a) Classification model of the acute effect of strenuous exercise. Cross validated OPLS-DA score plot for the 93 model samples from exercise occasions one and two showing separation between pre- exercise (black circles) and post- exercise (gray circles) serum samples with a classification accuracy of 97.9% (class prediction (CV)). b) OPLS-DA covariance loading plot showing the variable (metabolite) contribution to the separation in the model scores. A selection of identified amino and fatty acids is named in the plot.
