Table 2.

Simplified categories of movement in relation to generalized body load and operational definitions used to visually assign movements into categories.

Movement category	Operational descriptors
Below bodyweight (B-BW)	-Activities that unweight the usual load of a player's body off their feet, which includes sitting, horizontal/lying on the ground (e.g., following a fall to the ground), or kneeling
Bodyweight (BW)	-Activity at no greater intensity than walking. Steps can be any direction: forward, backward, lateral. If steps are lateral, feet do not shuffle. See shuffle definition below for reference. -Includes leaning on an object (e.g., a stanchion or table) -Includes instances when player is in a defensive stance but not moving. -No flight phase: both feet never leave the ground. -Any time the player is off view from the camera or not participating in the drill and view is obstructed by the stanchion
Above bodyweight (A-WB)	-Any movement not within the definition of standing/walking or bench/sitting, which includes, pivoting, transitional movements/changing direction (e.g., cutting, jump-cuts), driving into another player, jogging, skipping, running, sprinting, shuffling (i.e., one foot replaces the position of the other within rough proximity), and jumping

Movement categories are based on estimated magnitude of ground reaction force loading at the feet in relation to bodyweight.
