Compromised attentional resources during perceived fatigue has been suggested to alter motor control. The authors determined if measures of postural control and gait are predicted by state and trait physical and mental fatigue and energy, and how these relationships are modified by sex, sleep quality, and physical activity. Young adults (n = 119) completed the Modified Clinical Test of Sensory Integration, overground walking, and questionnaires to quantify fatigue and energy, sleep quality, and physical activity. Regression models indicated that trait fatigue, trait energy, and sleep quality were predictors of postural control (p ≤ .02, R² ≥ .04). State fatigue, state energy, and sex were predictors of gait (p ≤ .05, R² ≥ .03). While the variance explained was low (3–13%), the results demonstrate perceptions of fatigue and energy may influence posture and gait.

已建议在感知疲劳期间受损的注意力资源会改变运动控制。作者确定了姿势控制和步态的测量是否可以通过身体和精神疲劳和精力的状态和特征来预测，以及这些关系如何被性别、睡眠质量和身体活动所改变。年轻成人 ( n  = 119) 完成了改良的感觉统合临床测试、地上行走和量化疲劳和能量、睡眠质量和身体活动的问卷。回归模型表明，特质疲劳、特质能量和睡眠质量是姿势控制的预测因素（p  ≤ .02，R ²  ≥ .04）。状态疲劳、状态能量和性别是步态的预测因子 ( p  ≤ .05,R ²  ≥ .03)。虽然解释的方差很低（3-13%），但结果表明对疲劳和能量的感知可能会影响姿势和步态。
