> There is nothing better than exercise but more exercise. Regular physical activity (PA) and high cardiorespiratory fitness (CRF: aerobic capacity, VO2 max) reduce all-cause mortality even after adjusting for relevant confounders.1 2 Large-scale studies indicate an almost linear relationship between increasing CRF and longevity, with no signs of an upper limit.3 It remains less clear which PA volumes are optimal for a long life. Public health guidelines recommend a minimum of 150–300 min moderate intensity aerobic PA or 75–150 min vigorous intensity aerobic PA per week to induce general health benefits.4 Dr Hannah Arem and colleagues, using pooled data from six studies in the USA and Europe (including 661 137 adults), showed that meeting PA guidelines was associated with a large longevity benefit.5 And there were even further improvements until the benefit for longevity reached a threshold at a level 3–5 times higher (450–750 min/week) than the minimum recommendations, without adverse effects in those performing PA at ≥10 times that minimum. The maximum all-cause mortality reduction was almost 40% without relevant differences between …

为您的生活而奔跑：调整每周的体力活动量以延长寿命

> 没有什么比锻炼更好的了，只有更多的锻炼。即使在调整了相关混杂因素后，规律的身体活动 (PA) 和高心肺适能（CRF：有氧能力，最大摄氧量）也能降低全因死亡率。1 2 大规模研究表明，增加 CRF 与寿命之间几乎呈线性关系，没有上限的迹象。3 目前尚不清楚哪些 PA 体积最适合长寿命。公共卫生指南建议每周至少进行 150–300 分钟中等强度有氧运动或 75–150 分钟剧烈强度有氧运动，以促进整体健康。4 Hannah Arem 博士及其同事使用来自美国和欧洲的六项研究的汇总数据（包括 661 137 名成人），表明满足 PA 指南与较大的长寿益处相关。5 甚至还有进一步的改进，直到长寿益处达到比最低建议高 3-5 倍（450-750 分钟/周）的阈值，而对那些执行 PA ≥ 10 倍的最低建议没有不利影响。最大全因死亡率降低了近 40%，没有相关差异……
