      Young athletes from around the world will soon get their chance at Olympic gold. The International

Olympic Committee ( IOC ) voted Thursday to host the first-ever Youth Olympics.

     The Summer Games are planned to stage in August of 2010. The 12-day competition will feature

3,200 kids between the ages of 14 and 18. The Winter Games will be held in 2012 and are expected to

attract 1,000 athletes. Both games will take place every four years.

     Seeing the rise in childhood fatness, IOC president Jacques Rogge said he hopes the competitions will encourage young people to get off the couch and get into shape. Rogge also admitted that the IOC is

looking to pull in a younger television audience to the Olympics.

      In recent years, interest in the games among young people has fallen, with the average age of Olympic viewers on the rise. Rogge admitted that kids today are more interested in flashier( 浮华的 ) athletic

sports like the X Games, which stand for such sports as BMX freestyle, surfing, and Moto X Racing.

      The Olympics have tried to keep up with the competition by adding BMX-cross cycling, ski cross,

and snowboarding to the program. And the IOC is hoping to strengthen its fame among teens by adding

skateboarding in the 2012 London Olympics.

      The Youth Olympics are the IOC's latest attempt to draw the attention of young viewers. "Just as the

IOC has known, over our 100-plus years of living, how to move with the times---so we must now adapt

to meet the taste of today's young generation," he said.
