Table 1 Synthesis of the variables used

From: Sports teams as complex adaptive systems: manipulating player numbers shapes behaviours during football small-sided games

Players’ dispersion (overall) Stretch index measure of all players on the field. It provides a measure of compactness of the team
Players’ dispersion in the goal-to-goal direction Stretch index measure of all players on the field in the longitudinal direction
Players’ dispersion in the side-to-side direction Stretch index measure of all players on the field in the lateral direction
Teams’ separateness Measure of the degree of free movement each team has available. It provides an estimate of the amount of space separating the players of both teams
Time delay between teams’ movements in the goal-to-goal direction Quantifies the existing time delay between both teams’ movements using each team centroid as a reference. It represents the delay of teams in adjusting to each other’s movements in the longitudinal direction of the field
Time delay between teams’ movements in the side-to-side direction Quantifies the existing time delay between both teams’ movements using each team centroid as a reference. It represents the delay of teams in adjusting to each other’s movements in the lateral direction of the field
Coupling strength in the goal-to-goal direction It measures the degree of coordination or synchronization between the teams’ movements in the longitudinal direction of the field
Coupling strength in the side-to-side direction It measures the degree of coordination or synchronization between the teams’ movements in the lateral direction of the field
