In this study, it is aimed to investigate the relationship between the attitudes of students studying in secondary school to physical activity and their school life satisfaction. The relationship between middle school students' attitudes towards physical activity and school life satisfaction was tested by the structural equation model. A total of 299 students who study at secondary schools affiliated to Çanakkale central schools, 53.2% (n = 159) of whom are male and 46.8% (n = 140) of female, are the research group. Attitude scale to physical activity and school life satisfaction scales were used as data collection tool in secondary school students. It has been observed that socialization and Self-Trust dimensions, which are the sub-dimensions of attitude to physical activity, affect school satisfaction positively and significantly, and are statistically significant. As a result, physical activity environments affect students 'feelings of socialization and self-confidence positively, which is thought to affect students' school life satisfaction positively. To gain the habit of doing physical activities in schools, it can be suggested to increase the physical education lesson hours and to direct them to extra sports activities.
