背景:低水平的心肺适应性与高死亡风险相关,增加心肺适应性可降低死亡风险。但是,当前对体力活动与心肺适应性之间的量效关系尚缺乏了解。目的:研究NIH共识开发小组所建议体力活动量的50%、100%和
Background: Low-level cardiorespiratory fitness is associated with a high risk of death, and increased cardiorespiratory fitness may reduce the risk of death. However, there is currently a lack of understanding of the dose-response relationship between physical activity and cardiorespiratory fitness. Objectives: To study 50%, 100% of the recommended physical activity recommended by the NIH consensus development team
