Question 1

In velocity-based training, an individual load-velocity profile is constructed by:

Accepted Answer

Plotting mean bar velocity against increasing percentages of 1RM across multiple loads

Answer

The load-velocity profile establishes a linear relationship between % 1RM and bar velocity, enabling coaches to estimate and adjust daily training loads from velocity alone.

Question 2

The acute:chronic workload ratio (ACWR) is primarily applied by strength and conditioning coaches to:

Accepted Answer

Identify athletes at elevated injury risk due to rapid spikes in workload

Answer

ACWR compares the previous week's load (acute) to the rolling 4-week average (chronic); ratios above ~1.5 are associated with increased injury risk due to insufficient adaptation time.

Question 3

A primary limitation of heart rate monitors when used to quantify load during resistance training is:

Accepted Answer

Heart rate response is confounded by non-aerobic factors such as Valsalva maneuver and large muscle mass involvement

Answer

During heavy resistance training, cardiac output is also driven by intrathoracic pressure changes, isometric tension, and pressor response — not solely aerobic energy demand — inflating load estimates.

Question 4

An inertial measurement unit (IMU) combines data from which combination of sensors?

Accepted Answer

Accelerometer, gyroscope, and magnetometer

Answer

IMUs fuse tri-axial accelerometer (linear acceleration), gyroscope (angular velocity), and magnetometer (orientation relative to Earth's magnetic field) data to estimate full 3D motion.

Question 5

The limb symmetry index (LSI) calculated from unilateral force plate testing is expressed as:

Accepted Answer

(Weaker limb / stronger limb) × 100

Answer

LSI = (weaker/involved limb ÷ stronger/uninvolved limb) × 100; a score of ≥90% is commonly used as a return-to-sport criterion following lower-limb injury.
