Estimated muscle extracellular (Rextracell), transport (Rtransport), and phoshorylation (Rphos) resistances to muscle glucose uptake (MGU) during insulin clamps, exercise, and during insulin clamps in rats fed a high-fat (HF) diet. Glucose gradients were calculated using the countertransport method, and the index of MGU (Rg) was calculating using 2-deoxy-[3H]glucose (2[3H]DG; Ref. 65). Values are expressed as %total resistance to MGU. Ga, arterial glucose; Ge, extracellular glucose; Gi, intracellular glucose.
