Jump Scan Force-Time Curve

A large variety of force-time derivatives (eg. mass, acceleration, velocity, power, impulse) can be calculated from time-series data. This provides a visual of the force-time curve from the Jump Scan and defines key phases and time points.

Force Plates

A Force Plate or platform is a device used to measure the forces exerted on the ground by a human body. Force plates can be thought of as high-powered bathroom scales because the devices themselves are relatively simple. The force plate device is instrumented with load cells that convert a force, such as pressure, into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally.

Data Types

Our data model describes the different levels of data that can be calculated utilizing the force plate, but at the simplest level, a force plate is designed to measure forces over a period of time. These two variables (force and time) are measured directly, and can then be utilized to calculate a variety of different metrics or variables based on Newtonian physics.

Force-Time Curve


The above visual shows a generic Jump Scan force-time curve illustration generated by plotting the time-series data.  Specific phases and points of interest are labeled above to provide a visual to better understand how the raw data metrics are calculated and what they potentially represent. It is important to note there are several different (and potentially inconsistent) terms for the variables below within other products or the literature.

The Raw Data metrics that show in the Sparta Movement Health Platform will contain a brief description/definition that can be pair with the above visual to best understand how the calculations are performed.  The terms we use are specific and consistent with the SMHP.
