TBARS: thiobarbituric acid reactive substances; MDA: malondialdehyde; CD: conjugated dienes; CAT: catalase; GPx: glutathione peroxidase; SOD: superoxide dismutase; HGB: haemoglobin; HCT: haematocrit. The values are expressed as means ± standard deviations (SD). †Statistically significant difference compared with measurement after the 1st HBO session (†P ≤ 0.05).
