目标.本研究探讨了与低，中，高水平的心肺适能相关的身体活动模式。通过问卷调查对13444名男性和3972名女性（年龄在20至87岁之间）的临床人群的身体活动进行了评估。在低、中、高体能水平（通过最大运动试验评估）的个体中，计算报告活动的估计能量消耗（kcal.wk（-1））和体积（min.wk（-1））。男性平均休闲时间能量消耗为525至1650千卡·周（-1），女性为420至1260千卡·周（-1），与中到高水平的健康有关。这些能量消耗水平可以通过在一周的大多数日子里快走大约30分钟来实现。事实上，中等和高健身类别的男性步行时间在130和138分钟之间。wk（-1），这些类别的女性步行时间在148和167分钟之间。大多数人应该能够实现这些身体活动目标，从而达到足以产生实质性健康益处的心肺健康水平。
Objectives. This study examined cross sectionally the physical activity patterns associated with low, moderate, and high levels of cardiorespiratory fitness.Methods. Physical activity was assessed by questionnaire in a clinic population of 13 444 men and 3972 women 20 to 87 years of age. Estimated energy expenditure (kcal.wk(-1)) and volume (min.wk(-1)) of reported activities were calculated among individuals at low, moderate, and high fitness levels (assessed by maximal exercise tests).Results. Average leisure time energy expenditures of 525 to 1650 kcal.wk(-1) for men and 420 to 1260 kcal.wk(-1) for women were associated with moderate to high levels of fitness. These levels of energy expenditure can be achieved with a brisk walk of approximately 30 minutes on most days of the week. In fact, men in the moderate and high fitness categories walked between 130 and 138 min.wk(-1), and women in these categories walked between 148 and 167 min.wk(-1)Conclusions. Most individuals should be able to achieve these physical activity goals and thus attain a cardiorespiratory fitness level sufficient to result in substantial health benefits.
