The analysis and changes in amino acid levels induced by the ultramarathon run are presented in Analysis of the two-factor mixed ANOVA model also revealed an effect of UM and UM × GR interactions on the amino acid metabolites (The dimethylamine (DMA) and symmetric dimethylarginine (SDM) ratio increased relative to the baseline values in the supplemented group, with no changes in the control group. On the other hand, no major changes in the Trp/BCAA ratio were apparent in the supplemented group, with a notable increase immediately after the run compared to the baseline values in the control group.
