Box plots for comparison of whole game averaged (WG) per quarter vs maximum ball in play (BIP) phases per quarter for all playing positions combined. Key; HSR: high-speed running (> 18 km·h−1), VHSR: very high-speed running (> 24 km·h−1), HIE: high-intensity efforts (> 18 km·h−1 for ≥ 2 s), PL: PlayerLoad™, Accelerations: (> 3 m·s−2). WG (Q1): 1st quarter, WG (Q2): 2nd quarter, WG (Q3): 3rd quarter, WG (Q4): 4th quarter
