Table 1.
Blood levels of the biochemical parameters in the soldiers throughout 48 h of military survival training (n = 15).
| Survival Training Phase |
CK Activity [U/L] |
LOOHs [µmol/L] |
SOD Activity [U/gHb] |
GPx Activity [U/gHb] |
|---|---|---|---|---|
| P1 | 184.7 ± 66.1 a | 0.68 ± 0.26 a | 1196.9 ± 126.5 a | 62.5 ± 15.9 a |
| P2 | 145.6 ± 38.5 a | 1.00 ± 0.97 a | 1178.6 ± 191.9 a | 54.6 ± 15.7 a |
| P3 | 151.7 ± 58.3 a | 0.73 ± 0.38 a | 1201.0 ± 157.2 a | 36.4 ± 13.1 b |
| Main time effect | p = 0.13 | p = 0.33 | p = 0.91 | p < 0.0001 |
Values are mean ± SD. a,b differences in values of the analyzed parameters in the group (One-way ANOVA). Values (at different time points) that do not have a common letter differ significantly (p < 0.05). P1—phase 1 (before survival training); P2—phase 2 (after 24 h of survival training); P3—phase 3 (after 48 h of survival training); CK—creatine kinase; LOOHs—lipid hydroperoxides; SOD—superoxide dismutase; GPx—glutathione peroxidase; CK and LOOHs were measured in plasma; SOD activity was determined in erythrocytes; GPx activity was analyzed in whole blood; activities of antioxidant enzymes in erythrocytes and whole blood are expressed in U per gram of hemoglobin.
