Order exercise stress testing without imaging for patients with a low to intermediate probability of coronary artery disease (CAD), unless preexisting electrocardiographic (EKG) changes would render such a test nondiagnostic. Order stress testing with imaging for patients with preexisting EKG changes and/or a high probability of CAD. Do not use stress testing to screen asymptomatic patients for...
Objectives: The present study investigates the effectiveness of aerobic training interventions and training coping skills to reduce stress among firefighting staff. Method: The study was a semi-experimental and pre-test-post-test with control group. Sixty individuals were selected from among the volunteer firefighting staff in Tehran. They were randomly assigned to two experimental groups ...
Background: The equations predicting maximal oxygen uptake (VO2max or peak) presently in use in cardiopulmonary exercise testing (CPET) softwares in Brazil have not been adequately validated. These equations are very important for the diagnostic capacity of this method. Objective: Build and validate a Brazilian Equation (BE) for prediction of VO2peak in comparison to the equation cited by Jones...
OBJECTIVES The aim of this study was to determine whether changes in oxygen efficiency occur with aging or exercise training in healthy young and older subjects. BACKGROUND Exercise capacity declines with age and improves with exercise training. Whether changes in oxygen efficiency, defined as the oxygen cost per unit work, contributes to the effects of aging or training has not yet been defi...
Introduction: This study aimed to investigate the effect of garlic supplementation on oxidative stress markers (AST, ALT, LDH, and CPK) following progressive resistance exercise. Methods: This research was a double-blind clinical trial with repeated measures. After obtaining informed consent, 20 sedentary females participated in this study (age: 23.15±2.65 years, BMI: 22.93±1.25 kg.m2). They w...
OBJECTIVE To investigate whether physiological cardiac reserve can be measured in man without invasive procedures and whether it is a major determinant of exercise capacity. DESIGN Development of method of measurement and an observational study. SETTING A regional cardiothoracic centre. SUBJECTS 70 subjects with a wide range of cardiac function, from heart failure patients to athletes. ...
BACKGROUND Exercise training is known to improve the shortness of breath experienced by patients with heart disease when the ventilatory pattern becomes abnormal during exercise. However, the precise relationship between breathing patterns and the effect of exercise training has not been elucidated to date. We evaluated the relationship between the effect of exercise training on exercise tolera...
