In velocity-based training (VBT), which device commonly attaches to a barbell with a tether to measure bar speed?
Answer: Linear position transducer
A linear position transducer tracks the tether's displacement over time to calculate bar velocity.
In velocity-based training, what happens to bar velocity as the load approaches an athlete's 1-repetition maximum?
Answer: It decreases
The load-velocity relationship is inverse: heavier loads move more slowly.
Why would a coach record sprint technique at 240 frames per second instead of 30?
Answer: To capture brief events like ground contact with less motion blur
Higher frame rates capture fast movements in more detail for slow-motion analysis.
The original Borg Rating of Perceived Exertion (RPE) scale ranges from:
Answer: 6 to 20
Borg's original scale runs from 6 to 20 to roughly match heart rate divided by 10.
How is session RPE (sRPE) training load calculated?
Answer: Session RPE multiplied by session duration in minutes
Foster's sRPE method multiplies the session rating by its length in minutes to give arbitrary load units.
Using athlete-monitoring software, an acute:chronic workload ratio in which range is often called the 'sweet spot' for lower injury risk?
Answer: About 0.8 to 1.3
Research has linked ratios of about 0.8–1.3 with lower injury risk, while spikes above roughly 1.5 raise it.
Accelerometer-based 'player load' metrics in team-sport GPS vests mainly measure:
Answer: Accumulated changes in acceleration across three movement axes
These metrics add up triaxial acceleration changes to capture work like cutting, jumping, and collisions.
