Increasing energy expenditure (EE) in cardiac patients remains a challenge. Exercise approaches in cardiac rehabilitation/secondary prevention programs (CR/SP) have consistently resulted in minimal weight loss, due in part to the low exercise-related EE. The purpose of this study was to measure the EE among patients participating in a routine exercise session of Phase III maintenance CR/SP, where a recreational activity was introduced. Twelve overweight/obese male patients with coronary artery disease (aged 62.6 ± 8.5 years) had their total EE measured during a combined aerobic (circuit workout (ACW) and recreational activity) and resistance training (RT) session using a portable gas analyzer. Subjects were instructed to exercise at 60%-70% of heart rate reserve. Activity EE was calculated from total EE and resting EE. The duration of the session was 75.3 ± 1.5 min, of which 59.7 ± 8.8 min were above moderate intensity (3-6 METs). Activity EE was 309 ± 76 kcal, concurring to a total EE of 457 ± 80 kcal (3.9 ± 0.8 METs-h). ACW, recreational activity, and RT fulfilled 34.4% ± 6.4%, 25.0% ± 5.3%, and 14.2% ± 2.7% of the activity EE, respectively. Absolute intensities (METs) were significantly different between the RT (3.9 ± 1.0) and the ACW (6.9 ± 1.8) and recreational activity (5.9 ± 0.8). In conclusion, a combined aerobic and resistance training following standard exercise prescription practices, coupled with a recreational activity, is an effective tool to promote exercise above moderate intensity in male coronary artery disease patients. Clinicians can adopt concepts from recreational activity to develop CR/SP sessions.
增加心脏病患者的能量消耗 (EE) 仍然是一个挑战。心脏康复/二级预防计划 (CR/SP) 中的运动方法一直导致体重减轻最小，部分原因是运动相关 EE 较低。本研究的目的是测量参加常规 III 期维持性 CR/SP 运动课程的患者的 EE，其中引入了娱乐活动。12 名超重/肥胖的冠心病男性患者（年龄 62.6±8.5 岁）使用便携式气体分析仪在有氧（电路锻炼 (ACW) 和娱乐活动）和阻力训练 (RT) 联合训练期间测量他们的总 EE。受试者被指示以心率储备的 60%-70%进行运动。活动 EE 是从总 EE 和静息 EE 中计算得出的。该课程持续 75.3±1.5 分钟，其中 59.7±8.8 分钟的运动强度在中等强度以上（3-6 METs）。活动 EE 为 309±76kcal，总 EE 为 457±80kcal（3.9±0.8METs-h）。ACW、娱乐活动和 RT 分别满足活动 EE 的 34.4%±6.4%、25.0%±5.3%和 14.2%±2.7%。RT（3.9±1.0）与 ACW（6.9±1.8）和娱乐活动（5.9±0.8）的绝对强度（METs）有显著差异。结论：在遵循标准运动处方实践的基础上，结合有氧运动和阻力训练，再加上娱乐活动，是一种有效的工具，可以促进男性冠心病患者进行高于中等强度的运动。临床医生可以从娱乐活动中汲取概念，开发 CR/SP 课程。
