The cardiovascular response to exercise is largely determined by neurocirculatory control
mechanisms that help to raise blood pressure and modulate vascular resistance which, in …

Current theory is that circulatory control in exercise is governed by central command which
sets basic patterns of effector activity that is modulated by arterial baroreflexes and chemo …

During physical activity, there is a graded withdrawal of vagal cardiac tone and a graded
increase in sympathetic cardiac and vasomotor tone, initiated through both central command …

The present review examines the control of muscle vascular conductance by the
sympathetic nervous system during exercise. 2. Evidence for tonic sympathetic neural …

New Findings• What is the topic of this lecture? Sir William Paton, a distinguished physician
scientist, was interested in the origins of concepts in physiology. This lecture explores the …

Autonomic nervous system adjustments to the heart and blood vessels are necessary for
mediating the cardiovascular responses required to meet the metabolic demands of working …

On the basis of measurement techniques that require steady-state hemodynamic conditions
when the measurement of cerebral blood flow (CBF) is being obtained, cerebral …

The overall scheme for control is as follows: central command sets basic patterns of
cardiovascular effector activity, which is modulated via muscle chemo-and mechanoreflexes …

This brief review examines five problems concerning arterial blood pressure regulation
during exercise. These are: 1. A history and summary of evidence that baroreflexes are, or …

Power spectra of instantaneous heart rate (fc) allows the estimation of the contribution of
sympathetic and parasympathetic control of fc during steady-state conditions. The present …
