Acute and chronic effect of interval and continues resistance training on salivary IgA and cortisol levels in active young women

Abstract

The purpose of this study was to investigate the Acute and chronic effect of interval and continues resistance training on salivary IgA and Cortisol in active young women. Twenty one healthy female's participated voluntary in this study, Following anthropometric measurements session and determination of 1-RM, all subjects were randomly assigned to interval and continues training groups and a control one (each group n=7). Training groups performed 8 weeks of continues and interval strength training with progressive manners, while the control group did not participate in any exercises. Two acute resistance exercises performed before and after 48h of the last training session, salivary samples were taken before, immediately and after 1h recovery in acute sessions for training groups, but for control group only resting salivary samples before and after training periods were taken. Repeated measure ANOVA with between groups factors have been used for comparing training groups. If significant difference were found, Bonforoni post hoc test were used. Total body mass and percentage of body fat were not significantly changed either in control or training groups after training periods. Resting s-IgA training groups were increased significantly in comparison with control group (P=0.034), but cortisol had no changes. Also Interval and continues strength training to have no-significant effects upon the salivary IgA and cortisol acute responses. The data from the present study suggested that s-IgA and cortisol responses to low intensity progressive interval and continues resistance training had no different in acute responses to strength exercise, and different protocol with high intensity and volumes may be needed for making considerable differences in sIgA and cortisol levels.
