Analysis of the saliva innate immune proteins and microbiota prior and post exercise. a Boxplot of abundance ratios of innate immune proteins comparing pre- and post-exercise sections. Stars represent outliers. b ELISA analysis of saliva dermcidin levels prior and after the exercise sessions. ^**P ≤ 0.01 (Student’s t-test). c Number of diacylglycerophosphoethanolamine and diacylglycerophosphoglycerol species containing C15 fatty acids in different body fluids. ^**P ≤ 0.01 (Fisher’s exact test). d Fraction of human and bacterial proteins in the saliva proteomics. e Boxplot of abundance ratios of total iBAQ scores from proteins of different organisms comparing pre- and post-exercise sessions. Stars represent outliers. Down significantly down-regulated molecule, PE diacylglycerophosphoethanolamine, PG diacylglycerophosphoglycerol, Up significantly up-regulated molecule, ns non-significant
