Table 1
Definition of GPS variables
| Variable | Definition |
|---|---|
| TD | Total distance covered (m): this includes walking, jogging, fast running and sprinting |
| HSD | Total distance covered (m) above 20 km/h |
| TL | Total of the forces on the player over the entire session based on accelerometer data alone
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. |
| ACC | A 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.
