European and international health experts say a new study makes the most convincing case for the benefits of children being active. They say the research may lead to new guidelines saying youngsters aged between 5 and 16 need to be active up to 1.5 hours a day. [2] Experts said the study doesn't mean children need to be on treadmills (跑步机) or in a soccer leagues-they just need to be able to run around and play physically, even for short bursts of time. [3] The study looked at 1,732 9-year-olds and 15-year-olds from Denmark, Estonia and Portugal. Physical activity was observed for four continuous days. Despite differences among the three coun- tries where children were observed, the benefits of physical activity were the same. [4] About 40 percent of those observed were reasonably ac- tive, while the rest were sedentary, researchers said. The study found that the benefits of physical activity applied to all children- not just to obese ( 肥胖的) children normally thought to be at a higher risk. [5] While much attention has been paid to children's bad eat- ing habits,this study calls for equal weight to be placed on activity levels. [6] 'We don't need to be getting kids running on treadmills in the gym.' said Cavil.'We need to encourage kids to play.' One of the study's key findings, he explained, is that it proves the benefit of short bursts of activity, rather than a need for continuous exercises. [7] But _____ perhaps the greatest factor in children's physical activ- ity will be the parents themselves.'It's not just that children should be more active,it's the whole family,' said Weiss.'Parents should be role models.' 1.
