This is a preliminary report of the experimental follow-up study for future long-term examination in order to understand the process of acclimatization through high altitude trekking experiences. This time, immunological and psychological changes through the two day trekking experience in the Northern Japan Alps were examined using various objective and subjective indexes. The immunological index included immunoglobulin A, G, M from serum, and salivary globulin A. The psychological index included RPE (Rate of Perceived Exertion), salivary cortisol, anxiety, motivation and feeling. In addition to these, body temperature, heart rate, SpO2 (percutaneous oxygen saturation), and subjective physical conditions were examined.  The various data examined in this study were corresponding among them in terms of experience levels, psychological conditions, physical conditions, and environmental conditions. We found the fact that concentration of salivary cortisol was associated with psychological change, and that salivary immunoglobulin A increased in concentration during the follwoing week after trekking compared to the next day after trekking. From our results we suggest that trekking may contribute to health promotion.  The results of this study showed various suggestions and possibilities for future study. The indexes for examination, trekking routes including altitude changes, period of trekking, experience levels of subjects, and psychological impacts of subjects should be carefully considered for future study.
