CPSS Acute and Chronic Monitoring 2

Question 1

Which heart rate variability (HRV) metric is most commonly used to reflect parasympathetic nervous system activity in athlete monitoring?

Accepted Answer

rMSSD

Answer

rMSSD (root mean square of successive differences) reflects parasympathetic (vagal) activity and is the most widely used HRV metric in daily athlete monitoring.

Question 2

An athlete's acute:chronic workload ratio (ACWR) rises to 1.8 after a training spike. What does this indicate?

Accepted Answer

The athlete is at elevated injury risk due to excessive acute load

Answer

An ACWR above 1.5 is associated with significantly elevated injury risk, as it indicates the acute load greatly exceeds the chronic fitness base.

Question 3

Which biomarker is most sensitive for detecting early-stage muscle damage following eccentric exercise?

Accepted Answer

Creatine kinase (CK)

Answer

Creatine kinase (CK) leaks from damaged muscle cells and is the most sensitive and specific early-stage marker of skeletal muscle damage.

Question 4

In the context of session RPE (sRPE), how is training load calculated?

Accepted Answer

RPE × training duration in minutes

Answer

Session RPE training load is calculated by multiplying the RPE score (0–10 Borg CR10 scale) by the total session duration in minutes.

Question 5

Which of the following best describes the 'fitness-fatigue' model in athlete monitoring?

Accepted Answer

Performance = fitness − fatigue, where both decay at different rates

Answer

The fitness-fatigue model states that performance equals the net difference between fitness (slow to develop, slow to decay) and fatigue (fast to accumulate, fast to decay).
