RUN

Running rate in steps per minute, and is a factor of speed (speed = 0.5 steps/min x stride length).

Often used as a coarse measure of external load

Correlates to running efficiency, as more efficient runners tend to have higher flight ratios.

The amount of time in a gait cycle in which both feet are off the ground.

A widely used metric for both athletic and clinical populations, as it relates to load while the foot is on the ground.

Correlated to lower running efficiencies.

A means of quantifying the strategy used to absorb energy.

A measure of the difference in Impact Accelerations between feet.

Can help give context to different training sessions of different lengths by normalizing the total load.

The percent difference between accelerations exerted on the left and right feet.

A means for quantifying the strategy used to push off the ground.

A measure of the difference in Push-off Accelerations between feet.

The amount of time the foot spends off the ground in the gait cycle

A measure of the difference in swing time between legs.

A measure of the consistency of swing time between strides.

Useful for workload monitoring to prevent injury and inform return to play decisions.
