NAFC Special Populations and Health Conditions 1 — Questions and Answers
Question 1: Which type of exercise is most beneficial for improving bone density in older adults?
- Swimming
- Cycling
- Weight-bearing and resistance training (Correct answer)
- Stretching only
Correct answer: Weight-bearing and resistance training
Weight-bearing and resistance training apply mechanical stress to bones, stimulating osteoblast activity and increasing bone mineral density, which helps prevent osteoporosis.
Question 2: What is the primary exercise consideration for clients with Type 2 diabetes?
- Avoid all cardiovascular exercise
- Monitor blood glucose before, during, and after exercise to prevent hypoglycemia (Correct answer)
- Exercise only in the fasted state
- Focus exclusively on high-intensity interval training
Correct answer: Monitor blood glucose before, during, and after exercise to prevent hypoglycemia
Clients with Type 2 diabetes should monitor blood glucose around exercise because physical activity lowers blood sugar and can cause hypoglycemia, especially when taking insulin or secretagogues.
Question 3: During pregnancy, which exercise position should generally be avoided after the first trimester?
- Standing exercises
- Seated resistance training
- Supine (lying on back) exercises (Correct answer)
- Side-lying stretches
Correct answer: Supine (lying on back) exercises
After the first trimester, supine exercises should be avoided because the growing uterus can compress the inferior vena cava, reducing venous return and potentially causing dizziness or hypotension.
Question 4: What does 'sarcopenia' refer to?
- Excess fat storage in the abdominal region
- Age-related loss of muscle mass and strength (Correct answer)
- Inflammation of tendon insertion points
- Bone density loss due to aging
Correct answer: Age-related loss of muscle mass and strength
Sarcopenia is the progressive, age-related loss of skeletal muscle mass, strength, and function, which increases fall risk and reduces functional independence in older adults.
Question 5: Which exercise recommendation is appropriate for clients with controlled hypertension?
- Avoid all forms of exercise
- Emphasize moderate-intensity aerobic exercise and avoid heavy Valsalva maneuver (Correct answer)
- Focus only on maximum strength training
- Exercise only in high-altitude environments
Correct answer: Emphasize moderate-intensity aerobic exercise and avoid heavy Valsalva maneuver
Moderate-intensity aerobic exercise is beneficial for hypertensive clients and can lower blood pressure; the Valsalva maneuver should be avoided as it sharply spikes blood pressure.
Question 6: What is the Borg Rating of Perceived Exertion (RPE) scale range?
- 0–5
- 1–10
- 6–20 (Correct answer)
- 10–100
Correct answer: 6–20
The original Borg RPE scale ranges from 6 to 20, designed so that multiplying the number by 10 approximates heart rate; a modified 0–10 scale also exists.
