THE AGE THING
The 2008 gold-medal-winning Chinese women's team was at the center of a controversy when it was accused of having athletes too young by the age rules. Both female and male competitors must turn 16 by Dec. 31.
Many in the gymnastics world believe the U.S. women's team is the country's best since the gold-medal squad of 1996. One of the sport's most recognizable and successful coaches goes a step further. "I think this is the strongest team," says Bela Karolyi, who coached the 1996 team and whose list of champions also includes Nadia Comaneci and Mary Lou Retton. "On the '96 team, there were ups and downs. This is the most even team. The truth is going to come out at the Olympic Games. We are going to be at the top." Not making such a bold prediction is the U.S. national team coordinator, his wife, Marta. But she is excited about the team's makeup — its strength and depth — and its potential to challenge the Russians and Chinese for gold. "For a long time, this team has been in my mind," Marta Karolyi says of a squad that will be led by a pair of 16-year-olds, reigning world all-around champion Jordyn Wieber and Olympic trials all-around winner Gabby Douglas. "I've got a very good feel about this team. It's very young but also very aggressive. We're definitely going for a place on the podium."

The International Gymnastics Federation decided to overhaul the scoring system after controversies at the 2004 Games. The "perfect 10" system — one panel of judges awarded a gymnast a score that could not be higher than 10 —has been replaced by one in which a score is determined by combining the marks awarded by two panels of judges. One panel starts from zero and adds points for required moves and difficulty. A second panel starts from 10 and deducts for execution and artistry. Those scores are added together for the score. Generally, scores above 15 are good; they're the rough equivalent of mid 9s in the old system. Scores above 16 are exceptional.
