This study examined the relationship between total energy cost and cardiac effort for a set of graded calisthenics that have been used in cardiac rehabilitation programs. Cardiac effort was quantified by calculating myocardial oxygen cost from the product of heart rate and systolic blood pressure. Total energy cost was determined by measuring oxygen uptake during steady-state exercise. Results indicate that total energy-cost values accurately reflect the cardiac effort required during the performance of these calisthenic exercises by normal subjects.
本研究调查了一组已用于心脏康复项目的分级健美操的总能量消耗与心脏负荷之间的关系。通过心率与收缩压的乘积计算心肌氧耗，以此来量化心脏负荷。通过测量稳态运动期间的摄氧量来确定总能量消耗。结果表明，总能量消耗值准确反映了正常受试者在进行这些健美操运动时所需的心脏负荷。
