CPSS Athlete Recovery Strategies 2 — Questions and Answers
Question 1: Which biomarker is most commonly used to assess muscle damage and the need for extended recovery in athletes?
- Creatine kinase (CK) (Correct answer)
- C-reactive protein (CRP)
- Interleukin-6 (IL-6)
- Cortisol
Correct answer: Creatine kinase (CK)
Creatine kinase is the primary marker of skeletal muscle damage and is widely used to gauge recovery status after intense exercise.
Question 2: A sport scientist wants to monitor an athlete's autonomic nervous system recovery daily. Which non-invasive tool is most appropriate?
- Heart rate variability (HRV) monitoring (Correct answer)
- Blood lactate testing
- VO2max assessment
- Grip strength dynamometry
Correct answer: Heart rate variability (HRV) monitoring
HRV reflects the balance between sympathetic and parasympathetic activity and is a validated, non-invasive daily recovery metric.
Question 3: Which sleep stage is considered most critical for physical recovery and anabolic hormone release in athletes?
- Stage 1 NREM
- Stage 2 NREM
- Slow-wave sleep (SWS/Stage 3) (Correct answer)
- REM sleep
Correct answer: Slow-wave sleep (SWS/Stage 3)
Slow-wave sleep drives the majority of growth hormone secretion, tissue repair, and immune restoration in athletes.
Question 4: An athlete reports persistent muscle soreness 72 hours after eccentric exercise. Which recovery modality has the strongest evidence for reducing DOMS at this timepoint?
- Massage therapy (Correct answer)
- Static stretching
- Passive rest only
- Heat application
Correct answer: Massage therapy
Massage therapy has the most consistent evidence for reducing perceived DOMS and improving short-term recovery from eccentric exercise.
Question 5: What is the primary physiological rationale for using compression garments post-exercise?
- Increasing metabolic rate
- Reducing interstitial fluid accumulation and edema (Correct answer)
- Elevating muscle temperature
- Accelerating glycogen resynthesis
Correct answer: Reducing interstitial fluid accumulation and edema
Compression garments apply graduated external pressure that reduces edema, improves venous return, and limits exercise-induced swelling.
Question 6: A team schedules back-to-back competition days. Which dietary strategy is the highest priority for between-game recovery?
- High-fat meal to spare glycogen
- Rapid carbohydrate intake (1.0–1.2 g/kg/hr) in the first 4 hours (Correct answer)
- Protein-only meal within 30 minutes
- Fasting to reduce inflammation
Correct answer: Rapid carbohydrate intake (1.0–1.2 g/kg/hr) in the first 4 hours
Aggressive carbohydrate loading at 1.0–1.2 g/kg/hr in the early post-exercise window maximizes glycogen resynthesis rates for rapid recovery.
Question 7: Which psychological recovery strategy is best supported by evidence for reducing perceived fatigue and improving readiness in elite athletes?
- Passive distraction (e.g., watching TV)
- Mindfulness-based stress reduction (MBSR) (Correct answer)
- Competitive video gaming
- Social isolation
Correct answer: Mindfulness-based stress reduction (MBSR)
Mindfulness-based interventions consistently reduce stress perception, improve sleep quality, and enhance subjective recovery scores in athletes.
