The purpose of this study is to present the results from the survey of physiological and psychological reactions to health care on high altitude trekking. Subjects were eleven middle-aged female mountain trekkers of a mountaineering club. They were classified into two groups; one is seven subjects who performed all the trips (the completed group, group C) and the other is four subjects who descended a mountain because of their poor physical conditions (the descended group, group D). And then about these two groups physiological and psychological reactions in the high altitude trekking were discussed. As a result, it was shown that the measurements of pulse rate and SpO2 as the physiological index were effective in evaluating physical conditions when trekking. In addition, although RPC (Rating of Physical Condition) designed for making a psychological index is a simple and easy method, it was found to be an effective way to predict the extent of their mental fatigue. It is suggested from these results that the observation of physiological and psychological reactions is effective for health care on high altitude trekking and for prevention against sickness including AMS (acute mountain sickness).
