The purpose of this study was to investigate the use of a pedometer, goal setting and prompting to increase physical activity in women 30-60 years of age that were not already enrolled in a formal exercise program. Thirty-eight women were recruited to participate in the eight-week study. Each participant wore a Yamax pedometer (SW-200) each day for the duration of the study and recorded daily step counts on the log provided. The first two weeks of the study determined baseline data. For the remaining six weeks, the participants were randomly assigned to a control group (n=12), experimental group 1 (n=13) or experimental group 2 (n=13). The control group was asked to record steps daily. Experimental group 1 was given an individualized goal in steps per day to achieve by the end of the eight-week study. Experimental group 2 was also given an individualized goal in steps per day to achieve by the end of the study and was contacted weekly to assess progress and give encouragement. Both experimental groups were encouraged to set progressively higher goals bi-weekly to work their way up to their final goal. Three by two repeated measures analysis of variance found a significant interaction effect [F (2, 35) = 4.45, p = .019, η2p = .20] between baseline and intervention on mean steps∙day-1. Simple main effects tests found a significant increase in step counts [F (1, 35) = 19.52, p < .001] within experimental group 1 from baseline 6538 steps∙day-1 (SD 3241) to intervention 8585 steps∙day -1 (SD 3854). In addition, simple main effects tests found a significant increase in step counts [F (1, 35) = 28.92, p < .001] in experimental group 2 from baseline 8161 steps∙day-1 (SD 1517) to intervention 10653 steps∙day-1 (SD 2432). There was no significant difference within the control group [F (1, 35) = 1.43, p = .240] from baseline 7971 steps∙day-1 (SD 1817) to intervention 8548 steps∙day-1 (SD 1670). For experimental group 1, 69% of participants reached their individual step goal, while 92% of experimental group 2 achieved their target. This study demonstrates the potential to increase daily physical activity in individuals with the use of pedometers, goal setting, and prompting. From this investigation, it is evident that both goal setting and frequent prompting are beneficial in increasing physical activity in programs using pedometers. Further, the findings suggest that individualized goal setting plays the most significant role in accomplishing this task. Keyword(s): exercise/fitness, physical activity, wellness/disease prevention
