Background and Objectives: parental support is an important predictor of adolescents' participation and levels of leisure-time physical activity. This study aimed to investigate the structural relationships between parental support, restructuring ability, subjective norm and leisure time physical activity. Materials & Methods: During a descriptive research of the correlation type, data were collected using questionnaires of leisure physical activity (Godin, 2011), subjective norm (Kim et al., 2019), restructuring ability (Xie et al., 2018a) and perceived parental support (Xie et al., 2021),641 adolescents between 12 and 18 years of age, boys and girls, who had a history of physical activity in their leisure time, were collected from May to June 2022 by purposive sampling and analyzed with SPSS 25 and SmartPLS 3 software. Results: Path analysis shows that all the hypotheses were statistically significant at the P<0.05 level. specifically, the subjective norm had a positive effect on the restructuring ability and the of leisure physical activity adolescents (P<0.05). In addition, the restructuring ability had a positive effect on the subjective norm and leisure physical activity adolescents (P<0.05). Finally, parental support had a positive effect on adolescent's restructuring ability, subjective norm and leisure time physical activity (P<0.05). The coefficient of determination for leisure time physical activity was equal to 27.8% and it shows the concept that the variables of parental support, subjective norm and the restructuring ability to rebuild together have predicted 27.8% of leisure time physical activity. but both variables of parental support and leisure time physical activity predict a total of 52.6% of adolescents' leisure time physical activity, the share of leisure time physical activity was higher than parental support. Conclusion: The results emphasize the importance of parental support for adolescents' leisure time physical activity and helping adolescents to develop the restructuring ability and subjective norm as a way to promote leisure time physical activity among adolescents. As a result, such parental support, especially for adolescent boys and girls with poor health status and high body mass index, increases the leisure time physical activity of adolescents and improves their overall health.
