Abstract :
Measurements of nine impedance cardiograph variables made on 17 young (21-29 yr, mean 24.6 yr), healthy males during rest and three levels of treadmill and hand-crank exercise showed no significant difference (ANOVA, p>0.05) among the three days, except for heart rate (p<0.01, treadmill; p<0.02, hand crank), time-to-aortic closing (p<0.01, treadmill), and mean thoracic impedance (p<0.01, hand crank). Stroke volume, cardiac output, time-to-peak ejection, time-to-aortic opening, (dZ/dt)peak, and d2Z/dt 2 were invariant with day of exercise
