Dyspnea is a subjective experience of breathing discomfort that can limit the ability and motivation to perform exercise or exertion. It is a common problem that affects specific groups of patients, such as, those suffering from chronic obstructive pulmonary disease, congestive heart failure, and interstitial lung disease, and in healthy ...

Abstract BACKGROUND: A growing body of research connects anxiety with poorer outcomes in COPD. However, more specific measures of dyspnea-related fear may be more closely related to critical processes involved in pulmonary rehabilitation (perception of dyspnea and avoidance of physical activity) and may have a predictive value for COPD outcome ...

Background and objective:  Increased pulmonary arterial pressure (PAP) usually coexists with impaired lung function in IPF. Data on the effect of pulmonary hypertension (PH) on cardiopulmonary responses during exercise in IPF patients is very limited. We sought to investigate the impact of PH on exercise capacity and the correlation between ...

Asthma, a chronic inflammatory disorder of the airways is associated with variable obstruction to the airways and is provoked by many triggers including exercise. The management of asthma is primarily pharmacological, but exercise, despite causing bronchoconstriction in almost all asthmatics, is an important adjunct to treatment. With adequate control of ...

Abstract BACKGROUND: There is considerable evidence that oxidative stress is increased in patients with COPD, although little information is available about its relation with the structural and functional alterations produced by COPD. We evaluate the relationship between 8-isoprostane in exhaled breath condensate (EBC) of stable COPD patients and the main ...

OBJECTIVES: The functional status of patients with non-small cell lung cancer (NSCLC) is often limited not only by cancer itself, but also by the different types of treatment and by comorbidities [eg, chronic obstructive pulmonary disease (COPD), congestive heart failure]. The aim of this study was to investigate the utility ...

It is well-known that pulmonary function is altered in patients with ankylosing spondilitis (AS) owing mainly to the restriction of chest expansion. In addition to musculoskeletal factors, development of pulmonary function abnormalities may also deteriorate exercise tolerance of the patients. The aim of this study was to examine the pulmonary ...

Eisenmenger syndrome, characterized by systemic-level pulmonary arterial resistance with resultant right-to-left shunt, is associated with low exercise capacity and hyperpnea at rest and exercise. Because ventilatory requirements are augmented by right-to-left shunting, we hypothesized that if pulmonary vasodilator treatment improved pulmonary perfusion in this condition, this would also improve ventilatory ...

The presence of obesity in COPD appears not to be a disadvantage with respect to dyspnea and weight-supported cycle exercise performance. We hypothesized that one explanation for this might be that the volume-reducing effects of obesity convey mechanical and respiratory muscle function advantages. Twelve obese chronic obstructive pulmonary disease (COPD) ...

Dyspnea is one of the main complaints of patients with cystic fibrosis (CF). Lung function at rest is not sufficient to explain dyspnea during exercise. Because inspiratory muscles are faced with an increased workload in advanced CF, we studied the impact of their strength and endurance on dyspnea and alveolar ...

The diaphragm was postulated to fatigue relatively early during exhaustive whole body exercise without further loss in contractility as exercise proceeds towards task failure. Diaphragmatic contractility was investigated prior/during/after exhaustive whole body exercise until task failure by using lung volume corrected twitch transdiaphragmatic pressure (TwPdi(c)) during magnetic phrenic nerve stimulation ...

ABSTRACT BACKGROUND: Obesity alters breathing mechanics during exercise. Weight loss improves lung function at rest, but the effect of weight loss, especially regional fat loss, on exercise breathing mechanics is unclear. We hypothesized that weight loss, especially a decrease in abdominal fat, would improve breathing mechanics during exercise due to ...

Excess ventilation during exercise with accompanying dyspnea is characteristic of chronic heart failure (CHF), and these patients often exhibit increased Ve relative to the Vco(2) compared with normal subjects. This can be measured in several ways, including using such variables as the slope of Ve versus Vco(2), the lowest ratio ...

Background: Eosinophils are the key inflammatory cells in asthma, and more and more evidence suggests their crucial role in exercise-induced bronchoconstriction (EIB). Eotaxin, as the most important chemotactic factor for eosinophils, plays an important role in the pathogenesis of asthma. Objectives: The aim of the study was to evaluate the ...

BACKGROUND: The pathogenesis of asthma involves both airway inflammation and an oxidant/antioxidant imbalance. It is demonstrated in asthmatic adults that exercise programmes improve lung function, a mechanism yet to be elucidated. The purpose of this study was to investigate the possible beneficial effects of physical exercise on antioxidant status in ...

Circulating leukocytes increase rapidly with exercise then quickly decrease when the exercise ends. We tested whether exercise acutely led to bidirectional interchange of leukocytes between the circulation and the lung, spleen, and active skeletal muscle. To accomplish this it was necessary to label a large number of immune cells (granulocytes, ...

Airway epithelium plays an important role in the asthma physiopathology. Aerobic exercise decreases Th2 response in murine models of allergic asthma, but its effects on the structure and activation of airway epithelium in asthma are unknown. BALB/c mice were divided into control, aerobic exercise, ovalbumin-sensitized and ovalbumin-sensitized plus aerobic exercise ...

Exercise-induced bronchoconstriction (EIB) is common; however, key aspects of its pathogenesis are still unclear. We investigated the feasibility of adapting an established animal model of asthma to investigate the earliest stages of EIB. The hypothesis was that a single exposure to a normally innocuous, and brief, exercise challenge could trigger ...

Increased accumulation of extravascular lung water after repetitive deep trimix dives was recently reported. This effect was evident 40 min post-dive, but in subsequent studies most signs of this lung congestion were not evident 2-3 h post-dive, indicating no major negative effects on respiratory gas exchange following deep dives. Whether ...

A lung cancer diagnosis and associated therapeutic management is associated with unique and varying degrees of adverse physical/functional impairments that dramatically reduce a patient's ability to tolerate exercise. Poor exercise tolerance predisposes to increased susceptibility to other common age-related diseases, poor quality of life (QOL), and likely premature death. Here ...

Pentraxin 3 (PTX3), which is mainly produced by endothelial cells, macrophages, and smooth muscle cells in the atherosclerotic region, has a cardioprotective effect. Endurance exercise training has also been known to offer cardioprotection. However, the effect of regular endurance exercise on PTX3 is unknown. This study aimed to investigate whether ...

We tested the hypothesis that exercise-induced muscle damage would increase the ventilatory (V(E)) response to incremental/ramp cycle exercise (lower the gas exchange threshold) without altering the blood lactate profile, thereby dissociating the gas exchange and lactate thresholds. Ten physically active men completed maximal incremental cycle tests before (pre) and 48 ...

Physical activity status is increasingly recognized as a reliable predictor of mortality and hospitalization in patients with chronic obstructive pulmonary disease (COPD). The reduction in physical activity occurs earlier in the clinical course of COPD than previously appreciated, possibly arising from breathlessness, reduced exercise tolerance, and adoption of a more ...

More accurate phenotyping of COPD is of great interest since it may have prognostic and therapeutic consequences. We attempted to explore the possible relationship between the extent of emphysema, as assessed by high-resolution computed tomography (HRCT), and COPD severity. We also included some study variables involving exercise tolerance evaluation and ...

Patients with severe chronic obstructive pulmonary disease (COPD) often have intrinsic positive end-expiratory pressure. Continuous positive airway pressure has been shown to decrease the inspiratory work of breathing and increases exercise capacity in these patients. To determine whether continuous negative pressure (CNP) around the chest is able to bring the ...
