Abstract

Cardiorespiratory dynamics was tested in 10 men exercising with a relative intensity of 50% VO2max for 10 min. Time constants for cardiac response (SV 21.7 sec, HR 45.8 sec, Q 21.7 sec) were shorter than those for the ventilatory response (of 27.4 sec, VT 70 sec, VE 69.5 sec). Respiratory dynamics was significantly related to the level of VO2max exhibited by the subjects: (f) r = 0.79, p less than 0.02; (VT) r = 0.63, p less than 0.05; (VE) r = 0.78, p less than 0.01. It is concluded that in man the dynamics of the ventilatory response to exercise depend on the actual level of VO2max in the individual.

摘要

对10名男性进行了心肺动力学测试，他们以50%最大摄氧量（VO2max）的相对强度运动10分钟。心脏反应的时间常数（每搏输出量21.7秒、心率45.8秒、心输出量21.7秒）短于通气反应的时间常数（潮气量27.4秒、分钟通气量70秒、每分通气量69.5秒）。呼吸动力学与受试者表现出的最大摄氧量水平显著相关：（潮气量）r = 0.79，p < 0.02；（每分通气量）r = 0.63，p < 0.05；（每分通气量）r = 0.78，p < 0.01。得出的结论是，在人类中，运动通气反应的动力学取决于个体的实际最大摄氧量水平。
