Abstract:
<em>Introduction:</em> Yoga may have a role in revitalizing thyroid function there are few studies on the effects of yoga on thyroid function. The aim of present study was to investigate the effect of eight weeks yoga program on triiodothyronine (T<sub>3</sub>), thyroxine (T<sub>4</sub>) and thyroid stimulating hormone (TSH) in young sedentary women.<br /> <em>Material & Methods:</em> Twenty sedentary women aged between 20 to 40 years old participated in this study as the subject. The subjects were divided into yoga group (n=10) or control group (n=10) randomly. The subjects in the yoga group underwent 90 min hatha yoga practices daily, 3 times a week for 8 weeks, whereas control group continued their usual routine activities. Basal level of serum T<sub>3</sub>, T<sub>4</sub> and TSH were measured before commencement and after 8 weeks of yogic training.<br /> <em>Results:</em> The results indicated that T<sub>3</sub> decreases significantly in the control group (t = ‒ 2.02, P = 0.05); however, there was no significant change in T<sub>4</sub> (t = ‒ 0.3, P = 0.7) or TSH (t = 0.15, P = 0.8) in any of the two groups over the 8 weeks period.<br /> <em>Conclusions:</em> In summary, the results suggest yoga training utilized in this study had not significant effect on thyroid function in sedentary women.

The effect of eight weeks yoga program on the thyroid function in middle-aged women Azam Salehi Received: 6 October 2018 / Accepted: 16 December 2018 (*) MS in exercise physiology; Education Administration in Gachsaran, Iran.
The aim of present study was to investigate the effect of eight weeks yoga program on triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH) in young sedentary women.
Conclusions: In summary, the results suggest yoga training utilized in this study had not significant effect on thyroid function in sedentary women.
They reported that there is no significant change in TSH, T3 and T4 level after the practice of yoga or traditional physical exercise and control groups during three different (at 0, 3 and 6 months) periods (15).
Recently, Chatterjee and Mondal (2017) were studied the effect of combine graded yoga program on the basal level of thyroid hormones in healthy middle-aged adults.
They reported that twelve weeks of yogic training produces a significant increase in serum TSH level for male and decrease in T3 and T4 for both male and female groups as compared to their baseline data, whereas no such changes were observed in the control group during these 12 weeks (9).
Thus the present study was done to examine the effect of eight weeks yoga program on T3, T4 and TSH in sedentary women.
The aim of the present study was to examine the effects of 8 weeks yoga training on the thyroid function in sedentary women.
