“A routine of daily physical activity can be highly effective for prevention and treatment of many diseases, including coronary heart disease, hypertension, heart failure and obesity,” James O’Keefe, of the Mid-America Heart Institute of Saint Luke’s Hospital of Kansas City and co-author of the study, said in a prepared statement. But after reviewing the literature on extreme-endurance event participants, he and his colleagues found evidence that over time this type of training might be changing people’s hearts—and not for the better.
Indeed, a long-term study of 52,000 runners found that those who ran one to 20 miles a week spaced out over two to five days and at an 8.5- to 10-minute mile lived longest.
