- Players between 17 and 26 years of age.
- Players with at least six months of experience in federated soccer.
- Players who do not present cognitive disorders that hinder learning, which can be identified through monitoring by coaches and/or tests conducted by the Neuropsychology staff.
- They must be affiliated to the contributory or subsidized health system.
- They must agree to participate in the study after knowing and signing the informed consent or assent, as appropriate.
Exclusion Criteria:
- Players with musculoskeletal disorders at the time of sample selection.

Experimental: Tactical training in numerical superiority and numerical inferiority
Participants will carry out a specific training program, with the objective of improving both offensive and defensive Tactical-Technical Actions (ATT) that will allow the increase of effectiveness indexes (EI) (offensive and defensive). The formats through which will train are Small Sided Games (SSGs) and ATT 2 against 1, 3 against 2 and 4 against 3 alternating them during the week (SSGs on Tuesdays and ATT on Thursdays). The characteristics of this training program are: training frequency 5 times/week, plus 1 competition on weekends, frequency of stimulation of the SSGs and ATT of numerical superiority and numerical inferiority 2 times/week, the specific training time assigned to the development of these formats and exercises will be 30 to 42 minutes/training session and will be carried out after the warm-up. |
In the present study, the SSGs training sessions will be carried out in the following areas: 2c1: length 11.5m and width 9m (total: 103.5m2), equivalent to 34.5m2 for each player. 3c2: length 14m and width 12m (total: 168m2), equivalent to 33.6m2 for each player. 4c3: length 17m and width 14m (total: 238m2), equivalent to 34m2 per each player. |
Active Comparator: Conventional training in numerical equality
On the other hand, the CG participants will perform conventional training. In the present study, conventional training is defined as ATTs performed in equal numbers in 1 against 1, 2 against 2 and 3 against 3 formats. Likewise, coaches will be asked not to carry out additional specific training with these formats, nor of SSGs or offensive or defensive ATT in numerical superiority and inferiority, specifically in 2 against 1, 3 against 2, or 4 against 3 formats, during the time of the study, to avoid confusion biases due to possible co-interventions. This CG training program will include individual, couples, and groups of three ATTs . The characteristics of this training program are: training frequency 5 times/week, 1 official competition on weekends, frequency of ATT stimulation in 1v1, 2v2 and 3v3 formats is 2 times/week, the specific training time allocated will be 40 minutes per training session and will be performed after the warm-up. |
Coach who will run the CG training program will be different from the coach who will run the GE training program.
As with the GE, a coach will also be assigned to the CG to record, quantify and monitor the training stimuli of this comparison group, who will record it on forms designed for this purpose.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Offensive Effectiveness Index (OEI). Scale for measuring the OEI ranges from 0 to 1 (0 being the worst score and 1 being the best score). These scores will be obtained by video analysis of 21 soccer players' tactical behaviors by the video analyst
Time Frame: 16 weeks
|
The OEI is determined through the following formula: OEI = Volume of successful tactical behaviors/Number of tactical behaviors developed in each category of analysis. OEI = Sum of the EI of the offensive tactical behaviors/Number of categories in which the player developed offensive tactical behaviors. |
16 weeks

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Defensive Effectiveness Index (DEI). Scale for measuring the DEI ranges from 0 to 1 (0 being the worst score and 1 being the best score). These scores will be obtained by video analysis of 10 soccer players' tactical behaviors by the video analyst.
Time Frame: 16 weeks
|
The DEI is determined through the following formula: DEI = Volume of successful tactical behaviors/Number of tactical behaviors developed in each category of analysis. DEI = Sum of the EI of the defensive tactical behaviors/Number of categories in which the player developed defensive tactical behaviors. |
16 weeks

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Executive Functions Measurements will be evaluated according to the number of hits and errors and the time taken to complete the evaluations (the better the one who presents more hits, fewer errors and performs the tests in the shortest time)
Time Frame: 16 weeks
|
Executive functions is a term used to describe cognitive processes that regulate thought and action such as problem solving, planning, sequencing, sustained and selective attention, inhibition, use of feedback, multitasking, cognitive flexibility and ability to deal with novel situations.
