that was a bad choice on my part, done quickly. yes, there is increased adaptation from training in the heat.
i do believe in specificity of training, but i was speaking more specifically about measurement of power and computation of TSS. hrTSS and other estimates for MTB, IME, overestimate training stress due to fluctuations in terrain and coasting where HR stays elevated relative to effort. since we're generally talking about goals that include putting more power into the pedals,
my opinion is that actual TSS (lower than hrTSS) remains the better measure of training load in the context of a PMC.
it all matters, just not very much.
