Enhanced Peripheral and Splanchnic Insulin Sensitivity in NIDDM Men After Single Bout of Exercise
Abstract
We studied glucose metabolism in non-insulin-dependent diabetic (NIDDM) men with and without glycogen-depleting cycle exercise 12 h beforehand and have compared the results to our previous data in lean and obese subjects. Rates of total glucose utilization, glucose oxidation, nonoxidative glucose disposal (NOGD), glucose metabolic clearance rate (MCR), and endogenous glucose production (EGP) were determined with a "two-level" insulin-clamp technique (100-min infusions at 40 and 400 mU X m-2 X min-1) combined with indirect calorimetry and D-3-[3H]glucose infusion. Muscle biopsy specimens from vastus lateralis were analyzed for glycogen content and glycogen synthase activity before and after insulin infusions. After exercise, NIDDM subjects had muscle glycogen concentrations comparable with those of lean and obese subjects. The activation of glycogen synthase both by prior exercise and insulin infusion was similar to lean controls. After exercise, total glucose disposal was significantly increased during the 40-mU X m-2 X min-1 infusion (P less than .05), but the increase observed during the 400-mU X m-2 X min-1 infusion was not significant. These increases after exercise were the result of significantly higher NOGD during both levels of insulin infusion. The MCR of glucose during both insulin infusions was reduced in NIDDM compared with lean subjects but was very similar to that in obese nondiabetics. Basal EGP was significantly reduced on the morning after exercise (4.03 +/-…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
