ABSTRACT

Background and Objectives of the article

Loss aversion bias, whereby losses loom larger than gains, can be reduced by stress. At the same time, vigorous physical exercise is a powerful neuroendocrine stressor and heart rate variability (HRV) provides an objective measure of the actual exercise impact, relative to each individual physical condition. Our aim was to study whether vigorous exercise can influence loss aversion, considering HRV in this relation. We hypothesized that the lower HRV derived from vigorous exercise (i.e., when stressor produced the most impact) would predict a lower loss aversion.

Methods

Two groups (Experimental, N = 37; Control, N = 39) completed a loss aversion task, but the experimental group was exposed to an acute physical stressor before.

Results

Results revealed a significant group x HRV interaction. In the control group, HRV was not associated with loss aversion. Conversely, as hypothesized, the lower HRV levels derived from exercise were associated with a lesser loss aversion in the experimental group.

Conclusions

Results suggest that physiological changes from physical exercise could affect decision-making by reducing loss aversion.

剧烈体育锻炼后的心率变异性与损失厌恶呈正相关

摘要

文章的背景和目的

损失厌恶偏差，即损失比收益更大，可以通过压力减少。同时，剧烈的体育锻炼是一种强大的神经内分泌压力源，心率变异性 (HRV) 提供了实际锻炼影响的客观衡量标准，相对于每个个体的身体状况。我们的目的是研究剧烈运动是否会影响损失厌恶，考虑到这种关系中的 HRV。我们假设来自剧烈运动（即压力源产生最大影响时）的较低 HRV 会预测较低的损失厌恶。

方法

两组（实验组，N  = 37；对照组，N  = 39）完成了损失厌恶任务，但实验组之前暴露于急性身体压力源。

结果

结果显示显着的组 x HRV 相互作用。在对照组中，HRV 与损失厌恶无关。相反，正如假设的那样，来自运动的较低 HRV 水平与实验组中较少的损失厌恶相关。

结论

结果表明，体育锻炼带来的生理变化可以通过减少损失厌恶来影响决策。
