This definitely has me rethinking my retirement years training.
What about the studies that indicating going long and the associated heart inflammation can lead to damage or heart attacks? Seems that is more apt to happen in less fit marathons as I recall. Here is one such article:
https://breakingmuscle.com/learn/endurance-training-is-bad-for-your-heartKind of think Ed is dispelling this, or is quite the exception?
What about the studies showing that people who have high levels of physical activity have lower levels of 6 different markers related to cardiovascular disease than sedentary people?
For example:
https://www.ncbi.nlm.nih.gov/pubmed/15530595There is also this part in the NYT article:
A VO2 max reading of 54 appears to be unsurpassed for people tested in their 80s, said Scott Trappe, the director of the human-performance laboratory at Ball State University in Muncie, Ind., who has studied Swedish cross-country skiers who continued to perform at high levels into their 80s and early 90s, including the 1948 Olympic champion Martin Lundstrom.
“There’s nothing higher than that in the literature,†Trappe said of Whitlock. “It’s phenomenal physiology.â€
... a healthy young adult has about 160 motor units in the shin muscle, called the tibialis anterior, which helps lift the toes. In an octogenarian, that number could have declined to about 60 motor units, Hepple said, but Whitlock retained “closer to 100.â€
This preservation might largely be explained, he said, by a chronically elevated level of circulating chemicals, called neurotrophins, which protect and nurture neurons, helping them survive.
It might have something to do with the fact that ED HAS BEEN RUNNING 2 TO 3 HOURS PER DAY AND A LOT OF RACES FOR MANY YEARS (with no weight training so far).
