Hong Kong Sports Development Board (2000) reported that only an average of 44% of the adult (15 years and older) population participated in at least one physical activity in 2000. This was lower than the 54% in 1998 and the 45% in 1999. Hong Kong Department of Health (2002) also supported the proven benefits of regular physical activity, while physical inactivity was common in Hong Kong. Research supported the view that engaging in physical activity /exercise could improve one’s health and lower the health care cost. The purpose of the study is to: 1) establish a physiological profile; and 2) examine sport participation motives of 764 older adults (Male = 168; Female = 596) in Hong Kong. They were divided into three age groups: (a) 60-69, (b) 70-79, and, (c) 80 and older. Seven physical and motor ability tests were administered. The test items included: (a) body composition, (b) handgrip strength, (c) flexibility, (d) balance, (e) agility, (f) eye-hand coordination, and (g) cardiovascular fitness. 2X3 ANOVA and t-tests were used to analyze the data. Results revealed that the youngest group performed better in all seven-test items. Males performed better than females in body composition, handgrip strength, balance, agility, eye-hand coordination, and cardiovascular fitness scores. Participants who regularly participated in physical activities had better scores in balance, agility and cardiovascular fitness than participants who did not regularly participate in physical activities. The top five motives for exercise were (a) health, (b) enjoyment and confidence, (c) love to exercise, (d) killing time, and (e) social opportunity. The results of this study provide a baseline data for researchers and practitioners to enhance the development of physical activity for older adults in Hong Kong.
