The purpose of the investigation was to study plasma adiponectin response to a single exercise session in male rowers. Eight college level, single scull rowers (VO2max: 5.01+/-0.43 l.min-1; age: 21.5+/-4.5 yrs; height: 184.9+/-5.0 cm; body mass: 78.5+/-8.4 kg; body fat: 11.8+/-1.2%) participated in this study. Venous blood samples were obtained before,(More)
The use of the heart rate turn point (HRTP) to set target heart rate (THR) for prolonged rowing ergometer (E) and single scull rowing (R) was evaluated. Ten trained subjects (age 21.3 +/- 4.0 yrs; VO (2max) 4.77 +/- 0.62 l . min-1) performed incremental exercise tests and 30-min prolonged E and R. Expired air and heart rate (HR) were measured continuously.(More)
Determination of an 'anaerobic threshold' plays an important role in the appreciation of an incremental cardiopulmonary exercise test and describes prominent changes of blood lactate accumulation with increasing workload. Two lactate thresholds are discerned during cardiopulmonary exercise testing and used for physical fitness estimation or training(More)
BACKGROUND Previous studies have demonstrated that in patients with coronary artery disease (CAD) upward deflection of the heart rate (HR) performance curve can be observed and that this upward deflection and the degree of the deflection are correlated with a diminished stress dependent left ventricular function. Magnesium supplementation improves(More)
BACKGROUND The Indian plant root Salacia reticulata, which is rich in alpha-glucosidase inhibitors, is used for metabolic disorders in Ayurvedic medicine. Vitamin D₃ is also used in the treatment of some metabolic diseases. Our goal was to determine its potential effect for humans with obesity. MATERIAL In a randomized open-label study, we investigated 40(More)
PURPOSE Numerous investigations have reported changes in metabolic and cardiorespiratory responses associated with the menstrual cycle. We examined whether variables commonly used in exercise testing are influenced by menstrual cycle phases. METHODS Nineteen eumenorrheic women performed two incremental tests to voluntary exhaustion on a cycle ergometer(More)
UNLABELLED The percent of maximal heart rate (%HRmax) model is widely used to determine training intensities in healthy subjects and patients when prescribing training intensities in these groups of subjects. PURPOSE The aim of the study was to investigate the influence of the time course of the heart rate performance curve (HRPC) on the accuracy of(More)
PURPOSE This study aimed to evaluate cardiorespiratory and hemodynamic responses during 24 h of continuous cycle ergometry in ultraendurance athletes. METHODS Eight males (mean ± SD; age = 39 ± 8 yr, height = 179 ± 7 cm, body weight [Wt] = 77.1 ± 6.0 kg) were monitored during 24 h at a constant workload,∼25% below the first lactate turn point at 162 ± 23(More)
BACKGROUND The goal of cardiac rehabilitation programs is not only to prolong life but also to improve physical functioning, symptoms, well-being, and health-related quality of life (HRQL). The aim of this study was to document the long-term effect of a 1-month inpatient cardiac rehabilitation intervention on HRQL in Austria. METHODS Patients (N = 487,(More)
Two female patients with pulmonary arterial hypertension and a permanently implanted hemodynamic monitor changed treatment from inhaled iloprost to oral bosentan. The hemodynamic changes were seen very early after the first dose of bosentan and there was no need to re-establish inhaled iloprost.
