High Metabolic Load Distance (HMLD)
The distance travelled by a player when their Metabolic Power (Energy Consumption per Kilogram per Second) is above the value of 25.542 W/Kg.
This value of 25.542 W/Kg typically corresponds to when a player is running at a constant speed of 5.5m/s (default HSR speed in Sonra) on grass or when they are performing significant acceleration or deceleration activity, for example if they are accelerating from 2m/s to 5m/s within a 1 second period.
This results in the metric encapsulating the higher intensity physiological actions completed by the player.

The value of 25.542 W/Kg is a customisable value with Sonra on the general settings page (see below) and also on the individual player characteristics page.
Note - This metric can be used in addition to the Metabolic Distance metrics.
Example
- HMLD can be set with a desired threshold and used as a standalone metric.
- Metabolic Power zones can then be customised according to user preference (see below) and provide other metabolic sets of metrics including Metabolic Distance in Zones & Metabolic Time in Zones.
