Key Features
- Cadence: number of steps per minute
- Vertical oscillation: degree of bounce in your running motion; shows 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: shows 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 one 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
