This study aimed to clarify the effects of respiratory alkalosis induction on the kinetics of oxygen uptake at the onset of cycling exercise. We observed a difference in the time constant of oxygen uptake between the methods of respiratory alkalosis induction. It was considered that this difference was in relation to the changes in pH and concentration of bicarbonate ion in blood and the production of nitric acid during exercise.

本研究旨在阐明呼吸性碱中毒诱导对自行车运动开始时摄氧动力学的影响。我们观察到呼吸性碱中毒诱导方法之间的摄氧时间常数存在差异。人们认为这种差异与血液中pH值和碳酸氢根离子浓度的变化以及运动过程中硝酸的产生有关。
