OBJECTIVES The present study was performed to investigate 1) whether aerobic exercise training prior to myocardial infarction would prevent cardiac dysfunction and structural deterioration and 2) whether the potential cardiac benefits of aerobic exercise training would be associated with preserved morphological and contractile properties of cardiomyocytes in post-infarct remodeled myocardium. ...

To the Editor: We thank Kurtoglu and colleagues for their interest in our article, “Aerobic Exercise Training Decreases Plasma Asymmetric Dimethylarginine Concentrations with Increase in Arterial Compliance in Postmenopausal Women.”1 We demonstrated that 12 weeks of aerobic exercise training decreased plasma asymmetric dimethylarginine (ADMA) concentrations in postmenopausal women. In their Let...

AIM The aim of this study was to provide a more extensive evaluation of the effects of chronic aerobic exercise on various components of the insulin signalling cascade in normal rodent skeletal muscle because of the limited body of literature that exists in this area of investigation. METHODS Male Sprague-Dawley rats were assigned to either control (n = 7) or chronic aerobic exercise (n = 7) ...

OBJECTIVE To assess the influence of 2 single exercise sessions on blood pressure in sedentary normotensive individuals: one of resistive exercise training (circuit weight training) and the other of aerobic exercise training. METHODS Using ambulatory blood pressure monitoring, this study assessed 25 individuals as follows: in a controlled situation at rest (ABPM 1); after resistive exercise t...

We tested whether supplementation with L-arginine can augment aerobic capacity, particularly in conditions where endothelium-derived nitric oxide (EDNO) activity is reduced. Eight-week-old wild-type (E(+)) and apolipoprotein E-deficient mice (E(-)) were divided into six groups; two groups (LE(+) and LE(-)) were given L-arginine (6% in drinking water), two were given D-arginine (DE(+) and DE(-))...

Introduction: The aim of this study was to evaluate the effects of aerobic exercise and pomegranate extract on antioxidant markers in women postmenopausal with type 2 diabetes. Methods: The statistical population of this study was the postmenopausal diabetic women of Babol City, North of Iran, who were referred to the Diabetes Association of the city. Among them, 33 subjects were selected rand...

AIM To examine the effects of obesity phenotype on abdominal fat responses to regular aerobic exercise. METHOD Fifty-seven obese men aged 34-70 years were divided into two groups based on baseline intra-abdominal fat (IF) area measured by computerized tomography: moderate (<200 cm(2)) IF (MIF; n=33, age: 52.9+/-10.6 [SD] yr, body mass index [BMI]: 29.2+/-3.1 kg/m(2)) or high (>or=200 cm(2)) I...
