The purpose of the present investigation was to examine the amount, frequency and duration of daily physical activity in young to middle-aged Japanese women. A total of 70 healthy Japanese women, aged from 19 to 70 years, participated in the present investigation. All subjects wore an activity monitor (Lifecorder, Kenz, Japan) over a seven-day period, in order to determine the amount and frequency of light, moderate, and vigorous intensity physical activity (LPA, MPA, VPA) and the time duration of the physical activity (4sec to 1800sec). Furthermore, the sum of the MPA and the VPA was defined as the MVPA. The maximal oxygen uptake was measured by an incremental treadmill test. The subjects were categorized as ACTIVE or INACTIVE as well as FIT or UNFIT according to the amount of MVPA, as well as the value of maximal oxygen uptake. As a result, ACTIVE participants spent a significantly longer time in MPA which lasted longer than 8sec, in comparison to INACTIVE subjects (p<0.05). Of the total MVPA, the distribution of continuous MVPA (>180sec) was significantly larger for ACTIVE subjects in comparison to that of INACTIVE subjects (p<0.05). Furthermore, FIT subjects spent a significantly longer time in continuous MVPA (60 to 180sec) in comparison to UNFIT subjects (p<0.05). These results indicate that the active and/or physically fit individuals participated in more continuous intensive physical activity in comparison to inactive and/or lower fitness individuals.
