CPSS Key Performance Indicator Identification 3

Question 1

A sport scientist is designing KPIs for a powerlifting program. Which metric best captures strength development over a mesocycle?

Accepted Answer

Relative strength ratio (1RM ÷ body mass)

Answer

Relative strength ratio normalizes strength to body mass, allowing meaningful comparisons across athletes and over time regardless of weight class changes.

Question 2

Which KPI would a sport scientist prioritize to assess the acute-chronic workload ratio (ACWR) for injury risk management?

Accepted Answer

Rolling 7-day vs. 28-day training load

Answer

ACWR compares the acute (7-day) training load to the chronic (28-day) load, identifying spikes that elevate injury risk.

Question 3

In swimming, which KPI most directly reflects stroke efficiency as an indicator of technical performance?

Accepted Answer

Stroke index (velocity × stroke length)

Answer

Stroke index combines velocity and stroke length to quantify propulsive efficiency, making it a sensitive technical KPI for swimmers.

Question 4

A performance analyst notices a KPI is trending favorably but the athlete's competition results are declining. This likely indicates:

Accepted Answer

The KPI is not predictive of competition outcome

Answer

When a KPI improves but performance outcomes decline, the KPI lacks predictive validity for competition, signaling a need for KPI re-evaluation.

Question 5

For monitoring hydration status as a performance KPI in endurance athletes, which field measure is most practical?

Accepted Answer

Urine specific gravity

Answer

Urine specific gravity can be assessed cheaply and rapidly in the field, providing a practical hydration KPI without laboratory equipment.
