Physical fitness is evolving as a significant factor related to cognitive health in older age. A study published in May 2015 found that higher levels of physical fitness in middle-aged adults were associated with larger brain volumes five years later.

This study shows that for people with heart disease, fitness might be particularly important for prevention of brain aging, Spartano said.

“We found that poor physical fitness in midlife was linked to more rapid brain aging two decades later,” she said. “This message may be especially important for people with heart disease or at risk for heart disease, in which we found an even stronger relationship between fitness and brain aging.”

The researchers also found that people with higher blood pressure and heart rate during exercise were more likely to have smaller brain sizes 20 years later. People with poor physical fitness usually have higher blood pressure and heart rate responses to low levels of exercise compared to people who exercise more, Spartano said

“From other studies, we know that exercise training programs that improve fitness may increase blood flow and oxygen to the brain over the short term,” Spartano said. “Over the course of a lifetime, improved blood flow may have an impact on brain aging and prevent cognitive decline in older age.”

The study suggests promotion of physical fitness during middle age is an important step toward ensuring healthy brain aging.

“The broad message,” Spartano said, “is that health and lifestyle choices that you make throughout your life may have consequences many years later.”
