I’ve talked up 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 attention-grabbing replace. Up 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 a degree. After that, mortality danger will increase once more. This isn’t born out in meta-analyses of nearly all of research, nevertheless. As a substitute, all-cause mortality continues to go down regardless 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 guts. This appears to be extra possible for these doing numerous 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 straightforward depth, with a minority of exercises at larger depth. Different suggestions are additionally given in the report like presumably present process cardiac screening to attenuate the chance of cardiac abnormalities. As a result of I had a heart-valve substitute up to now I’m below the continued care of a heart specialist, and am glad to get periodically screened.
