Objectives Physical activity–an important determinant of health and function in old age–may vary according to the life-space area reached. Our aim was to study how moving through greater life-space areas is associated with greater physical activity of community-dwelling older people. The association between objectively measured physical activity and life-space area reached on different days by the same individual was studied using one-week longitudinal data, to provide insight in causal relationships. Methods One-week surveillance of objectively assessed physical activity of community-dwelling 70–90-year-old people in central Finland from the “Life-space mobility in old age” cohort substudy (N = 174). In spring 2012, participants wore an accelerometer for 7 days and completed a daily diary including the largest life-space area reached (inside home, outside home, neighborhood, town, and beyond town). The daily step count, and the time in moderate (incl. walking) and low activity and sedentary behavior were assessed. Differences in physical activity between days on which different life-space areas were reached were tested using Generalized Estimation Equation models (within-group comparison). Results Participants’ mean age was 80.4±4.2 years and 63.5% were female. Participants had higher average step counts (p < .001) and greater moderate and low activity time (p < .001) on days when greater life-space areas were reached, from the home to the town area. Only low activity time continued to increase when moving beyond the town. Conclusion Community-dwelling older people were more physically active on days when they moved through greater life-space areas. While it is unknown whether physical activity was a motivator to leave the home, intervention studies are needed to determine whether facilitation of daily outdoor mobility, regardless of the purpose, may be beneficial in terms of promoting physical activity. ...

Timed up-and-go performance is associated with objectively measured life space in patients 3 months after ischemic stroke : a cross-sectional observational study Rössler, Roland; Rommers, Nikki; Kim, Eun-Kyeong; Iendra, Laura; Sofios, Alexander; Giannouli, Eleftheria; Portegijs, Erja; Rantanen, Taina; Infanger, Denis; Bridenbaugh, Stephanie; Engelter, Stefan T.; Schmidt-Trucksäss, Arno; Weibel, Robert; Peters, Nils; Hinrichs, Timo (Springer Science and Business Media LLC, 2022)Background Stroke is a common cause of mobility limitation, including a reduction in life space. Life space is defined as the spatial extent in which a person moves within a specified period of time. We aimed to analyze ...
Objectively measured physical activity and physical performance in old age Jantunen, Hanna; Wasenius, Niko; Salonen, Minna K.; Perälä, Mia-Maria; Osmond, Clive; Kautiainen, Hannu; Simonen, Mika; Pohjolainen, Pertti; Kajantie, Eero; Rantanen, Taina; von Bonsdorff, Mikaela; Eriksson, Johan G. (Oxford University Press; British Geriatrics Society, 2017)Background physical performance is a key factor that determines how older people cope with daily tasks and maintain independency. There is strong evidence suggesting that physical activity (PA) is important in maintaining ...

Longitudinal associations among cardiorespiratory fitness and objectively measured moderate-to-vigorous physical activity of Finnish schoolchildren Jaakkola, Timo; Huhtiniemi, Mikko; Salin, Kasper (Oxford University Press (OUP), 2022)Children and adolescents' engagement in physical activity has decreased in most Western countries across the previous three decades. Therefore, increasing number of researchers are investigating antecedents of physical ...
