RELATIONSHIP BETWEEN SUGJECTIVE USEFULNESS OF PEDOMETER AND STEP COUNTS, EXERCISE ADHERENCE IN THE COMMUNITY-DWELLING ELDERLY / 体力科学

ABSTRACT

The purpose of this study was to evaluate the association between subjective usefulness of pedometer and step count, exercise adherence, and the possibility of a pedometer helping exercise adherence.<BR>The subjects were 106 community-dwelling citizens (mean age±SD, 66±5) who were put on an individual exercise program in addition to walking. The targeted step count was 8000 steps/day. Every subject wore a pedometer that registers 7 days of physical activity.<BR>The rate of adherence was 98.1%, and about 73% of subjects answered that using a pedometer is useful for physical activity. There was no difference in exercise habit at baseline between subjects answering useful or not useful.<BR>Only in the case of females, was step count and prevalence of targeted 8000 steps significantly higher in the group who felt a pedometer was useful than in the group who didn't feel it useful. However, in the group of males who felt the usefulness of a pedometer, step count significantly increased during the 3 months. In addition, the females who reached their targeted step count performed better in the 10 m hurdle walk and 6 min walk than those who could not reach the targeted step count.<BR>The awareness of self-health wellness, without the anxiety of physical fitness and adherence to exercise was higher in the subjects who felt a pedometer was useful than in the subjects who didn't.<BR>The subjects who felt a pedometer was useful achieved their targeted number of steps and increased walking ability and tended to adhere better to physical activity.<BR>It is suggested that a pedometer motivates adherence to physical activity and is useful for helping exercise adherence in the future. However, we need a randomized control trial for determining the relationship between exercise adherence and using a pedometer.
