Effect of Baseline Cortisol Level on Lipid Peroxidation Products in Young Female Swimmers

Research group: twenty-four and homogeneous female swimmers, who train swimming intensively and attend the Sports Championship School Complex. In this cohort, baseline serum cortisol levels were considered, and the athletes were divided into two groups: 1) Serum cortisol \230 ng/ml (high): n=10 In this study, the athletes were subjected to intensive swimming tests in breaststroke crawl (800m + 200m + 50m) with 15 minutes of active rest between test sections in the water. Blood samples took from the cubital vein at three time points: before stress test (pre-exercise), one minute after the end of the test (post-exercise), and after a 3-hour recovery period (3h recovery). Measurements morphology, 4-Hydroxynonenal (4-HNE), 8-isoprostane, cortysol levels were determined using ELISA kits.
