Popis: Objective: Insulin-induced capillary recruitment is considered a determinant of insulin-mediated glucose uptake. Insulin action on the microvasculature has been assessed in skin; however, there is concern as to whether the vascular responses observed in skin reflect those in the muscle. We hypothesized that insulin-induced capillary recruitment in skin would correlate with microvascular recruitment in muscle in a group of subjects displaying a wide variation in insulin sensitivity. Methods: Capillary recruitment in skin was assessed using capillary videomicroscopy, and skeletal muscle microvascular recruitment (i.e., increase in MBV) was studied using CEU in healthy volunteers (n=18, mean age: 30.6±11.1years). Both microvascular measurements were performed during saline infusion, and during a hyperinsulinemic euglycemic clamp. Results: During hyperinsulinemia, capillary recruitment in skin was augmented from 58.1±18.2% to 81.0±23.9% (p
