: This study aimed to investigate if player tactical skill level and age category influence team performance and player exploratory behavior in tasks with different difficulty levels. : In total, 48 youth male soccer players participated in the study (U15, = 24, mean age = 13.06 ± 1.53 years; U17, = 24, mean age = 16.89 ± 0.11 years). Player tactical skills were evaluated through the System of Tactical Assessment in Soccer (FUT-SAT), allowing them to be organized into three groups according to tactical efficiency: Higher tactical skill level (Group 01), Intermediate tactical skill level (Group 02), and Lower tactical skill level (Group 03). Next, Group 01 and Group 03 of both categories performed six Small-Sided and Conditioned Games (SSCG) each, namely three High difficulty SSCGs and three Low difficulty SSCGs. Team performance and players' exploratory behavior were analyzed through the Offensive Sequences Characterization System and Lag Sequential Analysis, respectively. : We found that team performance and players' exploratory behavior were influenced both by the age and tactical skill level of the players, as well as by task difficulty level. : Therefore, in an attempt to improve player performance, practitioners must carefully manipulate key task constraints to adapt training task difficulty levels to player age and tactical skill level.
本研究旨在探讨球员战术技能水平和年龄类别是否会影响团队表现和球员在不同难度水平任务中的探索行为。共有 48 名青年男性足球运动员参加了这项研究（U15， = 24，平均年龄 = 13.06 ± 1.53 岁；U17， = 24，平均年龄 = 16.89 ± 0.11 岁）。球员的战术技能通过足球战术评估系统（FUT-SAT）进行评估，根据战术效率将他们分为三组：更高的战术技能水平组（Group 01）、中等的战术技能水平组（Group 02）和更低的战术技能水平组（Group 03）。然后，两个年龄段的 Group 01 和 Group 03 分别进行了六次小场和条件比赛（SSCG），即三个高难度 SSCG 和三个低难度 SSCG。团队表现和球员的探索行为分别通过进攻序列特征系统和滞后序列分析进行分析。我们发现，团队表现和球员的探索行为既受到球员年龄和战术技能水平的影响，也受到任务难度水平的影响。因此，为了提高球员的表现，教练必须仔细操纵关键任务约束条件，以适应训练任务的难度水平，以适应球员的年龄和战术技能水平。
