Abstract
All the major metabolic pathways are influenced by the thyroid hormone (TH) and the thyroid glands are responsible to secret these thyroid hormones (THs) which are very essential to maintain the normal metabolism (Park and Song, 2016). Vital role is played by these thyroid hormones in neural development, metabolism of carbohydrate, lipid and protein, growth and maturation of bones and cardiovascular and renal functions as well (Mondal et al., 2016) and (Samy, Ismail and Nassra, 2015). The physical exercise or swimming is known to increase the activity of thyroid glands and also increases the blood level of melatonin which is associated to raise the level of TSH (Thyroid Stimulating Hormone). Swimming exercise improves different nerve growth factors and angiogenesis and this encourages the researchers to study the effect of swimming exercise on function of thyroid stimulating hormones (TSHs). The effect of exercise on circulating thyroid hormones is still not clear through the studies and it is assumed that load of physical exercise shows effect on THs level and serum lipid profile in swimmers.
