CPD Physical Fitness & Wellness 4 — Questions and Answers
Question 1: Which exercise most directly trains the muscle groups used when an officer physically restrains a resisting subject?
- Long-distance running
- Seated leg press
- Core and upper body compound movements (e.g., deadlifts, rows) (Correct answer)
- Wrist curls
Correct answer: Core and upper body compound movements (e.g., deadlifts, rows)
Restraining a subject requires integrated core and upper body strength, best developed through compound movements like deadlifts and rows.
Question 2: What does VO2 max represent in fitness testing?
- Maximum oxygen the body can consume during intense exercise (Correct answer)
- The volume of air exhaled in one breath
- Blood oxygen saturation at rest
- Maximum heart rate achievable
Correct answer: Maximum oxygen the body can consume during intense exercise
VO2 max is the maximum rate at which the body can consume oxygen during exhaustive exercise, and is the gold standard measure of aerobic capacity.
Question 3: An officer with hypertension is cleared for duty. Which activity modification is most appropriate during fitness training?
- Avoid all cardiovascular exercise
- Monitor blood pressure before and after exercise and avoid maximal static holds (Correct answer)
- Limit all activity to stretching only
- Train at maximum intensity to reduce blood pressure quickly
Correct answer: Monitor blood pressure before and after exercise and avoid maximal static holds
Officers with hypertension should monitor blood pressure around exercise sessions and avoid prolonged maximal isometric holds, which spike blood pressure acutely.
Question 4: How many hours of sleep per night do health guidelines recommend for adults to maintain cognitive and physical performance?
- 4–5 hours
- 6 hours
- 7–9 hours (Correct answer)
- 10–12 hours
Correct answer: 7–9 hours
The CDC and sleep experts recommend 7–9 hours per night for adults to maintain optimal cognitive function, reaction time, and physical recovery.
Question 5: Which of the following is the best indicator that an officer has recovered adequately between intense training sessions?
- Feeling no muscle soreness at all
- Resting heart rate has returned to baseline and energy levels feel normal (Correct answer)
- Weight has not changed
- Being able to complete one more repetition than last session
Correct answer: Resting heart rate has returned to baseline and energy levels feel normal
Return of resting heart rate to baseline and normal energy levels are reliable indicators of adequate physiological recovery.
Question 6: During the sit-and-reach test included in some CPD fitness assessments, which muscle group's flexibility is primarily evaluated?
- Quadriceps and hip flexors
- Chest and shoulders
- Hamstrings and lower back (Correct answer)
- Calf muscles
Correct answer: Hamstrings and lower back
The sit-and-reach test primarily assesses hamstring and lower back flexibility, areas critical for injury prevention in active duty officers.
Question 7: Which substance, if used in excess, is known to impair an officer's reaction time and decision-making even the day after consumption?
- Caffeine
- Alcohol (Correct answer)
- Creatine
- Vitamin C supplements
Correct answer: Alcohol
Alcohol impairs cognitive function and reaction time, and residual effects can persist into the next day even after blood alcohol drops to zero.
