By the means of literature study, the paper sums up the physical activity intervention in adolescents and children based on schools at home and abroad. The results reveal that child and adolescent period is a critical period for physical development and the intervention based on schools is quite effective. Both the intervention at home and abroad lays emphasis on the systematization of the intervention, though the intervention comes from different departments. In foreign countries, the departments concerned pay attention to students' independent participation, diversified means, the long-term healthy behavior of students and the improvement of lifestyles. While in China, we pay more attention to the contents and time guarantee of students' physical activities and the monitoring of exercise load, especially the targeted intervention. And the effect of the intervention is obvious. |
