Total Loading
The sum of the magnitude of the instantaneous changes across all of the axes of the tri-axial accelerometer data that is recorded. The resultant value is divided by 1000 to give manageable values.
Total load provides a volume measure of how much total work a player has completed during a session. This is a particularly useful metric for sports that involve a lot of physical exertion at lower speeds, such as American Football and Rugby. Intense actions such as jumps, collisions, falls, rucks, and tackles that are not typically quantified by speed measurements can be accounted for via the incorporation of this metric in analysis.
Lower Speed Loading
Lower Speed Loading isolates the accelerometer activity when speed is below 2m/s.
It measures the Total Loading value when speed is below 2m/s. This will help to isolate low speed, high collision activity such as rucking, tackling & line of scrimmage activity in American Football or Rugby.
Dynamic Stress Load
The sum of the magnitude of the tri-axial accelerometer data above 2G forces, raised to a body load factor and scaled to manageable values. It weights the impacts using a convex-shaped function.
Total Acceleration Loading
Dynamic Stress Load values during acceleration events.
Total Deceleration Loading
Dynamic Stress Load values during deceleration events.
