Abstract

Both acute aerobic (AE) and resistance exercise (RE) have been acknowledged to be effective methods in enhancing executive function and brain-related P3 amplitudes. Nevertheless, the effect of acute concurrent exercise training (CET), combining both AE and RE, on executive function remains subject to speculation. Moreover, investigation of the mechanisms that underlie improvements in executive function would facilitate scientific understanding. Notably, lactate has emerged as a candidate among several potential mechanisms. Therefore, the main aim of the present study was to investigate the effect of acute CET on the cognitive flexibility dimension of executive function using behavioural and neuro-electric measures. A secondary aim was to determine the mediating effect of blood lactate in the acute exercise–executive function relationship. Seventy-eight young adults (38 women, 40 men; 22.8 ± 1.8 years) were randomly assigned to one of the following groups: CET, AE, or reading control (RC). Cognitive flexibility was evaluated using the Task-Switching Test and its derived electroencephalography (EEG) was assessed immediately prior to and following each treatment. Fingertip lactate assays were taken prior to, at the midpoint, and after each treatment. Both acute CET and AE shortened response time regardless of test conditions when compared to the RC group. Greater P3 amplitude was observed following CET in the heterogeneous condition and under AE in the switch condition. A significant mediation of blood lactate for response time emerged in both the CET and AE groups for the heterogeneous and switch conditions. The blood lactate mediation was not reflected in P3 amplitude. The present findings suggest that acute CET leads to positive behavioural and neuro-electric alterations of cognitive flexibility, and its effect is similar to AE. Additionally, blood lactate serves as a mediator of the effects of acute exercise on executive function from a behavioural, but not neuro-electric standpoint.

急性并发运动训练的影响及乳酸对执行功能的中介作用：一项ERP研究。

急性有氧运动（AE）和阻力运动（RE）都被认为是增强执行功能和大脑相关P3振幅的有效方法。然而，急性并发运动训练（CET）结合AE和RE对执行功能的影响仍有待猜测。此外，对改善执行职能的机制进行调查将有助于科学理解。值得注意的是，乳酸已经成为几种潜在机制中的一种候选。因此，本研究的主要目的是通过行为和神经电测量来研究急性CET对执行功能认知灵活性维度的影响。第二个目的是确定血液乳酸在急性运动执行功能关系中的中介作用。78名年轻人（38名女性，40名男性；22.8±1.8岁）被随机分配到以下组之一：CET、AE或阅读对照组（RC）。使用任务转换测试评估认知灵活性，并在每次治疗前后立即评估其衍生脑电图（EEG）。在每次治疗之前、中期和之后进行指尖乳酸测定。与RC组相比，无论测试条件如何，急性CET和AE都缩短了反应时间。在非均匀条件下CET之后和在切换条件下AE之后观察到更大的P3振幅。对于异质性和转换条件，CET组和AE组的血乳酸对反应时间都有显著的调节作用。血乳酸介导没有反映在P3振幅上。目前的研究结果表明，急性CET会导致认知灵活性的积极行为和神经电改变，其影响与AE相似。此外，从行为而非神经电的角度来看，血乳酸是急性运动对执行功能影响的媒介。

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.
