本研究探讨了低氧诱导的呼吸暂停对运动诱导的代谢性酸中毒和血浆乳酸和氨水平升高的影响。6名男性受试者进行递增强度运动直至力竭：（1）常氧（20.9%O-2）（=MAX），（2）低氧（12%O-2）（=HP），其中低氧条件从运动前60 min维持至运动后30 min，（3）与常氧条件下HP相同强度的运动（= HP）。从浅静脉抽取动脉化血液。HP组运动后血液pH值显著高于MAX组（P
The present study examined the effect of hypoxia-induced respiratory alkalosis on exercise-induced metabolic acidosis and increases in plasma lactate and ammonia levels. Six male subjects underwent exercise of increasing intensity until exhaustion: (1) in normoxia (20.9% O-2) (=MAX), (2) in hypoxia (12% O-2) (=HP) in which hypoxic condition had been maintained from 60 min before to 30 min after exercise, and (3) the same intensity of exercise as HP in normoxia (=SUB). Arterialized blood was drawn from a superficial vein. Post-exercise blood pH was significantly higher in HP than in MAX (P
