The Effect of Parental Physical Activity on Children's Physical Activity: the mediating role of children's perceptions of parental support

 The main purpose was to investigate the effect of parental physical activity on children's physical activity: the mediating role of children's perceptions of parental support. The statistical population consisted of 9-11-year-old male and female students in Tehran and their parents (299610). Based on Morgan table, 384 students were selected and 400 questionnaires were distributed through cluster sampling. In this study, physical activity questionnaires for children of Kowalski et al. (1997), children's perceptions of parental support Wilk et al. (2018), and Physical Activity for parental of Craig et al.(2003)questionnaires were used. Results showed that parental physical activity (β = 0.12, t = 1.19) had no significant effect on children's physical activity. However, parental physical activity (β = 0.23, t = 2.36) on children's perception of parental support, and children's perception of parental support (t = 4.51, β = 0.39) on children's physical activity had a significant positive effect. Finally, the mediating role of children's perceptions of parental support on the impact of parental physical activity on children's physical activity was confirmed and the research model showed a good fit.
