Serum oxidative stress markers and vitamin C status in experimental groups before vitamin C oral supplementation.
| Acute exercise (n = 30) |
Regular training (n = 30) |
P value | |
|---|---|---|---|
| MDA (µmol/L) | 3.04 ± 1.48 | 4.26 ± 0.97 | 0.001 |
| Vitamin C (µmol/L) | 55.4 ± 11.93 | 62.27 ± 9.68 | 0.017 |
| Asc (µmol/L) | 24.13 ± 8.80 | 21.23 ± 7.57 | 0.181 |
| DHA (µmol/L) | 31.60 ± 10.09 | 41.03 ± 8.76 | <0.001 |
| Ratio of DHA/Asc‡ | 1.62 ± 0.90 | 2.16 ± 1.02 | 0.022 |
| MPO (U/L)‡ | 45.80 ± 26.89 | 68.83 ± 13.65 | <0.001 |
Serum malondialdehyde (MDA), total vitamin C, ascorbic acid (Asc), dehydroascorbic acid (DHA), and myeloperoxidase activity (MPO) in acute exercise group were compared to values in regular training group before vitamin C oral supplementation. Differences between groups were tested by independent-samples t-test and Mann-Whitney test (‡), respectively.
