Abstract

Primary aging is the progressive and inevitable process of bodily deterioration during adulthood. In skeletal muscle, primary aging causes defective mitochondrial energetics and reduced muscle mass. Secondary aging refers to additional deleterious structural and functional age-related changes caused by diseases and lifestyle factors. Secondary aging can exacerbate deficits in mitochondrial function and muscle mass, concomitant with the development of skeletal muscle insulin resistance. Exercise opposes deleterious effects of secondary aging by preventing the decline in mitochondrial respiration, mitigating aging-related loss of muscle mass and enhancing insulin sensitivity. This review focuses on mechanisms by which exercise promotes "healthy aging" by inducing modifications in skeletal muscle.

  • These adaptive responses increase tolerance and protect against subsequent stressors and are considered important for the health-promoting effects of exercise.

    “These adaptive responses increase tolerance and protect against subsequent stressors and are considered important for the health-promoting effects of exercise (1, 2).”
  • 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.

  • 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).”
  • 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).”
  • Exercise promotes contraction-induced and insulin-independent glucose uptake into muscle and increases muscle insulin sensitivity that persists long after cessation of exercise.

    “Exercise not only promotes contraction-induced and insulin-independent glucose uptake into muscle, but also increases muscle insulin sensitivity that persists long after the cessation of exercise (1).”

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.
