There have been various versions of recommendations for physical activity in older adults, all aiming to improve or maintain health. This is not surprising as the commonest version is to accumulate at least 30 minutes of aerobic moderate-intensity physical activity at least 5 days per week (i.e., around 600 Kcal). To examine the relationship between physical activity and other functional outcomes, naming fear of falls and functional mobility, this cross-sectional study recruited 142 older adults with a mean age of 76.0±7.3 years living in the community. The physical activity measured by the Taiwan International Physical Activity Questionnaire-Short Form, which included walking and different degrees of aerobic activities, had an average of 2702 Kcal (95% CI 2278 - 3126). There was significantly less fear of falls, measured by the short version of Falls Efficacy Scale International, in those who exercised more than 600 Kcal per week (T140=3.879, P<0.001). The linear regression model after controlling for age and gender revealed only one contributing factor remained statistically significant: physical activity (β=-0.237, P=0.011). Besides, the fast gait speed was significantly higher in those who exercised more than 600 Kcal per week (T139=-2.200, P=0.029). The linear regression model revealed three significant contributing factors: age (β=-0.538, P<0.011), gender (β=0.254, P=0.001), and physical activity (β=0.165, P =0.029). This study provides novel insights into the relationship between aerobic physical activity and functional outcomes others than health outcomes.
