The study on training which apply the specific physiological responses by hypercapnic gas inhalation

吸入高二氧化碳气体刺激呼吸中枢，激活心肺系统。这种特殊的生理反应被应用到运动训练中。耐力运动员在两周内每天吸入一小时的高二氧化碳气体。我们发现间歇吸入高二氧化碳气体可增强高二氧化碳的呼吸反应，促进运动时的最大通气量。由此可见，间歇性高二氧化碳气体吸入可提高耐力运动员的换气能力。

Hypercapnic gas inhalation stimulates the respiratory center, and activates the cardiorespiratory systems. This specific physiological response was applied to sports training. Endurance athletes performed hypercapnic gas inhalation for one hour each day for two weeks. We showed that intermittent hypercapnic gas inhalation enhances hypercapnic ventilatory response and promotes the maximal ventilation during exercise. From the present results, it is suggested that intermittent hypercapnic gas inhalation may promote a ventilatory capacity in endurance athletes.
