Global and segmental left ventricular dynamics during strenuous large-muscle isometric exercise were compared between endurance and static type professional athletes and sedentary men. Using a trunk dynamometer and supine echocardiography, only the weight lifters manifested increased (p < 0.01) wall thickness during both diastole and systole, resulting in decreased left ventricular volume at end systole. These group-related differences would suggest a causal relationship between chronic intensive weight-lifting training and efficient myocardial dynamics at the time of strenuous isometric exercise.
对耐力型和静力型职业运动员以及久坐男性在剧烈大肌肉等长运动期间的整体和节段性左心室动力学进行了比较。使用躯干测力计和仰卧位超声心动图，只有举重运动员在舒张期和收缩期均表现出壁厚增加（p<0.01），导致收缩末期左心室容积减小。这些与组相关的差异表明，长期高强度举重训练与剧烈等长运动时高效的心肌动力学之间存在因果关系。
