Exercise limitation has been described in patients with adolescent idiopathic scoliosis (AIS); however, whether the walking performance is impaired in these patients should be elucidated.
Exercise limitation in asthmatics is not correlated to disease severity but is largely due to psychological factors [ 2, 32].
Exercise limitation is a cardinal feature of interstitial lung disease (ILD), resulting in reduced ability to undertake daily activities and poor quality of life [ 1].
Exercise limitation, driven predominantly by activity-related dyspnea, is an important feature of chronic obstructive pulmonary disease (COPD) that compromises daily living activities, leads to physical deconditioning, and contributes to a reduced perceived quality of life [ 1– 6].
Mild exercise limitation is not commented on by XINT as it may be within normal limits for the general population.
Skeletal muscle dysfunction contributes to exercise limitation in patients with chronic obstructive pulmonary disease (COPD).
Pulmonary arterial hypertension (PAH) is a progressive disease which causes exercise limitation, heart failure, and death.
The purpose of this study was to examine if hormonal and metabolic responses could explain exercise limitation in Down syndrome (DS).
Persistent exercise limitation and pulmonary fibrosis are common [26 28].
Exercise outcomes after pulmonary rehabilitation depend on the initial mechanism of exercise limitation among non-oxygen-dependent COPD patients.
Subjects with emphysema-predominant COPD were older (65.6 vs 60.6 years, p < 0.0001) with more severe COPD based on airflow obstruction (FEV1 44.5 vs 68.4%, p < 0.0001), greater exercise limitation (6-minute walk distance 1138 vs 1331 ft, p < 0.0001) and reduced quality of life (St. George's Respiratory Questionnaire score 43 vs 31, p < 0.0001).
