Despite documented efficacy and recommendations, pulmonary rehabilitation (PR) in chronic obstructive pulmonary disease (COPD) has been underutilized. Home-based PR was proposed as an alternative, but there were limited data. The adequate exercise intensity was also a crucial issue. The aim of this study was to investigate the effects of home-based PR with a metronome-guided walking pace on fun...

McArdle's disease is the most common metabolic myopathy of muscle carbohydrate metabolism, due to deficiency of myophosphorylase and alteration of glycogen breakdown in muscle. The clinical manifestations usually begin in young adulthood, with exercise intolerance, exercise-induced muscle cramps, pain and recurrent episodes of myoglobinuria. Many patients experience the second wind phenomenon, ...

RATIONALE Idiopathic pulmonary fibrosis (IPF) is characterized by progressive dyspnea, impaired gas exchange, and ultimate mortality. OBJECTIVES To test the hypothesis that maximal oxygen uptake during cardiopulmonary exercise testing at baseline and with short-term longitudinal measures would predict mortality in patients with idiopathic pulmonary fibrosis. METHODS Data from 117 patients w...

Backgrounds: To observe the effects of aerobic exercise program on the illness symptoms and cardiopulmonary capacity of the patients with primary Fibromyalgia Syndrome (FMS) and to find out whether there is a difference or not in terms of cardiovascular capacity among the patients with primary FMS and sedentary healthy people. Materials and Methods: The study has been done on 20 female patients...

Objective: To determine the prevalence of exercise-induced bronchoconstriction among elite long-distance runners in Brazil and whether there is a difference in the training loads among athletes with and without exercise-induced bronchoconstriction. Methods: This was a cross-sectional study involving elite long-distance runners with neither current asthma symptoms nor a diagnosis of exercise-ind...

Cardiopulmonary exercise testing is useful in diagnosing the cause of exercise intolerance, in evaluating disability, and in defining the response to therapy. This testing modality is firmly founded on physiological principles. An efficient interaction of the body's systems is required to transport oxygen to the exercising muscles; failure of any system will yield characteristic changes in the ...
