Vertical Landing Acceleration

Written By Plantiga Technologies
 

The peak accelerations in the world vertical plane as the foot contacts the ground. Vertical Landing Acceleration (VLA) is calculated for every step, and is a means of quantifying strategy used to absorb impact.

Illustration of difference between VLA and z-axis accelerations

Note that VLA is different from the z-axis signal, because the z-axis changes orientation as the foot moves through space. VLA is purely up and down.
