We investigated a case of the changes in the indices of pulmonary function in one individual with a current medical history of bronchial asthma（ CHA） during the hiking of Mt. Kono in winter. In this study, forced expiratory volume in one second（ FEV1.0） with respect to rest condition （FEV1.0%fall）, predicted FEV1.0 （%FEV1.0） and an assessment of dyspnea sensation （ADS） were measured at the three points （P1: alti. 52 m, P2: alti. 341 m, P3: alti. 96 m）. From the results of changes in FEV1.0%fall, %FEV1.0 and ADS, the pulmonary function indicated a remarkably decrease during the ascending. It was to reach a level of exercise induced asthma attack under the conditions of this investigation.
