I am an avid recreational runner. I am just about to come up on my 2 year anniversary of being a pretty regular runner, see Operation: Marathon. So it was pretty disturbing to see these two abstracts getting press form the 2010 American College of Cardiology:
- Researchers have shown that long-term marathon runners, those who have completed at least 25 marathons over the past 25 years, have increased coronary calcium and calcified plaque volume.
- A second group did a study which suggested that marathon runners had increased aortic stiffness compared with individuals who exercised recreationally
- lower heart rate
- lower body weight
- lower BMI
- Higher HDL-cholesterol levels
