The run has just begun; the displayed values are still close to the resting reference state.
Explore the mechanism The demand rises
From the first strides the leg muscles need far more energy each second than they did at rest, and the systems that supply them begin to scale up.
Evidence for this step
Muscle contraction typically increases glucose uptake into working muscle by moving GLUT4 transporters to the cell surface, by a route separate from the one insulin acts through, and circulating insulin usually falls during aerobic exercise. moderate · View sources
