我们使用心率和步行速度来计算能量消耗指数（EEI），即每米步行心率的比值，研究对象为102名6-18岁的正常受试者。在地板上和电动跑步机上自行选择慢速、舒适和快速行走速度来测量心率。当步行速度较慢（37 +/- 10 m/min）时，EEI升高（0.71 +/- 0.32次/m），表明经济状况较差。在舒适的速度下（70 +/- 11 m/min）， EEI值下降到最大的经济性（0.47 +/- 0.13节拍/m）。在高速行驶（101 +/- 13 m/min）时，EEI增加（0.61 +/- 0.17 beats/m），这表明与舒适的速度相比，经济性较差。EEI与步行速度的图表提供了一种评估和比较临床环境中能量消耗的方法。
We used heart rate and walking speed to calculate an energy expenditure index (EEI), the ratio of heart rate per meter walked, for 102 normal subjects, age 6-18 years. Heart rate was measured at self-selected slow, comfortable, and fast walking speeds on the floor and on a motor-driven treadmill. At slow walking speeds (37 +/- 10 m/min) the EEI was elevated (0.71 +/- 0.32 beats/m), indicating poor economy. At comfortable speeds (70 +/- 11 m/min) the EEI values decreased to the maximum economy (0.47 +/- 0.13 beats/m). At fast speeds (101 +/- 13 m/min), the EEI increased (0.61 +/- 0.17 beats/m), indicating poor economy relative to comfortable speeds. A graph of the EEI versus walking speed provides a way to evaluate and compare energy expenditure in a clinical setting.
