Observational population-based studies have consistently shown an inverse dose-response gradient between physical activity or fitness and coronary heart disease. This relationship is more firmly established in men. Existing studies suggest that the physical activity gradient, and perhaps the fitness gradient, is produced by a combination of varying levels of both the intensity and the amount of habitual physical activity. It is not at present possible to definitively describe the dose-response association between the intensity of physical activity and the risk of coronary heart disease. An answer to this important question awaits further research.
基于人群的观察性研究一直表明，身体活动或健康状况与冠心病之间存在反向剂量反应梯度。这种关系在男性中更为确定。现有研究表明，身体活动梯度，或许还有健康状况梯度，是由习惯性身体活动的强度和量的不同水平共同作用产生的。目前还无法确切描述身体活动强度与冠心病风险之间的剂量反应关联。这个重要问题的答案有待进一步研究。
