The general consensus seems to be that cardio is catabolic to muscle growth, but boxers do more cardio arguably than any other sport, with the exception of marathon runners and swimmers, so how is it that they don't lose that precious muscle? Are they activating their muscle fibers differently, to make them recover better despite the many miles they jog, on average and other variable cardio activity they engage in?
Also, considering all the cardio boxers do, why don't they die as many sudden deaths as, say runners and soccer players? In fact I never hear about boxers suffering sudden training death, the only deaths I hear about in boxing are from things like subdural hemorrhage from getting punched in the head too hard, but this only happens rarely.
