Biomarker responses of cardiac oxidative stress to high intensity interval training in rats

Motriz (Online); 27 (), 2021
Abstract Aim: The present study aimed to verify the cardiac oxidative stress biomarker responses to high-intensity interval training (HIIT) in rats. Methods: Sixteen male Wistar rats weighing 250 to 300 g were equally divided into two groups (8 animals/group): sedentary control (SC) and trained group (...

Effect of combined physical exercise program on improving the functional capacity and the cardiac autonomic modulation of Chagas cardiomyopathy

Motriz (Online); 27 (), 2021
Abstract Aims: Patients with Chagas cardiomyopathy (ChC) could have a significant reduction in functional capacity (FC). This study aimed to report the effect of a 24-week combined physical exercise program on the FC of a patient with ChC. Methods: A woman, 44 years old, with positive serology for ChC ...

ABSTRACT Objective: To evaluate factors associated with the performance of children and adolescents with cystic fibrosis (CF) in the Modified Shuttle Test (MST) and compare it with healthy children and adolescents. Methods: This is a cross-sectional study, with children and adolescents divided into t...

Heart rate and cardiac autonomic responses to concomitant deep breathing, hand grip exercise, and circulatory occlusion in healthy young adult men and women

Biol. Res; 54 (), 2021
BACKGROUND: Deep breathing (DB) and handgrip (HG) exercise -with and without circulatory occlusion (OC) in muscle-, have been shown to have beneficial effects on cardiovascular function; however, the combination of these maneuvers on heart rate (HR) and cardiac sympathovagal balance have not been previou...

Effect of continuous positive airway pressure associated to exercise on the breathing pattern and heart rate variability of patients undergoing coronary artery bypass grafting surgery: a randomized controlled trial

Braz. j. med. biol. res; 54 (11), 2021
Continuous positive airway pressure (CPAP) has been used to improve gas exchange and diaphragmatic function, among others benefits. Moreover, it can be used to increase exercise tolerance and positively influence ventilatory function and breathing pattern (BP) during exercise. However, there is no inform...

Effects of exercise training on autonomic modulation and mood symptoms in patients with obstructive sleep apnea

Braz. j. med. biol. res; 54 (5), 2021
We evaluated the effects of exercise training (ET) on the profile of mood states (POMS), heart rate variability, spontaneous baroreflex sensitivity (BRS), and sleep disturbance severity in patients with obstructive sleep apnea (OSA). Forty-four patients were randomized into 2 groups, 18 patients complete...

Effects of sympathectomy on myocardium remodeling and function

Clinics; 76 (), 2021
OBJECTIVES: To evaluate the effects of sympathectomy on the myocardium in an experimental model. METHODS: The study evaluated three groups of male Wistar rats: control (CT; n=15), left unilateral sympathectomy (UNI; n=15), and bilateral sympathectomy (BIL; n=31). Sympathectomy was performed by injection...
