Purpose This study aims to investigate the effects of acute cycling on blood pressure (BP), arterial function, and heart rate variability (HRV) in men living with HIV (MLHIV) using combined antiretroviral therapy (cART). Methods Twelve MLHIV (48.7 ± 9.2 years; 25.2 2.8 kg m –2 ) 13 healthy controls (41.2 9.9 26.3 2.9 performed a bout (ES) (intensity: 50% oxygen uptake reserve; duration: time achieve 150 kcal—MLHIV: 24.1 5.5 vs. controls: 23.1 3.0 min; p = 0.45), 20-min non-exercise session...

Reduced cardiac baroreflex sensitivity (cBRS) is an autonomic marker associated with a worse cardiovascular prognosis. Whether cBRS lowered in people living HIV (PLHIV) yet unclear, as well potential moderator effects of body mass index (BMI) or physical activity (PA) level. The present study aims to compare the spontaneous PLHIV vs. HIV-uninfected controls, and determine among relationship between PA Total, upward (cBRS+), downward (cBRS-) gains were assessed using sequential method from...

INTRODUCTION: The chronic effects of regular exposure to high acceleration levels (G-force) on the neuro-cardiovascular system are unclear. We compared mean arterial pressure (MAP) and cardiac autonomic modulation between nonpilots (NP) vs. military fighter (FP) transport (TP) pilots. Additionally, we correlated indices with cardiorespiratory fitness flight experience FP. METHODS: A total 21 FP, 8 TP, 20 NP performed a tilt test (TT), during which beat-to-beat blood heart rate were recorded....

A single session of aerobic exercise reduces blood pressure vs. pre-exercise, which is referred as postexercise hypotension (PEH). Changes in cardiac autonomic control and local vasodilatation contribute to PEH. HIV-infected patients present higher risk hypertension, endothelial dysfunction, may influence the However, this phenomenon has never been studied population. PURPOSE: To investigate effects acute upon systemic pressure, aortic modulation men living with HIV. METHODS: After...

Background People living with HIV (PLHIV) present impaired muscle metaboreflex, which may lead to exercise intolerance and increased cardiovascular risk. The metaboreflex adaptations training in these patients are unknown. study aims investigate the effects of a supervised multimodal on hemodynamic autonomic responses activation PLHIV. Methods design In this randomized clinical trial protocol, 42 PLHIV aged 30–50 years will be randomly assigned at ratio 1:1 into an intervention or control...

Introduction: There is no consensus regarding the chronic effects of regular exposure to high acceleration levels (G-force) on neuro-cardiovascular system.Objective: To compare cardiac autonomic modulation between non-pilots (NP) vs. military pilots - fighter (FP) and transport (TP). Additionally, we correlated indices with cardiorespiratory fitness flight experience FP.Methods: In this case-control study, 21 FP, 8 TP, 20 NP performed a tilt test (TT), during which beat-to-beat heart rate...
