Abstract
PurposeThe aim of this study was to verify if the association of hypertension and diabetes mellitus could lead to the differences on cardiorespiratory fitness and lipid profile in older adults. Methods40 older adults were divided into two groups: Hypertensive (HTN) and Hypertensive-diabetic (HTN + T2DM). Maximum exercise test on a treadmill was conducted. Lipid profiles assessment was conducted before and after exercise. The cardiorespiratory fitness (CRF) variables were peak oxygen consumption (VO2peak), time to reach peak oxygen consumption (TVO2peak), carbon dioxide ventilatory equivalent (VE/VCO2) and carbon dioxide production (VCO2). To test intergroup and intragroup analyses independent and paired t-tests were used before and after acute exercise. Multiple linear regression was performed to test the influence of coexistence of HTN and T2DM on CRF. ResultsCRF measures such as VO2peak (β = -3.90), VCO2 (β = -3.87) and TVO2peak (β= -115.79) were significantly (p-value <0.01) lower in HTN + T2DM group. After acute exercise, there was an increase in the levels of lipid profile variables, however without differences between groups. ConclusionHTN + T2DM older adults had poorer CRF. Acute changes in lipemia were similar in both groups.
