Roles of Physical Activity for the Prevention of Non-Communicable Diseases: Practice Questions

• a.Improving insulin sensitivity and enhancing glucose uptake by skeletal muscles
• b.Eliminating the need for the pancreas to secrete any glucagon during rest
• c.Decreasing the total number of red blood cells to reduce blood viscosity
• d.Increasing the production of bile in the liver to digest complex carbohydrates

• a.

  By increasing the secretion of glucagon from the pancreas to lower blood sugar

• b.

  By decreasing the body's overall sensitivity to insulin

• c.

  By reducing the total number of insulin receptors on the surface of target cells

• d.

  By increasing the translocation of glucose transporter proteins (GLUT4) to the cell membrane in skeletal muscles

• a.Increasing the concentration of secondary bile acids in the colon
• b.Reducing the activity of antioxidant enzymes in the intestinal lining
• c.Promoting the proliferation of epithelial cells through localized inflammation
• d.Shortening the transit time of waste through the large intestine

• a.By decreasing blood plasma volume to very low levels to reduce pressure
• b.By improving endothelial function and reducing systemic vascular resistance
• c.By increasing resting heart rate and sympathetic nervous system activity
• d.By increasing blood viscosity and total peripheral resistance

• a.It allows the body to store more energy as visceral fat for later use.
• b.It eliminates the thermic effect of food (TEF) during the post-exercise recovery period.
• c.It significantly lowers the Basal Metabolic Rate (BMR) to preserve glycogen.
• d.It helps preserve or increase fat-free mass, which helps maintain a higher resting metabolic rate.
