Abstract

Perceived effort for goal-directed reaching may be impacted by the level of self-reported fatigue, however, the relationship between self-reported fatigue and perceived effort has not been examined. We examined how perceived effort changed under varied reach conditions and the relationship between fatigue, perceived effort and reach performance. Twenty-three young adults performed reach actions toward 9 different targets on a digitizing tablet. Perceived effort was measured using the Borg Rate of Perceived Exertion and Paas Mental Effort Rating Scale. Self-reported fatigue was quantified using the Fatigue Scales for Motor and Cognitive Functions. As reach conditions became more difficult, perceived effort increased significantly. Further, individuals who reported greater fatigue also reported greater perceived effort and showed greater endpoint error during reaching.

摘要

实现目标导向的感知努力可能会受到自我报告疲劳水平的影响，但是，自我报告疲劳与感知努力之间的关系尚未得到检验。我们研究了感知努力在不同到达条件下的变化以及疲劳、感知努力和到达性能之间的关系。23 名年轻人在数字化平板电脑上针对 9 个不同的目标执行伸手动作。使用 Borg Rate of Perceived Exertion 和 Paas Mental Effort Rating Scale 测量感知努力。使用运动和认知功能的疲劳量表量化自我报告的疲劳。随着到达条件变得更加困难，感知到的努力显着增加。更远，
