The Effect of 8 Weeks of Core Stability Training on Static and Dynamic Balance In Mentally Retarded Children 8 to 10 Years

The aim of this study was to investigate the effect of 8 weeks of core stability training on static and dynamic balance in mentally retarded educable children eight to ten years. The population of this study was all of mentally retarded children of Mehr School in Momarekeh city and sample consisted 24 educable mentally retarded students, with mean and standard deviation for age (9.12±0.74years), height (121.1±8.6Cm) and weight (23.25±6.9Kg), who were healthy physically and voluntarily participated in this research. In the first preliminary assessment of the state of static and dynamic balance subjects, Sharpend Rombrg and get up and go tests respectively were used. the subjects were randomly divided into two equal experimental and control groups (n=12).The experimental group had eight weeks of core stability training with three sessions per week and each session lasted for 45 minutes. During this period, the control group did not perform any specific types of exercise. After eight weeks, both groups were participated in the post tests that were the same as the pretests. Data were analyzed through descriptive and analysis of covariance at the 0.05 level. The results showed significant difference in static balance with eyes open (P=0.000), eyes­ close (P=0.000) and dynamic balance (P=0.000) between the experimental and control group after eight weeks of core stability training. Finally, core stability exercises can improve static and dynamic balance mentally retarded children eight to ten years. Therefore, coach and teacher can use theses exercise to enhance the motor performance and welfare of mentally retarded children.
