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 great 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 on this podcast derived from the report. It’s an fascinating replace. Prior 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 rising with extra train, up to some extent. After that, mortality danger will increase once more. This isn’t born out in meta-analyses of the vast majority of research, nevertheless. 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 danger of creating sure cardiac abnormalities like Afib or scarring of the center. This appears to be extra seemingly for these doing a whole lot of excessive depth coaching.
So if you happen to’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 within the report like presumably present process cardiac screening to reduce the danger of cardiac abnormalities. As a result of I had a heart-valve substitute prior to now I’m underneath the continuing care of a heart specialist, and am glad to get periodically screened.
