Document Summary

Restrain the variation of blood pressure around a certain set point. It does not actually determine what blood pressure is, but rather it constraints the variability around the set point of blood pressure that the brain wants. It is necessary that the baroreflex set point (centre point) be reset to a higher blood pressure; this process is controlled by neural network regarding processes cognitive tasks, level of effort [central command processes] In order for blood pressure to rise, the baroreflex has to be reset. Metaboreflex and muscle pressor reflex mean the same thing. Metabo refers to metabolites produced in fatiguing skeletal muscle (autonomic neuro-reflex); This reflex is associated with increase in bp. Muscle press reflex (same as metaboreflex) reflex coming from skeletal muscles that cause the blood pressure to go up. The complex physiology of blood pressure regulation during fatiguing exercise. Early part is where the subject is at rest where the person is breathing (ventilation oscillation is small)
