The purpose of this study was to examine the physiological effects of trekking and appreciation of landscape in Oze National Park. The subjects were 12 healthy men at old and middle age (53±5 yr). The measured physiological parameters were the R-R intervals of the electrocardiogram to analyze heart rate variability. The energy expenditure by Oze trekking was 905 kcal, and the volume of physical exercise calculated from METS that was 30.3 “exercise”. The “Ushikubi” point, the powers of the high frequency component tended to be higher and low frequency to high frequency ratio tended to be lower. The physiological responses suggested that sympathetic nervous activities were suppressed and parasympathetic nervous activities were enhanced in Oze area, and Ushikubi was particularly responsible for reducing the stress. In conclusion, the present study has proved life-style related diseases, the relaxing and stress-relieving effects of Oze by means of a physiological investigation.
