I am somewhat interested in the relationship between the above. I'm told that all the body cares about is the actually amount of work done and hence this is how fitness is improve - demand more and the body adapts.
However, I am not quite sure I understand. Yesterday I rode for a couple of hours at 170W, the temp outside was 38 degrees C. Percieved exertion felt rather high. It seemed like my body, amongst working hard to turn the pedals was also taxed by the high heat.
Maintaining this wattage when it is cooler out - 20C - feels much easier.
And so my question: Is my body not burning more calories during the hot ride in light that it feels much harder? I'm trying to understand the dynamics of it. (needless to say, in the hot weather my heart rate is higher).
Note: prior to both rides I am sufficently rested.
