| Summary: | 碩士 === 國立臺灣體育學院 === 體育研究所 === 98 === This study was mainly to examine the differences of sedentary life-style and physical activity between students in primary schools. It also attempted to give a further study on the relationship between sedentary life-style and physical activity. Subjects were screened by in accordance with Body Mass Index (BMI). There were 111 boys and 54 girls from the obese group and 203 boys and 243 girls from non-obese group, total of 611 students participated in this study. Every participant should fill out the questionnaire toward sedentary life-style and physical activity. All of the participants’ performances were recorded in a three-day physical activity recalling table. The results were analyzed by SPSS 12.0 with significant level of α＝0.05. The results were as follows: a. Boys from the obese group had a significantly higher sedentary life-style level than those in non-obese group. Girls from the obese group had a significantly higher sedentary life-style level than those in non-obese group. b. Boys from the non-obese group had a significantly higher physical activity level than those in obese group. Girls from the non-obese group also had a significantly higher physical activity level than those in obese group. c. Boys from the obese group had a significantly higher physical activity level than girls in the obese group. Girls from the non-obese group had a significantly higher physical activity level than girls in the non-obese group. d. As for measurements of health-related physical fitness such as flexibility, explosive force, muscular endurance and cardiovascular endurance, boys from the non-obese group were significantly better than boys from the obese group. Girls from the non-obese group were significantly better than girls from the obese group in the measurements such as explosive force and cardiovascular endurance. e. Boys from the non-obese group had a positive correlation between sedentary life-style level and physical activity level. Girls from the obese group and non-obese group had a negative correlation between sedentary life-style level and physical activity level. High sedentary behavior may lead to low physical activity, obesity and inferior performance in health-related physical fitness. Developing a better understanding of sedentary behavior in relation to physical activity and obesity is critical for preventing and reducing obesity among children.
