為什么小孩總是精力充沛 大人卻很容易累?

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

追逐你的孩子會累得你氣喘吁吁嗎?一項新的研究表明，那是因為他們和專業(yè)運動員一樣健康。

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.

來自澳大利亞埃迪斯科文大學和法國克萊蒙奧弗涅大學的研究人員對8到12歲的男孩、經(jīng)過訓練的成年運動員和未經(jīng)訓練的成年人進行了分組研究，研究他們能量消耗和運動后恢復的情況。他們讓三組人進行一系列高強度的體育活動，結果發(fā)現(xiàn)孩子們表現(xiàn)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.”

該研究的作者、運動生理學家塞巴斯蒂安.拉泰爾在一份新聞稿中寫道:“我們發(fā)現(xiàn)，孩子們更多地使用了有氧代謝，因此在高強度的體育活動中，他們就沒那么疲勞了。他們也恢復得很快—甚至比訓練有素的成年耐力運動員還要快……這也許解釋了為什么成年人累了后，孩子們似乎還有精力可以一直玩很久。”

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

這些發(fā)現(xiàn)可以幫助那些想要培養(yǎng)孩子運動能力的父母。

“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.”

拉泰爾寫道:“我們的研究顯示，兒童的肌肉耐力通常很好，所以最好關注其他健身領域，比如他們的運動技巧、沖刺速度或肌肉力量。這可能有助于優(yōu)化孩子的體能訓練，使他們表現(xiàn)得更好，更享受運動。”
