Study says swimmers have lower death rate than runners

A new study by researchers at the University of South Carolina says that swimming cuts men's risk of dying by about 50 percent compared to runners, walkers and sedentary peers.

The study was led by Dr. Steven Blair.

It evaluated comprehensive physical exams and behavioral surveys from thousands of people who were enrolled in the Aerobics Center Longitudinal Study over the last 32 years.

"Swimmers had the lowest death rate," said Blair. Regular swimmers had a higher cardiorespiratory fitness than walkers.
