Men who exercise may delay age-related high cholesterol

Men who get plenty of aerobic exercise may delay the onset of age-related high cholesterol, potentially lowering their risk for heart disease, a new study suggests.

Researchers followed thousands of men over several decades, periodically drawing blood to test their cholesterol and then making them run on treadmills to measure their cardiorespiratory fitness.

Men who could run longer and faster - signs that their bodies more easily deliver oxygen to muscles - also had lower cholesterol.
