Abstract

PIZANO, Alejandro; ECHEVERRI, Darío  and  MONTES, Félix R.. Effect of aerobic exercise in vascular stiffness in healthy population. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.3, pp.308-315.  Epub Feb 03, 2017. ISSN 0120-5633.  http://dx.doi.org/10.1016/j.rccar.2016.10.037.

Introduction:

A healthy lifestyle is key for cardiovascular health. There is controversy about beneficial vascular effects of physical exercise.

Motivation:

To assess the behaviour of vascular stiffness parametres in a healthy population group that practices routine aerobic exercise in comparison with another group of healthy population with a sedentary lifestyle.

Methods:

Study of 32 healthy individuals, paired according to age and gender: 12 men and 20 women (46.3±9.7 years old); the study assessed and compared arterial stiffness parametres (brachial systolic and diastolic blood pressure, brachial and central augmentation index, pulse wave velocity, central systolic and diastolic blood pressure and brachial and central pulse pressure).Measurements were conducted using the noninvasive oscillometric method Arteriograph® (TensioMed Budapest Hungary, Ltd.).

Results:

Arterial stiffness parametres were compared between both groups (16 active individuals vs. 16 sedentary ones), and the following significant differences were found: heart rate 53.25 ± 8.0 bpm vs. 59.75 ± 8.6 bpm (p = 0.034), brachial diastolic blood pressure of 70.0 (4.5) mmHg vs. 77.5 (8.3) mmHg (p = 0.043), central diastolic blood pressure of 70.0 (4.5) mmHg vs. 77.5 (8.1) mmHg (p = 0.043) and pulse wave velocity of 6.70 (1.1) m/s vs. 7.75 (1.1) m/s (p = 0.001).

Conclusions:

Routine aerobic exercise has a beneficial effect on vascular stiffness in a healthy population group, at the expense of a significant decrease in pulse wave velocity, heart rate and diastolic blood pressure (both brachial and central). These findings help explain the benefits of aerobic exercise on the cardiovascular system.
