The Effect of Mental Fatigue on Upper Extremity Functional Performance

2026年6月12日 更新者：Gürsu Sayar、Izmir Bakircay University
Mental fatigue (MF) is known to impair cognitive performance and may negatively affect physical performance. 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.

参加者グループ / アーム
介入・治療
実験的：Mental Fatigue Condition
Participants in this arm completed a mental fatigue induction protocol involving a prolonged and cognitively demanding Stroop task designed to induce sustained inhibitory control and attentional effort. The task was performed for an extended duration to elicit subjective mental fatigue. Pre- and post-condition assessments of upper-extremity physical performance, cognitive performance, motivation, perceived exertion, and subjective mental fatigue were conducted.
行動：精神疲労
精神的疲労（MF）は、長時間または激しい認知活動の後に生じる、疲労感やパフォーマンスの低下を特徴とする心理生物学的状態です。
介入なし：Control condition
Participants in this arm watched a neutral, emotionally non-arousing documentary for an equivalent duration as the mental fatigue condition. This activity was designed to minimize cognitive load and avoid inducing mental fatigue. Pre- and post-condition assessments of upper-extremity physical performance, cognitive performance, motivation, perceived exertion, and subjective mental fatigue were conducted.

主要な結果の測定

結果測定
メジャーの説明
時間枠
Reactive Upper Quarter Y Balance Test
時間枠：Pre-intervention and immediately post-intervention (each experimental and control condition session)
Measures visuomotor reaction time, reaching accuracy, and balance errors during a reactive upper quarter Y balance test performed under visual stimuli conditions.
Pre-intervention and immediately post-intervention (each experimental and control condition session)
Closed Kinetic Chain Upper Extremity Stability Test
時間枠：Pre-intervention and immediately post-intervention (each session)
Assesses upper-extremity muscular endurance and stability by counting the number of alternating hand touches performed in a 15-second push-up position task.
Pre-intervention and immediately post-intervention (each session)
Upper Quarter Y Balance Test
時間枠：Pre-intervention and immediately post-intervention (each session)
Evaluates dynamic upper-extremity reach performance and composite score based on normalized reach distances in three directions.
Pre-intervention and immediately post-intervention (each session)
Seated Single-Arm Shot Put Test
時間枠：Pre-intervention and immediately post-intervention (each session)
Measures upper-extremity explosive power based on throwing distance of a 6-lb medicine ball.
Pre-intervention and immediately post-intervention (each session)

二次結果の測定

結果測定
メジャーの説明
時間枠
Subjective Mental Fatigue
時間枠：Baseline, every 5 minutes during intervention, and post-intervention (each session)
Subjective Mental Fatigue measured using the Mental Visual Analog Scale (M-VAS). The scale ranges from 0 to 100, where 0 indicates no mental fatigue and 100 indicates the highest level of mental fatigue imaginable. Higher scores indicate worse mental fatigue.
Baseline, every 5 minutes during intervention, and post-intervention (each session)
Go/No-Go Task
時間枠：Immediately post-intervention (each session)
Assesses executive function using a computerized Go/No-Go task. Outcomes include reaction time (milliseconds) and response accuracy (percentage of correct responses, ranging from 0% to 100%). Higher accuracy indicates better executive function performance, while shorter reaction times indicate better performance.
Immediately post-intervention (each session)
Motivation State
時間枠：Pre- and post-intervention (each session)
Assesses task-related motivation using the Assessment of Motivational States in Performance Environments questionnaire. The questionnaire includes two 7-item subscales: Interest Motivation and Success Motivation. Higher scores indicate greater task engagement, interest in the task, and motivation to perform successfully.
Pre- and post-intervention (each session)
Perceived Exertion
時間枠：Immediately after physical performance testing (each session)
Assesses perceived exertion using the Borg Rating of Perceived Exertion Scale. Scores range from 6 to 20, with higher scores indicating greater perceived exertion.
Immediately after physical performance testing (each session)
Stroop Task Performance
時間枠：During intervention (continuous, averaged per block)
Assesses cognitive performance using a computerized Stroop task. Outcomes include reaction time (milliseconds) and response accuracy (percentage of correct responses, ranging from 0% to 100%). Higher accuracy and shorter reaction times indicate better cognitive performance.
During intervention (continuous, averaged per block)
