The Study Of The Impact On The Balance Of Core Strength Exercise For The Moderate Retarded Children

Since the 60s of the 20th century, the special education has made great breakthroughs on the building of the theory, so it changed the subordinate status of general education. But before the main objects of special education were children with vision and hearing impairment, and the education of children with intellectual disabilities started in 1979, after the development of three decades nearly, which has become the fastest areas in the special education. However, the education of children with intellectual disabilities is not comprehensive, whether within the education system, or physical education system, the physical education of children with intellectual disabilities is not included comprehensively, and the study on increasing physical, improving exercise capacity and the ability of social adaptation through sports participation is rare.In this study,the author has a tracking observation for the students in Yu Zhi school of Xihu District Nanchang, Jiangxi Province for one and a half years,20 moderate retarded students in lower grades of them with 9-13 year-old had core strength training for a period of 12 weeks, and indicators of static (single-foot stance with eyes closed, force platform tests) and dynamic balance (vestibular stability test, the straight line test) are tested and analyzed before and after exercise. Then, on the impact of core strength training for mentally handicapped children, school teachers and parents of the objects were investigated, and made a simple evaluation.The major findings were summarized as follows:1) The difference of the balance among moderate mental retardation groups shows very different.2) Core strength training can improve the moderate retarded children's static and dynamic balance ability effectively, that is single-foot stance with eyes closed and the straight line test before and after the experiment both showed a significant difference.3) The force platform test of the objects'static balance has shown that there were significant differences between their feet, and the left foot is better than the right.4) Core strength training significantly improved the trajectory length, the average swing speed and 95% of the elliptical area of the objects'right foot.3) The core strength exercises have a stronger sensitivity on vestibular stability of retarded children in lower grades.
