作者对男性少年的无氧阈和心输出量的测定中发现,在递增负荷运动中无氧阈的出现与心输出量增加速率减少有关;心脏泵血动能是影响无氧阈的重要因素,训练可增加前者,而后者在前者增加后才得以提高。
The authors measured the anaerobic threshold and cardiac output of male adolescents and found that the occurrence of anaerobic threshold during incremental load exercise was associated with a decrease in the rate of increase of cardiac output. Cardiac pumping kinetic energy was an important factor affecting the anaerobic threshold, and training The former can be increased, while the latter can be increased only after the former increases.
