Guest guest Posted April 24, 2007 Report Share Posted April 24, 2007 Hi Don: Yes. But what, imo, we learned from Jim Fixx, is that even if you train for years for running marathons, it isn't going to do much to prevent your arteries from becoming clogged if other factors are causing them to clog up. As I understand it his often repeated exhortation was that running marathons would make a person immune to heart disease. (Did he base this opinion on any serious evidence?). As we know, he couldn't have been more wrong. It reminds me of a close relative who all his life has exercised a lot, competitively. He is now reporting chest pains with exercise. The WUSTL data very clearly demonstrate the kinds of behaviour that **dramatically** improve cardiovascular risk factors, and according to carotid IMT measurements, apparently also the amount of arterial occlusion. Hopefully, the risk will turn out to be well correlated with the risk factor data. Although as far as I know that has yet to be categorically proven.
