The relationships between physical activity, physical fitness, and coronary heart disease risk factors measured in a large community sample were evaluated. Self-reported physical activity using a single question, maximal oxygen consumption estimates derived from the Pawtucket Heart Health Step Test, blood pressure, nonfasting lipids, and body mass index were cross-sectionally evaluated in 381 men and 556 women. The correlation of estimated maximal oxygen consumption and self-reported physical activity was modest but statistically significant (r = 0.13 in men and r = 0.19 in women). Blood pressure, body mass index, and HDL cholesterol were correlated with physical fitness (r = 0.24-0.65) and correlated to self-reported physical activity (r = 0.09-0.14). Evaluation of coronary heart disease risk factors using both physical activity and physical fitness revealed a complex relationship that generally showed a stronger relationship with measures of physical fitness than with physical activity. This study suggests that simultaneous measurement of physical activity and physical fitness may be useful in epidemiologic studies of habitual physical activity and chronic disease.
在一个大型社区样本中，对体力活动、体能与冠心病风险因素之间的关系进行了评估。使用单个问题进行自我报告的体力活动、通过波塔基特心脏健康台阶试验得出的最大摄氧量估计值、血压、非空腹血脂和体重指数，在381名男性和556名女性中进行了横断面评估。估计的最大摄氧量与自我报告的体力活动之间的相关性中等，但具有统计学意义（男性r = 0.13，女性r = 0.19）。血压、体重指数和高密度脂蛋白胆固醇与体能相关（r = 0.24 - 0.65），并与自我报告的体力活动相关（r = 0.09 - 0.14）。使用体力活动和体能对冠心病风险因素进行评估，揭示了一种复杂的关系，总体而言，与体能指标的关系比与体力活动的关系更强。这项研究表明，同时测量体力活动和体能可能有助于习惯性体力活动和慢性病的流行病学研究。
