Resumo

We aimed to investigate if social networks measures can be used as indicators of training tasks' adjustment level to soccer players' tactical skills. Twenty-four U17 male soccer players (16.89 +/- 0.11 years) participated in this study. The System of Tactical Assessment in Football (FUT-SAT) was used to identify players' tactical level and to organize them into three groups: Higher tactical level (Group 01), Intermediate tactical level (Group 02) and Lower tactical level (Group 03). Then, the players performed three High difficulty Small-Sided and Conditioned Games (HD-SSCG) and three Low difficulty Small-Sided and Conditioned Games (LD-SSCG). Teams' interaction patterns and players' prominence were analysed based on macro (Density - D and Clustering coefficient - CC) and micro networks (Indegree, Outdegree, Total links and Eigenvector) measures. We found that Group 01 presented higher D (p = .004 and ES = 1.189) and CC (p =.004 and ES = .785) at HD-SSCG than Group 03, whereas Group 03 presented higher values of D (p = .003 and ES = 1.200) and CC (p = .037 and ES = 1.180) at LD-SSCG than Group 01. When training tasks difficulty were adjusted to players' tactical level, teams played more collectively and players were more actively engaged in ball circulation. We concluded that macro and micro networks measures can be applied in training context as indicators of training tasks adjustment to players' tactical level. (AU)
