Impaired ventricular filling limits cardiac reserve during submaximal exercise in people with type 2 diabetes
BACKGROUND Attenuated increases in ventricular stroke volume during exercise are common in type 2 diabetes and contribute to reduced aerobic capacity. The purpose of this study was to determine whether impaired ventricular filling or reduced systolic ejection were responsible for the attenuated stroke volume reserve in people with uncomplicated type 2 diabetes. METHODS Peak aerobic capacity a...
متن کاملNeural control of force output during maximal and submaximal exercise.
A common belief in exercise physiology is that fatigue during exercise is caused by changes in skeletal muscle metabolism. This 'peripheral' fatigue results either from substrate depletion during submaximal exercise or metabolite accumulation during maximal exercise in the exercising muscles. However, if substrate depletion alone caused fatigue, intracellular ATP levels would decrease and lead ...
متن کاملMeasurement of cardiac output during exercise.
T here are a variety of reasons why the clinician would want to measure cardiac output. In the intensive care unit (ICU), life-threatening hypoperfu-sion states may be subject to manipulation. Outside the ICU, low cardiac output may limit the quality of life. A functional definition of heart failure is a cardiac output insufficient for metabolic needs. Implicit in this is the magnitude of these...
متن کاملReduced peripheral arterial blood flow with preserved cardiac output during submaximal bicycle exercise in elderly heart failure
BACKGROUND Older heart failure (HF) patients exhibit exercise intolerance during activities of daily living. We hypothesized that reduced lower extremity blood flow (LBF) due to reduced forward cardiac output would contribute to submaximal exercise intolerance in older HF patients. METHODS AND RESULTS Twelve HF patients both with preserved and reduced left ventricular ejection fraction (LVEF)...
متن کاملRelationship between impaired chronotropic response, cardiac output during exercise, and exercise tolerance in patients with chronic heart failure.
The present study was undertaken to investigate the relationship between the extent of impaired chronotropic response and cardiac output during exercise, and exercise tolerance in patients with chronic heart failure. The subjects consisted of 24 patients (mean 60.1 +/- 14.0 years) who had mild chronotropic incompetence. Cardiopulmonary exercise testing was performed in all patients, and heart r...
