Physical education teachers are the practitioners of physical education curriculum reform who work at the front line of teaching, and their innovation behavior play a crucial role in promoting the smooth implementation of physical education curriculum reform. This study uses goal orientation theory as a theoretical basis to explore the mediation effect of learning goal orientation in the influence of perceived organization support on physical education teachers' innovation behavior. A total of 402 valid questionnaires were collected from physical education teachers in 40 schools at the basic education level in China, and the relationship between the variables was tested using structural equation modeling. The findings showed that physical education teachers' perceived organizational support had a positive effect on learning goal orientation and innovation behavior. Physical education teachers' learning goal orientation significantly influenced their innovation behavior. Additionally, learning goal orientation partially mediated the relationship between perceived organizational support and innovation behavior.
