Abstract
The purpose of this research was to study the effects of exercise program participation on the personal factors of exercise adherence promotion in the middle-aged and elderly by comparing a group and individual exercise program. The personal factors for promoting exercise adherence, the four domains (i, e. initiative attitude, achievement satisfaction, self-recognition, and intrinsic motivation), were hypothesized. Two groups of middle-aged and elderly subjects, who volunteered to participate in different 6-month exercise programs, were examined. Group 1, 33 subjects (aged 67.7 ±4.3 years : mean±SD), participated in a program consisting of an individual exercise program (combination of endurance and resistance exercise, e. g. cycling exercise, dumbbell and machine exercise, once a week) and group exercise program (e, g. dance and ball game, once a week) . Group 2, 27 subjects (aged 65.2±4.Ovears), participated in the same individual exercise program twice a week. After the 6-month exercise program, significant improvements in group 1 were found in the selfassessment of activity score of the initiative attitude domain, the achievement satisfaction score including enjoyment, achievement and satisfaction, and the self-recognition score representing competence. In group 2, the mastery score in the intrinsic motivation domain was reduced, and the curiosity score in the same domain and the achievement score in the achievement satisfaction domain tended to decrease. These results show that a group program might have a more significant effect on the personal factors hypothesized to promote exercise adherence in this study. Hut there should be follow-up study on the subjects to determine the effectiveness of the program over the long term.
