- Cadence — the number of steps per minute. It displays the total steps (right and left combined).
- Vertical oscillation — the bounce in your running motion. It displays the vertical motion of your torso (measured in centimeters).
- Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
I'm not sure if we'll ever see all these metrics accurately captures from a wrist-based device (you can easily capture cadence, but I'm not sure about the vertical oscillation or ground contact time).
