Diabetes Exercise and Activity 4

Question 1

During a group fitness class, a person with Type 1 diabetes begins to feel shaky and confused. Their glucometer reads 58 mg/dL. What is the immediate first step?

Accepted Answer

Stop exercise and consume 15g of fast-acting carbohydrates immediately

Answer

The '15-15 rule' for mild-to-moderate hypoglycemia calls for stopping activity and consuming 15g of fast-acting carbohydrates, then rechecking glucose in 15 minutes.

Question 2

Which statement about exercise and HbA1c is most accurate?

Accepted Answer

Regular exercise can lower HbA1c by approximately 0.5-1.0% in Type 2 diabetes

Answer

Meta-analyses show that regular structured exercise reduces HbA1c by approximately 0.5-1.0% in Type 2 diabetes through improved insulin sensitivity and increased glucose utilization.

Question 3

A diabetic patient is planning to start high-intensity interval training (HIIT). What should they be aware of regarding blood glucose response?

Accepted Answer

HIIT can initially raise blood glucose due to catecholamine release before it drops

Answer

The intense anaerobic bursts in HIIT trigger adrenaline and cortisol release, which can spike blood glucose during the session, followed by a drop during recovery.

Question 4

What is the recommended blood glucose target range before starting moderate aerobic exercise for a person with Type 1 diabetes?

Accepted Answer

90-250 mg/dL

Answer

A pre-exercise blood glucose of 90-250 mg/dL is generally considered safe to begin moderate aerobic exercise for most people with Type 1 diabetes.

Question 5

How does prolonged sitting (sedentary behavior) affect blood glucose control, even in people who meet weekly exercise guidelines?

Accepted Answer

Prolonged sitting independently worsens insulin resistance and glucose levels

Answer

Research shows prolonged uninterrupted sitting independently raises post-meal glucose and insulin resistance, even in people who exercise regularly — breaking sitting time every 30 minutes helps.
