Abstract

BackgroundThis study aimed to investigate the neural mechanisms that differentiate mind–body practices from aerobic physical activities and elucidate their effects on cognition and healthy aging. We examined functional brain connectivity in older adults (age > 60) without pre-existing uncontrolled chronic diseases, comparing Tai Chi with Water Aerobics practitioners.MethodsWe conducted a cross-sectional, case–control fMRI study involving two strictly matched groups (n = 32) based on gender, age, education, and years of practice. Seed-to-voxel analysis was performed using the Salience, and Frontoparietal Networks as seed regions in Stroop Word-Color and N-Back tasks and Resting State.ResultsDuring Resting State condition and using Salience network as a seed, Tai Chi group exhibited a stronger correlation between Anterior Cingulate Cortex and Insular Cortex areas (regions related to interoceptive awareness, cognitive control and motor organization of subjective aspects of experience). In N-Back task and using Salience network as seed, Tai Chi group showed increased correlation between Left Supramarginal Gyrus and various cerebellar regions (related to memory, attention, cognitive processing, sensorimotor control and cognitive flexibility). In Stroop task, using Salience network as seed, Tai Chi group showed enhanced correlation between Left Rostral Prefrontal Cortex and Right Occipital Pole, and Right Lateral Occipital Cortex (areas associated with sustained attention, prospective memory, mediate attention between external stimuli and internal intention). Additionally, in Stroop task, using Frontoparietal network as seed, Water Aerobics group exhibited a stronger correlation between Left Posterior Parietal Lobe (specialized in word meaning, representing motor actions, motor planning directed to objects, and general perception) and different cerebellar regions (linked to object mirroring).ConclusionOur study provides evidence of differences in functional connectivity between older adults who have received training in a mind–body practice (Tai Chi) or in an aerobic physical activity (Water Aerobics) when performing attentional and working memory tasks, as well as during resting state.

练习太极拳和水上有氧运动的老年人大脑连通性的差异：一项病例对照研究

背景本研究旨在调查心身练习与有氧体育活动之间的神经机制差异，并阐明它们对认知和健康老龄化的影响。我们将太极拳练习者与水上有氧运动练习者进行了比较，研究了未患有未控制慢性疾病的老年人（年龄为 60 岁）的大脑功能连通性。方法我们进行了一项横断面病例对照 fMRI 研究，研究涉及两组严格匹配的人群（n = 32），这两组的性别、年龄、教育程度和练习年限均相同。结果在静息状态条件下，以 "愉悦 "网络为种子区域，太极拳组在前扣带回皮层和岛叶皮层区域（与感知觉、认知控制和主观体验的运动组织有关的区域）之间表现出更强的相关性。在 "N-Back "任务中，太极组以 "体验网络 "为种子，显示左侧边上回与小脑各区域（与记忆、注意力、认知处理、感觉运动控制和认知灵活性有关）之间的相关性增强。在以 "显著性网络 "为种子的 Stroop 任务中，太极组显示出左侧梭状前额叶皮层与右侧枕极和右侧枕外侧皮层之间的相关性增强（这些区域与持续注意、前瞻性记忆、外部刺激与内部意向之间的中介注意有关）。此外，在以前顶叶网络为种子的 Stroop 任务中，水上有氧运动组在左后顶叶（专门从事词义、代表运动动作、针对物体的运动规划和一般感知）和不同小脑区域（与物体镜像有关）之间表现出更强的相关性。结论：我们的研究提供的证据表明，接受过身心练习（太极）或有氧体育活动（水中有氧操）训练的老年人在执行注意力和工作记忆任务时以及在休息状态下的功能连接存在差异。

期刊介绍： Frontiers in Integrative Neuroscience publishes rigorously peer-reviewed research that synthesizes multiple facets of brain structure and function, to better understand how multiple diverse functions are integrated to produce complex behaviors. Led by an outstanding Editorial Board of international experts, this multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide. Our goal is to publish research related to furthering the understanding of the integrative mechanisms underlying brain functioning across one or more interacting levels of neural organization. In most real life experiences, sensory inputs from several modalities converge and interact in a manner that influences perception and actions generating purposeful and social behaviors. The journal is therefore focused on the primary questions of how multiple sensory, cognitive and emotional processes merge to produce coordinated complex behavior. It is questions such as this that cannot be answered at a single level – an ion channel, a neuron or a synapse – that we wish to focus on. In Frontiers in Integrative Neuroscience we welcome in vitro or in vivo investigations across the molecular, cellular, and systems and behavioral level. Research in any species and at any stage of development and aging that are focused at understanding integration mechanisms underlying emergent properties of the brain and behavior are welcome.
