Too much training can affect acclimatization?

    This topic came to my mind recently, when I came across of case of sudden death of amateur mountaineer with good Marathon & IRONMAN results on one of the high camps (5400m).

    I also have read cases when elite sportsmen actually suffer when going to high mountains.
    It was very interesting to me what could be a reason, so here is the theory which is I am curous about.

    1. When the elite Ironman/triathlon sportsmen is starting the routine acclimatization his body react to the altitude elevation as Training adjusting the heart-rate, i.e. body does not respond the stress, lack of oxygen by starting to “acclimatize”, instead, the body switching on the day-to-day habit of responding to it as a tough training. Usually, such athletes feel great o first acclimatization days, in contrary averagely trained person, started to feel the stress and the body starting to produce hemoglobin, adjusting to the altitude.

    2. In the middle of acclimatization sportsmen’s body not able to compensate the lack of oxygen by heart output, which often leads to rapid deterioration – HACE , HAPE or other symptoms. (usually, this happens on one of the high camps). WHile the less trained person by that time fully adjusted and getting to his optimal performance.

    Do you think this might be true? I need to notice that this behaviour usually applies for Elite Athletes, who might have trained almost everyday and not very experienced in Mountaineering (not exposed to high altitude).

    You are correct in this assumption. The very fit athlete will not increase breathing as much as the less fit person so they tend to be more prone to acute mountain sickness. They also tend to go too fast before they are well acclimated and so the the climb too high too fast and are more likely to get HACE or HAPE. Steve and I just spoke a symposium on altitude for the Special Forces from several countries and this subject was discussed at length.

    Hi Scott, were you able to record the symposium in a manner you could share a link to? I would love to listen to that talk.

    Thank you
