The objective of this study was to analyze the effect of mental fatigue on mean propulsive velocity (MPV), countermovement jump (CMJ), 100, and 200-m dash performance in college sprinters. A total of 16 male athletes of sprint events (100 and 200-m dash) participated in this study. Each participant underwent two baseline visits and then running under the three experimental conditions. Assessments (MPV and CMJ) occurred both before and after either smartphone use (SMA) or Stroop task (ST), or watching a documentary TV show about the Olympic Games (CON). Then, the athletes ran the simulated race (i.e. the 100 and 200-m dash). There was no condition ( > 0.05) or time effect ( > 0.05) for MPV, CMJ, 100-m, or 200-m dash performance. In conclusion, the present study results revealed no mental fatigue effect induced by SMA or ST on neuromuscular, 100-m or 200-m dash performance in male college sprinters.
本研究旨在分析心理疲劳对大学生短跑运动员平均推进速度（MPV）、反跳（CMJ）、100 米和 200 米短跑成绩的影响。共有 16 名短跑项目（100 米和 200 米）的男性运动员参加了这项研究。每位参与者都进行了两次基线访问，然后在三种实验条件下进行跑步。评估（MPV 和 CMJ）分别在智能手机使用（SMA）或斯特鲁普任务（ST）或观看有关奥运会的纪录片电视节目（CON）前后进行。然后，运动员进行模拟比赛（即 100 米和 200 米短跑）。在 MPV、CMJ、100 米或 200 米短跑成绩方面，没有条件（ > 0.05）或时间效应（ > 0.05）。总之，本研究结果表明，SMA 或 ST 引起的心理疲劳不会对男性大学生短跑运动员的神经肌肉、100 米或 200 米短跑成绩产生影响。
