Abstract

The aim of the present research is to test whether resilience in a motor task enhances or diminishes when encountering stressors. We conducted a lateral movement task during which we induced stressors and tracked the movement accuracy of each participant over time. Stressors corresponded to organismic constraints (i.e., visual occlusion), task constraints (i.e., movement sensitivity), or both types of constraints in an alternating pattern. In order to determine resilience, we introduced a measure combining the strength of a stressor and the relaxation time. Across the three conditions, we found that resilience was enhanced rather than diminished over time. This supports the notion that stressors in the form of constraint alterations can be beneficial to human motor performance.

摘要

本研究的目的是测试在遇到压力源时，运动任务的弹性是增强还是减弱。我们进行了横向运动任务，在此期间我们诱发了压力源并随着时间的推移跟踪每个参与者的运动准确性。压力源对应于有机体约束（即视觉遮挡）、任务约束（即运动敏感性）或交替模式中的两种类型的约束。为了确定弹性，我们引入了一种结合压力源强度和放松时间的方法。在这三种情况下，我们发现弹性随着时间的推移而增强而不是减弱。这支持了约束改变形式的压力源可以有益于人类运动表现的观点。
