Physical Exercises Influence on Blood Pressure and Arterial Stiffness

Arterial Hypertension

Regular exercise is recommended as an adjuvant treatment in hypertensive subjects by both European and American guidelines. Crucially, however, there are no precise recommendations on the type of physical exercise and how it should be instituted A relatively short period (5 months) of regular aerobic interval training (AIT), significantly decreased blood pressure, pulse wave velocity, and most applanation tonometry indexes in hypertensive subjects also undertaking pharmacological treatment in our study.

Regular physical exercise appears to potentiate the effects of pharmacological treatment for arterial hypertension. As such, regular exercise is recommended as an adjuvant treatment in hypertensive subjects by both European and American guidelines. Crucially, however, there are no precise recommendations on the type of physical exercise and how it should be instituted. Aerobic Interval Training (AIT) is a new and novel type training that appears to be beneficial to patients suffering from various medical conditions. There is a distinct lack of evidence on how it affects arterial hypertension. The aim of this study was to evaluate the influence of a 5 month period of regular AIT on blood pressure, carotid femoral pulse wave velocity (PWV) and applanation tonometry indexes in patients previously treated pharmacologically for mild or moderate arterial hypertension. The study group consisted of 60 hypertensive subjects (30 males, 30 females) (age 54.45 ± 8.52 years) who had previously undergone at least 2 years of combined anti-hypertensive therapy and who had well controlled hypertension, i.e. below 140/90 mmHg. Their pharmacological treatment did not change during the study period. The study group was randomly divided into 2 subgroups. In the first group (G1), AIT was undertaken for 5 months (40 professional AIT sessions performed two times per week in 50 minute sessions) and followed a specially developed program. The second control group (G2), did not attend any training sessions but received medical advice on how to maintain physical activity as outlined by JNC (Joint National Committee) hypertension guidelines. During the baseline visit and then at five months (final visit), both groups underwent testing for office BP (blood pressure), PWV and applanation tonometry indexes using the SphygmoCor® device and the Complior® device.
