| Outline of Final Research Achievements |
Participants (n = 297) wore an accelerometer and completed a survey and physical functions performance test. Sedentary behavior(SB) accounted for 8.7hrs a day (58 % of wear time), with 7.7 breaks per sedentary hour, and 4.4 prolonged SB bouts per day (42% of total SB). Men, those aged over 75 years, and those with BMI over 25 had significantly more ST than the counterparts. The highest proportion of ST in 6 different domains were TV viewing (46.9%).TV viewing was significantly associated with higher proportion of prolonged bouts and less breaks. Replacing 10minutes-SB to moderate-to vigorous physical activity (MVPA) was significantly and favorably associated with most of physical function measures and health-related QOL(SF-8). For improving the health and functional well-being of Japanese older adults, there may be benefit from replacing at least 10-minutes SB to MVPA with more frequent breaks, especially during TV viewing, particularly for those who are older and overweight/obese.
