While physical activity (PA) may counteract age-related functional decline and loss of independence at old age, to what extent physical function is influenced by past or present PA behaviors is currently unclear. Therefore, the aim of the study was to examine relationships between both past and present PA behaviors and components of physical function in older women. A physical function score based on the 6-minute walk test, squat jump, and single-leg-stance balance was aggregated in 60 older women (65-70 years). Present PA behavior was assessed by accelerometry (Actigraph) and past leisure-time PA was self-reported, where times in sports-related activities and in walking were analyzed separately. Analysis of differences in physical function across tertiles of PA behaviors was adjusted by DXA-derived fat mass. Physical activity level at present age and engagements in sports-related activities before retirement age, excluding walking, were both associated (P < 0.05) to physical function. Time spent in PA of at least moderate intensity was associated with physical function (P < 0.05), whereas no corresponding relationships to either sedentary time or time in light intensity PA were observed. In conclusion, PA behaviors at present age and engagement in sports-related activities performed during adulthood are both related to physical function in older women. Being physically active at old age infers beneficial effects on physical function, even in individuals with a past or present sedentary lifestyle, which supports public health efforts aiming at increasing daily time in PA of at least moderate intensity to preserve physical function in older women.
