Patients with chronic thromboembolic pulmonary hypertension (CTEPH), despite successful pulmonary endarterectomy (PEA), can continue to suffer from a limitation in exercise capacity. The objective of this study was to assess whether pulmonary arterial compliance is a predictor of exercise capacity after PEA. Right heart haemodynamics, treadmill incremental exercise test, spirometry, carbon mono...

Background: Aasthma due to causing disruption in the work of breathing and obstruction of the pulmonary tract creates the physical restrictions in the social, emotional and psychological, aspects and performing daily life activities, hence the present study is conducted to determine the impact of a period of selected activity on some spirometry parameters of children from 5 to 10 years old suff...

PURPOSE/OBJECTIVES To test the effects of aerobic and resistance exercise on changes in bone mineral density (BMD) in women newly diagnosed with stage I-III breast cancer receiving chemotherapy. DESIGN Randomized clinical trial. SETTING Two National Cancer Institute-designated cancer centers in metropolitan areas. SAMPLE 66 women with stage I-III breast cancer beginning adjuvant chemother...

OBJECTIVE To determine whether adolescents with type 1 diabetes have left ventricular functional changes at rest and during acute exercise and whether these changes are affected by metabolic control and diabetes duration. RESEARCH DESIGN AND METHODS The study evaluated 53 adolescents with type 1 diabetes and 22 control adolescents. Baseline data included peak exercise capacity and body compos...

INTRODUCTION AND OBJECTIVES Using gadolinium-enhanced cardiovascular magnetic resonance, it is possible to evaluate the presence of myocardial fibrosis in hypertrophic cardiomyopathy. Classical disease markers are weak predictors of functional disability in affected patients. Our objective was to study the relationship between the degree of myocardial fibrosis observed by cardiac magnetic reson...

Exercise induces an increase in GLUT4 in skeletal muscle with a proportional increase in glucose transport capacity. This adaptation results in enhanced glycogen accumulation, i.e., "supercompensation," in response to carbohydrate feeding after glycogen-depleting exercise. The increase in GLUT4 reverses within 40 h after exercise in carbohydrate-fed rats. The purpose of this study was to determ...

QUESTION Does a new positive expiratory pressure device (conical-PEP) decrease lung hyperinflation during exercise in patients with chronic obstructive pulmonary disease compared to normal breathing? Does it increase the duration of exercise? DESIGN A randomised, cross-over trial with concealed allocation. PARTICIPANTS Thirteen patients with moderate to severe chronic obstructive pulmonary ...

Maximal exercise vasodilatation results from the balance between vasoconstricting and vasodilating signals combined with the vascular reactivity to these signals. During maximal exercise with a small muscle mass the skeletal muscle vascular bed is fully vasodilated. During maximal whole body exercise, however, vasodilatation is restrained by the sympathetic system. This is necessary to avoid hy...

Results: Maximum oxygen uptake was significantly correlated with 6 minute walking distance. Both exercise tests were correlated with pulmonary function tests. However, maximum exercise capacity was more closely correlated with measures of lung function than 6MWT. Both tests were significantly correlated with static lung volumes. Inspiratory capacity (IC) was significantly correlated with 6MWT a...

OBJECTIVE To investigate the effect of self exercise in cardiac rehabilitation on cardiopulmonary exercise capacity for selected patients with coronary artery disease. METHOD The subjects of this study were patients who received percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery and who participated in a cardiac rehabilitation program. The supervised exerc...
