Physical Inactivity is a Type of Stress Resulting in Thyroid Gland Dysfunction
نویسنده
چکیده
Studies show that physical inactivity can influence functions of body glands. The main aim of this study was to determine the effects of physical inactivity on thyroid glandfunction in rats. Male Wistar rats were randomly divided into control and immobilized (8h/days for 8 days) animals of 10 in each group. After 8 days, blood samples were collected using cardiac puncture method. Following serum collection, TSH, T3 or T4 levels were measured by radioimmunoassay method. Data were statistically analyzed and compared between groups using ANOVA. The results indicated that serum T3 or T4 levels were significantly increased in immobilized rats compared with control animals (P<0.001). Serum level of TSH was not significantly changed compared with control rats. Our findings show that immobilization enhances thyroid function. Keywords— Immobilization, T3, T4, TSH, Rat.
