title: Oxidation-reduction processes in ice swimmers after ice-cold water bath and aerobic exercise.
abstract: The effect of an ice-cold water (ICW) bath as a recovery intervention from aerobic exercise on the oxidant-antioxidant balance in healthy ice swimmers was determined. Twenty ice swimmers aged 31.2 ± 6.3 years performed a 30-min cycloergometer exercise test at room temperature (20°C, RT), followed by recovery at RT or in a pool of ice-cold water (ICW bath, 3°C, 5 min). Blood for laboratory assays was collected from the basilic vein two times: before the exercise (baseline) and 40 min after the RT or ICW recovery. The concentrations of plasma and erythrocytic thiobarbituric acid reactive substances (plTBARS and erTBARS, respectively), serum concentrations of 8-iso-prostaglandin F2α, 4-hydroxynonenal and malondialdehyde, along with the erythrocytic activities of catalase (CAT) and superoxide dismutase (SOD), as well as the serum level of total antioxidant capacity, were assessed. No statistically significant changes were observed. However, a statistically significant negative linear correlation between the erTBARS concentration and the SOD activity was found 40 min after the combination of exercise/RT recovery (r=-0.571, P<0.01). The baseline CAT and SOD activities were also linearly correlated (r=0.469, P<0.05). Both the 5-min ICW bath and the 30-min aerobic exercise have practically no impact on the oxidant-antioxidant balance in healthy ice swimmers.
