If you are riding z2 but your HR drifts up die to heat, do you keep aiming at z2 hr or at z2 wattage? In other words, is z2 hr at cold temp the same z2 hr at a hot temperature. I would guess it doesn't represent the same lactate level.
Dear Dr Seiler. Thank you for all this great content. I have learned a lot, but still struggle with one question: only you can shed light. I run in Singapore, hot and humid and variable (rain comes and gets fresh), so it's common to have workouts where pace is the same but HR very different, or vice versa. Question: if I'm training my lactate threshold, should I train at my LT pace or LT HR? Likewise for aerobic or VO2max training. In other words, when HR is affected by external factors, should I still trust HR zones to produce the physiological response I'm targeting? I could not find one single clear and scientific answer to this :( In this video you say that HR is affected by heat, but if we don't have fans should we keep on looking at HR? Or pace/power?
PS: I'm asking because the more I read about pyruvate and mitochondria and glycogen and lactate, the less I find about HR. Of course we need blood and oxygen to fuel our performance, but do we start accumulating lactate when the power output is too large (pace) or when HR reaches a certain threshold? What happens inside my body when HR is high because of the heat and not the power output? I get so confused 😅
how this only got 1,2k subs ....?
love your videos, always learning a lot of new stuff. thanks!
interesting as always. Keep it up Mr Seiler!
Great explanation!
Crazy about your new channel
