I’ve talked prior to now (right here and right here) in regards to the idea of whether or not there’s a level past which train turns into an excessive amount of of a very good factor. Since I’m at all times tempted to push the envelope on this, I made a decision to ask Google Gemini deep analysis to research it for me: Endurance Train Quantity, Depth and Human Longevity. It got here up with this report, which is summarized in this podcast derived from the report. It’s an fascinating replace. Previously some research have appeared to point out a “U-shaped curve” of longevity vs train quantity: Train reduces all-cause mortality, with the profit growing with extra train, up to some extent. After that, mortality threat will increase once more. This isn’t born out in meta-analyses of the vast majority of research, nonetheless. As an alternative, all-cause mortality continues to go down irrespective of how a lot you train. However past a sure level, we’re at larger threat of creating sure cardiac abnormalities like Afib or scarring of the center. This appears to be extra seemingly for these doing quite a lot of excessive depth coaching.
So should you’re like me and luxuriate in a lot of endurance coaching, it’s a good suggestion to observe a system like polarized coaching the place most of your coaching is at simple depth, with a minority of exercises at larger depth. Different suggestions are additionally given in the report like probably present process cardiac screening to attenuate the chance of cardiac abnormalities. As a result of I had a heart-valve alternative prior to now I’m beneath the continued care of a heart specialist, and am glad to get periodically screened.
