Exercise, muscle, and CHO metabolism
Abstract
Carbohydrates (CHO) are a key source of energy for contracting skeletal muscle during strenuous exercise and fatigue during such exercise often coincides with CHO depletion. Our current understanding of the importance of CHO for exercise metabolism has its foundations in classic studies in the early 20th century by Scandinavian physiologists and Bengt Saltin contributed significantly to that tradition. This brief review summarizes our contemporary understanding of key aspects of muscle glycogen and glucose metabolism during exercise, through the lens of seminal studies by Bengt Saltin.

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.
