Exercise prevents cardiometabolic alterations induced by chronic use of glucocorticoids.

Background: Chronically, glucocorticoids induce adverse cardiometabolic alterations including insulin resistance, diabetes, dyslipidemia, liver steatosis and arterial hypertension.

Objectives: To evaluate the effect of regular practice of aerobic exercise on cardiometabolic alterations induced by chronic administration of dexamethasone (Dex - 0.5 mg/kg/day ip) in rats.

Spontaneous respiratory modulation improves cardiovascular control in essential hypertension.

Background: Recent studies show that controlled breathing improves baroreflex and heart rate variability and lowers blood pressure in hypertensive patients.

Objective: To evaluate the effects of slow breathing training on cardiorespiratory system modulation of patients (n=10, men and women, ages ranging from 45 to 60) with essential hypertension seen in an outpatient setting.

Methods: According to the study design, each patient was used as his/her own control, and data were collected before and after the intervention.
