| Research Abstract |
We investigated the integrative responses among peripheral reflex mechanisms during orthostatic stress, breath-holding during exercise, and handgrip exercise in humans. 1) It was suggested that both the arterial baroreflex and local intrinsic vascular regulatory mechanisms contribute to the blood flow regulation in upper and lower limbs during orthostatic stress. 2) It was suggested that the muscle metaboreflex contributes to the increase in blood pressure response seen during breath-holding during dynamic exercise in humans. 3) It was suggested that the heart rate response to activation of muscle metaboreflex varies considerably from individual to individual, and that these differences reflect changes in cardiac parasympathetic tone and the sensitivity of the spontaneous arterial baroreflex control during the activation of muscle metaboreflex.
