I have worked in Cardiac Rehab for over 20 years now as an Exercise Physiologist (Master's level from the U of Iowa and Ball State), and run for almost all of the last 35. I just returned from the national American College of Sports Medicine conference in lovely downtown Denver, and listed to people review research that shows that an hour OR MORE of daily aerobic exercise shows greater decreases in morbidity and mortality. 30 minute/day is a start, an hour a day gives more, and 90 minutes daily shows more yet, though the numbers level off some.
I personally don't believe Cooper's interpretations. How much do I do? About 25 to 35 miles per week, plus some cycling, since my legs don't seem to handle much (just turned 60, YEAH!). With my family history of heart problems, I do take a statin to lower my slowly increasing cholesterol, I just don't want to face the surgeon's scapel! Poor Rick, who knows, maybe it was not coronary disease, maybe his blood potassium levels were low due to
whatever. I wish we could ask him if he'd had any signs of it. There's more to sudden death than just coronary disease, unfortunately.
Personally, I ran 11 miles yesterday in 92 minutes in Des Moines, and 4 slow miles today, along with a 50 minute bike ride. No symptoms, and a local cardiologist told me that as long as I don't have any, I should not worry about a stress test, but if certainly have one if I have ANY suspect signs. Comments?
