CPSS - Certified Performance and Sport Scientist Managing Training Load Questions and Answers

Question 1

A sport scientist observes that a team's weekly training load is high, but the day-to-day variability is very low. Which training metric would quantify this lack of variability, and what is the primary risk associated with it?

Accepted Answer

Training Monotony; risk of illness and overtraining

Answer

Training Monotony is a metric calculated by dividing the mean daily training load of a week by the standard deviation of the daily loads. A high score indicates that the training stimulus is very similar day after day. This lack of variation, especially when overall load is high, is associated with an increased risk of non-functional overreaching, illness, and injury due to psychobiological staleness.

Question 2

A Certified Performance and Sport Scientist notes that a swimmer's external load (total yardage) has decreased for three consecutive days. However, the athlete's resting heart rate is elevated, and their self-reported wellness scores for sleep quality and muscle soreness are poor. What is the MOST likely interpretation of this data?

Accepted Answer

The athlete is experiencing non-training related stress or is in the early stages of an illness.

Answer

This scenario highlights a divergence between external load and internal response. While the training work has decreased, the athlete's internal physiological state (elevated RHR, poor wellness) indicates significant stress. This disconnect often points to external, non-training factors such as academic pressure, personal issues, poor nutrition, or the onset of an illness, which can compromise recovery and adaptation independently of the prescribed training.

Question 3

Which of the following BEST defines 'Training Strain' as conceptualized in Foster's model of training load monitoring?

Accepted Answer

The product of an athlete's total weekly training load and their training monotony score.

Answer

Training Strain is a composite metric derived from Foster's model. It is calculated by multiplying the total training load for a given period (typically one week) by the training monotony score for that same period. It aims to provide a more comprehensive picture of the overall psychobiological stress placed on an athlete by considering both the magnitude of the load and its day-to-day variability. High strain is associated with an increased risk of negative training outcomes.

Question 4

A soccer player's acute:chronic workload ratio (ACWR) is calculated to be 1.7 after a week of intensified practice. The coaching staff has a high-volume conditioning test planned for the day's session. Based on established models of injury risk, what is the most appropriate recommendation for the sport scientist to make for this specific player?

Accepted Answer

Modify or have the player sit out the conditioning test to reduce their acute load.

Answer

An ACWR above 1.5 is widely considered to represent a 'danger zone' where the acute workload has spiked significantly relative to the chronic workload the athlete is prepared for. This places the athlete at a substantially increased risk of non-contact injury. The most prudent action is to modify the planned training to reduce the acute load, allowing the athlete's chronic base to build and the ratio to return to a safer range (ideally 0.8-1.3).

Question 5

Which of the following pairs correctly identifies an external load measure and an internal load measure, respectively?

Accepted Answer

Total distance covered (GPS) and Blood Lactate Concentration

Answer

External load refers to the objective, physical work performed by an athlete (e.g., distance covered, weight lifted). Internal load is the individual athlete's physiological and psychological response to that external load. Total distance covered, measured by GPS, is a classic external load metric. Blood lactate concentration is a direct physiological measure of the metabolic stress experienced by the athlete, making it an internal load measure.
