The aims of the study were to determine whether heart rate variability (HRV) measured at rest and during exercise could be altered by an exercise training programme designed to increase walking performance in patients with peripheral arterial disease. Forty-four volunteers were randomised into 12 weeks of either: supervised walking training twice weekly for 30 min at 75% VO2peak (SU), home-base...
AIMS Recent studies have evaluated the diagnostic accuracy and predictive value of dobutamine echocardiography without considering the additional information implied by the magnitude of induced wall motion abnormalities. We sought to evaluate the positive predictive value of dobutamine echocardiography for coronary artery disease from the extent and severity of the induced wall motion abnormali...
OBJECTIVE To determine the relation between functional capacity and heart rate response to exercise in patients with atrial fibrillation. SUBJECTS 73 consecutive patients with chronic atrial fibrillation. MAIN OUTCOME MEASURES Relation between functional capacity, measured as peak oxygen consumption (peak VO2; ml/min/kg), and heart rate at all stages of exercise in univariate and multivaria...
[Purpose] The aim of this study was to compare the body composition, heart rate variability, and aerobic and anaerobic performance between competitive cyclists and triathletes. [Subjects] Six cyclists and eight triathletes with experience in competitions voluntarily participated in this study. [Methods] The subjects' body composition was measured with an anthropometric tape and skinfold caliper...
