Overview

May support microvascular benefits of aerobic training in hypertension; hypothesis-generating and requires RCT confirmation before practice change.

Structured PICO

Does 8 weeks of aerobic training improve skeletal muscle vasodilator formation in patients with essential hypertension?

P
Population
21 patients (10 with essential hypertension and 11 normotensive) evaluated before and after 8 weeks of aerobic training.
I
Intervention
8 weeks of aerobic training
C
Comparator
Pre-training baseline and normotensive control group
O
Outcome
Leg vascular conductance and interstitial adenosine and prostacyclin (PGI2) concentrations in skeletal musclesurrogate

Main Result

p-value: p=<0.05

Aerobic training normalizes the impaired capacity to form vasodilators (adenosine and PGI2) in the skeletal muscle microcirculation of patients with essential hypertension.

Cite This Study

Hellsten et al. (2012) studied Essential hypertension (n=21). Aerobic training vs. Pre-training baseline and normotensive controls was evaluated on Leg vascular conductance, interstitial adenosine, and prostacyclin (PGI2) concentrations (p=<0.05). Aerobic training for 8 weeks normalized the impaired formation of interstitial adenosine and prostacyclin at the skeletal muscle microcirculatory level in patients with essential hypertension.
