Abstract: Interoception is generally defined as the processing that perceives, integrates, and interprets signals from various viscera. In recent years, the relationship between physical activity and interoception has received considerable attention. Changes in interoception help individuals to monitor multimodal signals in terms of physical activity, modulate exercise intensity, and influence emotional experience. In addition, physical activity also influences the onset of interoception, on the one hand by altering the afferents of physiological signals to achieve bottom-up regulation, and on the other hand physical activity is also influenced by attention, which regulates perceptual processes in a top-down manner. This paper summarizes the potential physiological mechanism of the interaction between physical activity and interoception, and refines the theoretical model of bidirectional physical activity - interoception loop. Optimizing the interoceptive ability of healthy people through appropriate interventions including physical activity, and repairing the interoceptive function of interoceptively impaired patients are beneficial to their health behavior and disease management. Future research should further deepen the theoretical mechanisms and develop physical activity-based interventions to optimise individuals’ interoception, taking into account influences such as individual differences.

摘要： 内感受通常被定义为感知、整合和解释各内脏信号的加工过程。近年来，身体活动和内感受关系的研究备受关注。内感受的变化有助于个体监控身体活动方面的多模态信号，调节运动强度，影响情绪体验。此外，身体活动也会影响内感受的发生，一方面，通过改变生理信号的传入实现自下而上的调节，另一方面，身体活动也会受到注意的影响，通过自上而下的方式调节内感受的感知过程。本文总结了身体活动和内感受交互作用的生理机制，并提炼了身体活动-内感受双向交互的理论模型。通过包含身体活动的适当干预手段优化健康人群的内感受能力，并对内感受受损的患者进行内感受功能修复，有利于其健康行为和疾病管理。未来研究应进一步深化理论机制，并结合个体差异等影响因素，开发以体育活动为基础的干预措施来优化个体的内感受。
