Development of Tactical Decision-making Skills in Youth Soccer Players: Macro- and Microstructure of Soccer Developmental Activities as a Discriminant of Different Skill Levels

Decision-making in soccer is considered an important factor for soccer players achieve high-performance level. Studies in several sports indicated that tactical decision-making skills are necessary for skilful performance. We aimed to analyse whether soccer players with different levels of decision-making skills can be differentiated based on their engagement in various types and amounts of soccer activities during their development. The sample comprised 149 Brazilian youth male soccer players (M = 14.9, SD = 1.6 years). We examined the type and amount of soccer activities that contributed to distinguish players with different levels of offensive and defensive decision-making skills. Players' tactical decision-making skills were assessed with an objective video-based test (TacticUP (R) video test for soccer). We used a retrospective questionnaire to collect information about previous participation in different soccer developmental activities. The main activities that differentiated high/low skill groups in the macrostructure activities were: i) team practice; and in the microstructure: ii) collective tactics; and iii) high decision-making opportunities. We concluded that previous soccer developmental activities discriminate youth soccer players with different levels of decision-making skills. The main activities that differentiated high/low groups were: 1) team practice; 2) collective tactics in team practice, and; 3) high decision-making opportunities in team practice.
