Exercise Prescription Flashcards

A patient with type 2 diabetes wants to start resistance training. What is the recommended minimum frequency per week?

Answer: 2-3 times per week

Resistance training is recommended 2-3 non-consecutive days per week for people with diabetes.

Which of the following best describes the Borg Rating of Perceived Exertion (RPE) scale range for moderate-intensity exercise?

Answer: 12-14

Moderate-intensity exercise corresponds to an RPE of 12-14 on the 6-20 Borg scale.

A person with diabetes is exercising in cold weather. What is the primary concern regarding insulin absorption?

Answer: Cold decreases insulin absorption at injection sites

Cold temperatures cause vasoconstriction, which slows insulin absorption from subcutaneous injection sites.

What is the recommended duration of moderate-intensity aerobic exercise per week for adults with diabetes according to ADA guidelines?

Answer: 150 minutes

The ADA recommends at least 150 minutes of moderate-intensity aerobic activity per week for adults with diabetes.

A patient with proliferative diabetic retinopathy should avoid which type of exercise?

Answer: High-intensity weightlifting with Valsalva maneuver

Heavy resistance exercise with breath-holding (Valsalva) sharply increases intraocular and blood pressure, risking vitreous hemorrhage in proliferative retinopathy.

What blood glucose level is generally recommended as the upper threshold above which a person with type 1 diabetes should postpone vigorous exercise?

Answer: 300 mg/dL

Exercise is generally not recommended when blood glucose exceeds 300 mg/dL, especially with ketones present, as vigorous activity can worsen hyperglycemia.

Which exercise type primarily improves insulin sensitivity by increasing GLUT-4 transporter translocation to muscle cell membranes?

Answer: Aerobic and resistance exercise

Both aerobic and resistance exercise promote GLUT-4 translocation to the cell surface, enhancing glucose uptake independent of insulin.
