The purpose of this research was to examine the effect of core training on equilibrium sensory function, flexibility, lumbar muscle function and visual analogue scale (VAS) in students with intellectual disability. 20 subjects were divided into control (n=10) and exercise (n=10) groups. Exercise group was given to utilizing core training with the period and frequency of 40 minutes, 3 days a week for 12 weeks. Equilibrium sensory function, flexibility, lumbar muscle function and VAS of all subjects were measured at before and after the program participation. Consequently static balance, flexibility, muscle strength, muscular endurance, and VAS were significantly enhanced within exercise group after application of exercise program. In summary, when considering the above results, we conclude that core training may improve the levels of equilibrium sensory function, flexibility, lumbar muscle function and VAS in exercise participants with intellectual disability.
