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 an excellent 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. Prior to now 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 danger will increase once more. This isn’t born out in meta-analyses of nearly all 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 larger danger of creating sure cardiac abnormalities like Afib or scarring of the center. This appears to be extra possible for these doing lots of excessive depth coaching.
So in case you’re like me and luxuriate in numerous 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 larger depth. Different suggestions are additionally given in the report like presumably present process cardiac screening to reduce 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.
