I’ve talked prior to now (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 I’m all the time tempted to push the envelope on this, I made a decision to ask Google Gemini deep analysis to research 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. 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 a degree. After that, mortality danger will increase once more. This isn’t born out in meta-analyses of nearly all of research, nonetheless. 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 center. This appears to be extra possible for these doing loads of excessive depth coaching.

So for those who’re like me and revel in a lot of endurance coaching, it’s a good suggestion to observe 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 probably present process cardiac screening to attenuate the chance of cardiac abnormalities. As a result of I had a heart-valve substitute prior to now I’m beneath the continued care of a heart specialist, and am glad to get periodically screened.
