I’ve talked prior to now (right here and right here) concerning 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 analyze 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. Up to now some research have appeared to indicate 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 a substitute, all-cause mortality continues to go down irrespective of how a lot you train. However past a sure level, we’re at greater threat of growing sure cardiac abnormalities like Afib or scarring of the center. This appears to be extra probably for these doing quite a lot of excessive depth coaching.
So for those who’re like me and luxuriate in a lot of endurance coaching, it’s a good suggestion to comply with a system like polarized coaching the place most of your coaching is at simple depth, with a minority of exercises at greater depth. Different suggestions are additionally given in the report like probably present process cardiac screening to attenuate the danger of cardiac abnormalities. As a result of I had a heart-valve alternative prior to now I’m beneath the continuing care of a heart specialist, and am glad to get periodically screened.
