Biomarkers of Oxidative Stress, Inflammation, and Brain Damage in Mexican Women over 60 Years of Age with Obesity Open
Background: Obesity and aging are risk factors for chronic degenerative diseases that favor neuroinflammation leading to cognitive and motor impairment. Mexico ranks second in obesity worldwide, being more prevalent in the female populatio…

Hemodynamics and cerebral oxygenation during acute exercise in moderate normobaric hypoxia and with concurrent cognitive task in young healthy males Open
The present investigation aimed to study the cardiovascular responses and the cerebral oxygenation (Cox) during exercise in acute hypoxia and with contemporary mental stress. Fifteen physically active, healthy males (age 29.0 ± 5.9 years) …

Executive Functions and Mood States in Athletes Performing Exercise Under Hypoxia Open
Hypoxia can impair cognitive performance, whereas exercise can enhance it. The effects of hypoxia on cognitive performance during exercise appear to be moderated by exercise duration and intensity and by severity and duration of hypoxia an…

Acute Exercise with Moderate Hypoxia Reduces Arterial Oxygen Saturation and Cerebral Oxygenation without Affecting Hemodynamics in Physically Active Males Open
Hemodynamic changes during exercise in acute hypoxia (AH) have not been completely elucidated. The present study aimed to investigate hemodynamics during an acute bout of mild, dynamic exercise during moderate normobaric AH. Twenty-two phy…

Systolic and Diastolic Functions After a Brief Acute Bout of Mild Exercise in Normobaric Hypoxia Open
Acute hypoxia (AH) is a challenge to the homeostasis of the cardiovascular system, especially during exercise. Research in this area is scarce. We aimed to ascertain whether echocardiographic, Doppler, and tissue Doppler measures were able…
View article: Effect of Combined Mental Task and Metaboreflex Activation on Hemodynamics and Cerebral Oxygenation in Patients With Metabolic Syndrome
Effect of Combined Mental Task and Metaboreflex Activation on Hemodynamics and Cerebral Oxygenation in Patients With Metabolic Syndrome Open
Objective: The hemodynamic response to muscle metaboreflex has been reported to be significantly altered by metabolic syndrome (MS), with exaggerated systemic vascular resistance (SVR) increments and reduced cardiac output (CO) in comparis…

Diabetic Cardiomyopathy and Ischemic Heart Disease: Prevention and Therapy by Exercise and Conditioning Open
Metabolic syndrome, diabetes, and ischemic heart disease are among the leading causes of death and disability in Western countries. Diabetic cardiomyopathy is responsible for the most severe signs and symptoms. An important strategy for re…

METABOREFLEX ACTIVITY IN HEART FAILURE WITH REDUCED AND PRESERVED EJECTION FRACTION Open
Introduction Chronic heart failure (CHF) is a syndrome characterized by reduced cardiac output (CO) unable to meet metabolic demands of active tissues. The reduced (HFrEF) or preserved ejection fraction (HFpEF) identifies the systolic and …

Hemodynamic abnormalities during muscle metaboreflex activation in patients with type 2 diabetes mellitus Open
Metaboreflex is a reflex triggered during exercise or postexercise muscle ischemia (PEMI) by metaboreceptor stimulation. Typical features of metaboreflex are increased cardiac output (CO) and blood pressure. Patients suffering from metabol…
View article: Blood Flow Restriction Training Reduces Blood Pressure During Exercise Without Affecting Metaboreflex Activity
Blood Flow Restriction Training Reduces Blood Pressure During Exercise Without Affecting Metaboreflex Activity Open
Objective: Blood flow restriction training (BFRT) has been proposed to induce muscle hypertrophy, but its safety remains controversial as it may increase mean arterial pressure (MAP) due to muscle metaboreflex activation. However, BFR trai…

Hemodynamic Responses during Enduro-Motorcycling Performance Open
Much of the information available in the literature on physiological responses during Enduro motorcycling is related to heart rate (HR) and blood lactate (BLa). The aim of this work was to investigate the hemodynamic changes that occur dur…

Mean Blood Pressure Assessment during Post-Exercise: Result from Two Different Methods of Calculation. Open
At rest the proportion between systolic and diastolic periods of the cardiac cycle is about 1/3 and 2/3 respectively. Therefore, mean blood pressure (MBP) is usually calculated with a standard formula (SF) as follows: MBP = diastolic blood…

Consequences of Type 1 and 2 Diabetes Mellitus on the Cardiovascular Regulation During Exercise: A Brief Review Open
Hemodynamic dysfunctions may develop in both type 1 and 2 DM during exercise. However, these cardiovascular dys-regulations are different between the two kinds of diabetes.

Ischemic preconditioning reduces hemodynamic response during metaboreflex activation Open
Ischemic preconditioning (IP) has been shown to improve exercise performance and to delay fatigue. However, the precise mechanisms through which IP operates remain elusive. It has been hypothesized that IP lowers the sensation of fatigue b…
