There is strong evidence that regular physical activity reduces risk of cardiovascular disease. Building on the evidence review for the 2008 Physical Activity Guidelines for Americans, this article summarizes the recommended amounts and types of physical activity for the primary prevention of cardiovascular disease in older adults. Key guidelines are largely based on current understanding of the dose-response relationship between amount of physical activity and risk of chronic disease. In part due to the preventive effects on cardiovascular disease, physical activity has beneficial effects on functional limitations and health-related quality of life in older adults. Gaps in research on physical activity and cardiovascular health are discussed, with an emphasis on the need for research on how sedentary time affects risk of cardiovascular disease and other chronic illnesses.
有强有力的证据表明，有规律的身体活动可降低心血管疾病的风险。本文以《2008 年美国人身体活动指南》的证据审查为基础，总结了推荐的老年人进行心血管疾病一级预防的身体活动量和类型。主要指南主要基于对身体活动量与慢性病风险之间的剂量-反应关系的当前理解。部分由于对心血管疾病的预防作用，身体活动对老年人的功能限制和健康相关生活质量有有益影响。讨论了身体活动与心血管健康方面的研究差距，并强调需要研究久坐时间如何影响心血管疾病和其他慢性病的风险。
