CDE Exercise Prescription 5

Question 1

A patient uses a continuous glucose monitor (CGM) during exercise. At what CGM glucose trend and level should they consume 15-20g of carbohydrate prophylactically?

Accepted Answer

Glucose 90 mg/dL with a rapid downward trend arrow during aerobic exercise

Answer

A glucose of 90 mg/dL with a rapid downward CGM trend during aerobic exercise indicates imminent hypoglycemia risk warranting prophylactic carbohydrate intake.

Question 2

Which adaptation to resistance training is most responsible for long-term improvements in resting metabolism in patients with type 2 diabetes?

Accepted Answer

Increased skeletal muscle mass

Answer

Resistance training increases skeletal muscle mass, which is the primary metabolically active tissue that elevates resting metabolic rate and improves glucose disposal.

Question 3

A patient with type 1 diabetes reports hypoglycemia consistently 8-12 hours after afternoon swimming sessions. What is the most likely cause?

Accepted Answer

Delayed (late-onset) post-exercise hypoglycemia due to glycogen repletion and enhanced insulin sensitivity

Answer

Delayed hypoglycemia 6-15 hours post-exercise occurs because muscles replenish glycogen stores and insulin sensitivity remains elevated, increasing glucose uptake during this window.

Question 4

What is the Talk Test as applied to exercise intensity prescription?

Accepted Answer

Moderate intensity allows comfortable conversation but not singing; vigorous intensity limits speech to a few words

Answer

The Talk Test is a practical intensity guide: moderate exercise allows conversation but not singing, while vigorous exercise allows only brief phrases.

Question 5

For a patient with diabetic peripheral neuropathy exercising regularly, what foot care practice is most critical?

Accepted Answer

Inspect feet daily for blisters, cuts, or pressure points and wear well-fitting, moisture-wicking socks and proper footwear

Answer

Daily foot inspection and appropriate footwear prevent undetected wounds that can progress to serious infections in patients with reduced foot sensation.
