Speed and Distance Metrics can be viewed in either metric or imperial units. These can be changed in the Settings menu in VX View.
Activity Load 2D/3D (ActivityLoad 2D/3D)
This metric is available as either 2D or 3D. It is a measure of net cumulative motion calculated for the X, Y & Z accelerometers. The value of AL2D and AL3D will typically be between 200 and 500, depending on the length of the session recorded and the intensity. It is available for both indoor and outdoor activities and is proportional to athletic cumulative physical effort. The AL3D metric will suit most field-based sports where significant running or jumping is involved. For the AL2D metric only the X&Y axes are used, and this version is more relevant to athletic activities that do not have significant running.

Athlete Load (Athlete Load)
Calculated by the relationship between Duration Total, Distance Total, High Intensity Distance and Total Sprints. Normative data gathered from elite & College Soccer (Football). An Athlete Load of 80 points would be considered a match load, 70 would be less and 90 would be more.
