Genes May Dictate How Exercise Benefits The Elderly

According to HealthDay News, researchers have identified a genetic trait that may help to explain why some older people get fewer benefits from physical activity than others.

It's a variant form of the gene that controls a molecule called angiotensin-converting enzyme (ACE), which is involved in blood pressure regulation.

A British study had previously found that the variant gene affected the physical response of Army recruits who carried it, said Stephen B. Kritchevsky, professor of gerontology at Wake Forest University School of Medicine.

Those people, ages 70 to 79 when the study started in 1997, have made periodic reports of their physical activity -- not only exercise but also everyday activities such as walking and stair climbing. They also have reported any mobility problems they might have.

"One of our most important findings was that everybody did better with exercise," Kritchevsky said. "But people with this genotype did not get the best response."
