摘要:

Resumé.Muscular exertion brings about a reduction of the alkali reserve in the blood and a decrease in the blood's pH, i.e., there occurs a non‐compensated acidosis. The lactic acid combines with the sodium bicarbonate of the blood. Bicarbonate administered per os occasions a fall in the lactic acid concentration in the blood, while at the same time thers comes an augmented excertion of lactic acid in the urine. Physical exertion after administration of bicarbonate per os does not occasion such severe hyperlactacidæmia as corresponding exertions without bicarbon

摘要:

Resumé.The obove‐mentioned investigationns show that after intense muscular exertion there was present a condierable oxygen deficit, which in the course of the first minutes after cessation of the exercises was compensated for by an intake of oxygen that was considerably sugmented as compared with the intake during rest. This increased intake of oxygen, the debt, corresponds to a certain extent to the quantity fo oxygen which theoretically should be required for oxidation of the lactic acid accumulated in the organism. The oxygen content in the venous blood from the arm is in most cases found to be somewhat augmented after exercise on the cycle‐ergometer, while in a few especially severe from exercise it has slightly diminished. The increase, in oxygen content in the blood from the vein in the arm must be explained as being due to a more rapid circulation of the blood. On respiration in various mixtures of oxygen there is seen an increase in the quantity of lactic acid when the oxygen content in the inspiration air is 7.5%, corresponding to partial pressure of 57 mm. Hg., which will be found at a height of about 8000 m. oer sea level. It is probable that the muscular fatigue which is one of the symptoms of mountain sickness is due to an accumulation of lactic acid. In case of shortage of oxygen several minutes must elapse before the quantity of lactic acid in the venous blood increase. When the circulation of the blood is restricted locally, there is seen a considerable increase of the lactic acid in in the venous b
