The Athletic Shoulder (ASH) test, explained
The Athletic Shoulder (ASH) test measures shoulder strength on a force plate in three positions. Here's what it is, what it measures, and how to run it.
- The force formula (F=ma), explained
The force formula (F=ma), explained
The force formula is F = ma: force equals mass times acceleration. Here's what it means, how to calculate force, and how a force plate actually measures it.

What is force plate testing?
Force plate testing measures the force an athlete puts into the ground to reveal power, asymmetry and readiness. Here's what it is, who uses it, and the tests it covers.
- Rate of Force Development (RFD), explained
Rate of Force Development (RFD), explained
Rate of force development (RFD) is how fast an athlete produces force: explosive strength. Here's what it is, why it matters, and how a force plate measures it.
