CDCES Exercise and Physical Activity Management 1

Question 1

What is the primary mechanism by which aerobic exercise lowers blood glucose in individuals with type 2 diabetes?

Accepted Answer

Enhanced glucose uptake by muscle cells via GLUT4 translocation independent of insulin

Answer

Aerobic exercise promotes GLUT4 translocation to muscle cell membranes, allowing glucose uptake independent of insulin, which lowers blood glucose levels.

Question 2

According to the American Diabetes Association, adults with diabetes should aim for at least how many minutes of moderate-intensity aerobic activity per week?

Accepted Answer

150 minutes

Answer

The ADA recommends at least 150 minutes of moderate-intensity aerobic activity per week, spread over at least 3 days with no more than 2 consecutive days without activity.

Question 3

A patient with type 1 diabetes wants to begin an exercise program. Which blood glucose level should prompt the CDCES to advise the patient to postpone exercise and check urine or blood ketones?

Accepted Answer

Above 240 mg/dL

Answer

In type 1 diabetes, exercise with blood glucose above 240 mg/dL warrants checking for ketones, as exercising in a ketotic state can worsen hyperglycemia and ketoacidosis.

Question 4

Exercise-induced delayed hypoglycemia (also called late-onset hypoglycemia) most commonly occurs at what time after prolonged aerobic exercise?

Accepted Answer

6–15 hours post-exercise

Answer

Late-onset hypoglycemia typically occurs 6–15 hours after prolonged aerobic exercise as muscles replenish glycogen stores, increasing glucose uptake overnight.

Question 5

What is the minimum blood glucose level generally recommended before a person with insulin-treated diabetes begins moderate exercise to reduce the risk of hypoglycemia?

Accepted Answer

100 mg/dL

Answer

A pre-exercise blood glucose of at least 100 mg/dL is generally recommended for insulin-treated patients to provide a safety buffer against exercise-induced glucose lowering.
