Figures & data

Figure 1. Group average mental wellbeing scores across the 2019–2020 and 2020–2021 season.

Table 1. Absolute GPS parameters, previous 7-day, 14-day and 21-day training load (mean ± SD).

Training load	Previous 7-day	Previous 14-day	Previous 21-day
Session duration (min)	242 ± 68	492 ± 85	700 ± 147
Total distance (m)	20,909 ± 6156	42,960 ± 9970	63,106 ± 13,809
Low-intensity distance (m)	19,888 ± 5851	40,881 ± 9489	62,004 ± 13,577
Explosive distance (m)	1345 ± 437	2716 ± 677	3988 ± 967
High-speed distance (m)	831 ± 327	1690 ± 556*	2539 ± 807
Sprint distance (m)	190 ± 129	388 ± 220	551 ± 277*

Note: Low intensity distance (0–5.5 m/s), Explosive Distance (accelerating and decelerating > 2 m/s²), high-speed distance (5.5–7 m/s) and sprint distance (>7 m/s). *Reveals a statistical significance.

Illness (% of time with an illness)	1.4 ± 3.1	1.4 ± 2.0	1.3 ± 1.8
Match selection (% of matches selected for)	76.0 ± 2 6.4	75.1 ± 25.5	74.9 ± 24.8
Individual win rate (% of games won)	25.0 ± 17.3	23.9 ± 13.3	25.5 ± 8.5
Playing status (% of games started or subbed)	76.6 ± 23.2	72.7 ± 22.9	70.1 ± 21.6
