Abstract:
The purposes of this study were to examine: the effects of goals and goal commitment on increasing physical activity levels; and whether goal commitment moderates the relationship between goals and increases in physical activity levels. A total of 69 middle-aged (16 male and 53 female) adults were asked to wear a pedometer and to maintain their daily routine minimum five days for a baseline assessment of physical activity. Participants were then randomly assigned into three different goal groups: 10%, 20% and 40% increase step counts from baseline measurement. The participants wore a pedometer and were asked to reach assigned goal. Then the participants’ goal commitment to the assigned goals was also measured. Results from a multiple regression analysis indicated that goal and goal commitment were significant predictors of increasing daily step counts. However, there was no significant interaction between goal commitment and goal on performance. With these findings, this study suggests that goal commitment is an independently important predictor for increasing physical activity in adults.
