3.96) volunteered to participate in this study. In a fully randomised, each subject performed 10 4.75 kg, Vo2max 45.921.33 years, Weight 48Objective: To examine whether time of day significantly affects salivary IgA, cortisol, alpha amylase and total protein levels before and after submaximal swimming. Methods: Fourteen female swimmers (age 13‌IgA and a significant interaction effect of time of day by exercise on salivary alpha amylase -IgA in this study (p>0.05). Conclusion: These results suggest a significant circadian variation in the variables measured before exercise, with showing a significant effect on their acute responses to exercise except s-IgA/pro (p<0.05). There was no significant interaction effect of time of day by exercise on any salivary variables measured (p>0.05) except alpha amylase. No Significant relationship were observed between cortisol and s-IgA (p<0.05), saliva flow rate (p<0.05), alpha amylase (p<0.05), total protein (p<0.05) and s-IgA (p>0.05) but, in comparison with values before exercise, caused significant alterations in cortisol (p<0.05), S-IgA/pro (p<0.05). The exercise protocol did not significantly affect s-IgA (p<0.05), cortisol (p<0.05), saliva flow rate (p<0.005), alpha amylase (p<0.05), total protein (p<0.05) and s-IgA (p<0.05), S-factor analysis of variance with repeated measures. Results: Significant time of day effects (am and pm respectively) were observed in s- 200 m front crawl at 80 of their seasonal best time, with one minute rest between each 200 m, at 8:00 and 18:00 hours on two days aware. Timed, unstimulated saliva samples were collected before and after exercise. Saliva samples were analyzed by two
