Research backs benefits of making exercise a priority

As the ball drops on the new year, exercise often tops the list of people’s resolutions. According to Zhen Yan, whose research highlights the benefits of exercise in improving health and preventing disease, science supports that choice for more than just getting in shape.

“Exercise is better than medicine,” says Yan, a professor and director of the Center for Exercise Medicine Research at the Fralin Biomedical Research Institute at VTC. “We need to start thinking beyond extending our lifespan and focus on extending our health span.” He is referring to that period of life free from chronic illness, pain and disease.

Yan’s research provides scientific support for the role of exercise and its effect on mitochondria, which are critical to maintaining health. Yan has found connections between malfunctioning mitochondria and cardiovascular disease, metabolic disease, cancer and cognitive decline. Among his research findings:

“Our body undergoes adaptations in response to exercise, not only to improve physical performance, but also to induce many other health benefits,” Yan says. “Physical activity and regular exercise are the best measures we have to promote good health and prevent disease.”
