This study examined cross sectionally the physical activity patterns associated with low, moderate, and high levels of cardiorespiratory fitness.
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).
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.
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.
本研究横断面调查了与低、中、高水平心肺适能相关的身体活动模式。
通过问卷调查评估了13444名男性和3972名年龄在20至87岁之间的女性门诊患者的身体活动情况。计算了低、中、高适能水平个体（通过最大运动测试评估）报告活动的估计能量消耗（千卡·周-1）和运动量（分钟·周-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，与中高水平的适能相关。这些能量消耗水平可以通过每周大多数日子快走约30分钟来实现。事实上，中高适能类别的男性每周步行130至138分钟，女性则为148至167分钟。
大多数人应该能够实现这些身体活动目标，从而达到足以带来显著健康益处的心肺适能水平。
