摘　　要：目的通过试验研究姿态控制能力和紧张状态下累积性疲劳的关系并探究疲劳的快速检测方法。方法招募上海理工大学15名参加全国大学生电子设计竞赛的本科生,分别评估其在疲劳和清醒状态下的姿态控制能力。受试者需要完成主观疲劳、睡眠时长问卷,双足静立移动螺旋测试的动态平衡和睁眼、闭眼条件下的静态平衡测试。采用Wilcoxon符号秩检验对数据进行统计分析。结果主观问卷和睡眠时长统计结果表明受试者在比赛期间疲劳程度不断加深。平衡能力测试结果表明通过第3次的累积性疲劳测试与第4次清醒状态测试比较,螺旋轨迹准确率(Z=2.329,P=0.020)、睁眼轨迹总长度(Z=2.272,P=0.023)、闭眼轨迹总长度(Z=2.045,P=0.041)和闭眼包络面积(Z=2.329,P=0.020)差异均具有统计学意义。结论姿态控制能力和疲劳存在联系。螺旋轨迹准确率、睁眼轨迹总长度、闭眼轨迹总长度和闭眼包络面积可作为疲劳状态快速评估的有效手段。Objective To study the relationships between postural control ability and cumulative fatigue under stress and to explore rapid methods for assessing fatigue.Methods Fifteen undergraduates from Shanghai University of Science and Technology who participated in the National Undergraduate Electronics Design Competition were enrolled to evaluate their postural control capabilities under fatigue and alertness.Participants were required to complete questionnaires assessing subjective fatigue and sleep duration and undergo dynamic balance tests and static balance tests on a balance testing device under both open-eye and closed-eye conditions.Statistical analysis was conducted using the Wilcoxon Signed-Rank Test.Results Data from subjective questionnaires and on sleep duration revealed a continuous increase in fatigue levels among subjects throughout the competition,indicating the cumulative nature of fatigue.The results of the balance ability assessments revealed statistically significant differences in such key metrics as the spiral trajectory accuracy(Z=2.329,P=0.020),total length of open-eye trajectory(Z=2.272,P=0.023),total length of closed-eye trajectory(Z=2.045,P=0.041),and closed-eye envelope area(Z=2.329,P=0.020).Conclusion There is a significant correlation between postural control ability and fatigue.The related metrics have demonstrated their utility as effective indicators for rapid assessment of fatigue status.
