introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

this study sought to compare the clinical features and outcome of a first acute myocardial infarction (ami) with onset of symptoms during or within 30 minutes of exercise, at rest and in bed. information collected using a standard questionnaire was used to relate activity at the onset of symptoms and in-hospital outcome in 500 consecutive patients admitted to our heart center with a first ami b...

Previous studies have shown changes in brain activity as a result of exercise; however, few studies have examined changes during exercise. The purpose of this study was to examine brain activity during a graded exercise test. Twenty male participants performed a graded exercise test on a recumbent cycle ergometer. Exercise intensity was set initially at 50W and was increased by 50W every 2 minu...

Rheumatoid arthritis (RA) is an autoimmune disease, which not only affects the joints but can also impact on general well-being and risk for cardiovascular disease. Regular physical activity and exercise in patients with RA have numerous health benefits. Nevertheless, the majority of patients with RA are physically inactive. This indicates that people with RA might experience additional or more...

Metab. 40): E390–E394, 1999.—This study examined the effects of acute exercise on skeletal muscle nitric oxide synthase (NOS) activity. Female Sprague-Dawley rats were divided into three groups: control, exercise...

conclusions we suggest that regular aerobic exercise can favorably alter the inflammatory profile, which is a known risk factor in breast cancer development, in postmenopausal women. patients and methods this study was a randomized controlled trial. we randomly assigned 41 postmenopausal, sedentary women aged 50 to 74 to either an exercise or a control group. the intervention involved facility-...
