Objective:
To study the effect of the submarine training on the antioxidant ability of the submarine men.
Methods:
50 sea-training submarine men, 50 land-training submarine men and 50 resting submarine men were randomly selected from some submarine troops. The blood routine, the total antioxidative capacity (T-AOC), the content of malondialdehyde (MDA) and the levels of IFN-gamma in blood plasma, the hemolytic degree of RBC, the proliferation of peripheral-blood lymphocyte (PPL) of them were detected in each group.
Results:
The T-AOC of the sea-training submarine men, the land-training submarine men and the resting submarine men significantly increased by turns [(15.38 +/- 3.11), (18.81 +/- 2.45), (20.93 +/- 2.95) U/ml], but MDA and the hemolytic degree of RBC significantly decreased by turns [(2.56 +/- 0.70), (2.12 +/- 0.53),(1.77 +/- 0.56) nmol/ml and 25.72% +/- 1.67%, 21.45% +/- 1.02%, 18.28% +/- 1.37%] (P < 0.05). Compared with the land-training submarine men and the resting submarine men, IFN-gamma [(31.89 +/- 3.52) pg/ml] and the proliferation of PPL of the sea-training submarine men were significantly lower, whereas the red blood count (RBC) and hemoglobin (Hb) were significantly higher (P < 0.05).
Conclusion:
Submarine training, especially sea training, may decrease the antioxidant ability.
