N2 - The effect of training on the regional blood flow response to maximal exercise was investigated in the foxhound. Training consisted of 8-12 wk of treadmill running at 80% of maximal heart rate 1 h/day for 5 days/wk and resulted in a 31% increase in maximal O2 consumption, a 28% increase in maximal cardiac output, and a 23% decrease in systemic vascular resistance during maximal exercise. Blood flow to the heart, diaphragm, brain, skin, and 9 of 10 muscles investigated was similar during maximal exercise pre- and posttraining; however, blood flow to the gastrocnemius muscle was greater posttraining than it was pretraining. Blood flow to the stomach, small intestine, and pancreas decreased during maximal exercise pre- and posttraining; however, blood flow to the large intestine, spleen, liver, adrenal glands, and kidneys decreased during maximal exercise only posttraining. In addition, a larger decrease in blood flow to the stomach during maximal exercise was found posttraining compared with pretraining. These results demonstrate that blood flow to skeletal muscle, the kidneys, and the splanchnic region of the foxhound during maximal exercise can be significantly altered by dynamic exercise training.
