Exercise Metabolism and the Molecular Regulation of Skeletal Muscle Adaptation

Open access

Abstract

Preservation of aerobic fitness and skeletal muscle strength through exercise training can ameliorate metabolic dysfunction and prevent chronic disease. These benefits are mediated in part by extensive metabolic and molecular remodeling of skeletal muscle by exercise. Aerobic and resistance exercise represent extremes on the exercise continuum and elicit markedly different training responses that are mediated by a complex interplay between a myriad of signaling pathways coupled to downstream regulators of transcription and translation. Here, we review the metabolic responses and molecular mechanisms that underpin the adaptatation of skeletal muscle to acute exercise and exercise training.

Claims other papers make about this one

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

  • This shift is principally achieved by an augmentation in mitochondrial volume, FA transport and enzymatic adaptations to use fat, and a reduction of cell signals such as ADP and AMP during exercise at submaximal work rates thus reducing the activation of key enzymes of carbohydrate metabolism.

    “This is principally achieved by an augmentation in mitochondrial volume, FA transport and enzymatic adaptations (e.g., increase hydroacyl-CoA-dehydrogenase) to use fat, and a reduction of cell signals such as ADP and AMP during exercise at submaximal work rates thus reducing the activation of key enzymes (e.g., glycogen phosphorylase and pyruvate dehydrogenase) of carbohydrate metabolism [92,160].”
  • Exercise promotes glucose uptake and glycogen synthesis and increases insulin sensitivity, and this persists long after the cessation of exercise.

    “Exercise promotes glucose uptake and glycogen synthesis and increases insulin sensitivity, and this persists long after the cessation of exercise (1, 2).”
  • PGC1α after exercise can promote mitochondrial biogenesis by driving the expression of nuclear- and mitochondrial-encoded genes.

    “The induction of PGC1α (peroxisome proliferator–activated receptor gamma coactivator 1α) after exercise can promote mitochondrial biogenesis by driving the expression of nuclear- and mitochondrial-encoded genes.”
  • The enhanced skeletal muscle insulin sensitivity after exercise affords metabolic flexibility and a means for replenishing glycogen to deal with subsequent bouts of intense physical activity.

    “The enhanced skeletal muscle insulin sensitivity after exercise affords metabolic flexibility and a means for replenishing glycogen to deal with subsequent bouts of intense physical activity (1, 2).”
  • Exercise results in skeletal muscle exposure to acute stresses that stimulate compensatory and adaptive physiological responses.

    “Exercise results in skeletal muscle exposure to acute stresses that stimulate compensatory and adaptive physiological responses (1, 2).”

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.
