Abstract

OBJECTIVE

This study investigates the effects of acute aerobic exercise on the encoding and consolidation processes of emotional memory in individuals with methamphetamine use disorder (MUD).

METHODS

A within-subject cross-over design was utilized for both experiments. In Experiment 1, thirty-two participants engaged in 30 min of moderate-to-high intensity (70 %-80 % of predicted HRmax) aerobic exercise and a sedentary task before completing a learning task. Following a 50-min interval, participants completed a recognition task. In Experiment 2, thirty-six participants first completed the learning task, then engaged in a 30-min session of moderate-to-high intensity aerobic exercise or a sedentary task. After a 20-min interval, participants undertook the recognition task. The recognition task assessed participants' accuracy in identifying old and new images, reaction times for recognition judgments, and confidence ratings.

RESULTS

In Experiment 1, participants in the aerobic exercise condition exhibited significantly higher discrimination index d' for neutral emotion images compared to those in the sedentary condition. Additionally, they demonstrated a significantly lower response bias index β for positive and neutral emotion images. Furthermore, participants in the aerobic exercise condition displayed significantly longer reaction times for both METH-related and negative images compared to those in the sedentary condition. In Experiment 2, no significant differences were observed in discrimination index d', response bias index β, and reaction times between the two task conditions.

CONCLUSION

This study reveals a significant impact of acute aerobic exercise on specific phases of emotional memory in individuals with MUD, particularly in enhancing encoding abilities. As a non-pharmacological intervention, exercise demonstrates the potential to alleviate addiction-related cognitive deficits and reduce the risk of relapse. The research further supports the prospect of integrating physical exercise into the treatment of substance use disorders, highlighting its critical role in promoting cognitive function recovery and overall therapeutic outcomes.

摘要

目的

本研究调查急性有氧运动对甲基苯丙胺使用障碍(MUD)个体情绪记忆的编码和巩固过程的影响。

方法

两个实验均采用受试者内交叉设计。在实验1中,32名参与者在完成学习任务前进行30分钟的中高强度(预测心率最大值的70%-80%)有氧运动和一项久坐任务。经过50分钟的间隔后,参与者完成识别任务。在实验2中,36名参与者首先完成学习任务,然后进行30分钟的中高强度有氧运动或久坐任务。经过20分钟的间隔后,参与者进行识别任务。识别任务评估参与者识别新旧图像的准确性、识别判断的反应时间和信心评级。

结果

在实验1中,与久坐组相比,有氧运动组参与者对中性情绪图像的辨别指数d'显著更高。此外,他们对积极和中性情绪图像的反应偏差指数β显著更低。此外,与久坐组相比,有氧运动组参与者对甲基苯丙胺相关图像和负面图像的反应时间显著更长。在实验2中,两种任务条件下的辨别指数d'、反应偏差指数β和反应时间均未观察到显著差异。

结论

本研究揭示了急性有氧运动对MUD个体情绪记忆特定阶段有显著影响,尤其是在增强编码能力方面。作为一种非药物干预措施,运动显示出缓解成瘾相关认知缺陷和降低复发风险的潜力。该研究进一步支持了将体育锻炼纳入物质使用障碍治疗的前景,突出了其在促进认知功能恢复和整体治疗效果方面的关键作用。
