Baptista, J, Travassos, B, Gonçalves, B, Mourão, P, Viana, JL, and Sampaio, J. Exploring the effects of playing formations on tactical behavior and external workload during football small-sided games. J Strength Cond Res 34(7): 2024-2030, 2020-This study aimed to identify the effects of playing formations on tactical behavior and external workload during football small-sided games. Twenty-three semiprofessional footballers integrated 3 different playing formations in a 7-a-side small-sided game, according to their specific player positions: team 4:3:0 (4 defenders and 3 midfielders); team 4:1:2 (4 defenders, 1 midfielder, and 2 forwards); and team 0:4:3 (4 midfielders and 3 forwards). Based on players' movement trajectories, the following individual and collective tactical variables were calculated: total distance covered and distance covered while walking, jogging, running, and sprinting, distance from each player to both own-team centroid and opponent-team centroid, individual area, team length, team width, and surface area. Approximate entropy was computed to identify the regularity of each variable. The team 4:3:0 promoted players' space exploration with moderate physical efforts. The team 4:1:2 promoted compactness and regularity of the team with increase in the physical efforts. The team 0:4:3 promoted team balance and adaptability on space coverage with increase in physical efforts. Concluding, different playing formations support different game dynamics, and variations on external load were directly linked with the variations on tactical behavior. The analysis of tactical behavior through quantification of variability of patterns of play and quantification of distance covered at different velocities were the most useful information for the analysis of the effects of practice task manipulations. Therefore, in a practical sense, strength and conditioning coaches should plan and monitor these tasks in interaction with the head coaches.
巴蒂斯塔、J、特拉瓦索斯、B、贡萨尔维斯、B、莫劳、P、维亚纳、JL 和桑帕约、J. 探究在足球小场比赛中，不同的比赛阵型对战术行为和外部工作负荷的影响。J 力量与体能研究 34(7):2024-2030, 2020-本研究旨在确定在足球小场比赛中，不同的比赛阵型对战术行为和外部工作负荷的影响。23 名半职业足球运动员根据他们的特定球员位置，在一个 7 对 7 的小场比赛中融入了 3 种不同的比赛阵型：4-3-0 队（4 名后卫和 3 名中场球员）；4-1-2 队（4 名后卫、1 名中场和 2 名前锋）；0-4-3 队（4 名中场球员和 3 名前锋）。基于球员的运动轨迹，计算了以下个体和集体战术变量：总距离和步行、慢跑、跑动和冲刺时的距离，每个球员到本队质心和对方队质心的距离，个人区域、队的长度、队的宽度和表面积。近似熵被计算以确定每个变量的规律性。4-3-0 队促进了球员的空间探索，运动强度适中。4-1-2 队促进了团队的紧凑性和规律性，运动强度增加。0-4-3 队促进了团队在空间覆盖方面的平衡和适应性，运动强度增加。结论：不同的比赛阵型支持不同的比赛动态，外部负荷的变化与战术行为的变化直接相关。通过对比赛模式的变异性进行量化和对不同速度下的距离进行量化来分析战术行为，是分析练习任务操作效果的最有用信息。因此，在实践意义上，力量和体能教练应该与主教练一起计划和监控这些任务。
