Quantification of nutrient fluxes during acute exercise

Although metabolic benefits of exercise are well known, an integrated metabolic understanding of exercise is not well understood.

The researchers used 13C-isotope infusions to quantify metabolic fluxes in fasted and fed exercising mice.

Exercise causes dynamic changes in systemic nutrient fluxes and interconversions and in fuel preferences across a wide range of organs, which are fine-tuned to adapt to changes in feeding status and workload.
