Background: Thyroid hormone is a key substance in normal homeostasis, having variable influence on cell metabolism on different organs. Hypothyroidism is common, potentially serious, often clinically overlooked, readily diagnosed by laboratory testing, and eminently treatable. Aim: This study was conducted with the aim of finding the effect of regular physical exercise of medium-intensity on thyroid function in patients already undergoing treatment for hypothyroidism. Materials and Methods: A total of 20 ambulatory treated hypothyroid patients were included in the study. Serum samples were collected and evaluated for triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH) both before and after 3 months of daily 1 h physical exercise, from those patients doing exercise and from those who did not do any physical exercise. T-test was used to find a significant difference between the two groups. Results: Serum TSH was found to be significantly decreased in patients of regular exercise group postinterventionally (P < 0.001) when compared with nonexercise group (P = 0.43). Serum T3 and T4 were also found to be significantly raised in regular exercise group postinterventionally (P = 0.007 and P < 0.001 respectively) but not in nonexercise group (P = 0.92 and P = 0.73 respectively). On inter group comparison significant decrease in TSH was found in regular exercise group (P = 0.002) and significant increase was found in levels of T3 (P = 0.002) and T4 (P = 0.001) in regular exercise group. Mean weight was also found to be decreased in regular exercise group postinterventionally. Conclusion: Every hypothyroid patient should do regular physical exercise along with thyroxine replacement to improve thyroid function.
