逐渐增加运动负荷时的生理变化过程在逐渐增加运动负荷时,从低强度到最大强度的运动可出现三个时期,图一分别描述了逐渐增加运动负荷时血乳酸、心率和气体代谢各项指标的典型变化。时相1:随着低的运动强度的增加,组织则摄取较多的氧气,从而导至呼出气中氧的含量百分数较低,同时,生成和呼出较多的 CO_2。另外,吸氧量(VO_2)、肺通气量(V_E)、CO_2排出量(VCO_2)以及心率呈直线增加。由于这种低强度稳定状
Gradual increase in exercise load when the physiological changes in the gradual increase in exercise load, from low intensity to the maximum intensity of the exercise there can be three periods, respectively, Figure 1 describes the gradual increase in exercise load blood lactate, heart rate and gas metabolism indicators Typical changes. Phase 1: With low exercise intensity, the tissue takes in more oxygen, leading to a lower percentage of oxygen in the expired air, while generating and exhaling more CO 2. In addition, the amount of oxygen (VO_2), pulmonary ventilation (V_E), CO_2 emissions (VCO_2) and heart rate increased linearly. Due to this low-intensity stability
