Our aim was to analyze the effect of mental fatigue caused by prolonged social media use on high-level volleyball players' visuomotor skills. Eighteen high-level male young volleyball players participated in this randomized, counterbalanced, crossover design. All participants underwent a 2-week experiment in which we measured their response times when performing a visuomotor task with and without mental fatigue inducement through repeated use of social media immediately before training sessions. In the control condition, participants watched TV for 30-minutes, and in the social media condition, they used a social media app (Instagram) on smartphones for 30-minutes. We found a significant Condition x Time interaction on visuomotor task response time ( = 0.03), but there was no significant main effect of either Time or Condition. Mental fatigue, induced by repeated app-based social media use for 30-minutes immediately before training sessions, affected elite male volleyball players' visuomotor skills.
我们的目的是分析长时间使用社交媒体导致的精神疲劳对高水平排球运动员视觉运动技能的影响。18名高水平男性青年排球运动员参与了这项随机、平衡、交叉设计的研究。所有参与者都经历了为期2周的实验，在此期间，我们测量了他们在训练前立即通过反复使用社交媒体诱导出精神疲劳和未诱导精神疲劳两种情况下执行视觉运动任务时的反应时间。在对照条件下，参与者观看30分钟电视，在社交媒体条件下，他们在智能手机上使用一款社交媒体应用程序（照片墙）30分钟。我们发现视觉运动任务反应时间上存在显著的条件×时间交互作用（=0.03），但时间或条件的主效应均不显著。在训练前立即通过基于应用程序反复使用社交媒体30分钟诱导出的精神疲劳，影响了精英男性排球运动员的视觉运动技能。
