With this pilot project the investigators expect that an eccentric endurance training protocol adapted to severe COPD patients will lead to gains in muscle strength, the primary outcome, and cellular adaptation (muscle morphology and oxidative capacity, mitochondrial respiratory capacity) when compared to a concentric training approach.\n\nThis information will be essential if the investigators want to design and power a randomized clinical trial that will allow assessing effectiveness of this novel rehabilitation approach.', 'detailedDescription': 'Chronic obstructive pulmonary disease (COPD) is a major respiratory illness that is both preventable and treatable. Dyspnea is the most important symptom that COPD patients experience and this can have a major impact on their daily live. While COPD is characterized by a spectrum of disease severity, most patients experience poor exercise intolerance attributable to ventilatory limitation as well as peripheral muscle fatigue, ultimately leading to severe disability.\n\nEndurance exercise is an important component of pulmonary rehabilitation and is aimed at preventing this decline in functional capacity. The effects of pulmonary rehabilitation are largely attributable to the exercise training component involving concentric muscle contractions, traditionally trough dynamic, large muscle exercise on a cycle ergometer or treadmill. However, many patients are unable to partake and benefit from such rehabilitation because of locomotor muscle weakness and severe ventilatory limitation that prevent them from exercising at intensities sufficient to provoke improvements in cardioventilatory and skeletal muscle function. Eccentric exercise is known for its unique physiologically fundamental characteristics: the lower metabolic demand for a same power output and greater muscle gains compared to the concentric exercise. For this reason, eccentric endurance training has been proposed as a novel adjunctive rehabilitative countermeasure for certain chronic diseases (such as coronary disease and COPD) and can play an important role for patients with advanced disease.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '40 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* male patients with severe COPD (FEV1/FVC \\< 0.70 and FEV1 ≤ 50% predicted of normal)\n* Patients aged 40 to 80 years old in whom exercise is not contraindicated\n* Current and ex-smokers\n* Patients who do not require oxygen therapy\n\nExclusion Criteria:\n\n* Patients presenting neurological or orthopedic problems, morbid obesity, acute medical condition or recent exacerbations (in the last four weeks)\n* Patients with recent or current participation in a rehabilitation program'}, 'identificationModule': {'nctId': 'NCT01077102', 'briefTitle': 'Eccentric Exercise Training as Novel Rehabilitation for Chronic Obstructive Pulmonary Disease (COPD)', 'organization': {'class': 'OTHER', 'fullName': 'McGill University Health Centre/Research Institute of the McGill University Health Centre'}, 'officialTitle': 'Eccentric Training as Novel Rehabilitation for COPD', 'orgStudyIdInfo': {'id': 'MUHC Pilot Project 2007'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Eccentric exercise training', 'interventionNames': ['Other: Eccentric exercise training']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Concentric exercise training', 'interventionNames': ['Other: Eccentric exercise training']}], 'interventions': [{'name': 'Eccentric exercise training', 'type': 'OTHER', 'description': 'The eccentric exercise training will be performed using a specially built cycle ergo meter where the pedals are driven in backward direction by an electric motor, which has to overcome the adjustable resistance of the electromagnetic brake.
