The aim was to compare the running activity in official matches with that achieved in two small-sided games, designed with the same relative area per player but with different constraints and field dimensions, aiming to stimulate high-speed and very-high-speed running. Seventeen young professional players played one 5 . 5+5 with 2 floaters, varying in terms of whether there was a change of playing area (SSG) or not change (SSG). Running activity was monitored using GPS and the following variables were recorded: total distance covered; high-speed distance (18-21 km·h); very high-speed distance (>21 km·h); peak speed; accelerations and decelerations between 2-3 m·s and above 3 m·s. SSG achieved statistically higher total distance, high-speed, peak speed and number of accelerations and decelerations than SSG (large to small magnitude). Both drills showed statistically greater high speed, number of accelerations and decelerations than official matches (large to small magnitude). Moreover, SSG exhibited statistically more total distance and distance at higher speed than official matches (moderate and small magnitude, respectively). In contrast, official matches showed statistically higher peak speeds than both training tasks and more very high speed than SSG (large and moderate magnitude, respectively). Coaches could use SSG to promote greater running activity in soccer players.
目的是比较正式比赛中的跑动活动与通过设计具有相同的球员相对面积但具有不同约束和场地维度的两个小场比赛中的跑动活动，旨在刺激高速和超高速度跑动。17 名年轻职业球员参加了一场 5 对 5+2 名游击手的比赛，根据是否改变比赛区域（SSG）或不改变比赛区域（SSG）进行了分组。使用 GPS 监测跑动活动，并记录了以下变量：总跑动距离；高速跑动距离（18-21km·h）；超高速度跑动距离（>21km·h）；最高速度；2-3m·s 和大于 3m·s 的加速度和减速度。SSG 在总跑动距离、高速跑动距离、最高速度和加速减速次数方面明显高于 SSG（大小从大到小）。两个训练项目的高速跑动距离、加速减速次数均明显高于正式比赛（大小从大到小）。此外，SSG 的总跑动距离和高速跑动距离明显高于正式比赛（分别为中等和小幅度）。相比之下，正式比赛的最高速度明显高于两个训练项目，超高速度跑动距离明显高于 SSG（分别为大、中幅度）。教练可以使用 SSG 来提高足球运动员的跑动活动量。
