Abstract

Introduction:The aim of this study was to assess the effect of concurrent training on salivary IgA, cortisol, DHEA concentration and DHEA:cortisol ratio in untrained female. Materials and Methods: Thirty-nine untrained volunteer female students (aged 24±2.5 yr, height 161 ± 8.2 cm, weight 56.8±14.61 kg) were selected objectively and were randomly divided into four groups: Control (C n=9), Endurance (E n=10), Resistance (S n=10) and the Concurrent (SE n=10) groups. E training consisted of running 65% MHR for 16 minutes during the first week, reaching 80% MHR for 30 minutes during the 8th week. S training consisted of four leg-press, bench-press, pull down curls, and legs curls. During the first week, the intensity of training was at 50% 1RM in two sets with 10 repetitions, and was the increased to 80% 1RM in 3 sets and 6 repetitions, during the 8th week. The SE training included a combination of two S and E trainings in the same manner for each respective group. Before and after 4 and 8 weeks of trainings, at 8 o’clock in the morning unstimulated saliva samples were collected and measured by ELISA. Results: ANOVA for repeated measures showed, that the S group, compared to other groups, had significant difference in IgA,DHEA and DHEA: cortisol ratio (p≤0.05). There were no alterations in the cortisol concentrations of groups and no significant correlation was found between IgA and cortisol (p≤0.05). Conclusion: Findings indicated that resistance training caused increase in salivary IgA as one of the immune indexes and increase in DHEA and the DHEA: cortisol ratio as one of the body anabolic status indexes. Endurance training however, performed after resistance training suppressed some of the positive adaptation of resistance training per se.
