一項追蹤研究43代老鼠的試驗表明,比起那些原本相對安靜的老鼠的后代,那些原本相對活躍的老鼠的后代跑輪子的所花時間要比它們長兩倍。
An experiment tracking mice for 43 generations finds that progeny1 of those that initially2 were more active are spending three times as much time on the training wheel as the progeny of the initially more sedentary mice. Christopher Intagliata reports
 
Always finding excuses to skip the gym? Congrats—you might be able to blame your genes3. Because the mere4 desire to exercise may be inherited, at least in mice. So says a study in the journal Proceedings5 of the Royal Society B.
 
The experiment started back in 1993 with 224 mice, divided into eight groups. In four of the groups, the researchers mated the males and females that logged the most distance on their exercise wheels. For the other four groups, they just randomly6 bred the mice.
 
Forty-three generations later, the mice descended7 from long distance runners are voluntarily running seven miles a day—three times as far as their lazy counterparts. And they cover those miles in different ways—some are marathoners, while others, especially females, run faster for fewer hours.
 
The running mice do have physical advantages, like better endurance and less body fat. But it's not just fitness. Previous studies suggest something's changing in the mice's brains too, turning them into exercise addicts8. And since mice and humans have similar genes, our itch9 to hit the track might also depend on how often mom and dad liked to throw on their running shoes.
