The Research Of The Coordirection Motor Proficicency And Development Character Of Intellectual Disability Between6Years Old And17Years Old

The aim of the present study was to investigate the coordination motor proficiency and development character of Intellectual Disability between6-17years old. For that purpose, the coordination subtest of the Test of Motor Proficiency was administered to1549students with ID, from which1175effective sample was collected, the effective rate is75.86%. For the data analysis, both MANOVA and EMMEANS were applied on the seven item scores combine with the Profiles, totally and respectively.The results were as follows:(1) both the age and level were found to have a significant effect on item scores. Age and performance were positively related, and Barriers degree more light, the higher the score.(2)Significant gender differences were found on the "Dropping and Catching a Ball-Both Hands"、"Dribbling a Ball-One Hand’"、"Dribbling a Ball-Alternating Hands"、"Catching a Tossed Ball-Both Hands" items all of which are upper-limb coordination, and males were much better than females; while females were little better than males on the Bilateral Coordination items("Touching Nose with Index Fingers-Eyes Closed"、"Jumping in Place-Opposite Sides Synchronized"、"Tapping Feet and Fingers-Same Sides Synchronized "),but it was not of great significance.(3)"Touching Nose with Index Fingers-Eyes Closed" and "Tapping Feet and Fingers-Same Sides Synchronized" motors got higher score level during6-9ages, and the score "10-13ages" was much higher than "6-9ages" with a significant effect, while the score "14-17ages" only was little higher than "10-13ages" without a significant effect.(4) Compare with that two items,"Dropping and Catching a Ball-Both Hands’、" Dribbling a Ball-One Hand"、"Dribbling a Ball-Alternating Hands"、" Catching a Tossed Ball-Both Hands" items got lower score during6-9ages, and the score of "10-13ages" was much higher than "6-9ages" with a significant effect, the score "14-17ages" also was much higher than "10-13ages" and "6-9ages" with a significant effect.(5)"Jumping in Place-Opposite Sides Synchronized" is the most difficult items, which has lower score form age6to age17. And the score "14-17ages" was much higher than "10-13ages" and "6-9ages" with a significant effect, while the score of "10-13ages" was little higher than "6-9ages" was not of great significance, which indicated that " Jumping in Place-Opposite Sides Synchronized" was relatively slow growth.
