Extreme Exercise Can Be Worse Than No Exercise

Health expert Dr. Mitchell Brooks visited 'Mornings With Ken & Bernie' today to discuss recent research that suggests extreme exercise could cause heart problems.  Brooks said studies specifically found that extreme exercises, such as marathons and triathlons could cause heart damage.

One study found that in 100 marathon runners considered healthy, 12 percent showed heart scaring, a rate that is three times higher than non-marathon runners.

Dr. Brooks said, "the recommendation is two and a half hours of exercise a week or one and a quarter hours per week if you exercise vigorously."

Brooks said even with heart problems there are many other medical problems that are worse and cannot be treated with surgery or medication.
