audi Arena with stars of the future set to impress.

Boys aged between 16 and 17 and girls aged between 14 and 15 are eligible to compete as teams place their sights on next year's Olympics.

In the boys' competition Takeru Kitazono will be a star attraction after winning five gold medals at last year's Summer Youth Olympic Games in Buenos Aires.

He claimed the all-round, floor, parallel bars, rings and horizontal bars titles in Argentina's capital and only missed out on pommel horse.

The Japanese star is the favourite for more success with his home Olympics looming in Tokyo.

Russia have selected Ivan Kuliak and Ivan Gerget who finished first and second respectively in the all-round at their Junior National Championships, while China's junior parallel bars champion Yang Haonan is tipped as another to watch.

Hosts Hungary selected their squad after two qualification events with Buenos Aires 2018 floor silver medallist Krisztián Balazs set to lead their charge.

In the girls' events Russia have picked national junior champion Vladislava Urazova as well as silver medallist Viktoriia Listunova and bronze medallist Elena Gerasimova.

All three were beaten by American Konnor McLain at this year's City of Jesolo Trophy while the United States will also look to national junior silver medallist Kayla DiCello.

Japan have selected Chiaki Hatakeda, the daughter of Olympian Yoshiaki Hatakeda who was a multiple World Championship medallist.

Sixty-three countries will be represented in all with 42 medals up for grabs.

In a move designed to increase the importance of every performance, teams will consist of just three gymnasts per nation and the all-round and team medallists will be decided at the end of qualification.

"I think it's really important and big that they have created this event, because without it, we don't get to see our international competition very much," said Viktor Martinez of Belgium.

"It's great to be able to watch those other athletes. 

"Now we know some of the people who we will be competing against if we move up to the senior level. 

"That little bit more is very useful and will help all our development a lot."
