Dear Biomch-l people,

I am a Sport Physiologist and currently working with a road cyclist. We have a problem during his high altitude. His maximum HR and blood lactate attained on sea level training are 195 bpm and 19 mM, respectively. But whenever he ascent to the altitude higher than 1800m, his maximum HR would drop to 180 bpm and his maximum lactate would only be around 12 - 14 mM, even though he had been stayed at that altitude for about one month. This phenomenon have been happened 3 times. May I ask anyone to suggest the cause and solution of this problem.

A summary of the reply will be posted.
