Abstract
The capillary permeability in human skeletal muscle, expressed as capillary diffusion capacity (CDC) for 51Cr-EDTA, was determined during exercise with a local clearance method in two groups of healthy male subjects: a younger group with a mean age of 30 years and an older one with a mean age of 58 years. The main finding was that, in both age groups, CDC was significantly negatively correlated to the early phase of insulin response to an intravenous glucose load. No correlation was found between CDC and peripheral insulin sensitivity. CDC was significantly higher in the older age group (P less than 0.01) independent of insulin response, blood flow and body weight. These data indicate that subjects with low insulin response to glucose have a higher capillary permeability than high responders, and that muscle capillary permeability increases with age.
