This study investigates the effects of manipulating the number of ball touches (free play vs. two touches) on the physical and technical actions of elite male youth soccer players during 5v5 + 2 goalkeepers (GKs) small-sided games (SSGs).
Players played in two different SSGs: 1) free play, where the number of touches per possession was not restricted; and 2) two touches, where players were limited to a maximum of two touches per ball possession. A total of 24 male elite youth soccer players (age: 14.79±0.71 years; body mass: 56.02±1.41 kg; body height: 164±2.12 cm) participated in the study. Players' physical metric and technical performance data were captured using a global positioning system and video camera, respectively. A paired-samples t-test or Wilcoxon Signed-Rank Test was employed to examine differences in players' technical performance variables depending on SSGs' ball-touch rules.
The results show significantly more unsuccessful passes (t=-3.48; P=0.04; d=1.92) when players were limited to two touches than when there were no pass limits. The physical metrics indicate that total distance covered (Z=-2.90; P=0.001; d=0.07), meters per minute (Z=-3.44; P=0.001; d=0.11), low-speed running (Z=-2.25; P=0.02; d=0.04) and high acceleration (Z=-1.90; P=0.05; d=0.28) were significantly higher when touches were unlimited than when they were not.
Soccer coaches should decide the number of touches per ball possession they allow depending on their tactical and/or physical objectives in training.
本研究调查了在5对5 + 2名守门员（GK）的小型比赛（SSG）中，控制触球次数（自由发挥与两次触球）对精英男性青年足球运动员身体和技术动作的影响。
球员参加两种不同的小型比赛：1）自由发挥，每次控球的触球次数不受限制；2）两次触球，球员每次控球最多只能触球两次。共有24名男性精英青年足球运动员（年龄：14.79±0.71岁；体重：56.02±1.41千克；身高：164±2.12厘米）参与了这项研究。分别使用全球定位系统和摄像机采集球员的身体指标和技术表现数据。采用配对样本t检验或威尔科克森符号秩检验来检验取决于小型比赛触球规则的球员技术表现变量的差异。
结果显示，当球员被限制为两次触球时，不成功传球显著多于无传球限制时（t = -3.48；P = 0.04；d = 1.92）。身体指标表明，触球无限制时的总跑动距离（Z = -2.90；P = 0.001；d = 0.07）、每分钟跑动距离（Z = -3.44；P = 0.001；d = 0.11）、低速跑动（Z = -2.25；P = 0.02；d = 0.04）和高加速度（Z = -1.90；P = 0.05；d = 0.28）显著高于触球受限制时。
足球教练应根据训练中的战术和/或身体目标来决定每次控球允许的触球次数。
