This study analyses the influence of different area per player (A; 75, 98 and 131 m) on the average metabolic power (MP) and other soccer-related performance variables in relation to the positional roles. We recruited 19 non-professional male soccer players (25.2 ± 6.3 y; 23.7 ± 2.3 kg/m; 16.4 ± 6.3 y soccer experience) to play three different small-sided games (SSGs): SSG1 (5 vs. 5; 30 × 30 m; 5 min), SSG2 (5 vs. 5; 35 × 45 m; 5 min) and SSG3 (7 vs. 7; 35 × 45 m; 8 min). Specific playing rules were applied. GPS-assessed soccer-related variables were: average MP (AMP), distance covered in 1 min (DIS); % time spent at high speed (v > 16 km/h; % hst) or MP (>20 W/kg; % hmpt); % distance covered at high positive/negative speed (2 < v < 4 m/s, % ACC; -6 < v < -2 m/s, % DEC); and number of actions at high MP (hmpa). All recorded variables differed when each SSG was compared to the others ( < 0.05), but for hmpa for attackers. Most performance variables were positively associated with increasing A ( < 0.05), but for % ACC and % DEC, and differed among positional roles within the same SSG ( < 0.05). Here the general applicability of SSGs, regardless the physical/technical skills of the group of players, to enhance performance is confirmed; furthermore, quantitative advices on AMP and other performance variables are provided to achieve significant improvements in all soccer players of the team.
本研究分析了不同球员区域密度（A；75、98 和 131 平方米）对平均代谢功率（MP）和与位置角色相关的其他足球相关表现变量的影响。我们招募了 19 名非职业男性足球运动员（25.2 ± 6.3 岁；23.7 ± 2.3 公斤/平方米；16.4 ± 6.3 年足球经验）参加三种不同的小场比赛（SSG）：SSG1（5 对 5；30 × 30 米；5 分钟），SSG2（5 对 5；35 × 45 米；5 分钟）和 SSG3（7 对 7；35 × 45 米；8 分钟）。应用了特定的比赛规则。GPS 评估的足球相关变量包括：平均 MP（AMP）、1 分钟内覆盖的距离（DIS）；高速时间百分比（v > 16 公里/小时；%hst）或 MP（>20 W/kg；%hmpt）；高速正/负速度覆盖距离百分比（2 < v < 4 m/s，%ACC；-6 < v < -2 m/s，%DEC）；高 MP 动作次数（hmpa）。当将每个 SSG 与其他 SSG 进行比较时，所有记录的变量都有所不同（<0.05），但攻击者的 hmpa 除外。大多数表现变量与 A 的增加呈正相关（<0.05），但对于%ACC 和%DEC，并且在同一 SSG 中的不同位置角色之间有所不同（<0.05）。这里证实了 SSG 的普遍适用性，无论球员群体的身体/技术技能如何，都可以提高表现；此外，还提供了有关 AMP 和其他表现变量的定量建议，以实现团队中所有足球运动员的显著进步。
