- PURPOSE
This study explored the feasibility of a 12 week self-efficacy based exercise intervention for overweight and obese college students.
METHOD
A repeated measure, 4-group randomized controlled design was used. Students were recruited from two universities, in Seoul, Korea using: (1) flyers either on the campus bulletin boards or in campus restrooms; (2) advertisement on campus e-board; and (3) self-referral. Inclusion criteria were: (1) Korean college students aged 18 to 29; (2) BMI >23; (3) viscerally obese; and (4) accessible to a phone and a computer. Participants completed three self-reported questionnaires: socio-demographic questionnaire (at the baseline), Exercise Self-Efficacy Scale (at the baseline and 12th week), and Physical Fitness sub-subscale (at the baseline and 12th week). Additionally, physiological data (height, weight, blood pressure) were collected at the baseline and 12th week. Descriptive statistics and a two-way mixed ANOVA were performed using SPSS12.0.
RESULTS
No significant group difference was observed. However, students with increased exercise self-efficacy during the program showed better physical fitness in the 12th week. When students' physical fitness was enhanced, the physiological factors were improved.
CONCLUSIONS
Self-efficacy based exercise intervention may be applicable and acceptable to the college students. It is necessary to conduct a replicated study with a larger sample and an elongated intervention period.
