I’ve talked up 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 an excellent 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 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. 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 threat 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 irrespective of how a lot you train. However past a sure level, we’re at increased threat of growing sure cardiac abnormalities like Afib or scarring of the center. This appears to be extra probably for these doing a variety of excessive depth coaching.
So for those who’re like me and revel 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 increased depth. Different suggestions are additionally given in the report like presumably present process cardiac screening to reduce the chance of cardiac abnormalities. As a result of I had a heart-valve substitute up to now I’m below the continuing care of a heart specialist, and am glad to get periodically screened.
