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.

研究目的本研究探讨了急性有氧运动对甲基苯丙胺使用障碍（MUD）患者情绪记忆的编码和巩固过程的影响：两项实验均采用受试内交叉设计。在实验 1 中，32 名参与者在完成学习任务前进行了 30 分钟的中高强度（预测最大心率的 70%-80% ）有氧运动和一项静坐任务。间隔 50 分钟后，参与者完成一项识别任务。在实验 2 中，36 名参与者首先完成了学习任务，然后进行了 30 分钟的中高强度有氧运动或静坐任务。经过 20 分钟的间歇后，参与者开始进行识别任务。识别任务主要评估参与者识别新旧图像的准确性、识别判断的反应时间以及信心评级：实验 1 中，有氧运动条件下的参与者对中性情绪图像的辨别指数 d' 明显高于静坐条件下的参与者。此外，他们对正面和中性情绪图像的反应偏差指数β也明显较低。此外，与久坐不动的人相比，有氧运动条件下的参与者对与 METH 相关的图像和负面图像的反应时间都明显更长。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 和反应时间均无明显差异：本研究揭示了急性有氧运动对 MUD 患者情绪记忆特定阶段的显著影响，尤其是在增强编码能力方面。作为一种非药物干预措施，运动具有缓解成瘾相关认知缺陷和降低复发风险的潜力。这项研究进一步支持了将体育锻炼纳入药物使用障碍治疗的前景，强调了体育锻炼在促进认知功能恢复和整体治疗效果方面的关键作用。

期刊介绍： Psychology of Sport and Exercise is an international forum for scholarly reports in the psychology of sport and exercise, broadly defined. The journal is open to the use of diverse methodological approaches. Manuscripts that will be considered for publication will present results from high quality empirical research, systematic reviews, meta-analyses, commentaries concerning already published PSE papers or topics of general interest for PSE readers, protocol papers for trials, and reports of professional practice (which will need to demonstrate academic rigour and go beyond mere description). The CONSORT guidelines consort-statement need to be followed for protocol papers for trials; authors should present a flow diagramme and attach with their cover letter the CONSORT checklist. For meta-analysis, the PRISMA prisma-statement guidelines should be followed; authors should present a flow diagramme and attach with their cover letter the PRISMA checklist. For systematic reviews it is recommended that the PRISMA guidelines are followed, although it is not compulsory. Authors interested in submitting replications of published studies need to contact the Editors-in-Chief before they start their replication. We are not interested in manuscripts that aim to test the psychometric properties of an existing scale from English to another language, unless new validation methods are used which address previously unanswered research questions.
