Iâve talked previously (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 superb factor. Since Iâm 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. Previously some research have appeared to indicate a âU-shaped curveâ 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 the vast majority of research, nevertheless. As an alternative, 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 growing sure cardiac abnormalities like Afib or scarring of the guts. This appears to be extra seemingly for these doing a number of excessive depth coaching.
So for those whoâre like me and revel in plenty of endurance coaching, itâs a good suggestion to observe 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 probably present process cardiac screening to attenuate the chance of cardiac abnormalities. As a result of I had a heart-valve alternative previously Iâm below the continued care of a heart specialist, and am glad to get periodically screened.
