Effect of Time of Exercise Re-training on Functional Capacity in Individuals With Chronic Obstructive Pulmonary Disease (COPD)

What this Trial Is About

Respiratory diseases pose a major health challenge and are a leading cause of death in developed countries. Pulmonary rehabilitation (PR) is a well-established treatment that helps reduce hospital readmissions, secondary events, and mortality in patients with respiratory diseases such as chronic obstructive pulmonary disease (COPD). This research investigates how the timing of exercise re-training, specifically the time of day when patients exercise, affects their functional capacity and overall recovery. The study compares two groups of patients undergoing pulmonary rehabilitation, with one group performing endurance and muscular exercises in the morning (around 9:00 am or 9:45 am) and the other group exercising in the afternoon (between 3:00 pm and 3:45 pm). The rehabilitation program includes exercise re-training combined with therapeutic patient education, delivered under medical supervision in dedicated centers. Participants complete at least 18 rehabilitation sessions over four weeks. Participants will be assessed through various tests including a 6-minute walk test to measure functional capacity, as well as tests for endurance, muscle strength, balance, anxiety and depression, and sleep quality. These assessments help researchers evaluate how exercise timing influences physical and mental health outcomes. The trial is randomized without masking and is led by Michaël Racodon, with participant involvement lasting throughout the rehabilitation period.
