More and more people grow obese and the trend to children is more and more apparent.
Studies show 97 percent of American adults get less than 30 minutes of exercise a day, which is the minimum recommended amount based on federal guidelines.
However a professor says that certain genetic traits may predispose people to being more or less motivated to exercise and remain active.
A new study published in the American Journal of Physiology: Regulatory, integrative and Comparative Physiology on April 3, 2013, illustrated their experience that they created cages with running wheels and put rats in them. The tested how much rats willingly run on the wheels. Top 26 rats that were willing to run were reared together and top 26 rats that were laziest were bred with each other. In the eleventh generation of the bred rats, researchers found that the line of running rats chose to run 10 times than that of “lazy” rats.
They then examine physical differences and differences in level of gene and it turned out that there were minor differences in physical composition, but genetic differences in one part of brain may cause rats to have motivation to run.
This research indicate that genetics could play a role in exercise motivation, even in humans.
