| Research Abstract |
Endurance exercise training decreases resting blood pressure and increases blood flow distribution to skeletal muscles during exercise. To reveal the mechanisms of an adaptive change in cardiovascular regulation associated exercise training, muscle sympathetic nerve activity and catecholamine as neural and humoral factors were measured during submaximal exercise in endurance trained and untrained subjects. Sympathetic neural responses were greater in the trained than in the untrained group. However, the response of the humoral factors was the same in both groups. These results indicate that an effect of the exercise training on neural and humoral responses for cardiovascular regulatory mechanisms is not identical.
