While I still remain convinced that exercise has increased the likelihood I will be fit enough to enjoy old age, the overall body of evidence does demonstrate that a large amount to exercise increases some health risks.
At last week’s British Cardiovascular Society virtual meeting, Dr Gemma Parry-Williams from St George's University of London presented results of a prospective study of 214 healthy, middle-aged, male master endurance athletes including runners, cyclists, and swimmers, aged 40-65 years. They cycled, ran or swam, or did any combination of these for at least 6 hours per week (median 8.5 hours).
More than a quarter of athletes were found to have resting hypertension. 16% had a Coronary Artery Calcification (score >100 Agatston units, considered adverse risk in the general population); 5% exhibited significant coronary stenosis; a third (32%) of all plaques in the walls of the arteries were non-calcified (27% mixed and 5% soft); and 13% had additional plaque vulnerability markers.

Were these traits highly correlated? Would be useful to know as blood pressure is easily checked.

Elevated blood pressure was correlated with the other abnormalities. Checking BP is probably sensible

Moderation is best for the body. Any excess is detrimental.

And what did the good doctor find for the fraction of the cohort in the longitudinal study conatining people who were not endurance athletes?

I read an article today that there is a strong link between developing MND/ALS and excessive i.e. extreme levels of exercise...

My question would be the same as SNR's. How did the population of endurance athletes compare with age-matched controls? Is it a case of "endurance exercise has an adverse effect on cardiovascular risk" or "doing endurance exercise is no guarantee of freedom from cardiovascular risk"? The implications for behaviour would be very different.
Fenners, citations desperately needed.

I might be part of that study as I have been going to St George’s Cardiology since March 2020. It may be relevant that it is associated with some of the top sports cardiology professionals. They will get a lot of people like me who get referred to them that have certain cardiac symptoms.
I’ve read quite a lot of studies on exercise induced heart conditions since my HCM diagnosis. It seems likely that my heart wall thickening is exercise induced, however it is also a genetic issue that has made this happen. My cardiologist (Prof Sharma - he’s been on the tele today talking about Eriksen) advises that although my SCD (sudden cardiac death) risks have increased, particularly when exercising in the heat, overall my level of fitness is likely to produce a beneficial balancing of the risk. He’s advised me to keep running, but I am being sensible, avoiding intervals 5k races etc. I’m mostly running at about 120bpm whereas before it averaged about 135 (and over a minute/mile quicker).
Life is full of risks. I was very happy with the way the risk was communicated to me. I do have a higher risk of SDC when running, but probably less than if I was significantly overweight and unfit and just walking.
