This study was designed to assess and characterize the physical activity levels and patterns of participants in a hospital-based Phase III cardiac rehabilitation (CR) program.
Subjects consisted of 25 men with a history of coronary artery disease ranging in age from 39 to 69 years who were participating in a Phase III CR program. Physical activity in steps and energy expenditure were assessed for 7 days using an accelerometer (Actigraph GT1M). Comparisons were made between CR days and non-CR days. In addition, physical activity within and outside the CR session was also compared.
Subjects attended CR 3.0 +/- 1.0 d/wk (mean +/- SD) and averaged 6,907 +/- 510 steps/d (mean +/- SE) over 7 days. Physical activity levels were significantly higher on CR days versus non-CR days (10,087 +/- 631 vs 5,287 +/- 520 steps/d). Those who performed home exercise in addition to CR were significantly more active than CR-only exercisers (7,993 +/- 604 vs 5,277 +/- 623 steps/d).
These results suggest that a majority (52%) of CR participants met a minimal active goal on days they attend CR. However, only 8% reached the recommended minimum level of weekly physical activity. Those that did some form of home-exercise in addition to CR were significantly more active than the CR only exercisers. Although attending CR seems to help patients reach physical activity targets, patients should be strongly encouraged to increase their volume of physical activity either at the CR facility or at home. Activity monitors provide a practical and effective way for patients to track their physical activity levels, which may be helpful in reaching goals.
本研究旨在评估和描述参与医院第三阶段心脏康复（CR）项目的参与者的身体活动水平和模式。
研究对象为25名年龄在39至69岁之间、有冠状动脉疾病史且正在参与第三阶段CR项目的男性。使用加速度计（Actigraph GT1M）对步数和能量消耗进行7天的身体活动评估。对CR日和非CR日进行比较。此外，还比较了CR课程内外的身体活动情况。
受试者每周参加CR 3.0 +/- 1.0天（平均值 +/- 标准差），7天内平均每天6,907 +/- 510步（平均值 +/- 标准误）。CR日的身体活动水平显著高于非CR日（分别为10,087 +/- 631步/天和5,287 +/- 520步/天）。除CR外还进行家庭锻炼的参与者比仅进行CR锻炼的参与者明显更活跃（分别为7,993 +/- 604步/天和5,277 +/- 623步/天）。
这些结果表明，大多数（52%）CR参与者在参加CR的日子里达到了最低活动目标。然而，只有8%的人达到了建议的每周身体活动最低水平。除CR外还进行某种形式家庭锻炼的参与者比仅进行CR锻炼的参与者明显更活跃。尽管参加CR似乎有助于患者达到身体活动目标，但应强烈鼓励患者在CR机构或家中增加身体活动量。活动监测器为患者提供了一种实用且有效的方式来跟踪他们的身体活动水平，这可能有助于实现目标。
