Physical activity and sedentary behavior patterns were objectively measured by an ActiGraph GT3X accelerometer in centenarians (n = 18; 83% women; 100.8 ± 0.8 [100–103] years) and nonagenarians (n = 11; 91% women; 93.3 ± 2.5 [90–98] years). Centenarians showed less counts per minute (17.6 ± 7.1 vs. 46.1 ± 23.7, p = .003, d = 1.851) and steps per day (455 ± 237 vs. 1,249 ± 776, p = .007, d = 1.587) than nonagenarians. The daily number of sedentary breaks was also lower in the former (5.0 ± 1.5 vs. 6.7 ± 2.0, p = .019, d = 0.971). When observing time distribution, the most active day period in both groups was the morning, with a peak between 10:00 and 11:59. This data suggest that the decline in physical activity levels continues to worsen until the end of the human lifespan.2019http://zaguan.unizar.es/record/13126810.1123/japa.2018-0122http://zaguan.unizar.es/record/131268oai:zaguan.unizar.es:131268info:eu-repo/grantAgreement/ES/MEC/FPU16-05879JOURNAL OF AGING AND PHYSICAL ACTIVITY 27, 6 (2019), 899-905All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
