Correlation Analysis of Differential Microorganisms and Metabolites with Pre-Competition Anxiety Indicators (n = 6). (A) The relationship between differential microorganisms and anxiety indicators was identified through RDA/CCA. The blue dotted line represents differential microorganisms, and the black solid line represents anxiety indices. The terms ‘cogni’, ‘somatic’, ‘state’, ‘individ’, ‘confi’, ‘social’, ‘soma’, ‘sportcom’ and ‘sportcog’ refer to anxiety related to the cognitive state, somatic state, state self-confidence, individual failure, self-confidence, social expectation, soma and sport traits, respectively. A long black arrow is indicative of the great effect of each anxiety index on differential microorganisms. A small angle between two arrows indicates a high correlation between anxiety indices and differential microorganisms. A sample close to the black arrow is indicative of the strong effect of an anxiety indicator on a sample. Samples in the same direction as the arrow indicate that an anxiety index is positively correlated with differential microoranisms and vice versa. Heat map of the correlation of differential metabolites in faecal (B1) and urine (B2) with anxiety levels. The differential metabolite is the ordinate and the anxiety index is the abscissa. Positive correlations are indicated by red/brown and negative correlations are indicated by blue/lake blue. *P < 0.05; **P < 0.01
