Quadruple-Digit Post Count
@Bret S.Steve I just read this article posted by @krg , If you haven't read it yet it confirms my gut feeling that too much extreme endurance training must exact some kind of toll on the CVS. I've always been suspicious of that kind of training (for me) and have never been drawn to it.
MA training, which I've done my whole adult life is more HIIT and interval work which I'm very comfortable with. Again I'm speaking purely from my own 'gut feeling' on this. Also A+A is a big part of my CV health strategy too..
Definitely food for thought, and does suggest that intensive endurance training is not necessarily good for CV health or for longevity (while many endurance athletes probably don't train and compete for health reasons, I'm sure many or most assume it has a health benefit).
I've never been drawn to intensive endurance training either, but I have run myself into the ground on a regular basis for many years on the basketball court. I still play, but have lots of orthopedic wear and tear that limits how often or hard I can go. Younger players often remark on my stamina, but the truth is that I can no longer really run fast enough or jump high enough to get tired.
