Introduction: The aims of this study were to: a) investigate salivary
immunoglobulin A (s-IgA) and cortisol (s-Cort) responses to nine competitive
fixtures in starting and non- starting soccer players; and b) compare s-IgA and s Cort responses of starters and non-starters considering match outcome.
Methods: Saliva from 19 male outfield players from an elite soccer team (mean ±
SD, age 26 ± 4 years; weight 80.5 ± 8.1 kg; height 1.83 ± 0.07 m; body-fat 10.8% ±
0.7%) was collected. Saliva samples were taken on the day before each match
(MD-1), 60-min before kick-off (MDpre), 30-min post-match (MDpost), and 72-h
post-match (MD+3). There were five wins, one draw and three losses.
Results: The mean s-IgA value was found to be significantly lower at MD+3
compared to MDpre and MDpost. s-Cort was significantly higher at MDpost
compared to MD-1 and MDpre. When compared to MDpre, a statistically
significant decrease in s-Cort was observed at MD+3 compared to MDpost.
Starters displayed higher s-Cort values across the nine matches. There was a
significant group-by-time interaction for s-Cort. There was a significant increase
in s-Cort levels at MDpost compared to MD-1 and from MDpre to MDpost in
starting players. At MDpost, starters had significantly higher s-Cort values. s-IgA
values of starting and non- starting players following successful and unsuccessful
matches did not reveal a significant difference. However, similar analysis of s-Cort
in successful matches showed a significant difference between starters and non starters. s-IgA values at MD-1, MDpre, MDpost and MD+3 in starters and non starters following successful and unsuccessful matches revealed significant
differences at MDpre and MDpost in starters, respectively. Furthermore, s-Cort
values at MD-1, MDpre, MDpost and MD+3 in starters and non-starters in
successful and unsuccessful matches revealed significant differences at MD+3
in starting players.Discussion: The present study suggests that in elite level soccer players, both
starting status and match outcome influence s-IgA and s-Cort responses,
particularly starters. Specifically, s-IgA was lower for starters before and after
the match following successful outcomes. Moreover, higher s-Cort values were
found before the match while lower values occurred after the match for starters in
successful matches.
