Have you ever wondered why children always seem to have bags of energy and never run out of steam? Researchers have discovered that children have the stamina and levels of recovery of endurance athletes. In fact, scientists say children's muscles recover from "high-intensity exercise" a lot quicker than athletes. A study looked at the performance levels of children when they were cycling, and compared their fitness to that of athletes. Researcher Dr Sebastien Ratel said: "We found the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities. They also recovered very quickly - even faster than the well-trained adult endurance athletes."
The researchers hope that their findings will help scientists better understand how the human body changes with age. It could lead to advances in the fight against diabetes and other diseases. Dr Ratel said the research was particularly important as more children were become less active. He warned: "With the rise in diseases related to physical inactivity, it is helpful to understand the physiological changes with growth that might contribute to the risk of disease." He added that children should maintain their fitness as they grow up and play as much as they could so they remain healthy as adults. He said: "Children seem to have the ability to play and play and play, long after adults have become tired."

参考翻译
你有没有想过为什么孩子们好像有用不完的力气还永远都不会累？研究人员发现孩子们有着和耐力运动员一般的精力和恢复力。事实上，科学家们表示，相较运动员而言，孩子们的肌肉能更快地从高强度训练中恢复。一项研究对孩子们骑车时的性能水平进行观察，并将他们的身体素质与运动员进行比较。研究员Sebastien Ratel博士说道：“我们发现孩子们在高强度体力训练中会进行有氧新陈代谢，因此他们不会感觉疲惫。他们们恢复得也很快—甚至比那些受过良好训练的成年耐力运动员还快。”
研究人员希望他们的发现能够帮助科学家们更好的理解人体如何随着年龄而变化。这或许能帮助对抗糖尿病和其他疾病。Ratel博士说越来越多的孩子们没有那么活跃了，所以这项研究尤为重要。他警告称：“缺乏身体锻炼而引起的疾病越来越多，该研究能够帮助理解成长中的生理变化，或许会增加疾病风险。”他还说道，孩子们应该随着年龄的增长维系他们的体格健康，尽可能多运动，这样他们才能维持成年人般健康体格。他说：“孩子们似乎有着一直玩耍的体能，成年人都累的不行了，他们也不知疲惫。”
