Abstract
Abstract The bradycardia effect of a 10-week jogging program was studied in 13 previously sedentary middle-aged subjects (seven women and six men). This response during standardized submaximal treadmill walking and leg cycling was related to changes in cardiac output ([Qdot]), stroke volume (SV), and arteriovenous oxygen differences (a-vO2 diff). Heart rate (HR) response was also studied during load carrying and arm cycling tasks, and a [Vdot]O2 max test was administered. All tests were repeated posttraining. The posttraining increases in [Vdot]O2 max (ml/kg × min-1) were 19.7% and 14.8% for the men and women respectively. Training also produced significant reductions in submaximal HR and Q during treadmill and leg cycling exercise. A-vO2 diff rose, while there were no changes in [Vdot]O2 during the submaximal work tasks, suggesting either altered blood flow or a greater capacity to utilize O2 by the working muscle. Both men and women showed significant reductions in HR during the arm cycling and load car...
