The purpose of this study was to assess the impact of exercise rehabilitation (ER) on the daily physical activity (PA) of cardiopulmonary patients.
The impact of ER programs on the objectively measured quantity and quality of daily PA in cardiopulmonary patients is not completely understood.
Participants' exercise capacity and PA were measured at baseline and at the end of the ER program (n = 37).
Exercise capacity was higher at the end of the ER. Participants' sedentary time decreased while time spent in light PA increased; however, time spent in moderate-vigorous PA (MVPA) did not change. There was an increase in steps/day (>1.5 METs) and PA energy expenditure (PAEE) (>1.5 METs); whereas steps/day (≥3METs) and PAEE (≥3 METs) remained unchanged.
Findings imply that changes in daily PA in patients participating in ER occur in activities where the EE is in light intensity rather than in MVPA.
本研究旨在评估运动康复（ER）对心肺疾病患者日常身体活动（PA）的影响。
ER项目对心肺疾病患者日常PA的客观测量数量和质量的影响尚未完全明确。
在基线和ER项目结束时测量参与者的运动能力和PA（n = 37）。
ER结束时运动能力更高。参与者的久坐时间减少，而轻度PA的时间增加；然而，中度至剧烈PA（MVPA）的时间没有变化。每天的步数（>1.5代谢当量）和PA能量消耗（PAEE）（>1.5代谢当量）有所增加；而每天的步数（≥3代谢当量）和PAEE（≥3代谢当量）保持不变。
研究结果表明，参与ER的患者日常PA的变化发生在能量消耗为轻度强度的活动中，而非MVPA中。
