School-family cognitive discrepancies in the cultivation of children’s interest in sports: an exploratory study based on grounded theory

These studies preliminarily indicate that cognitive discrepancies can weaken the synergistic effects between schools and families in sports education practices, thereby reducing the effectiveness of fostering children's interest in sports. This, in turn, leads to decreased physical activity among children and exacerbates childhood obesity and overweight. Interventions targeting key nodes within the model may provide a new evidence-based fulcrum for the prevention of overweight and obesity.
