Popis: The aim of the study was to evaluate the effect of melatonin supplementation on antioxidant capacity and DNA damage in high intensity interval training (HIIT) athletes. A 2-week randomised, double-blinded, placebo-controlled trial with two groups was conducted. Placebo (PG) and melatonin (MG) (20 mg/d) athletes were monitored over a two-week period of HIIT and strength training. The total antioxidant capacity (TAC) and the glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were analysed in blood samples. DNA damage was measured in isolated lymphocytes by comet assay prior to and immediately after exercise. The supplementation increased plasma melatonin levels in the melatonin-treated group (p
