Question 1

Which inertial measurement unit (IMU) sensor axis combination is most commonly used to quantify athlete jump height via double integration of acceleration?

Accepted Answer

Accelerometer vertical axis alone

Answer

Vertical axis accelerometer data is double-integrated over flight time to estimate jump height in IMU-based systems.

Question 2

In GPS-based athlete monitoring, what does the term 'metabolic power' estimate during sport activity?

Accepted Answer

Energy expenditure derived from velocity and acceleration data

Answer

Metabolic power models use instantaneous velocity and acceleration from GPS to estimate energy expenditure per unit time.

Question 3

A performance scientist uses an optical motion capture system with 16 cameras. What is the primary purpose of calibrating the capture volume before data collection?

Accepted Answer

To establish a shared 3D coordinate system across all cameras

Answer

Calibration defines a common 3D reference frame so each camera's 2D image data can be reconstructed into accurate 3D positions.

Question 4

Which blood flow restriction (BFR) technology metric is standardized to minimize inter-individual variation in cuff pressure?

Accepted Answer

Limb occlusion pressure percentage

Answer

Setting BFR pressure as a percentage of limb occlusion pressure (LOP) accounts for individual differences in limb circumference and arterial pressure.

Question 5

In near-infrared spectroscopy (NIRS) for muscle oxygenation monitoring, what does the SmO2 parameter represent?

Accepted Answer

Muscle tissue oxygen saturation percentage

Answer

SmO2 is the percentage of hemoglobin and myoglobin that is oxygenated within the muscle tissue being measured.
