A sample of 556 Chinese secondary school students participated in the research and completed Educational Stress Scale for Adolescents at the beginning of the semester and 3 months later. The results demonstrated that academic stress factors were positively related to less self-determined motivations except that worry about grades was positively related to more self-determined motivations within each time point. In addition, we found that academic stress negatively predicted more self-determined motivations but positively predicted less self-determined motivations, whereas worry about grades negatively predicted amotivation 3 months later. Meanwhile, the influence of amotivation on despondency was also found. These results suggest that academic stress can obstruct students’ participation in physical education through an impact on self-determined motivation. Our findings also indicate that self-determined students in physical education will seek academic achievement as well, which in turn improves students’ academic status.
