Definition of GPS variables

TDTotal distance covered (m): this includes walking, jogging, fast running and sprinting
HSDTotal distance covered (m) above 20 km/h
TLTotal of the forces on the player over the entire session based on accelerometer data alone
Graphic where aca is acceleration along the anterior–posterior axis, acl is acceleration along the lateral axis and acv is acceleration along the vertical axis, i is current time and t is time. This is then scaled by 1000.
ACCA change in GPS speed data for at least half a second with maximum acceleration in the period of at least 0.5 m/s/s
  • ACC, accelerations; GPS, global positioning system; HSD, high-speed distance; TD, total distance; TL, total load.
