“…RESULTS: The top-ranked team covered greater total distance [median (interquartile range); 10,330.0 m (1430.0)] and high-acceleration [97.0 m (32.0)] than the bottom-ranked team, in home and away matches [p < 0.05, effect size (ES) = small]. The midfielders of the top-ranked team covered higher total distance, high-speed running (> 18 km h(−1)), high acceleration (≥ 3 m s(−2)), high-deceleration (≤ −3 m s(−2)), and performed more sprints [(> 25 km h(−1)) compared to midfielders of the bottom-ranked team (p < 0.05, η(2) = small-moderate]. …”

“…Main findings are that central-attacking midfielders (CAM) and central midfielders (CM) expended more energy (CAM: 59.8 ± 4.2 kJ kg(−1); CM: 59.6 ± 3.6 kJ kg(−1)) and covered more distance (CAM: 11,494 ± 765 m; CM: 11,445 ± 638 m) than all other positions (p < 0.001). …”

Significant (p < 0.0001) differences were also noted between maximum BiP phases and averaged data across all 4 quarters, for each microsensor metric, and all playing positions. …”

“…The following variables were analysed: total distance covered by the team, distance covered by individual players, maximum running speed and average match running speed for the team and individual players, as well as with division with regard to playing position: defenders, midfielders, strikers. In comparison to the four best teams at the football World Cup of 2010, the Korea Republic players achieved the highest running speed (p≤0.05), and similar levels of covered distance and average match running speed.…”

“…This revealed that the general properties of cooperation increased with the competitive level, improved during the middle of the season and were better in home matches. Midfielders were most prominent players in elite and U19 teams in the mid-season and central defenders had the most prominent centralities in U17 and U15 during the early and late periods of the season.…”
