Record response to call for new astronauts
TUSCALOOSA, Ala., Feb. 5 (UPI) -- Our genetic makeup determines how much endurance we can build from exercising, scientists at the University of Alabama said.
The scientists found about 20 percent of all people don't build as much endurance as others from exercise because of their genetic makeup.
That doesn't mean, however, that exercise isn't beneficial, said the scientists, who teamed with researchers at the Pennington Biomedical Center in Baton Rouge, La.
If you are in that 20 percent, exercise won't build much endurance but it can improve heart rate, cholesterol levels, blood pressure and insulin metabolism, researcher Tuomo Rankinen said.
"That's an important public health message," Rankinen told USA today in story published Friday.
The study's findings could help personalize exercise regimes to help people get the most from their workouts, the study's co-author Molly Bray said.
"Having genetic information about a person can at least give us some informed guidance," she said.
