Apparently the authors believe that the energy turnover per muscle mass is an operative factor, not simply the quantity of O2 2 consumed.
That's a very interesting point. I would then suppose that the way your are reading this, the more watts one can put out at VT1, the stronger the stimulus becomes, so it's a thing that builds on itself. However I think that while the lower energy turnover of an untrained person would then supply less stimulus, they would perceive an intensity similar to that perceived by a trained athlete. I did read that the same polarized workouts are prescribed for all athletes regardless of training status.
