Measurement of metabolites in serum. Blood was collected with or without treadmill exercise to measure serum levels of glucose (A), TG (B), NEFA (C), glycerol (D), BHB (E) and lactate (F) in the fed or fasted state. TG, triacylglycerol; NEFA, non-esterified fatty acid; BHB, β-hydroxybutyrate. n = 6. *p < 0.05, **p < 0.01, ***p < 0.001, main effect for genotype. ###p < 0.001, main effect for fasting. †††p < 0.001, main effect for exercise. Interaction is indicated with the p-value in the figure if it was statistically significant
