Summary

There is a great need to establish reliable evaluation and intervention protocols to improve the tactical component, decision making (DM) and procedural tactical knowledge (PTK) in soccer. Objectives: to determine the effects of a 12-week follow up numerical superiority and numerical inferiority tactical training program on PTK, which will be evaluated by calculating offensive, defensive and global effectiveness indexes (EI) of 24 amateur male soccer players, as well as the effect on their executive functions. Method: randomized controlled trial, with two groups in parallel, experimental group (EG) and control group (CG), with different measurements over time (pretest, intermediate test 1, intermediate test 2 and posttest).

Detailed description

Program characteristics: training frequency 5 times/week, 1 competition, frequency of stimulation of small side games (SSGs) and technical-tactical actions (ATT) of numerical superiority and inferiority 2 times/week, specific training time 30 to 42 minutes/session. The PTK will be evaluated through the Football Competence Observation System (FOCOS). Data analysis: Shapiro-Wilk will be applied and according to the results, the data will be summarized with means and standard deviation or with medians and interquartile ranges. A repeated measures design will be performed using ANOVA and MANOVA will also be performed. In addition, the assumption of homogeneity of the variances will be evaluated based on the Levene statistics. For executive functions, intragroup analysis will be performed using dependent Student's t-test or Wilcoxon. For intergroup analysis, t student for independent samples or U Mann Withney will be applied. Confidence intervals (CI95) and effect sizes for two tails will be reported, with an alpha (α) set at 0.05 and statistical power of 0.8 (1-β). Statistical significance (p≤0.05). SPSS version 27 and R version 4.0 will be used. Ethical aspects: the guidelines of the Declaration of Helsinki (2013) and the Ministry of Health and Social Protection (resolution 8430/1993) will be followed, this research is of minimal risk.

Interventions

Type	Name	Description
BEHAVIORAL	Tactical training in numerical superiority and numerical inferiority	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.
BEHAVIORAL	Conventional training in numerical equality	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.
