Aerobic and anaerobic exercise tolerance in the heat : effect of acclimatization
The effect of heat acclimatization on aerobic exercise tolerance in the heat, and on subsequent anaerobic exercise performance was investigated. Ten male subjects were acclimatized by exercising 90 minutes per day for eight days in the heat (39.7 C db, 31.0% RH) on a bicycle ergometer at a workload …

Factors limiting the exercise tolerance of patients with end-stage renal failure undergoing maintenance haemodialysis
Exercise tolerance, measured as peak oxygen consumption (VO₂ peak), is very low in patients with end-stage renal failure undergoing maintenance haemodialysis. Due to their associated anaemia and low peak heart rates during maximal exercise it has been argued that the reduced blood oxygen carrying …

Exercise tolerance and skeletal muscle structure and function in patients with chronic obstructive pulminary disease
Exercise intolerance is well documented in patients with chronic obstructive pulmonary disease (COPD). Historically, this exercise intolerance has been attributed to the central factors of lung damage and subsequent heart failure. However, recent evidence suggests that (i) patients with cardiac and …

Exercise tolerance and skeletal muscle structure and function in patients with severe chronic heart failure
Fatigue and exercise intolerance are common symptoms experienced by patients with chronic heart failure (CHF). Historically it has been argued that central cardiopulmonary factors including pulmonary congestion and reduced lung compliance cause dyspnoea that limits the exercise tolerance of such …

The Effect of Nitrate Supplementation on Exercise Tolerance and Performance: A Systematic Review and Meta-Analysis
… overall efficacy of nitrate supplementation on exercise tolerance and performance by meta-analysis. Studies were eligible for inclusion if they met the following criteria: 1) were an experimental trial published in an English peer-reviewed journal; 2) compared the effects of inorganic nitrate …

Central and peripheral fatigue in response to the acute and chronic metabolic demand: implications for exercise tolerance
Fatigue and the associated exercise limitation has wide reaching human performance and health implications, however the mechanisms are poorly understood. Muscle fatigue during exercise originates from a combination of peripheral and central processes, and their interaction, which are influenced by …

Chronotropic Incompetence in Patients with Heart Failure and a Preserved Ejection Fraction: Prevalence and Impact on Exercise Tolerance
… An appropriate heart rate (HR) response to exercise is important, as it represents a key determinant of oxygen consumption (VO2). Furthermore the inability of HR to increase sufficiently, chronotropic incompetence (CI), has important functional and prognostic implications in heart failure …

Relationship of exercise tolerance, exercise intensity, and physical performance in frail elderly individuals residing in a long-term care facility
… minutes of walking and during a low level seated exercise test. Ratings of perceived exertion were determined following the exercise test. Physical performance was determined by timed chair rise and sit, challenged standing, 8-foot walk speed, and 5- minute walk distance. The subjects were tested …

Obstructive Sleep Apnea Risk in Abdominal Aortic Aneurysm Disease Patients: Associations with Physical Activity Status, Metabolic Syndrome, and Exercise Tolerance
… activity (PA), metabolic syndrome (MetSyn), and exercise responses to cardiopulmonary exercise testing (CPET) in elderly patients with AAA disease. Methods: Elderly patients (n=326 for Studies 1 and 2; n=114 for Study 3) newly diagnosed with small AAAs (aortic diameter "2.5 and < 5.5 cm) were …

Using the stress electrocardiograph (ECG) exercise tolerance test (ETT) in an emergency department (ED) to assess low-risk patients with suspected acute coronary syndrome (ACS)
This study examines the outcomes of a group of low-risk patients with uncertain diagnosis, who were seen at a rural health facility. A stress ECG was performed on the patients within 24 hours of the onset of pain, with those with negative tests subsequently being discharged.

Skeletal muscle structure and metabolism in chronic heart failure
Chronic heart failure (CHF) patients have poor exercise tolerance, which does not correlate with impaired central function. Consequently factors other than impaired cardiac function must contribute to the exercise intolerance. Maladaptations in skeletal muscle appear to be a likely reason for the …

Defining a set of patient attributes that predict exercise performance outcome following an exercise training program in a population of coronary artery disease patients
… the utility of baseline clinical and graded exercise test (GXT) variables in predicting exercise training outcome in cardiac rehabilitation patients. Data were extracted from the records of 60 cardiac patients who had participated in a community-based exercise program for 5-9 months. Two …

The integration of neuromuscular, perceptual, and cardiorespiratory fatigue responses is modulated by high intensity interval training characteristics and blood flow restriction in males and females
… interspersed by recovery phases. This popular exercise paradigm has been hypothesized to mitigate metabolic by-product accumulation and to result in a disconnect between the work completed and the neuromuscular, perceptual, and cardiovascular responses to exercises performed in the severe …

The effect of a community based pulmonary rehabilitation programme on the quality of life of patients with pulmonary tuberculosis
… whether a community based rehabilitation exercise programme had an effect on pulmonary function, exercise tolerance and Health Related Quality of Life (HRQoL) in patients diagnosed with Pulmonary Tuberculosis (PTB). The prevalence of PTB in South Africa is one of the highest in the African …

Skeletal muscle mitochondrial capacity and metabolism in lung transplant patients and resistance trained subjects
Lung transplant (LTx) recipients have poor exercise tolerance, which persists in spite of the restoration of near normal lung function. This suggests that the exercise limitation is related to defects in skeletal muscle. Firstly, mitochondrial function and metabolism in resting skeletal muscle were …

The effect of environmental temperature on exercise metabolism
… capacity of individuals is diminished during exercise in the heat, such that heat stress leads to an earlier onset of fatigue. Chronic exposure to hot conditions, however, may reverse this process. Exercise in cool conditions can either improve or reduce exercise tolerance depending on the …

Mechanisms of impaired red blood cell ATP release in older adults: implications for altered vascular control with age
… age-associated declines in functional capacity, exercise tolerance, and overall quality of life. Thus, understanding the mechanisms of the age-related impairments in vascular control and identifying potential therapeutic targets holds significant potential for reducing the healthcare burden …

The final part of the main study explored the effects of the exercise programme in a single blinded randomised controlled trial. In …

Cardiovascular and respiratory reflex control systems in the regulation of pulmonary blood flow and ventilation during exercise
… of pulmonary blood flow and ventilation during exercise is mediated by numerous factors, yet the role of certain cardiovascular and pulmonary reflex control systems is unknown. Therefore this thesis investigated the pulmonary vascular response to the activation of the muscle metaboreflex alone, …
