Evaluation of the Effects of Eccentric Training on a Cycle Ergometer, Versus Conventional Concentric Training

Not Applicable

Completed

• Conditions: Chronic Obstructive Pulmonary Disease; Coronaropathy; Readaptation to Effort
• Interventions: Other: cycling included into a conventional rehabilitation program; Other: conventional rehabilitation program (including concentric cycle ergometer)

• Registration Number: NCT02156245
• Lead Sponsor: Centre Hospitalier Universitaire Dijon

Brief Summary

The aim of this study is to assess the efficacy of a rehabilitation protocol based on individualized combined eccentric and concentric cycle ergometer training compared to classical concentric cycle training among patients with either coronary artery disease (CAD) or chronic obstructive pulmonary disease (COPD). This study will therefore evaluate the efficacy of combined eccentric/concentric training on physical capacity and overall autonomy, and will analyse the adaptive mechanisms with regard to both adaptation to cardiac and muscular effort and tolerance.

Detailed Description

The research will take place in 3 phases:

PHASE 1 :

30 healthy volunteers will be included to test tolerance to personalized exercise on an eccentric cycle ergometer.

PHASE 2 :

15 patients suffering from coronary artery disease (CAD) and 15 patients suffering from chronic obstructive pulmonary disease (COPD) will be included to test the same protocol.

PHASE 3 :

A total of 169 patients split into 2 parallel groups will be included: a group receiving conventional rehabilitation (group A) and the other group receiving eccentric exercise combined to conventional rehabilitation (group B).

Coronary patients: 93 patients will be included (62 patients in group A and 31 in group B).

COPD patients: 76 patients will be included (38 patients per group).

Exclusion Criteria

• Person without national health insurance cover
• Severe, obstructive cardiopathy
• Severe aortic valve stenosis,
• Severe progressive heart rhythm or conduction disorders not corrected by a pacemaker and detected during the initial effort test
• Cardiac intracavitary thrombus,
• Severe pulmonary artery hypertension (PAHT systolic >70mmHg),
• Recent history of venous thromboembolism (previous 3 months),
• Impaired executive functions making it impossible to understand and adhere to a rehabilitation program (Mini Mental Test < 24),
