Figure 1. Relative changes in metabolites in response to exercise.

Figure 1

Heatmaps show changes in metabolites compared to baseline at the peak exercise time point (left panel) and at 60 minutes after exercise (right). Shades of red and green represent fold-increase and fold-decrease of a metabolite, respectively, relative to baseline metabolite concentrations (see color scale). Three distinct plasma samples are represented: peripheral plasma from the ETT cohort; pulmonary arterial (PA) plasma from subjects undergoing CPET; and superior vena cava (SVC) plasma from subjects undergoing CPET.
