CPSS Performance Assessment Technologies 5

Question 1

A sport scientist is selecting a wearable lactate analyzer for field use. Which technical specification is most critical for valid interstitial lactate monitoring during exercise?

Accepted Answer

Response lag time between blood and interstitial compartment values

Answer

Interstitial lactate lags blood lactate by several minutes, so understanding this delay is critical for accurate interpretation of real-time readings.

Question 2

In the context of performance assessment, what does 'reactive strength index modified' (RSImod) measure differently from traditional RSI?

Accepted Answer

RSImod uses countermovement jump height divided by time to takeoff instead of drop jump contact time

Answer

RSImod divides jump height by time to takeoff in a countermovement jump, making it applicable without requiring a drop jump protocol.

Question 3

Which data processing technique is used in GPS analysis to smooth positional noise and improve velocity calculation accuracy?

Accepted Answer

Kalman filtering to fuse GPS position with accelerometer data

Answer

Kalman filtering combines GPS positional data with accelerometer inputs to produce smoother, more accurate velocity estimates by minimizing measurement noise.

Question 4

When a sport scientist reports isokinetic knee extensor strength as a 'bilateral deficit,' what specific finding does this describe?

Accepted Answer

The sum of unilateral limb forces exceeds bilateral simultaneous force production

Answer

Bilateral deficit occurs when the combined output from two separate unilateral efforts exceeds the force produced when both limbs act simultaneously.

Question 5

A performance scientist needs to assess tendon stiffness non-invasively. Which technology combination provides the most valid estimate of in vivo patellar tendon stiffness?

Accepted Answer

Ultrasound imaging synchronized with dynamometer force measurements

Answer

Ultrasonography tracks tendon elongation during force application measured by a dynamometer, allowing calculation of stiffness as force divided by deformation.
