IMU Step was designed to measure & manage lower limb load in running based sports e.g. running, basketball, soccer. It is particularly useful for lower limb injuries since you can precisely measure and therefore manage lower limb load for both legs.
It is also useful for indoor running sports such as basketball, volleyball and netball since it quantifies every step taken & does not require a connection to a satellite.
It is also useful to quantify load in running sports based sports played in confined spaces such as tennis, american football & small sided soccer games.
