performances were measured using Global Positioning System (GPS) units across 1 competitive season. Matches were comprised of 4 × 20-minute quarters with no time-on added to the game clock. The dichotomization of data was completed into 3 phases. First, each player’s data were categorized into 3 different

profiles were measured using global positioning system (GPS) units during 14 matches. All participants completed 2 field sessions per week with their respective clubs during the preseason. This project was completed in 3 phases. First, the sample was separated into selected and nonselected players for the

mathematical constraints. • Match demands were taken from the 2015 AFL GPS Report 14 and incorporated by constraining the total match distance to be 13,200 m ( w 125  = 13,200). This is an average value and may not reflect the largest loads seen in matches or the differences between playing positions. By

, players’ HR was assessed through 20-Hz portable HR monitors and global positioning systems (GPS; Polar Team Pro, Kempele, Finland). GPS units with a frequency of 10 Hz were used; the accelerometers inside the GPS units had a frequency of 100 Hz. No control subject participated in this observational study
