Blood Pressure Control at Rest and during Exercise in Obese Children and Adults

Figure 2

Alterations in the control of blood pressure during exercise in obese individuals: the baroreflex is less sensitive to stimulation (i.e., exercise) and the metaboreflex is blunted. Mechanically sensitive afferent neurons may therefore undergo functional changes to compensate for the reduced metaboreflex. These alterations may promote chronic adjustments in peripheral vascular resistance, precipitate fatigue during exercise and delay vasodilatation during exercise recovery. HR: Heart Rate; SV: Stroke Volume; TPR: Total Peripheral Resistance.
