Diabetes Education Certification Physical Activity & Exercise 2

Question 1

A patient with type 2 diabetes asks how soon after starting an exercise program they can expect to see improvements in insulin sensitivity. What is the most accurate response?

Accepted Answer

A single bout of exercise can improve insulin sensitivity for up to 24–48 hours

Answer

Even a single session of moderate-intensity exercise can enhance insulin sensitivity for 24–48 hours, independent of weight loss.

Question 2

Which mechanism primarily explains why resistance training improves glucose control in people with type 2 diabetes?

Accepted Answer

Increased muscle mass leading to greater glucose disposal capacity

Answer

Resistance training builds skeletal muscle mass, which is the primary site of insulin-mediated glucose uptake, increasing overall glucose disposal.

Question 3

A patient with type 1 diabetes is planning a 45-minute afternoon swim. Her pre-exercise blood glucose is 140 mg/dL. What is the most appropriate guidance?

Accepted Answer

Proceed with exercise; the blood glucose level is acceptable

Answer

A pre-exercise blood glucose of 140 mg/dL is within the safe range (100–250 mg/dL) for most patients with type 1 diabetes to begin aerobic exercise.

Question 4

What is the primary concern with high-intensity anaerobic exercise (e.g., sprinting) in a patient with type 1 diabetes?

Accepted Answer

It triggers a catecholamine surge that can raise blood glucose acutely

Answer

Anaerobic exercise triggers catecholamine release, which stimulates hepatic glucose production and can cause transient hyperglycemia.

Question 5

For a sedentary adult with type 2 diabetes and no contraindications, which exercise prescription aligns with ADA guidelines?

Accepted Answer

150 minutes per week of moderate-intensity aerobic activity with no more than 2 consecutive rest days

Answer

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