I have no source for this other than my husband mentioning an article he read. It states that high cardio in men (doesn’t apply to the woman in this story) suppresses the production of testosterone in middle age and older men. This can lead to heart/cardiovascular issues that cause the guy who is in incredible shape to drop from a sudden heart attack while running.
Just happened, yet again, to someone he knows. The guy was 49 years old and ran or biked daily. My husband called a friend who also knew the guy and said,” Stop running.”
Weightlifting is beneficial to men, but not long distance running. No studies on middle age women and long distance running AFAIK. I’m thinking I need to get back to weightlifting.
Running and crapping out stories seem to be far more than anecdotal. Go for the weights, though don’t go overboard.
