Question 1

In velocity-based training (VBT), which device commonly attaches to a barbell with a tether to measure bar speed?

Accepted Answer

Linear position transducer

Answer

A linear position transducer tracks the tether's displacement over time to calculate bar velocity.

Question 2

In velocity-based training, what happens to bar velocity as the load approaches an athlete's 1-repetition maximum?

Accepted Answer

It decreases

Answer

The load-velocity relationship is inverse: heavier loads move more slowly.

Question 3

Why would a coach record sprint technique at 240 frames per second instead of 30?

Accepted Answer

To capture brief events like ground contact with less motion blur

Answer

Higher frame rates capture fast movements in more detail for slow-motion analysis.

Question 4

The original Borg Rating of Perceived Exertion (RPE) scale ranges from:

Accepted Answer

6 to 20

Answer

Borg's original scale runs from 6 to 20 to roughly match heart rate divided by 10.

Question 5

How is session RPE (sRPE) training load calculated?

Accepted Answer

Session RPE multiplied by session duration in minutes

Answer

Foster's sRPE method multiplies the session rating by its length in minutes to give arbitrary load units.
