Exercise testing in healthy haemodialysis patients
… of regular haemodialysis patients to dynamic exercise. A systematic study of exercise capacity and the underlying mechanisms is of particular importance because these patients are encouraged to return to as normal a way of life as possible. Accordingly, a select group of healthy young male …

The effects of coronary heart disease, beta-blockade medications and stage duration on graded exercise testing
… impairments on cardiorespiratory dynamics during exercise testing. Therefore, this study was conducted to examine the exercise responses of 26 subjects (ages 37-66 years) to a graded exercise test. Subjects were divided into three groups based on clinical status: apparently healthy (AH; N=8); …

Prediction of oxygen consumption during exercise testing in apparently healthy subjects and coronary artery disease patients
… minute VO₂ responses at maximal and submaximal exercise for either group. At peak exercise, the AH group was significantly (P≤.05) different from the CAD group when compared for heart rate (164±2.6 vs 140±4.8 bts•min⁻¹ ), V̇O₂ (33.3±1.1 vs 26.7±2.3 ml•kg⁻¹•min⁻¹), and total treadmill time …

The Effects of Obstructive Sleep Apnea Syndrome on Cardiovascular Function with Exercise Testing in Young Adult Males
… new methods for assessing OSAS risk. The exercise test has been used effectively as a diagnostic and prognostic tool for those at high risk for cardiovascular disease and hypertension. Research into the cardiopulmonary responses to exercise testing in young adult men with OSAS has not been …

The Relationship of Resting Cardiopulmonary Function to Peak and Submaximal Cardiopulmonary Exercise Testing in Older Adults with Heart Failure
Background: Heart failure (HF) is a challenging disease that affects more than five million people, half of whom are at least 75 years old. Peak oxygen consumption (VO2peak), the minute ventilation/carbon dioxide production (VE/VCO2) slope, and the 6MWT are powerful prognostic indicators of …

The relationship between markers of disease severity in obstructive sleep apnea patients and hemodynamic and respiratory function during graded exercise testing
… of hemodynamic measures to be used during exercise testing, a study was conducted on the acetylene single-breath cardiac output (Qc) technique in 15 healthy subjects. This was completed in order to establish reliability of exercise Qc and total peripheral resistance (TPR), these responses …

Reproducibility of a continuous-wave Doppler ultrasound system for assessment of ascending aortic blood flow responses during graded exercise testing with healthy individuals
… (SVI) were taken at each stage of a graded exercise treadmill test on two separate days with 30 physically active adult males. Signals were measured (Quinton Exerdop) for all cardiac cycles in the 3rd minute of each stage using a hand-held probe positioned at the suprasternal notch. A …

Functional electrical stimulation (FES) leg cycling exercise in paraplegia: a pilot study for the definition and assessment of exercise testing protocols and efficacy of exercise
… feedback system for accurate control of exercise workrate and cadence has been employed in this study. This experimental setup allowed the imposition of arbitrary workrate profiles with high precision and provided the potential for highly-sensitive exercise testing. One aim of the work …

Inclusive and adaptive assessment of cardiorespiratory fitness for population health research
… and safety considerations associated with exercise testing that often lead to selection bias and distorted health associations. It presents the development, validation, and application of a comprehensive suite of fitness assessment methods that are applicable in diverse population groups, …

Control strategies for functional electrical stimulation induced cycling
… of years to allow Spinal Cord Injured persons to exercise. Standard able bodied exercise tests are adapted and applied to paraplegic cyclists. A modified recumbent tricycle is instrumentated with an electric motor and sensors to measure cadence and the power produced by the cyclist at the crank. …

Aspects of respiratory function during exercise in the thoroughbred horse in health and disease
… respiratory load on the lungs many fold during exercise, hence low-grade respiratory disease is difficult to detect at rest, although of vital importance during heavy exercise. Diagnostic exercise testing is, therefore, of great interest and this thesis describes its application to the …

Exercise capacity with special reference to type 2 diabetes
… the thesis to represent a wider population. The exercise capacity was studied in one group of healthy sedentary middle aged men with normal glucose tolerance in study I and II. In a group of elderly men with normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and with type 2 diabetes …

The pathophysiology of heart failure with preserved ejection fraction
… ratio. Data acquired during semi-supine cycling exercise indicates that patients with HfpEF had a dynamic impairment of LV active relaxation. In addition, ventricular-vascular coupling ratio was unchanged during exercise in HfpEF patients in contrast to healthy controls where the ratio fell …

Unexplained Exercise Intolerance and Dyspnea in Long COVID
… by persistent dyspnea, fatigue, and exercise intolerance despite normal cardiopulmonary findings. This study examined whether peripheral impairments—specifically respiratory muscle dysfunction and endothelial impairment—contribute to these symptoms. Thirty COVID-19 convalescent adults …

The Effect of Total Work Performed During Acute Heavy Resistance Exercise on Circulating Lymphocytes in Untrained Men
… a biphasic response to acute intense resistance exercise. Exercise volume (i.e. total work) has been shown to have an immunomodulatory effect. This study evaluates the effect of total work performed during an intense resistance exercise protocol on lymphocyte concentrations in the circulation. …

The effect of exercise training on physical fitness in type 2 diabetes mellitus
We compared the effects of different exercise modes on cardiorespiratory fitness and muscular strength as well as the rate of strength development in individuals with T2DM. 251 participants in the DARE trial were randomly allocated to aerobic training (A), resistance training (R), combined training …

The long-term respiratory health effects of the herbicide, paraquat, among Western Cape workers
… radiographs performed. Oxygen desaturation on exercise testing was by oximetry during a modified stage one exercise test. Results: No association was found between long-term paraquat exposure and reported symptoms, spirometry (FVC, FEVl, FEVl/FVC) and gas transfer (TLco and Kco) or chest …

The relative roles of portal hypertension and of cirrhosis in the pathogenesis of pulmonary lesions associated with chronic liver disease
… to clarify this. Pulmonary function, including exercise testing, was evaluated in two groups of patients, 11 with portal hypertension due to cirrhosis and 10 with extrahepatic portal vein thrombosis and normal liver histology. Carbon monoxide gas transfer (TLCOsb) was less than 75% of predicted …
