By TARA PARKER-POPE c.2008 New York Times News Service Young children spend an extraordinary amount of time moving about: an average of three hours a day at age 9, new research shows. 아이들이 어렸을 때는 이리저리 움직이고 다니는 데 엄청난 시간을 소비한다: 새로 나온 연구결과는 9세 때 움직이는 시간이 하루 평균 3 시간이나 된다는 것을 보여주고 있다. But in just a few short years, all that childhood energy disappears. By the age of 15, daily physical activity is down to just 49 minutes on weekdays and about a half-hour on weekends, according to the research, being published Wednesday in The Journal of the American Medical Association. 그러나 그 후 불과 2-3 년이 지나면 어린이의 이러한 왕성한 정력이 살아져 버린다. 15 세에 이르면, 하루에 신체 활동을 하는 시간이 평일에는 불과 49 분으로 줄고 주말에는 약 반 시간으로 준다. 이 연구 결과는 16일 JAMA(the Journal of the American Medical Association)에 발표된다. Experts have long believed that activity wanes as children enter their teenage years. This study affirming that belief, one of the largest and longest ever undertaken on the subject, followed about 1,000 children from around the country and, unlike many previous studies, used monitoring devices to track the activity carefully rather than relying on reports from parents. 전문가들은 어린이들이 10대가 되면서 신체 활동이 감소된다고 생각한 지 오래 되었다. 그러한 생각을 반증해주고 있는 이 연구는 이 주제에 관한 연구로는 가장 규모가 크고 장기간에 걸친 것 중의 하나였으며, 미국 각 지방을 대상으로 약 천 명의 어린이들을 따라다녔다. 과거의 여러 연구들과는 달리 이 연구에서는 부모들의 보고에 의존하는 것이 아니라 신체 활동을 예의 추적하는 모니터 장치가 사용되었다. The findings, which measured everything from moderate walking to vigorous athletic pursuits, show clearly that even the most energetic young children experience a precipitous drop in physical activity as they reach puberty. "I was surprised by the degree of the drop; it's a dramatic shift," said the lead author, Dr. Philip R. Nader, emeritus professor of pediatrics at the University of California, San Diego. "Younger children appear to be naturally active, but as kids get older, they find fewer opportunities to be active." The research was part of the continuing Study of Early Child Care and Youth Development, a look at the health of American children that was begun in 1991 and is financed by the National Institutes of Health. The authors had the children wear accelerometers, devices that measure movement, for a week at each of four ages: 9, 11, 12 and 15. Overall, boys were more active than girls, moving an average of 18 more minutes a day. Age 13 appeared to be a particularly vulnerable time. Though activity was not measured at that age, mathematical modeling showed it was at that point that daily weekend activity, for boys and girls alike, dropped below 60 minutes. The study did not measure reasons for the decline, but researchers noted that schools often curtail physical activity as children get older. Not only does recess stop, but many schools drop physical education as well. In addition, sports become more exclusive as children grow, allowing only the best athletes to compete.
