The purpose of this investigation was to examine the relationship between physical activity patterns, age and Body Mass Index (BMI) in physically active elderly women. In ninety-four elderly Korean women, the number of steps taken per day and the time spent engaged in physical activity of light-, moderate- and vigorous-intensity were determined. The number of steps did not significantly differ according to age or BMI. However, time spent in moderate-intensity physical activity significantly decreased as BMI increased (P=0.049 F=3.120) and age increased (P=0.002, F=5.035). Thus, active elderly individuals should be encouraged to spend time doing moderate-intensity physical activity rather than worry about the number of steps taken each day in order to prevent obesity and an age-related decline in regular physical activity.
