[Effects of muscular exertion in a hypoxic and hypoxic-hypercapnic respiratory environment on acid-base equilibrium and blood lactic acid in the albino rat raised in hypoxic hypoxia from birth].

Albino rats of the Wistar family were raised from the time of birth in the normobaric hypoxic environment. They were subjected at two subsequent equal trials of muscular work: the first in hypoxic normobaric conditions; the second in hypoxic hypercapnic conditions (CO2 = 2%). The modifications of the lactacidemia and acid-base balance at the end of the first trial are modest, lower than these observed in previous studies in normoxic rats. Added CO2 sensitively reduced the effects of the muscular work on the examined parameters.
