摘要：The highest level of the cardiac output is said to be closely related to the maximum oxygen intake. In the present work, maximum cardiac output was studied with repeat to sex and age. The trained and the untrained were also compared. A modified CO method was used to determine cardiac output. For measuring oxygen intake, the expired gas, collected by the Douglas bag method in exhaustive ex6rcise on a treadmill, was analyzed by Scholander's apparatus. Normal 178 males and 58 females served as the subjects. Maximum cardiac output increased with age, whose average values were 18.7 l/min at age 12-15, 21.6 l/min at age 16-20, 22.1 l/min at age 21-25 in male subjects; 14.9 l/min at age 13-15, 15.4 l/mit at age 16-18, 15.9 l/min at age 19-23 in female subjects respectively. After these age, maximum cardiac output gradually declared in advance of age. A higher average was found to be 27.0 l/min in the trained male subjects. The maximum cardiac output (Qmax) appeared to be a little lower than those of European Reported by Astrand and Holmgren. But, comparing the cardiac output per body weight, no difference was found among those different populations.
