Abstract

The metabolic response to exercise in obese postabsorptive noninsulin-dependent diabetics was compared to that of obese nondiabetics. Exercise consisted of 45 min on a cycle ergometer at 60% maximum oxygen consumption. Six diabetic subjects were studied during oral hypoglycemic therapy and four on diet alone. The sulfonylurea therapy had no effect on the response. Glycemia was elevated at rest in both diabetic subgroups (192 +/- 24 mg/dl for diet alone, 226 +/- 36 mg/dl for sulfonylurea treatment) and a similar fall (35 and 37 mg/dl, respectively) occurred with exercise. In control subjects, glycemia was 86 +/- 4 mg/dl and did not change with exercise. In the diabetics at rest, glucose production was elevated (220 +/- 25 mg/min), whereas the metabolic clearance of glucose was suppressed. During exercise the increase in glucose utilization was similar to that in controls, but glucose production failed to increase significantly, thus accounting for the decline in plasma glucose. At rest, plasma immunoreactive insulin (IRI) was elevated to 0.90 ng/ml in the controls and decreased to 0.65 ng/ml with exercise. In the diabetics IRI was similarly elevated (0.89 ng/ml) but failed to decrease normally with exercise. Lactate, pyruvate, alanine, and free fatty acids increased similarly in diabetics and controls, whereas the increase in 3-hydroxybutyrate during recovery was less in diabetics. The sustained insulinemia, the basal overproduction of glucose, and hyperglycemia itself may all…

  • In the postabsorptive state, moderate-intensity exercise decreases plasma glucose concentrations and is followed by an increase in insulin sensitivity in NIDDM patients.

    “In the postabsorptive state exercise of moderate intensity has been shown to decrease plasma glucose concentrations and is followed by an increase in insulin sensitivity [1-5].”

    From The effect of moderate exercise on postprandial glucose homeostasis in NIDDM patients (1997) · cites this paper as [1]

  • Often an increase in hepatic glucose production is not seen with exercise when insulin levels are elevated.

    “The finding of no change in glucose production in response to exercise in the postprandial state is in line with the facts that often an increase in hepatic glucose production is not seen with exercise when insulin levels are elevated [1, 7, 22, 23] and that exercise does not change glucose absorption from the gut [24].”

    From The effect of moderate exercise on postprandial glucose homeostasis in NIDDM patients (1997) · cites this paper as [1]

  • In individuals with type 2 diabetes performing moderate exercise, blood glucose utilization by muscles usually rises more than hepatic glucose production, and blood glucose levels tend to decline.

    “In individuals with type 2 diabetes performing moderate exercise, BG utilization by muscles usually rises more than hepatic glucose production, and BG levels tend to decline ( 191 ).”

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.
