What factor is primarily measured by pressure plates in coaching?

• A. Ground force
• B. Club speed
• C. Ball distance
• D. Tee height

Answer: (A)

Pressure plates capture the force your body exerts on the ground and how that force changes throughout the swing. This tells you about ground reaction force, including loading and unloading of each leg and the timing of weight transfer from the back foot to the front foot. That ground interaction is what pressure plates are designed to measure, and it directly informs balance, stability, and the sequencing of movement critical to a solid swing.

The other measures aren’t what pressure plates provide: club speed comes from devices tracking the club’s velocity, ball distance depends on ball flight and carry, and tee height is a setup parameter, not a ground interaction metric.
