Aerobic exercise training increases skeletal muscle GLUT4 protein levels, which enhances insulin-stimulated muscle glucose disposal.

Regular aerobic exercise increases the amount of GLUT4, a protein that helps move glucose into your muscles. This makes your body more sensitive to insulin and helps manage blood sugar levels more effectively.

GoodSupportsHIGH confidence
Aerobic exercise training has been shown to increase GLUT4 protein levels 20–70% in human [128–136] and rodent skeletal muscle [137–141], suggesting that aerobic training would enhance acute insulin- and exercise/muscle contraction-stimulated muscle glucose transport. Consistent with this prediction, studies have demonstrated that aerobic training enhances insulin-stimulated muscle glucose disposal 20–100% [131,134,142–146].
