exercise pressor reflex

ex·er·cise pres·sor re·flex

(eks'ĕr-sīz pres'ŏr rē'fleks)
Reflex afferent neural input to the cardiovascular center in the medulla from proprioceptors (mechanoreceptors and metaboreceptors) in active muscles during exercise.

This has been termed as the exercise pressor reflex and explained as follows: [19] Two types of stimuli, mechanical and chemical, are thought to activate these muscle nerve fiber endings and trigger this reflex.
Hemodynamic regulation by this reflex loop, termed as the exercise pressor reflex, is primarily mediated by the increased efferent sympathetic nerve activity [9].
As tlie existing skeletal muscles have chemoreceptors that drive the exercise pressor reflex, massive sympathoexcitation is driven during exercise.
The increase in arterial pressure evoked by activation of the exercise pressor reflex, the stimulation of the baroreflex receptors, and the control of the arterial pressure are a function of the subjects' cardiovascular response to the exercise (25).
Forearm training reduces the exercise pressor reflex during ischemic rhythmic handgrip: Journal of Applied Physiology 1998; 84: 1277-283.
The polynomial pattern response was most certainly a reflection of the many ways that the central command and the exercise pressor reflex can respond to allow for patterned HR responses in spite of impending volitional fatigue (10,12,14,15,19,22,24,25,31).
The combination of central command and the exercise pressor reflex response differed for each of the 10 cyclists as their biological systems attempted to address increasing metabolite concentrations, the inability of the baroreceptor to operate at a higher point, and fatiguing cardiovascular mechanism (28,29,36).
