Abstract

Secretory IgA (S-lgA) levels in stimulated salvia were measured before and after a maximal treadmill test in a population of 175 young adults (84 men, 91 women). Habitual physical activity levels of this population were measured by a standardized interview, and scores were obtained for the amount of time and intensity of sports activities and total activity.

Before the maximal treadmill test, men and women showed no statistically significant differences in the salivary concentrations of S-lgA, but the concentration of S-lgA in women decreased and in men increased statistically significantly (P < 0.05) after the treadmill test.

Only women showed a significant correlation between absolute values of S-lgA and the weekly amount of time spent on sports activity measured by a standardized interview expressed in minutes per week.

Key words

secretory IgA - stimulated saliva - strenuous exercise - habitual activity - young men and women
