Any research (as opposed to anecdote) on the adaptations for acute vs. chronic volume of zone 2 work?
For the purposes of discussion: acute volume = length of one LSD training session; chronic volume = total amount training LSD for the season.
Some months, I don’t have the time for even one long weekend ride – the longest may cap out at 2.5-3 hours. But, each week will be 14-16 hours of riding, with the vast majority of it in Seiler’s HR zone 1.
Question: over the course of year, will overall training volume spent below AeT “even out” although there may not be a lot of 4-5 hour rides. Is, say, 700 hours still 700 hours, and the adaptations will happen? Or, would that be less effective than someone else getting the same 700 hours, but with 40+ long, 4 hour rides during that year?
Lets assume the number of interval days are equal between the two riders, as are the number of weight sessions, ability to recover, etc…
