 Physical activity and sedentary lifestyle is known to be associated with insulin resistance IR. The association between sedentary lifestyle and IR measured in the fasting state is partly explained by adipositas, whereas the associations between IR and insulin secretion based on Oral Glucose Tolerance Test is independent of adipositas 22. Studies also show higher insulin sensitivity if patients are physical active just before a meal 23 and increased fitness associates to increased level of glucose transporters GLUT4 and thereby the exploit of insulin 24.
