Strong evidence supports positive correlation of physical activity with health benefits. Current recommendations by the American Heart Association are a minimum 30 minutes of moderate physical activity 5 days per week. This goal has been equilibrated with 10,000 steps per day.
Work-related physical activity of cardiovascular (CV) specialists does not meet the currently recommended daily physical activity.
Eight cardiothoracic (CT) surgeons, 7 general cardiologists, 5 procedural cardiologists, and 8 cardiac anesthesiologists (N = 28) participated in the study. Demographic information on each participant was recorded including age, resting heart rate, body mass index, and medical and social history. Subjects were asked to wear a spring-levered pedometer on their hip for 2 weeks while at work and to record the total number of steps as well as number of hours worked each day.
The average daily steps walked during work were 6540, 6039, 5910, and 5553 for general cardiologists, CT surgeons, procedural cardiologists, and cardiac anesthesiologists, respectively. There were no statistically significant differences in the average number of steps taken per day among the groups. CT surgeons worked 12.4 hours per day compared to 9.3 hours by the cardiac anesthesiologists (P = 0.03).
In this small, single-center study, work-related physical activity of CV specialists did not meet the recommended guidelines. Obtaining the recommended activity level might be a challenge, given their busy work schedule. Therefore, CV specialists must engage in additional, out-of-hours exercise to achieve the recommended daily exercise.
有强有力的证据表明,身体活动与健康益处呈正相关。目前,美国心脏协会的建议是每周至少进行 5 天、每天 30 分钟的中等强度身体活动。这一目标与每天走 10000 步相平衡。
心血管专家的工作相关身体活动不符合目前推荐的日常身体活动量。
8 名心胸外科(CT)外科医生、7 名普通心脏病专家、5 名介入心脏病专家和 8 名心脏麻醉师(共 28 名)参与了这项研究。记录了每位参与者的人口统计学信息,包括年龄、静息心率、体重指数以及医疗和社会史。要求受试者在工作时佩戴一个带弹簧杆的计步器两周,记录每天的总步数和工作时间。
普通心脏病专家、CT 外科医生、介入心脏病专家和心脏麻醉师在工作期间平均每天行走的步数分别为 6540、6039、5910 和 5553。各组之间每天行走的平均步数没有统计学差异。CT 外科医生每天工作 12.4 小时,而心脏麻醉师每天工作 9.3 小时(P = 0.03)。
在这项小型单中心研究中,心血管专家的工作相关身体活动量不符合推荐指南。考虑到他们繁忙的工作安排,获得推荐的活动水平可能是一个挑战。因此,心血管专家必须在工作时间之外进行额外的运动,以达到推荐的日常运动量。
