CSCS Special Populations & Injury Prevention 2 — Questions and Answers
Question 1: Which resistance training adaptation is most impaired in older adults (65+) compared to younger adults?
- Endurance capacity
- Type II muscle fiber hypertrophy (Correct answer)
- Cardiovascular efficiency
- Flexibility gains
Correct answer: Type II muscle fiber hypertrophy
Older adults show blunted Type II (fast-twitch) fiber hypertrophy due to anabolic hormone decline and satellite cell dysfunction.
Question 2: A pregnant athlete in her second trimester asks about supine exercise. The CSCS should recommend avoiding it primarily because of:
- Increased risk of muscle cramps
- Aortocaval compression reducing cardiac output (Correct answer)
- Elevated core temperature risk
- Reduced balance and stability
Correct answer: Aortocaval compression reducing cardiac output
The supine position allows the uterus to compress the inferior vena cava and aorta, reducing maternal cardiac output and fetal blood flow.
Question 3: For an athlete with type 1 diabetes, which scenario poses the greatest risk of exercise-induced hypoglycemia?
- High-intensity interval training lasting 10 minutes
- Prolonged moderate-intensity aerobic exercise lasting 60 minutes (Correct answer)
- Heavy resistance training with 3-minute rest periods
- Plyometric training with 5-minute rest intervals
Correct answer: Prolonged moderate-intensity aerobic exercise lasting 60 minutes
Prolonged moderate aerobic exercise substantially depletes muscle glycogen and increases insulin sensitivity, creating the highest hypoglycemia risk.
Question 4: When designing a program for a youth athlete (age 12), relative to an adult, the CSCS should primarily adjust:
- Eliminate all resistance training until puberty
- Emphasize technique, lower loads, and higher repetitions (Correct answer)
- Use exclusively machine-based exercises for safety
- Focus only on cardiovascular conditioning
Correct answer: Emphasize technique, lower loads, and higher repetitions
Youth programs should prioritize movement skill development with lighter loads and higher reps, as neuromuscular learning is the primary training goal.
Question 5: An athlete with hypertension is cleared for exercise. Which exercise modality carries the greatest acute blood pressure risk?
- Submaximal aerobic cycling
- Heavy Valsalva-assisted resistance training (Correct answer)
- Swimming at moderate intensity
- Walking on a treadmill at 3 mph
Correct answer: Heavy Valsalva-assisted resistance training
The Valsalva maneuver during heavy lifting causes dramatic acute blood pressure spikes that are particularly dangerous in hypertensive individuals.
Question 6: Patellofemoral pain syndrome is most commonly worsened by which movement pattern deficiency?
- Excessive ankle dorsiflexion
- Contralateral hip drop due to hip abductor weakness (Correct answer)
- Reduced lumbar lordosis
- Excessive ankle supination
Correct answer: Contralateral hip drop due to hip abductor weakness
Hip abductor weakness allows the femur to adduct and internally rotate, increasing lateral patellar compression and patellofemoral contact stress.
Question 7: For an obese client (BMI 38), which initial exercise selection is most appropriate to minimize joint stress while building aerobic base?
- High-impact step aerobics
- Water-based exercise or swimming (Correct answer)
- Long-distance jogging
- Jump rope training
Correct answer: Water-based exercise or swimming
Aquatic exercise provides buoyancy that reduces weight-bearing joint stress by up to 90%, making it ideal for obese individuals starting an exercise program.
