摘要：This investigation examined match play physical performance across a professional football season using a multi-camera computerized tracking system. A linear mixed-effects model, controlling for situational and contextual variables, identified decreases in team average total distance (TD): season quarter 1 (Q1) (11047 m) > season quarter 2 (Q2) (10473 m) (P=0.002; ES=Small), season quarter 3 (Q3) (10449 m) (P<0.001; ES=Moderate) and season quarter 4 (Q4) (10385 m) (P Q3 (108 m/min) (P<0.001; ES=Moderate), Q4 (107 m/min) (P Q2 (65) (P Q4 (130 m) (P Q3 (165 m) (P=0.035; ES=Small), Q4 (130 m) (P Q3 (10.2) (P<0.001; ES=Moderate), Q4 (8.3) (P Q3 (10.2) (P<0.001; ES=Moderate), Q4 (8.3) (P Q4 in central defenders (13.1 vs 5.3) (P=0.014; ES=Large), wide defenders (21.6 vs 7.1) (P Q4 in wide defenders (16.3 vs 7.1) (P=0.005; ES=Very Large), central midfielders (16.9 vs 8.5) (P=0.004; ES=Large) and wide midfielders (20.8 vs 12.2) (P=0.007; ES=Large). Match-play physical performance reduced across the competitive season. The most notable reductions were observed in wide defenders, central midfielders and wide midfielders in sprint performance indices.
