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

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.

A means of quantifying the strategy used to absorb impact.

A means of quantifying the strategy used to absorb impact.

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.

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

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

Typically used for longer distance runs and pacing.

Typically be used for sprints and as a measure of power.

The resultant acceleration signal.
