Background: The variety of innovations to traditional centre-based pulmonary rehabilitation (CBPR), including different modes of delivery and adjuncts, are likely to lead to differential responses in physical activity, sedentary behaviour and sleep.
Objectives: To examine the relative effectiveness of different pulmonary rehabilitation-based interventions on physical activity, sedentary behaviour and sleep.
Methods: Randomised trials in chronic respiratory disease involving pulmonary rehabilitation-based interventions were systematically searched for.
Background: Eccentric cycling (ECC) may be an attractive exercise method in COPD because of both low cardiorespiratory demand and perception of effort compared with conventional concentric cycling (CON) at matched mechanical loads. However, it is unknown whether ECC can be performed by individuals with COPD at an intensity able to cause sufficient metabolic stress to improve aerobic capacity.
Research Question: What are the cardiopulmonary and metabolic responses to ECC in people with COPD and healthy volunteers when compared with CON at matched mechanical loads?
Study Design And Methods: Thirteen people with COPD (mean ± SD age, 64 ± 9 years; FEV, 45 ± 19% predicted; BMI, 24 ± 4 kg/m; oxygen uptake at peak exercise [V̇O], 15 ± 3 mL/kg/min) and 9 age-matched control participants (FEV, 102 ± 13% predicted; BMI, 28 ± 5 kg/m; V̇O, 23 ± 5 mL/kg/min), performed up to six 4-min bouts of ECC and CON at matched mechanical loads of increasing intensity.
Background: Despite the wide-ranging benefits of pulmonary rehabilitation, conflicting results remain regarding whether people with COPD can improve their peak oxygen uptake (V˙O with aerobic training.
Research Question: The goal of this study was to investigate the effect of aerobic training and exercise prescription on V˙O in COPD.
Study Design And Methods: A systematic review was performed by using MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases for all studies measuring V˙O prior to and following supervised lower-limb aerobic training in COPD.
