청소년들의 체지방량과 동기적 행동규제가 신체활동에 미치는 영향

The current study investigated the differences in physical activity and motivational behavior regulations of adolescents in the different weight condition. In addition, the study examined the influence of body fat and motivational behavior regulations on physical activity and a moderating effect of body fat on the relationship between physical activity and motivational behavior regulations. A total 487 adolescents were selected from C middle school located in northen Seoul (normal-weight group : 255, overweight group : 141, obesity group :91). Leisure-time Physical Activity Questionnaire and Behavioral Regulation for Exercise Questionnaire were applied to measure study participants' physical activity and motivational attributions. There were significant differences in levels of physical activity and motivational behavior regulations among normal-weight,overweight, and obese adolescents. In addition, results indicated that physical activity, body fat, and motivational behavior regulation were substantially correlated. Results identified that body fat and identified regulation, external regulation, and internal regulation were significant to explain physical activity, but body fat was not significant to moderate the relationship between physical activity and motivational behavior regulation.
The current study offers the meaningful data in understanding of the motivational attributes most likely to contribute to initiation and long-term adherence of physical activity among overweight and obese adolescents.
