The objective of this study was to examine and compare the levels and pattern of PA using an accelerometer in YO and OO groups. Methods: The subjects were assigned to YO group (23 men, 71±3 years; 45 women, 70±3 years) and OO group (29 men, 80±4 years; 36 women, 79±3 years), and the level of PA was measured using an accelerometer for two consecutive weeks. Results: The total number of daily steps was significantly higher in the YO group(men, 7,252±4,790 steps/day; women, 7,828±3,568 steps/day) than in the OO group (4,631±3,761steps/day; 5,827±2,546 steps/day) by both genders. The time spent in low-intensity PA was significantly lower in the OO group (men, 41.2±29.1 min/day; women, 51.4±17.6 min/day) than in the YO group (55.8±25.1 min/day; 61.1±22.6 min/day). The percent of low-intensity PA was significantly higher in the OO group than in the YO group. The time spent in moderate-to-high PA was significantly lower in the OO group (men, 9.2±13.9 min/day; women, 12.4±11.7 min/day) than in the YO group (19.1±22.1 min/day; 22.1±17.7 min/day). The percent of moderate to-high PA was significantly lower in the OO group than in the YO group. Conclusions: These results suggest that OO, compared with YO, has a significantly lower number of steps and this group spends more time in low-intensity PA than in moderate-to-high PA., application/pdf}, pages = {59--67}, title = {前期高齢者と後期高齢者の加速度計により評価した身体活動の比較}, year = {}, yomi = {ひがしおんな, あきよ and ながやま, ひろし and はまおか, たかふみ and まつもと, たかひで and よしだ, ごういちろう and よしたけ, ゆたか} }
