获得身体活动能量消耗（PAEE）的准确测量值可能很困难，因此每天步数的简单测量已在普通人群中得到广泛推广和接受。然而，PAEE和每天的步骤之间的关系还没有进行评估，在患者与心血管diseases.Methods和结果共77（53名男性，24名女性）心脏康复计划的参与者，年龄在46和88岁。通过加速度计，对每名受试者每天的步数、PAEE的量以及每天在轻度（< 3代谢当量（MET））、中度（3 - 6 MET）和剧烈（> 6 MET）强度下的身体活动中花费的时间进行评价。每日步数与总PAEE（r=0.92，p < 0.001）和中等强度至剧烈强度体力活动（r=0.85，p < 0.001）的时间密切相关。平均（95%置信区间）与214和314 kcal/天相关的步数（即1,500和2,200千卡/周）分别为6,470和8,496步/天。结论要达到心血管疾病二级预防一般推荐的PAEE总量，应鼓励患者累积6,500 - 8，500步/天。
Background Obtaining an accurate measure of physical activity energy expenditure (PAEE) can be difficult, so the simple measurement of steps per day has become widely promoted and accepted in the general population. However, the relationship between PAEE and steps per day has not been evaluated in patients with cardiovascular disease.Methods and Results A total of 77 (53 men, 24 women) cardiac rehabilitation program participants aged between 46 and 88 years were enrolled. By means of an accelerometer the step count per day, amount of PAEE, as well as time per day spent in physical activity at light (< 3 metabolic equivalents (METs)), moderate (3 - 6 METs) and vigorous (> 6 METs) intensity were evaluated for each subject. The number of daily step counts strongly correlated with total PAEE (r=0.92, p < 0.001) and time spent in moderate to vigorous intensity physical activity (r=0.85, p < 0.001). The mean (95% confidence intervals) step counts associated with 214 and 314 kcal/day (ie, 1,500 and 2,200 kcal/week) were 6,470 and 8,496 steps/day, respectively.Conclusion To achieve the total amount of PAEE generally recommended for the secondary prevention of cardiovascular disease, patients should be encouraged to accumulate 6,500 - 8,500steps/day.
