32
Define: Cadence
Steps per minute
33
Define: Ground Contact Time
Time spent on the ground during stance phase.
34
Define: Vertical Oscillation
Vertical displacement during running (also called bounce).
35
Define: Strike from COM
Distance between Initial Contact on one limb and your Center of Mass.
36
Define: Foot Inclination

Lowering of non stance hip
40
Define: Trunk Lean
Angle created from the point of contact through the hip to the trunk
41
Define: Hip Seperation Angle
