Effect of Zinc Administration and Exercise on Thyroid Hormone Level
Abstract
Background: Aim: To evaluate effect of zinc administration and exercise on thyroid hormone level in human body. Subjects and Methods: One hundred twenty healthy adults in age ranged 18-23 years of either gender were randomly assigned to either of 4 groups. Group I was sedentary groups given zinc, group II were given zinc only, group III were put on training only and group IV was sedentary group. The enzymatic calorimetric method was used for measurement of TSH, FT3 and FT4 levels. Results: The mean height in group I subjects was 176.2 cms, in group II was 176.4 cm, in group III was 176.9 cms and in group IV was 175.5 cms. Pre- test weight in group I was 76.5 kgs and post- test was 78.2 kgs, in group II was 75.8 kgs and 77.7 kgs, in group III was 76.4 kgs and 79.2 kgs and in group IV was 78.3 kgs and 77.6 kgs respectively. Pre- test and post- test TSH (uIU/mL) in group I was 2.54 and 2.43, in group II was 2.53 and 2.06, in group III was 2.62 and 2.10 and in group IV was 2.75 and 2.78 respectively. FT3 (pg/mL) level in group I was 3.77 and 3.56, in group II was 3.82 and 3.68, in group III was 3.75 and 3.50 and in group IV was 3.85 and 3.77 respectively. FT4 (ng/dL) level was 1.57 and 1.46 in group I, 1.56 and 1.34 in group II, 1.50 and 1.32 in group III and 1.52 and 1.54 in group IV. Conclusion: Zinc supplement and exercise can lead to the alteration of thyroid level in athletics.
