Association between physical fitness, body mass index and intelligence quotient in individuals with intellectual disabilities

The effect of increasing exercise in the intellectually disabled community

BACKGROUND

Intellectually disabled individuals have been observed to lead sedentary lifestyles resulting in poor health. Physical fitness has been positively correlated to better health outcomes with small changes in fitness translating to major health changes among unfit older adults with intellectual disability. However, there is currently no literature on safe exercise regimens for the intellectually disabled population.

METHODS

In this article, a retrospective review was conducted using the Special Olympics Athlete database and analyzed the mean differences of various performance metrics based on self-reported exercise frequency.

RESULTS

These results demonstrated that those who exercised daily performed significantly better in flexibility, static balance and functional strength as compared to those who did not exercise. No statistically significant differences were found among athletes and self-reported exercise frequency for aerobic fitness.

CONCLUSION

Overall, these findings suggest that 3-6 days-a-week of moderate exercise would be a recommended exercise dose to see significant improvement in performance and physiological adaptations.

Effect of the environmental factor of coexistence on the physical condition of people with mild and moderate intellectual disabilities

BACKGROUND

The main objective of this study was to compare the physical condition of people with intellectual disabilities living in residential homes (RH; restricted residential environment) versus independent homes (IH; family houses while performing paid work). The effect of gender on physical condition was also evaluated separately for each group.

METHOD

Sixty individuals with mild to moderate intellectual disability, 30 living in RH and 30 living in IH, participated in this study. The RH and IH groups were homogeneous in terms of gender distribution (17 males and 13 females) and intellectual disability level. Body composition, postural balance, and static and dynamic force were considered as dependent variables.

RESULTS

The IH group performed better in the postural balance and dynamic force tests compared to the RH group, but no significant differences between the groups were observed for any body composition or static force variable. Women in both groups tended to have better postural balance than men, while men presented higher dynamic force.

CONCLUSIONS

The IH group presented a higher physical fitness compared to RH group. This result emphasises the need to increase the frequency and intensity of the physical activity sessions commonly programed for individuals living in RH.
