概要

In this study, we calculated physical activity scores, according to the time spent and energy expenditure in daily life. The subjects were 290 volunteers who were 53 students of the University, and 237 workers. Examinations were made twice at an interval of about 6 months in a test-retest examination. Physical activity scores were calculated from the life activity index of the "Japanese Nutritive Requirement". The amount of energy expenditure was calculated from the time spent, and base metabolism during activity of each subject. The physical activity scores obtained in the test and retest examinations showed a high correlation (r=0.86), confirming our recently developed questionnaire's ability to yield reproducible results. Our results show no sex difference in energy expenditure and Japanese Nutritive Requirement. Therefore, the method of calculation of energy expended per day (according to physical activity score) is highly objective and great deal of confidence can be placed in it.
