offers one possibility: Hormonal changes reduce the ability for women to form tiny blood vessels in their muscles, increasing the risk of cardiovascular conditions and especiallyFortunately, researchers suggest, this doesn’t have to be inevitable, because short-term exercise can help—after menopause, but especially before it.Researchers looked at two groups of women: 12 were between 59 to 70 years old and five were between 21 to 28 years old.
The younger group who started exercising before they hit menopause showed an increase in the number of capillaries—or small blood vessels—in skeletal muscle tissue at the end of the study period, while the older group did not. Capillaries, which helpand fat absorb into the muscles for more efficient usage as fuel, also have an effect on insulin resistance. That’s why having less of an ability to grow new ones could raise cardiovascular concerns.
That doesn’t mean post-menopause exercise is a wash, though. In the study, even though they didn’t show significant capillary growth, the older group did improve their exercise capacity by 15 percent. That, in itself, is a cardiovascular boost, according to study coauthor
