Owing to difficulties in measuring ventilation symmetry, good evidence of different right/left
respiratory movements has not yet been provided. We investigated VT differences between …

Background Pursed-lip breathing (PLB) is a strategy often spontaneously employed by
patients with COPD during distress situations. Whether and to what extent PLB affects …

Background: Recent studies have shown weak associations among FEV 1 , bronchial
hyperresponsiveness (BHR), sputum eosinophils, and sputum eosinophil cationic protein (ECP), …

To understand how externally applied expiratory flow limitation (EFL) leads to impaired
exercise performance and dyspnea, we studied six healthy males during control incremental …

Background To our knowledge, no data have been reported on the effects of exercise
training (EXT) on central respiratory motor output or neuromuscular coupling (NMC) of the …

Lung and chest wall mechanics were studied during fits of laughter in 11 normal subjects.
Laughing was naturally induced by showing clips of the funniest scenes from a movie by …

Background In many studies of patients with muscle weakness, chronic hypercapnia has
appeared to be out of proportion to the severity of muscle disease, indicating that factors other …

To determine how decreasing velocity of shortening (U) of expiratory muscles affects breathing
during exercise, six normal men performed incremental exercise with externally imposed …

Background Unlike studies on leg exercise, reports on the regulation of dynamic hyperinflation
during arm exercise are scanty. We ascertained the following in patients with COPD: (1) …

The mechanics of the chest wall was studied in seven asthmatic patients before and during
histamine-induced bronchoconstriction (B). The volume of the chest wall (Vcw) was …
