[Glycolytic metabolism during muscular excerise in chronic broncho-pulmonary disease without hypoxemia (author's transl)].

Maximum oxygen uptake (VO2 max) was measured in 11 chronic bronchitics without heart failure or hypoxemia at rest and during maximal work load, using a triangular type of excerise with increasing power (30 W/3 min). Glycolysis was studied in these patients during rectangular exercises lasting 10 minutes, in which power was increased by steps from an average value of 45 % to 72 and 94 % of VO2 max. The metabolic response of lactate in blood is similar to normal, during the limited performances of these patients.
