One of the qualities of force, the tendency
to distort, is the reason force plates are able
to measure applied forces. When an athlete
applies any kind of force to the force plate,
sensors within the plate distort, causing measureable
voltage changes coming from the
sensors. In a properly constructed force plate,
these voltage changes are proportionate to
the magnitude of the forces applied. In many
force plates, sensors are configured in different
orientations allowing for the direction and
magnitude (i.e., vector) of the forces to be ascertained.
Important pieces of information can
be obtained from a modern, full-featured force
plate include:
• force in the X, Y, and Z directions,
• the centre of pressure,
• the centre of force,
• the moment (torque) around each of the
axes.
The data collected allows the investigator
to calculate a multitude of other variables from
the initial measures. For example, using trigonometry,
the magnitude and direction of applied
forces can be monitored.
