International Journal of Exercise Science: Conference Proceedings

The skeletal muscle metaboreflex is a blood pressure-raising reflex originating from skeletal muscle that contributes to resetting the operating point of the arterial baroreflex during exercise. In healthy adults, sympathetic baroreflex sensitivity (BRS) increases during metaboreflex activation, whereas cardio-vagal BRS is unchanged. Adults with hypertension (HTN) have exaggerated pressor responses to metaboreflex activation; however, to our knowledge, no studies have examined sympathetic or cardio-vagal BRS during metaboreflex activation in adults with HTN. HYPOTHESIS: We hypothesized that sympathetic and cardio-vagal BRS would be reduced during graded muscle metaboreflex activation in adults with HTN. METHODS: Thirty-five adults with HTN (18 …
