Results
of our experimental program support the idea that properly selected exercises can improve the development of
particular
skills in children with intellectual disability. Limitations of this study pertain to the small sample size, as well as
difficulties
in controlling all factors that could affect the exercise process itself, such as motivation, interest in taking part in
the
program, health status. Furthermore, study results could not explain why there were no differences in improvement
among
children who exercised, related to their intellectual functioning. In that respect, further longitudinal monitoring is
required
to establish possible association of those factors.
