The Effect Of Extracurricular Physical Activities In The Development Of Coordination Ofchildren Aged 7 To 9 Yearsold

Abstract

PURPOSE: The purpose of this study was to assess the effects of extracurricular physical activities on the physical coordination in children aged 7-9 years. METHODS: A sample of 120 children aged 7-9 years (52% boys) was enrolled for a 12-week experimental intervention study. The sample was divided into an experimental group (58 children) and control group (62 children) by random number method. The experimental group participated in extracurricular intervention courses twice a week for 1 hour. The content of the course was mainly game, medium exercise intensity. The control group did not participate in the extracurricular exercise. The "Chinese Children Coordination Test "(CCCT) developed by the project team was used to conduct the coordination test before and after the experiment. The raw data was standardized and compared according to age and gender. RESULTS: After 12 weeks of extracurricular intervention, the results showed that the scores of the experimental group in the transfer coordination (t=2.89, p<0.05), click-to-click (t=2.76, p<0.05), climbing obstacles (t=4.47, p<0.05), and rolling skills (t=3.81, p<0.05) were significantly higher than the control group. The experimental group was significantly higher than the control group (t=2.90, p<0.05) in the standardized comprehensive score. CONCLUSION: Extracurricular physical activity intervention could significantly improve the coordination ability of children, and the density of extracurricular physical activities should be strengthened in this age group.
