The purpose of this study was to examine the relationship between age, functional abilities and physical activity of older women in Hong Kong. Participants (N = 189, aged 65 - 88 years) undertook a battery of Functional Fitness Test, including 30-s chair stand, arm curl, 2-minute step test, chair sit and reach, back scratch, 8-ft up and go and body mass index (BMI) (Jones & Rikli, 1999). Their physical activity level was assessed using the Physical Activity Scale for the Elderly (PASE) developed by Janney et al. (1993). Individuals were categorized into groups based on their age (60-69 years old, n = 55; 70-79 years old, n = 110 and aged 80 years or above, n = 24) and activity level (sedentary, n = 73 and active, n = 116). 2 X 3 ANOVAs were utilized with two activity levels (sedentary or active) and three age groups (60-69 years old, or 70-79 years old or aged 80 years or above). Results showed that no interaction effect of age by activity level was found in functional fitness performance and PASE score. Activity level accounted for differences in all functional fitness test items as those who were active performed better than those who were sedentary. Cross-sectional result showed that younger group scored better on lower body strength, aerobic endurance, upper body flexibility and agility. Active participants scored higher in the PASE than sedentary participants. Higher PASE score was recorded in the younger group. Performances in 30-s chair stand, 2-minute step test, back scratch and 8-ft up and go declined with age. Higher PASE related to better performance in 30-s chair stand, arm curl, 2-minute step test and 8-ft up and go. This investigation provided evidence that physical activity participation has positive influence on functional fitness of older women.
