How perceiving additional targets modifies teams' tactical behavior during football small-sided games

Area of Science:

• Sports Science
• Motor Control
• Human Movement

Background:

• Tactical behavior in team sports is influenced by task constraints.
• Small-sided games (SSGs) are effective training tools for developing tactical understanding.
• The impact of target manipulation on team dynamics in SSGs requires further investigation.

Purpose of the Study:

• To quantify the effect of varying target information on team tactical behavior in football SSGs.
• To analyze changes in team spatial dynamics and coordination under different target conditions.

Main Methods:

• Twenty senior professional male football players participated, divided into four teams of five.
• Players engaged in SSGs under two conditions: 2 official targets with a goalkeeper and 6 small targets.
• Player positional data were collected using 15Hz portable GPS, analyzing team center of gravity (CG) distance, stretch index, and relative stretch index.

Main Results:

• A moderate increase in the distance between team centers of gravity (CG) was observed with more targets.
• A small decrease in stretch index and relative stretch index indicated altered team formations.
• Tactical behavior modifications were more pronounced in lateral corridors and defensive sectors of the pitch.

Conclusions:

• Manipulating the number of targets in football SSGs significantly constrains and shapes team tactical behavior.
• Amplifying specific task information, such as increasing targets, can guide emergent team adaptations.
• Coaches can leverage target manipulation in SSGs to promote desired player and team behaviors.
