Diastolic coronary resistance (DCR) was studied in 10 conscious dogs in the untrained (UT) and partially trained (PT) condition. The PT regime consisted of treadmill running 5 days/wk for 4–5 wk. Left circumflex coronary flow, aortic pressure, and heart rate were measured, and diastolic coronary resistance (DCR) was calculated. Adrenergic blockade was achieved with propranolol (1 mg/kg, iv) (beta B) and phentolamine (1 mg/kg, iv) (alpha B). During submaximal exercise in the UT condition, DCR fell from a resting value of 3.84 +/- 0.24 Torr . ml-1 . min with increasing work load to 1.57 +/- 0.12 Torr . ml-1 . min at 6.4 km/h (speed)/16% (grade). The decrease in DCR during submaximal exercise was greater in the PT than in the UT condition. DCR following alpha-adrenergic blockade was not significantly changed in the UT and PT conditions (e.g., at 6.4 km/h (speed)/16% (grade), 1.10 +/- 0.141 vs. 1.03 +/- 0.107 Torr . ml-1 . min, whereas following beta-adrenergic blockade, DCR was larger in the UT compared with the PT condition (e.g., at 6.4 km/h (speed)/16% (grade), 2.03 +/- 0.091 vs. 1.73 +/- 0.073 Torr . ml-1 X min). Myocardial oxygen consumption was not significantly different in the PT and UT conditions, indicating no difference in metabolism with partial training. The present study suggests that during submaximal exercise in the PT condition there is a change in the neurogenic control of the coronary vasculature by a reduction in sympathetic neural activity on the coronary resistance vessels.
