Lipid networks, illustrating acute exercise effects (0–10 min) on plasma metabolites in adult women, regardless of fitness and weight loss intervention. The biochemical network displays precursor–product relationships for fatty acids, oxylipins (OxL) and endocannabinoids (eCB) for related subclasses of fatty acid precursors including saturated and monounsaturated, omega‐6 and omega‐3 polyunsaturated fatty acids. The magnitude, direction and significance of changes are denoted by node size (the magnitude of the spearman correlation over the 10 min), border or fill colors (red, increased plasma concentration; blue, reduced plasma concentration), respectively. Significant changes are shown for lipids with p _FDR values ≤.05 from mixed effects models. Non‐measured or undetected species are displayed in gray symbols with no borders
