If the initial work rate and RPE are set in a feedforward or anticipatory manner as is suggested (B and C on fig 2),
then the starting power output should be similar whenever exercise is performed at a given RPE, irrespective of experimental
interventions, such as increased ambient temperatures, hypoxia and
dietary interventions.
I realize that this is anecdotal, but I was able to ride my own cholesterol numbers down from 203 to 166 by means of
dietary intervention on my journey from omnivore to vegan; which was originally unintended, yet logical destination; by first eliminating beef, pork and lamb;
then to chicken skin removal, eliminating chicken altogether, fish off the menu until the only animal products left in my diet were a hard boiled egg, sliced, or 4 oz of poached shrimp, and sometimes both.
