Abstract

Several studies have demonstrated that oral glucose tolerance is impaired in the immediate postexercise period. A double-tracer technique was used to examine glucose kinetics during a 2-h oral glucose (75 g) tolerance test (OGTT) 30 min after exercise (Ex, 55 min at 71 ± 2% of peak O 2 uptake) and 24 h after exercise (Rest) in endurance-trained men. The area under the plasma glucose curve was 71% greater in Ex than in Rest ( P = 0.01). The higher glucose response occurred even though whole body rate of glucose disappearance was 24% higher after exercise ( P = 0.04, main effect). Whole body rate of glucose appearance was 25% higher after exercise ( P = 0.03, main effect). There were no differences in total (2 h) endogenous glucose appearance (R a e) or the magnitude of suppression of R a e, although R a e was higher from 15 to 30 min during the OGTT in Ex. However, the cumulative appearance of oral glucose was 30% higher in Ex ( P = 0.03, main effect). There were no differences in glucose clearance rate or plasma insulin responses between the two conditions. These results suggest that adaptations in splanchnic tissues by prior exercise facilitate greater glucose output from the splanchnic region after glucose ingestion, resulting in a greater glycemic response and, consequently, a greater rate of whole body glucose uptake.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Greater gut glucose release and greater hepatic glucose output occur in response to meals immediately post exercise, favouring an increase in muscle glucose uptake and glycogen storage.

    “Other studies have confirmed greater gut glucose release and greater hepatic glucose output in response to meals immediately post exercise, favouring an increase in muscle glucose uptake and glycogen storage (91).”

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.
