| Outline of Final Research Achievements |
In the present study, 1) we developed experimental model that noninvasively increases exercising muscle blood flow during dynamic exercise in humans. In addition, 2) with this model we found that increase in muscle blood flow attenuates cardiovascular responses during dynamic exercise at higher than moderate intensity and improves endurance performance. Moreover, 3) our results indicate that inhibition of the muscle metaboreflex would be involved in the attenuation of the cardiovascular responses elicited by increases in exercising muscle blood flow. The results of this study contribute to elucidate the mechanisms of cardiovascular regulations during exercise, and will be an important scientific knowledge when considering safety of exercise and effectiveness of exercise training to improve exercise performance.
