本研究旨在研究大强度有氧间歇耐力训练对冠心病患者最大每搏输出量和最大力量训练对机械效率的影响。8例冠心病患者(年龄61.4+/-3.7岁)以峰值心率的85~95%进行30次4x4min间歇训练，10例冠心病患者(年龄66.5+/-5.5岁)进行24次最大水平推腿训练。间歇训练组最大每搏输出量由94.1+/-23.0mL显著增加23%。将(-1)打至115.8+/-22.4mL。节拍(-1)(p<；0.05)。峰值摄氧量从27.2+/-4.5mL显著增加了17%。Kg(-1)。Min(-1)至31.8+/-5.0mL.Kg(-1)min(-1)(P<0.05)。相比之下，尽管亚极量步行能力提高了35%，但最大力量训练组的最大每搏出血量或最大摄氧量并没有因运动训练而改变。
This study sought to study the effect of high intensity aerobic interval endurance training on peak stroke volume and maximal strength training on mechanical efficiency in coronary artery disease (CAD) patients. 8 CAD patients (age 61.4 +/- 3.7 years) trained 30 interval training sessions with 4 x 4 min intervals at 85-95% of peak heart rate while 10 CAD patients (age 66.5 +/- 5.5 years) trained 24 sessions of maximal horizontal leg press. In the interval training group peak stroke volume increased significantly by 23% from 94.1 +/- 23.0 mL . beat(-1) to 115.8 +/- 22.4 mL . beat(-1) (p < 0.05). Peak oxygen uptake increased significantly by 17% from 27.2 +/- 4.5 mL . kg(-1) . min(-1) to 31.8 +/- 5.0 mL . kg(-1) min(-1) (p < 0.05) in the same group. In contrast, there was no such exercise training-induced change in peak stroke volume or peak oxygen uptake in the maximal strength training group, despite a 35% improvement in sub maximal walking performance.
