Abstract：
Aerobic capacity plays a crucial role in football performance, making it a focal point in training processes. Small-sided games (SSGs) are widely used in football training, but the relationship between aerobic capacity and running performance during SSGs remains unclear. The aim of this study was to investigate possible correlations between maximum oxygen uptake (VO2max) and running performance in youth football players in SSGs (4:4, 3:3, 2:2, 1:1) with three different pitch sizes per player (150, 100, 75 m2/player). Sixteen male U15 football players participated in the study. Players underwent the Yo-Yo intermittent recovery test level 1, and their VO2max was estimated based on their performance. Subsequently, players participated in SSGs wearing GPS devices to measure internal and external load. Pearson or Spearman correlation was applied for statistical analysis depending on the normal distribution of the data. The results reveal that, for 4:4 and 3:3 relationships, larger pitches led to a greater impact of aerobic capacity (total distance (TD): 4:4, 150 m2/pl, r = 0.715, p = 0.002; 100 m2/pl, r = 0.656, p = 0.006; 75 m2/pl, r = 0.586, p = 0.017). In the 2:2 relationship, the opposite was observed, with more correlations appearing on smaller pitches (TD: 2:2, 100 m2/pl, r = 0.581, p = 0.018; 75 m2/pl, r = 0.747, p < 0.001). In the 1:1 relationship, correlations with VO2max, total distance, and speed were observed only on the larger pitch. In conclusion, the aerobic capacity of young football players can influence running performance indicators in SSGs. Therefore, aerobic capacity could serve as a criterion for team composition, making SSGs more competitive. Additionally, the variation in correlations in the 2:2 relationship and their limited presence in the 1:1 relationship may be attributed to technical-tactical factors, such as increased ball contacts and one-on-one situations typically occurring in smaller setups.
摘要：
有氧能力对足球的表现起着至关重要的作用,使其成为培训过程的重点。小面游戏(SSG)在足球训练中被广泛使用,但SSG期间有氧能力与跑步表现之间的关系尚不清楚。这项研究的目的是调查SSG（4：4，3：3，2：2，1：1）中青年足球运动员的最大摄氧量（VO2max）与跑步表现之间的可能相关性每个球员（150、100、75平方米/球员）。16名男性U15足球运动员参加了这项研究。玩家进行了Yo-Yo间歇性恢复测试1级，并根据他们的表现估算了他们的VO2max。随后，玩家参加SSG佩戴GPS设备来测量内部和外部负载。根据数据的正态分布，将Pearson或Spearman相关性用于统计分析。结果表明,对于4:4和3:3关系，较大的音高导致有氧能力的较大影响(总距离(TD):4:4,150m2/pl,r=0.715,p=0.002;100m2/pl,r=0.656,p=0.006;75m2/pl,r=0.586,p=0.017)。在2:2的关系中，观察到相反的情况，在较小的间距上出现更多的相关性(TD：2：2，100m2/pl，r=0.581,p=0.018;75m2/pl,r=0.747,p<0.001)。在1:1的关系中，与VO2max的相关性，总距离,和速度仅在较大的音高上观察到。总之,青少年足球运动员的有氧能力会影响SSG的跑步表现指标。因此,有氧能力可以作为团队组成的标准，使SSG更具竞争力。此外,2:2关系中的相关性变化及其在1:1关系中的有限存在可能归因于技战术因素，例如增加球接触和一对一的情况通常发生在较小的设置。
