【摘要】 久坐是一种在保持清醒状态下能量消耗较低的行为，同时也是心血管疾病的主要致病因素之一。久坐时由于代谢需求和骨骼肌活动的减少，使久坐个体的血流量减少、流体静压力增加、肌肉泵作用，以及对血糖、血脂的调节能力下降，进而损害心血管功能，这会增加心血管疾病的风险。久坐间断是预防和改善久坐危害的有效途径之一，不同的间断频率、强度、时间及类型会带来不同的效果。本文采用文献资料法、逻辑分析法等研究方法，通过梳理和综述久坐行为对心血管健康的影响，探讨其潜在的生物学机制，并评估久坐间断策略在预防和改善心血管疾病风险中的有效性，以期为未来有关久坐与心血管疾病的研究提供科学参考。更多还原

【Abstract】 Prolonged sitting, characterized by low energy expenditure while in a wakeful state, is a major contributing factor to cardiovascular diseases. During prolonged sitting, reduced metabolic demands and decreased skeletal muscle activity lead to diminished blood flow, increased hydrostatic pressure, impaired muscle pump action, and reduced regulation of blood sugar and lipids, ultimately damaging cardiovascular function and increasing the risk of cardiovascular diseases. Interrupting prolonged sitting is an effective approach to prevent and mitigate these hazards. Different interruption frequencies, intensities, durations, and types yield varying effects. This article employs research methods such as literature review and logical analysis to review the impact of prolonged sitting on cardiovascular health, explore its potential biological mechanisms, and evaluate the effectiveness of interrupting prolonged sitting in preventing and mitigating the risk of cardiovascular diseases. The aim is to provide a scientific reference for future research on the association between prolonged sitting and cardiovascular diseases.更多还原
