Abstract :The purpose of this study was to investigate regional differences in seasonal changes in physical activity levels among female university students in Japan's Okinawa and Ibaraki Prefectures. Participants were 58 female university students in Okinawa and Ibaraki Prefectures. The physical activity levels (total energy expenditure and durations of activities at different intensity levels) were measured using a uniaxial accelerometer on seven consecutive days including a weekend in both summer and winter seasons. Climatic conditions during the survey periods were also recorded. To evaluate seasonal changes in the physical activity levels, repeated measures ANOVA were performed using season (summer or winter) and region (Okinawa or Ibaragi) as independent variables and the physical activity levels as dependent variables. Repeated measures ANOVA indicated the main of season and region and interaction between them on the total energy expenditure. The total energy expenditure decreased from summer to winter in Okinawa but increased over the same period in Ibaragi. The total energy expenditure in winter was significantly lower in Okinawa than in Ibaragi. As for the duration of light activities, season showed a main effect, and interaction between region and season was observed. The duration of light activities was shorter in winter than in summer in Okinawa. Regarding vigorous activities, a main effect was noted in region, and the duration of vigorous activities was shorter in Okinawa than in Ibaragi. In conclusion, seasonal changes in the physical activity levels differed between female university students in Okinawa and Ibaragi, and the weather, i.e., rain, is considered to have affected the physical activity levels.
