Description
Avg. GCT Bal.
The average ground contact time balance for the current session.
Avg GCT
The average amount of ground contact time for the current activity.
Avg. Stride Len. The average stride length for the current session.
Avg. Vert. Osc. The average amount of vertical oscillation for the current activity.
Avg. Vert. Ratio The average ratio of vertical oscillation to stride length for the current session.
GCT Balance
The left/right balance of ground contact time while running.
The amount of time in each step that you spend on the ground while running, measured in
GCT
milliseconds. Ground contact time is not calculated while walking.
Lap GCT Bal.
The average ground contact time balance for the current lap.
Lap GCT
The average amount of ground contact time for the current lap.
Lap Stride Len. The average stride length for the current lap.
Lap Vert. Osc.
The average amount of vertical oscillation for the current lap.
Lap Vert. Ratio The average ratio of vertical oscillation to stride length for the current lap.
Stride Length
The length of your stride from one footfall to the next, measured in meters.
The amount of bounce while you are running. The vertical motion of your torso, measured in
Vertical Osc.
centimeters for each step.
Vertical Ratio
