Reciprocating pumps convert rotary motion to linear motion. Pump speed in RPM determines the pumps output volume for any given combination of cylinder bore and piston stroke.
循环泵将曲轴旋转运动转化为柱塞的直线运动。泵速转每分钟决定了任何气缸和活塞组合的排泵量。
Increases Cardiac Output, stronger heart contractions pump more blood, increased stroke volume, thickens left ventricle wall (more muscular), decreases hearts' oxygen requirements.
心输出量增加，心脏收缩加强能泵更多的血液，心搏量增加，左心室壁变厚(更多肌肉)，心脏对氧气的需要减少。
Endurance training results in an increase in oxygen consumption and delivery. Stroke volume and cardiac output increase. Peripheral vascular resistance decreases.
耐力训练导致耗氧量和清除量增加，心脏搏出量和输出量增加，外周血管阻力下降。
