目的:探究脑力疲劳(MF)对足球运动员的30-15间歇跑(30-15IFT)测试的有氧耐力表现的影响。方法:采用随机交叉对照实验,22名男子业余足球运动员以随机、平衡的顺序执行间隔≥48 h、时长为45 min的Stroop任务(MF诱导,实验组)和观看情绪中性视频任务(对照处理,对照组),受试者执行每次任务后参加30-15IFT测试进行有氧耐力表现评估。主要记录受试者在执行任务前后的脑力疲劳分数(VAS-MF)、动机(VAS-MO)、布鲁奈尔疲劳分数(BRUMS-F)、布鲁奈尔活力分数(BRUMS-V),执行任务过程中的平均心率(HRave),执行任务后的大脑努力分数(VAS-ME),以及30-15IFT测试过程中的主观疲劳度(RPE)、平均心率(HRave)和峰值心率(HRpeak),使用重复测量方差分析和配对样本t检验对数据进行统计学分析。结果:实验组在执行任务前的各项指标与对照组无显著差异(均为p>0.05),执行任务过程中的HRave(p=0.031),执行任务后的VAS-MF(p<0.001)、VAS-ME(p<0.001)和BRUMS-F(p=0.006)均与对照组有显著差异;实验组的30-15IFT有氧耐力表现测试的力竭时间、力竭速度和最大摄氧量均显著低于对照组(力竭时间:p=0.034;力竭速度:p=0.03;最大摄氧量:p=0.029);实验组在30-15IFT测试前的动机水平与对照组无显著差异;脑力疲劳诱导时间影响心率、主观疲劳度的主效应显著;脑力疲劳干预方式影响主观疲劳度的主效应显著;实验组和对照组的主观疲劳度均随脑力疲劳诱导时间延长而增强(p<0.001)。结论:MF会使男子业余足球运动员的30-15IFT测试的有氧耐力表现水平降低。

Objective: This study aims to investigate the effect of mental fatigue (MF) on football players’aerobic endurance performance in 30-15 intermittent fitness test (30-15 IFT). Methods:A randomized crossover controlled trial was employed. Twenty-two male amateur football players participated in a 45 min Stroop task (MF induction, experimental group) and emotionally neutral video viewing (control treatment, control group) in randomly, counter-balanced order with washout period ≥48 h. After each task, participants performed 30-15 IFT test for aerobic endurance performance assessment. The primary recorded data includes visual analogue scale for mental fatigue (VAS-MF) and motivation (VAS-MO), Brunel Mood Scale Fatigue (BRUMS-F)and Brunel Mood Scale Vigor (BRUMS-V) before and after the task, average heart rate(HRave)during the task, visual analogue scale for mental exertion (VAS-ME) after the task, as well as rating of perceived exertion(RPE), HRave, and peak heart rate (HRpeak) during the 30-15IFT test. Statistical analysis was mainly conducted using paired-sample t-tests and repeated measures ANOVA. Results:No significant between-group differences were observed in any baseline measures prior to task execution(all p> 0.05). During the task, the EG showed significantly different HRave values(p=0.031). Post-task assessments revealed significant differences in VAS-MF(p< 0.001), VAS-ME (p< 0.001), and BRUMS-F (p=0.027).The EG demonstrated significantly lower exhaustion time, exhaustion speed, and maximal oxygen uptake in the 30-15IFT compared to CG (TTE:p=0.034;VIFT:p=0.03;Vmax(O2):p=0.029). There was no significant difference in motivation level between EG and CG before 30-15IFT. The main effect of mental fatigue induction time was significant on both heart rate and RPE. Additionally, the main effect of mental fatigue intervention type significantly influenced RPE. Both EG and CG exhibited an increase in RPE as mental fatigue induction time prolonged (p< 0.001). Conclusion:MF impairs aerobic endurance performance of 30-15IFT in male amateur football players.
