Cardiovascular and cerebral hemodynamics during exercise and recovery in obese individuals as a function of their fitness status

et al. 2017

The aim of this study was to compare cardiovascular hemodynamics and cerebral oxygenation/perfusion (COP) during and after maximal incremental exercise in obese individuals according to their aerobic fitness versus age‐matched healthy controls (AMHC). Fifty‐four middle–aged obese (OB) and 16 AMHC were recruited. Maximal cardiopulmonary function (gas exchange analysis), cardiac hemodynamics (impedance cardiography), and left frontal COP (near‐infrared spectroscopy: NIRS) were measured continuously during a maximal incremental ergocycle test. During recovery, reoxygenation/perfusion rate (ROPR: oxyhemoglobin: ΔO2Hb, deoxyhemoglobin: ΔHHb and total hemoglobin: ΔtHb; with NIRS) was also measured. Obese participants (OB, n = 54) were divided into two groups according to the median V˙O2 peak: the low‐fit obese (LF‐OB, n = 27) and the high‐fit obese (HF‐OB, n = 27). During exercise, end tidal pressure of CO 2 (PETCO 2), and COP (ΔO2Hb, ΔHHb and ΔtHb) did not differ between groups (OB, LF‐OB, HF‐OB, AMHC). During recovery, PETCO 2 and ROPR (ΔO2Hb, ΔHHb and ΔtHb) were similar between the groups (OB, LF‐OB, HF‐OB, AMHC). During exercise and recovery, cardiac index was lower (P < 0.05) in LF‐OB versus the other two groups (HF‐OB, AMHC). As well, systolic blood pressure was higher during exercise in the OB, LF‐OB and HF‐OB groups versus AMHC (P < 0.05). When compared to AMHC, obese individuals (OB, LF‐OB, HF‐OB) have a similar cerebral vasoreactivity by CO 2 and cerebral hemodynamics during exercise and recovery, but a higher systolic blood pressure during exercise. Higher fitness in obese subjects (HF‐OB) seems to preserve their cardiopulmonary and cardiac function during exercise and recovery.

“…Sin embargo, esta adaptación no solo es importante a nivel muscular, sino que se correlaciona positivamente y de forma directa con factores de riesgo cardiovasculares, como la cantidad de oxígeno requerido para la realización correcta de la actividad, la frecuencia cardiaca, el volumen sistólico y la presión arterial, entre otras. (Taylor, Wiles, Coleman, Sharma y O'driscoll, 2017;Vella, Paul y Bader, 2012).…”

Actualmente nos encontramos ante una situación preocupante debido a que los problemas cardiovasculares cada vez están más presentes afectando a un elevado porcentaje de la población, los cuales están llegando a desencadenar enfermedades que ponen en riesgo la salud de la población, provocados mayoritariamente a causa de la adquisición de hábitos no sanos o sedentarios, los cuales se están desarrollando cada vez más en edades tempranas. Por ello, en este estudio se ha llevado a cabo una revisión sistemática que aborda estudios científicos pre-experimentales o cuasi-experimentales, los cuales han aplicado intervenciones utilizando la práctica de actividad físico deportiva como medio para mejorar la frecuencia cardiaca, el volumen sistólico, el VO2 máximo y la condición física de los sujetos. Los resultados de las diversas investigaciones han puesto de relieve que la realización regular y continuada de ejercicio adaptada a las características individuales de cada uno de los participantes reporta beneficios mejorando la salud y las cualidades físicas.

“…Returning to Mexico, a recent study in obese Hispanic Mexicans reported a direct link between obesity and diminished cardiac response to maximal exercise, contributing to explain the known overall mortality risk in the obese (Vella et al 2012). Nevertheless, as long as a certain health literacy in the population is not reached, the known associations cannot truly be translated into the adaptation of lifestyle.…”

Cardiac response to exercise in normal‐weight and obese, Hispanic men and women: implications for exercise prescription

Abstract: Our findings suggest that although Q index and SV index were higher in obese, young adults, EF and a-vO(2) index were significantly lower when compared to matched, normal-weight adults.
