Abstract
During the period between June 1969 and May 1970 basal metabolic rate was experimentally conducted on 10 Japan Maritime Self-Defence Force members and 9 U.S. Marine Corps members both stationed at Sasebo. Results are as follows:
Under the West-Japan climate, it was confirmed that seasonal variation of BMR was noted on Caucasians as well as Japanese. The pattern of the variation showed a two-peaked curve which lowered in mid-summer and mid-winter in case of Americans against the variation of a one-peaked curve annually among Japanese. Lowered metabolism in Americans in the winter was thought due to reduction of work loads and less outdoor exposures. The fact that they live a more comfortable temperature that is about 10 degrees higher than temperatures in usual Japanese living conditions should be considered. As for RQ, that of Americans was always lower than Japanese throughout the year. These probably can be attributed to differences in daily dietary fats.
