Th is study aimed to explore the eff ects of previous instruction on technical, tactical and external workload performances in football small-sided games. Two 7-a-side balanced competitive teams received instructions regarding the rules of the small-sided games proposed. Additionally, one team received instructions from the coach regarding the collective tactical behaviour required for each exercise condition: (a) Without strategic instruction (WSI); (b) Defensive strategy (DS); (c) Off ensive strategy (OS) to play against the team that only received the rules of the small-sided games. Th e comparisons among game scenarios were assessed via standardised mean diff erences. Th e comparison between WSI and DS revealed higher number of defensive actions, less space covered, and more distance covered in jogging for DS in comparison with WSI. Th e comparison between WSI and OS revealed more passes per ball possession, larger team length, larger space covered, lower distance covered walking, and more distance covered in jogging for OS in comparison with WSI. Th e results reinforce that coaches’ previous instruction constrains the technical, tactical, and physical demands of small-sided games in football. Th e use of previous instruction regarding strategical and tactical behaviour allows highlighting the players’ behaviour and ensures functional team performance.

教练指导对足球小游戏中技术动作，战术行为和外部工作量的影响

本研究旨在探讨先前的指导对足球小型比赛中的技术，战术和外部工作量表现的影响。两个由7人组成的平衡比赛团队收到了有关拟议的小型比赛规则的说明。另外，一个团队从教练那里收到了有关每种锻炼条件所需的集体战术行为的指导：（a）没有战略指导（WSI）；（b）防御战略；（c）与只接受小型比赛规则的球队对抗的激动策略。通过标准化的均值差异评估了游戏场景之间的比较。WSI和DS的比较显示，与WSI相比，DS慢跑时的防御动作次数更多，覆盖的空间更少，距离也更长。WSI与OS的比较显示，与WSI相比，OS的每球拥有更多的传球次数，更大的球队长度，更大的空间覆盖，更低的步行覆盖距离以及慢跑所覆盖的距离。结果进一步表明，教练的先前指导限制了足球小型比赛的技术，战术和身体要求。通过使用先前有关战略和战术行为的说明，可以突出显示玩家的行为并确保团队运作正常。和足球小型比赛的身体需求。通过使用先前有关战略和战术行为的说明，可以突出显示玩家的行为并确保团队运作正常。和足球小型比赛的身体需求。通过使用先前有关战略和战术行为的说明，可以突出显示玩家的行为并确保团队运作正常。
