  • Cadence: number of steps per minute
  • Vertical oscillation: degree of bounce in your running motion; displays the vertical motion of your torso, measured in centimeters for each step
  • Ground contact time: amount of time in each step that you spend on the ground while running; measured in milliseconds
  • Ground contact time balance: displays the left/right balance of your ground contact time while running (displays a percentage); for example, 53.2 with an arrow pointing left or right
  • Stride length: length of your stride from 1 footfall to the next; measured in meters
  • Vertical ratio: ratio of vertical oscillation to stride length (displays a percentage); a lower number typically indicates better running form
