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 physical performance in old age. However, most studies have been done using self-reported PA. Our aim was to explore the association between objectively measured PA and physical performance in old age. Methods we studied 695 participants (mean age 70.7 years, SD 2.7) from the Helsinki Birth Cohort Study. Physical performance was assessed with the Senior Fitness Test (SFT) and PA with a multisensory activity monitor SenseWear Pro 3 Armband. Results total volume of PA was significantly associated with the overall SFT score (β = 0.08; 95% confidence interval: 0.07–0.10, P < 0.001). There were no significant differences between men and women. Both light and moderate to vigorous level of PA were positively associated with the overall SFT score, while sedentary time was negatively associated with the overall SFT score. Conclusions volume of objectively measured PA among older people was positively associated with the physical performance measured with a validated fitness test battery. ...
