CSC Recovery and Regeneration

Question 1

Which sleep stage is most critical for physical recovery and muscle repair in athletes?

Accepted Answer

Slow-wave sleep (Stage 3 NREM)

Answer

Stage 1 NREM (light sleep)

Answer

Stage 2 NREM

Answer

REM sleep

Question 2

What is the primary physiological purpose of active recovery (low-intensity exercise post-training) compared to passive rest?

Accepted Answer

Accelerates lactate removal and maintains blood flow to promote clearance of metabolic byproducts

Answer

Burns more calories during recovery

Answer

Builds additional muscle protein synthesis

Answer

Reduces core body temperature faster

Question 3

Cold water immersion (CWI) post-training reduces perceived soreness but may have which long-term drawback for strength athletes?

Accepted Answer

Blunts the inflammatory signaling needed for training adaptations (hypertrophy and strength gains)

Answer

Increases risk of overtraining

Answer

Causes dehydration

Answer

Reduces flexibility permanently

Question 4

What heart rate variability (HRV) trend over several consecutive mornings would most strongly indicate insufficient recovery in an athlete?

Accepted Answer

Progressively declining HRV trend with subjective fatigue

Answer

Stable HRV with occasional small fluctuations

Answer

Gradually increasing HRV over days

Answer

HRV that varies between morning and evening

Question 5

Which of the following is an evidence-based recovery modality for reducing neuromuscular fatigue between training sessions?

Accepted Answer

Foam rolling and soft tissue work

Answer

Extended static stretching (60+ minutes)

Answer

Passive lying for 12+ hours

Answer

High-intensity interval training on rest days

Question 6

Sleep deprivation in athletes has been most consistently associated with which performance outcome?

Accepted Answer

Impaired reaction time, decision making, and reduced maximal strength output

Answer

Decreased aerobic VO2max only

Answer

Improved anaerobic power due to sympathetic arousal

Answer

No significant effect on performance
