Everything you need to know about do you take after your dad.
[ad_1]On a bright afternoon in Jiangsu, China, Xin Yin is playing personal trainer to some mice. One by one, he sets the rodents on a miniature treadmill that starts slow and gradually speeds up. These littermates are born athletes, able to run farther with less lactic acid buildup than average laboratory mice.
The secret to their speediness isn’t carried in their genes—the animals come from the same genetic stock as a group of control mice. And they haven’t received any special training. Instead, their fitness seems to stem from their father’s exercise habits before they were even conceived. It’s a finding suggesting that running might benefit not just the exerciser, but also his unborn children.
“I was very surprised when I first saw the data,” says Yin, a biochemist at Nanjing University.

Mice born to fathers who exercised before conception could run farther with less lactic acid buildup than average laboratory mice, even though they received no special training.
The athletic mice come from the same genetic stock as a group of control mice, so their speediness was not carried in their genes, which surprised biochemist Xin Yin when he first saw the data.
The study was led by Xin Yin, a biochemist at Nanjing University, working with the mice in Jiangsu, China.
It suggests that running might benefit not just the person exercising, but also his unborn children.
