BACKGROUND AND AIMS: Comparative data on locomotive and non-locomotive physical activity (PA) by age and gender are lacking for Japanese adults. The purpose of this study was to investigate objectively the levels of PA in each intensity in adults and older people by both genders living in Japan with triaxial accelerometry with discrimination between locomotive and non-locomotive PA. METHODS: In 571 women and 315 men aged 18-92 years from the Kanto region, PA was assessed for 6 consecutive days with a triaxial accelerometer (Active style Pro: HJA-350IT), and minutes of light and moderate-to-vigorous physical activity (MVPA) classified by metabolic equivalents were evaluated. RESULTS: Japanese elderly women over 70 years, spent less time in not only locomotive PA (light and MVPA), but also in non-locomotive MVPA. For non-locomotive light activity, however, there was no significant difference between women over 70 years and younger women. In contrast, for men, non-locomotive light activity and MVPA remained constant with age, while elderly men over 70 years spent less time in locomotive activities (light and MVPA). Women spent more time in non-locomotive activity than men, except for MVPA in elderly individuals, and time in non-locomotive MVPA occupied more than half of the total MVPA in all age groups for women. CONCLUSIONS: These findings suggest that the intensity and the type of PA for Japanese were obviously affected by age, while locomotive PA for men and non-locomotive light PA for Japanese women were obviously unaffected by age. The finding also indicates gender differences. Thus, evaluation of both locomotive and non-locomotive activity is important in the overall assessment of PA.
