Effects of Long-term Kin-ball Program on Changes in Physical Coordination of Students with Intellectual Disabilities

This study was conducted to investigate the effect on changes in phisical coordination after applying the Kin-ball program for 30 weeks to students with intellectual disabilities. The subjects of this study were eight intellectually disabled students at S Middle School in Y city of Gyeong gi province. It was conducted after obtaining consent from the subjects and their parents to participate in the study. The Kin-ball program was designed step-by-step with a frequency of exercise twice a week for a total of 30 weeks. To evaluate the physical coordination of the study subjects, the Korean version of the Oseretsky Test of Motor Proficiency was conducted, and static coordination, hand movement coordination, and general movement coordination tests were conducted among various test items. The physical coordination test was measured a total of 7 times at 5-week intervals. After the Kin-ball program was terminated, repeated measures ANOVA was conducted to analyze the difference in changes in physical coordination. The main results are as follows. Static coordination was found to increase significantly after 25 and 30 weeks compared to before, after 5 weeks, after 10 weeks, and after 15 weeks. Hand movement coordination showed a significant main effect (p.001), but a post-hoc analysis showed no significant difference. General coordination was found to increase significantly after 25 weeks and 30 weeks compared to before, after 10 weeks, after 15 weeks, and after 20 weeks. Changes in physical characteristics significantly increased height after 30 weeks compared to before(p.01). In summary, long-term application of the Kin-ball program to students with intellectual disabilities has a positive effect on physical coordination.
