Abstract

Albino rats of the Wistar family were subjected at three subsequent equal trials of muscular work: the first in normoxyc conditions; the second in hypoxic normobaric conditions; the third in hypoxic-hypercapnic normobaric conditions. The modifications of the lactacidemia, pyruvicemia and acid-base balance were greatest at the end of hypoxic trial. Added CO2 (2%) sensitively reduced the acidificant effects of the muscular work on the acid-base balance.

摘要

选用Wistar品系的白化大鼠，进行了三次连续的同等强度肌肉运动试验：第一次在常氧条件下；第二次在低氧常压条件下；第三次在低氧高碳酸血症常压条件下。乳酸血症、丙酮酸血症和酸碱平衡的变化在低氧试验结束时最为显著。添加2%的二氧化碳可灵敏地减轻肌肉运动对酸碱平衡的酸化作用。
