Does chasing your kids leave you panting for breath? That’s because they’re as fit as professional athletes, according to a new study.

　　追逐你的孩子会累得你气喘吁吁吗?一项新的研究表明，那是因为他们和专业运动员一样健康。

　　Researchers from Edith Cowan University in Australia and Université Clermont Auvergne in France studied energy use and post-exercise recovery in groups of 8- to 12-year-old boys, trained adult athletes and untrained adults. They had all three groups perform a series of high-intensity physical activities, and found that kids outperformed the adults.

　　来自澳大利亚埃迪斯科文大学和法国克莱蒙奥弗涅大学的研究人员对8到12岁的男孩、经过训练的成年运动员和未经训练的成年人进行了分组研究，研究他们能量消耗和运动后恢复的情况。他们让三组人进行一系列高强度的体育活动，结果发现孩子们表现得比成年人好。

　　“We found the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities,” study author and exercise physiologist Sébastien Ratel writes in a press release. “They also recovered very quickly — even faster than the well-trained adult endurance athletes.?.?. This may explain why children seem to have the ability to play and play and play, long after adults have become tired.”

　　该研究的作者、运动生理学家塞巴斯蒂安.拉泰尔在一份新闻稿中写道:“我们发现，孩子们更多地使用了有氧代谢，因此在高强度的体育活动中，他们就没那么疲劳了。他们也恢复得很快—甚至比训练有素的成年耐力运动员还要快……这也许解释了为什么成年人累了后，孩子们似乎还有精力可以一直玩很久。”

　　These findings could help parents who want to develop their kids’ athleticism.

　　这些发现可以帮助那些想要培养孩子运动能力的父母。

　　“Our study shows that muscle endurance is often very good in children, so it might be better to focus on other areas of fitness such as their sports technique, sprint speed or muscle strength,” Ratel writes. “This may help to optimize physical training in children, so that they perform better and enjoy sports more.”

　　拉泰尔写道:“我们的研究显示，儿童的肌肉耐力通常很好，所以最好关注其他健身领域，比如他们的运动技巧、冲刺速度或肌肉力量。这可能有助于优化孩子的体能训练，使他们表现得更好，更享受运动。”
