While its effects on lower-extremity functional performance have been investigated, little is known about the influence of MF on upper-extremity physical performance tests commonly used in sports and rehabilitation settings. This randomized crossover study will investigate the effects of experimentally induced mental fatigue on upper-extremity physical performance in 16 healthy physically active adults. Participants will complete both a mental fatigue condition, involving a prolonged Stroop task, and a control condition consisting of watching an emotionally neutral documentary. Before and after each condition, participants will perform the Upper Quarter Y Balance Test, Reactive Upper Quarter Y Balance Test, Closed Kinetic Chain Upper Extremity Stability Test, and Seated Single-Arm Shot Put Test. Subjective mental fatigue, cognitive performance, motivation, and perceived exertion will also be assessed. The findings will improve understanding of whether mental fatigue influences upper-extremity physical performance test outcomes and may assist clinicians and researchers in interpreting these assessments in sports medicine and rehabilitation contexts.",[22],[22,80,81,82,83,84,85,86],"Upper Extremity","Physical Performance","Functional Testing","Sports Medicine","Cognitive Performance","Visuomotor Reaction Time","Upper Quarter Y Balance Test","NOT_YET_RECRUITING","2026-06-12",{"date":90,"type":91},"2026-06-15","ACTUAL",{"date":93,"type":73},"2026-07-01",{"date":95,"type":73},"2026-12-01",{"name":5,"class":6},1]
