Abstract
The purpose of this study was to examine the effects of physical exercise programs on individuals with intellectual disabilities (ID). This meta-analysis analyzed 67 effect sizes and 14 studies and calculated the standardized mean difference in effect size. The unit of analysis for overall effects was the study, and the sub-group analysis focused on effect size using a random effects model. The effect size of exercise programs was positive with a 0.41 standard deviation. The professional/scholastic measure was the most effective program, whereas the biometric and body composition effects were trivial. This study showed that short-duration exercise programs were more effective than those of longer duration, and an exercise program that runs 4 times per week had a better effect than one that runs 3 times per week. The most effective length of session for exercise was 31-60. min, and exercise was more effective for older people than for younger people. Amidst a growing variety of studies of physical exercise programs for individuals with ID, this meta-analysis indicated the present status and future direction of studies on physical exercise programs for individuals with ID. The limitations and implications for practice and theory were discussed.
