Is training ever wasted, or worse still....detrimental

Agree at the elite level abecodates of hematocrit so high to cause coaguable blood, but I’d guess most of the studies that show prevelance of AF in endurance athletes are unlikely to have recruited elites and instead class endurance athletes as typical club marathon/triathletes? Given the low inclusion standards to be classed as an ‘athlete’ in most studies.
