Background and Objectives: In the present study, the effect of acute aerobic exercise on enzymatic and non-enzymatic salivary antioxidants variations in non-athlete men, was investigated.

Methods: In this experimental study, 25 male non-athlete collegiates (age, 21.2±1.6 years; weight, 68.62±10.1kg; body fat, 16.75±2.9%; and Vo2 max, 37.54±2.4ml/kg/min) participated voluntarily in this study. Saliva samples were collected in three phases (before, immediately, and 1 hour after running) on treadmill according to Astrand test. The activity of peroxidase and catalase, and concentration of uric acid were measured by laboratory methods. Then, to assess the obtained changes, repeated measures statistical test, and in case of significance, post-hoc Bonferroni test were used for pairwise comparing of the measuring phases at the significance level of p≤0.05 used. 

Results: The activity of peroxidase significantly increased immediately and 1 hour after exercise compared to the baseline; Also, the concentration of uric acid significantly increased after aerobic exercise, but catalase enzyme activity significantly decreased after aerobic exercise (p<0.05). No significant change was observed in saliva flow rate after exercise.

Conclusion: According to the findings of this study, aerobic exercise causes the production of free radicals, and salivary antioxidant system increases as the body biological response to neutralize and counteract the damaging effects of free radicals.



Keywords: Antioxidant, Free radical, Exercise, Saliva flow rate.
