Abstract: | The present study aims to evaluate the effect of selenium supplementation on lipid peroxidation and lactate levels in rats
subjected to acute swimming exercise. Thirty-two adult male rats of Sprague–Dawley type were divided into four groups. Group
1, control; group 2, selenium-supplemented; group 3, swimming control; group 4, selenium-supplemented swimming group. The
animals in groups 2 and 4 were supplemented with (i.p.) 6 mg/kg/day sodium selenite for 4 weeks. The blood samples taken from
the animals by decapitation method were analyzed in terms of erythrocyte-reduced glutathione (GSH), serum glutathione peroxidase
(GPx) and superoxide dismutase (SOD), and plasma malondialdehyde (MDA) and lactate using the colorimetric method, and serum
selenium values using an atomic emission device. In the study, the highest MDA and lactate values were found in group 3, while
the highest GSH, GPx and SOD values were obtained in group 4 (p < 0,001). Group 2 had the highest and group 3 had the lowest selenium levels (p < 0,001). Results of the study indicate that the increase in free radical production and lactate levels due to acute swimming
exercise in rats might be offset by selenium supplementation. Selenium supplementation may be important in that it supports
the antioxidant system in physical activity. |
