The effect of resistance exercise on muscular strength with the influence of growth hormone is well known. However, there is little information about its underlying effect on thyroid hormones (T3 & T4) and thyroid-stimulating hormones. Specifically, no research has been done on the effect of a resistance exercise intervention on thyroid hormone and thyroid-stimulating hormone serum concentration level among school children with intellectual disability in Ethiopian. The objective of this study was to investigate the effect of sixteen-week of a resistance exercise intervention on serum concentration level of thyroid hormones (T3 & T4) and thyroid-stimulating hormone (TSH) in school children with intellectual disabilities. In this study, eighteen school children with intellectual disabilities participated. The participants’ serum concentration level of triiodothyronine (T3), thyroxin (T4) and TSH were measured before and after a sixteen-week resistance exercise intervention and determined using quantitative determination of T3, T4, and TSH respectively. Paired t-test was used to analyze the pre-test and post-test data of thyroid hormones (T3 and T4) and TSH of the study. Aftersixteen weekof resistance exercise intervention, a significant mean score change was observed in the serum concentration level of thyroid hormones (p < 0.05) in T3 (p= 0.038), T4 (p = 0. 017) and TSH (p = 0.018). Our finding revealed that resistance exercise affects the serum concentration level of thyroid hormones and thyroid-stimulating hormones in school children with intellectual disabilities.
