Study says Some Folks Have a Lazy Gene

Could genes be to blame for a lack of motivation to hit the gym? A recent study conducted at the University of Missouri suggests this could be the case.

By studying a population of rats over ten generations, researchers came to the conclusion that there is such a thing as a genetic predisposition to laziness, at least among rodents. The study was conducted by Franck W. Booth and Michael D. Roberts of the University of Missouri’s College of Veterinary Medicine and the results were published in the latest issue of the American Journal of Physiology.

Around 50 rats were placed in cages with running wheels. Over a period of six days, researchers recorded the amount of time each rat spent willingly running on its wheel. The rats were then separated into two breeding groups, so that the 26 most active rats bred only amongst themselves, and the 26 least active bred only with each other. The process was then repeated over ten generations.

At the end of the experiment, the researchers observed that the rodents from the “super runners” line willingly ran 10 times longer per day on average than those from the “couch potato” line.
