The Effects of Aerobic Exercise Training on Vascular, Cardiac and Cerebral Vascular Function in COPD
17. august 2016 opdateret af: University of British Columbia
The Effects of Aerobic Exercise Training on Peripheral Vascular, Cardiac and Cerebral Vascular Function in Patients With Chronic Obstructive Pulmonary Disease
The primary cause of chronic obstructive pulmonary disease is smoking, which can lead to inflammation in the lungs and blood vessels that can lead to secondary problems such as blood vessel disease, high blood pressure and heart disease.
Aerobic exercise training has been shown to reduce the risk of heart and brain disease; however, it is currently unknown whether exercise training can have the same affect in patients with COPD.
The aim of this study is to investigate how eight weeks of aerobic exercise training improves blood vessel and heart function and brain blood flow in patients with COPD.

Detaljeret beskrivelse
Chronic obstructive pulmonary disease (COPD) is a treatable respiratory condition that is only partially reversible.
The primary cause of COPD is smoking which leads to airway inflammation and oxidative damage to the lungs, which has been linked to the development and progression of the disease.
The inflammation is not isolated to the lungs as patients with COPD also have systemic inflammation that has been linked to a number of cardiovascular comorbidities such as endothelial dysfunction, cardiovascular disease and stroke.
Evidence demonstrates that COPD patients have a greater incidence of vascular dysfunction and adverse vascular remodeling, which worsens with disease severity.
In fact, patients with COPD are at 35 times greater risk of developing cardiovascular disease and stroke than healthy aged matched individuals.
In healthy individuals and a number of chronic conditions, aerobic exercise training is well established to reduce the risk of cardiovascular and cerebrovascular disease.
The benefits of exercise are likely through improvements in endothelial function, systemic inflammation, and cardiac and cerebral vascular function.
However, whether exercise training can have the same effects in a chronic inflammatory condition like COPD has not been studied.
The purpose of this study is to determine the effectiveness of an 8 week aerobic exercise training program in patient's chronic obstructive pulmonary disease as determined by improvements in endothelial function, systemic inflammation and cardiac and cerebral vascular function.

|---|---|
|
Eksperimentel: Patients with COPD
Stable patients with COPD participated in an 8-week (24 session) individualized, non-linear aerobic exercise training program consisting of upper and lower body cycle ergometry.
|
Aerobic exercise performed on lower body stationary ergometer and an upper extremity arm crank.
Intensity (50-95% workload maximum) and durations (20-45 min) are fluctuated daily to optimize training stress and adaptation
