AbstractObjective： This study aims to investigate the effectof mental fatigue （MF）on fotballplayers'aerobicendurance performancein 3O-15 intermittent fitness test（ 30-15IFT） .Methods：A randomized crossover controlled trial was employed. Twenty-two male amateur football players participated in a 45min Stroop task

（MFinduction，experimental group）and emotionallyneutral video viewing （control treatment，control group）in randomly， counter-balanced order with washout period ⩾48h . After each task， participants performed 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 MoodScaleVigor （BRUMS-V）beforeandafterthe task，averageheartrate（ HRave ）duringthe task，visual analogue scale for mental exertion （VAS-ME） after the task，as wellas ratingof perceived exertion（RPE）， HRave and peak heart rate（ MRpeak ） during the 3O-15IFr test.Statistical analysis was mainly conducted using paired-sample t-tests and repeated measures ANOVA.Results：No significant between-group diffrences were observed in any baseline measures prior to task execution （all p>0.05 ）.During the task，theEG showed significantly different HRave values（ p =0.031）.Post-task assessmentsrevealed significant differencesin VAS-MF （p<0.001 ） VAS-ME （ p<0.001 ），andBRUMS-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=O.034; VIFT： P =0.03; （20 Vmax（02）：p =0.029）.There was no significant difference in motivation level between EG and CG before 30-15IFr. The main efectof mental fatigue induction time was significant onboth heartrateandRPE.Additionaly，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 30-15⋅IFT in male amateur football players.
