    Effects of Aerobic Exercise on Oxidant/Antioxidant Status in Obese Boys: A Controlled Trial
    (Gaziantep İslam Bilim ve Teknoloji Üniversitesi, 2021) Satılmış, Nuray; Çimen, Leyla; Çetin, İhsan; Polat, Yahya; Çimen, Behzat
    It is unclear how aerobic exercise program effects oxidative stress and antioxidant defense parameters in obese children; therefore, our objective is to examine the effects of aerobic exercise on parameters of oxidative stress and antioxidant in obese boys. Our study included 10 obese boys, aged from 13 to 15, and 10 healthy boys as control group. Before and after exercise, 10 ml blood specimens were taken from the obese boys, who exercised 3 days/week for 12 weeks. 10 ml blood specimens were also taken from the health control group. The oxidative stress and antioxidant defense parameter levels in blood samples were measured for both groups. In our study, it was found that control group and obese children after aerobic exercise had significantly higher superoxide dismutase, catalase, glutathione peroxidase and paraoxonase-1 values than those of obese boys before aerobic exercise. On the other hand, it was found that after aerobic exercise, control group and obese children had significantly lower malondialdehyde, nitric oxide and carbonyl values than those of obese boys before aerobic exercise. When these findings are taken into account, it may be suggested that aerobic exercise regulated oxidative stress and improved the state of antioxidant status in obese boys.

    The Effects of Aerobic Exercise on Thyroid Hormone Levels in Obese Boys
    (2020) Satılmış, Nuray; Çimen, Leyla; Çetin, İhsan; Polat, Yahya; Çimen, Behzat
    Aim: Although beneficial effects of physical exercises on adulthood obesity are well known, it is unclear how physical exercises affect thyroid hormone related body composition, basal metabolic rate and thermogenesis in obese children. Our objective is to examine the effects of physical exercise program on 3-5-3’triiodothyronine (T3) and 3-5-3’-5’tetraiodothyronine (T4) in obese boys. Materials and Method: Our study consisted of 10 obese boys (aged from 13 to 15) and a control group of 10 healthy boys age and gender matched. Before exercise program, 10 ml blood samples were taken from the obese and control group boys; and 10 ml blood samples were taken from the obese boys after program exercise 3 days/week for 12 weeks. The lipid profiles, creatine kinase (CK), creatine kinase-MB, T3 and T4 levels in blood samples were measured for both groups. Results: In present study, it was found that control group and obese boys after aerobic exercise had significantly higher T3 and T4 levels (1.63±0.17; 9.80±0.93 and 1.70±0.10; 10.1±0.54, respectively) and significantly lower CK levels (142.7±4.11 and 151.8±3.70, respectively) than those of obese boys before aerobic exercise (1.19±0.81; 7.37±0.47 and 165.3±2.49, respectively). Furthermore, it was found that aerobic exercise significantly decreased triglyceride and cholesterol levels in obese boys (104.0±3.77 and 193.7±2.90, respectively). Conclusion: When these findings are taken into account, it may be suggested that aerobic exercises can help with the improvement of decreased thyroid hormone levels which may be cause a weight increase together with a decrease in basal metabolic rate and thermogenesis in obese boys.
