Exercise Pressor Reflex Dysfunction in Hypertension
The exercise pressor reflex and its components, the muscle mechanoreflex and the metaboreflex, are overactive in hypertension. The mechanoreflex and metaboreflex are feedback mechanisms originating in skeletal muscle that increase mean arterial pressure (MAP) and heart rate (HR) during exercise. In …

EFFECTS OF ACUTE NORMOBARIC HYPOXIA DURING EXERCISE AND CONCURRENT MENTAL STRESS ON THE CARDIOVASCULAR SYSTEM IN HEALTHY ATHLETES
BACKGROUND: Exercise and hypoxia are individually recognized as physiological stressors that challenge cardiovascular homeostasis through mechanisms orchestrated by medullary cardiovascular control centers. During physical exertion, the activation of the “exercise pressor reflex” facilitates …

Valutazione degli aggiustamenti cardiocircolatori nel motociclismo classe enduro
… motorcycle race. The comparison between rest and exercise showed a significant increase in hemodynamic parameters. In detail, increments in both HR and SV were observed, thereby leading to a CO elevation. Systemic Vascular Resistance (SVR) showed a significant reduction, while there was an …

Central Neural Cardiorespiratory Areas in Exercise
"Neural control of cardiorespiratory function in exercise is accomplished by two mechanisms: a reflex arising from contracting muscles termed ""exercise pressor reflex"", and a ""central command"" mechanism. The three experiments described in this thesis were concerned with fundamental issues …

Muscle Metaboreflex Control Of Cardiovascular Function In Hypertension
… muscle ischemia during or immediately following exercise leads to the accumulation of metabolites (e.g., lactate, proton and diprotonated phosphate) which activate chemoreceptive afferents within the muscle leading to a reflex increase in sympathetic outflow generating substantial increases in …
