Methods: A total of 30 mild intellectual disability (MID) individuals between 15-18 age groups participated the study. Bruininks-Oseretsky Test of Motor Pro?ciency-Second Edition (BOT-2)- Short Form were performed to determine basic motor characteristics of children. BOT-2-Short Form was applied to the participants before and after the ten-month swimming exercise program (60 dk/ 3 days /10 week). Results: According to research findings, in terms of body weight, manual dexterity, speed and agility, upper limb coordination, and BOT-2 total point parameters, there was no statistically significant difference found between groups, measurements (pre-test and post-test), groups and their measurements (p>0.05). In terms of fine motor precision, and fine motor integration parameters, while there was no statistically significant difference found between groups (p>0.05); a significant statistical difference was found between measurements (pre-test and post-test), groups and their measurements (p<0.05). In terms of bilateral coordination parameter, while there was no statistically significant difference found between measurements (pre-test and post-test), groups and their measurements (p>0.05); a significant statistical difference was found between groups (p<0.05). In terms of balance parameter and strength, while there was no statistically significant difference found between groups, groups and measurements (p>0.05); statistically significant difference was found between measurements (pre-test and post-test) (p<0.05). Conclusion: Consequently, regularly applied exercise programmes improve life quality level of individuals with MID by contributing to their motor development level. http://pubs.sciepub.com/ajssm/3/5/1/ajssm-3-5-1.pdf motor development intellectual disabilities exercise
