Large-sided games (LSG) are commonly used in the training contexts for providing either technical/tactical or locomotor/physiological stimuli. Despite natural similarities with the official match, the locomotor profile seems to be different, which must be considered by the coaches to identify compensatory strategies for achieving the ideal dose of training. The aim of this study was two-fold: (1) to investigate the locomotor demands imposed by LSGs and the official matches; and (2) to compare the effect of different pitch sizes’ LSG conditions in the locomotor demands. This study followed an observational design. Sixteen professional football players from the same team (26.3 ± 3.0 years old) were included. The study was conducted over four weeks. The same GK + 10 × 10 + GK play format with different pitch sizes (i.e., area per player ranging between 195 m2 to 291 m2) was analyzed. Three official matches were also collected in which the 10 most demanding minutes were considered for further comparisons. Only the same players who participated in matches were considered in comparison with the LSG. The data were obtained using a 10-Hz global positioning system technology. Total distance (TD) and mechanical work (MW) scores increased 20% and 23%, respectively, between the smallest and biggest pitch sizes (p < 0.001). There was a significant difference in locomotor intensity metrics between opponents from different positions on the table (p = 0.001). The biggest LSG (i.e., 291 m2 per player) was the only one that required similar levels of locomotor intensity as required in the official full match. The present study demonstrates that LSG pitch size variation requires different locomotor intensities. Bigger pitch sizes cause an increase in TD and MW. In addition, considering the position on the table, the level of opponents induces different TD covered. Finally, the largest LSG simulates the official match more accurately.
大场比赛（LSG）常用于提供技术/战术或运动/生理刺激的训练环境中。尽管与正式比赛有自然相似之处，但运动模式似乎不同，教练必须考虑这一点，以确定实现理想训练剂量的补偿策略。本研究的目的有两个：（1）调查 LSG 和正式比赛所施加的运动需求；（2）比较不同场地大小的 LSG 条件对运动需求的影响。本研究采用观察设计。同一支球队的 16 名职业足球运动员（26.3 ± 3.0 岁）被纳入研究。研究共进行了四周。采用相同的 GK + 10 × 10 + GK 比赛模式，但场地大小不同（即每个球员的面积在 195 m2 到 291 m2 之间）。还收集了三场正式比赛，其中考虑了最具挑战性的 10 分钟进行进一步比较。只有参加比赛的相同球员被考虑与 LSG 进行比较。数据使用 10-Hz 全球定位系统技术获得。最小和最大场地大小之间，总距离（TD）和机械功（MW）分别增加了 20%和 23%（p < 0.001）。在桌面上来自不同位置的对手的运动强度指标存在显著差异（p = 0.001）。最大的 LSG（即每个球员 291 m2）是唯一需要与正式全场比赛相同运动强度的 LSG。本研究表明，LSG 场地大小的变化需要不同的运动强度。更大的场地会导致 TD 和 MW 的增加。此外，考虑到桌面上的位置，对手的水平会导致不同的 TD 覆盖。最后，最大的 LSG 更准确地模拟了正式比赛。
