Most people who hear about force plates for the first time have a reasonable question: what does a force plate actually do, and why does it matter for coaching?
The answer is simpler than it might seem, and more consequential than most people expect.
What a force plate is
A force plate is a measurement device. You stand on it, move on it, jump on it, or swing on it, and it measures the forces you exert against it. Specifically, it measures ground reaction force, the force that the ground pushes back against your body in response to the force you apply to the ground.
Smart2Move’s 3D Dual Force Plates measure this force across three axes simultaneously, on both feet independently, at a sampling rate that captures the precise timing of every force event during a golf swing. The result is a complete picture of what your body is doing at the ground, frame by frame, with millisecond precision.
What force plates actually measure
A force plate does not measure your swing. It measures the ground forces that create your swing.
This distinction matters. Your swing is the visible output of a movement. The ground forces are the invisible input that drives that movement. By measuring the input, a coach can understand the cause of what they are seeing, rather than just describing the effect.
The three primary measurements are vertical force, anterior-posterior force, and lateral force. Each has a specific role in the golf swing, and each can be measured independently for each foot. This gives a coach six simultaneous data streams during a single swing, providing a complete picture of the ground mechanics that no other tool can match.
Beyond the three axes of force, S2M’s analysis also captures the Point of Application, the exact location on the foot where the force is being applied at any given moment during the swing. This data reveals pressure distribution patterns that are invisible even to the most experienced coaches observing a swing in person.
What force plates cannot do
Understanding the limits of force plate measurement is as important as understanding its capabilities.
A force plate cannot tell you what your swing looks like. It does not capture video. It does not measure club path, face angle, or ball flight. It measures only what is happening at the ground.
This is why force plate analysis works best when combined with other coaching tools. The force plate provides the input data. Video provides the visual output. Together they give a coach a complete picture: what the player is doing at the ground, and what that produces at the club.
A force plate also cannot prescribe a fix. It can identify a timing issue with millisecond precision, but translating that finding into a drill that a player can actually train requires coaching expertise. This is where certified S2M coaches add critical value, and where S2M Intelligence assists by bridging the gap between raw data and actionable recommendations.
Why this matters for coaching
Before force plates, golf coaching was almost entirely observational. Coaches developed extraordinary skill at reading body positions and movement patterns. But they were always working from the output backward, trying to infer the cause from the effect.
Force plates reversed the direction of analysis. Instead of watching what a player does and guessing why, a coach can now measure why and then watch what it produces. The diagnosis becomes more precise. The training becomes more targeted. The results come faster.
A junior coach using force plates with S2M Intelligence on their first day has access to a level of analytical precision that an expert coach without force plates cannot match, no matter how many years of experience they have. Not because the tool replaces expertise. But because it gives expertise better raw material to work with.
The accessibility shift
For most of the history of force plate coaching, this technology was limited to elite environments. University biomechanics labs. National team facilities. Tour player training centers.
Smart2Move changed that. Wireless, portable, field-ready force plates that a coach can carry in a bag to any lesson, on any course, in any country. And now, with S2M Intelligence and Kimi, the analytical layer that makes sense of the data is accessible to coaches at every level.
The technology is no longer the barrier. The knowledge is available. The question now is which coaches choose to use it.
