高原是神秘的。运动员一下飞机,机体内就会发生一I闲系列变化。这些变化包括血液含氧量降低,血容量下降,心搏量、心输出量减少。还可观察到呼吸加快、体液丢失,心率及基础代谢加快。 产生这些变化的原因在于高原氧分压降低,高原训练时需要更多的氧,因而上述变化会进一步加剧。这些 Plateau is mysterious. Athletes about the plane, the body will happen a leisure series changes. These changes include decreased blood oxygen content, decreased blood volume, stroke volume, cardiac output decreased. Can also be observed to accelerate breathing, loss of body fluids, heart rate and basic metabolism to speed up. The reason for these changes is the reduction of the partial pressure of oxygen in the plateau and the need for more oxygen in plateau training, thus further aggravating the above changes. These ones
