Exercise and Neutrophil Function in COPD
A study testing Interval Exercise in people with Chronic Obstructive Airway Disease and Neutrophil Function Disorder, run by Hywel Dda Health Board at 1 site in United Kingdom.
Trial summary
Exercise is a cornerstone of pulmonary rehabilitation in the treatment of Chronic Obstructive Pulmonary Disease (COPD). Although researchers have shown numerous benefits with exercise in COPD patients, most studies have only looked at exercise tolerance and psychological outcomes following training.

About this study
Official title: A Pilot Study to Examine the Effect of Acute Exercise on Neutrophil Function in Patients With Chronic Obstructive Pulmonary Disease
Exercise is a cornerstone of pulmonary rehabilitation in the treatment of Chronic Obstructive Pulmonary Disease (COPD). Although researchers have shown numerous benefits with exercise in COPD patients, most studies have only looked at exercise tolerance and psychological outcomes following training. COPD is characterised by persistent inflammation that can cause progressive decline in lung function and multisystemic complications. This inflammation can be amplified in patients when they suffer acute exacerbations. There is a wellknown relationship between exercise, immune function and risk of infection. Exercise has also been shown to have an antiinflammatory effect when performed regularly. There is a lack of research looking into the inflammatory or immune response to exercise in patients with COPD. The exercise within this study will be individually tailored to patients with COPD based on their validated 6 minute walk test (6MWT) but the protocol will involve interval exercise that has been used previously. This type of exercise is considered most appropriate for research into mechanisms of benefit because it maintains the exercise training effects of other modalities (e.g. continuous low intensity aerobic exercise) while avoiding the occurrence of limitations to exercise in people with lung problems (e.g. dynamic hyperinflation). It also closely mirrors daily activity of someone with COPD.
The investigators want to explore the effects of exercise specifically on immune function in 15 people COPD and compare any changes to 15 Controls. By better understanding the mechanisms of how exercise affects inflammation, the investigators could eventually design better Pulmonary Rehabilitation interventions, especially for those most at risk.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Interval ExerciseOther
| Study group | Role | What they receive |
|---|---|---|
| Interval Exercise | Experimental | Subjects will undertake an interval exercise session (on a harnessed treadmill) (HP Cosmos Mercury 4.0, HP Cosmos Sports and Medical Gmbh, Nussdorf-Traustein,Germany) based on the average speed calculated from the 6 minute walk test (6MWT).
Intervals are based on the work previously done by Mador et al., 2009 who used intervals of 150% (for 1 minute) followed by intervals of 75% (for 2 minutes) based on 80% average speed from the 6 minute walk test.
This study repeated these intervals 7 times with a duration of 23 minutes in total for the exercise intervention with the 75% intervals at the start and at the end of the exercise session. No warm up was undertaken for this method as it was a walking exercise test and the risk of injury was minimised with use of the harnessed treadmill. Receives: Other: Interval Exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Neutrophil response to exercise
The primary outcome measure for this study is to examine neutrophil responses to acute exercise, including changes in the counts and function of these cells in blood and sputa in order to compare any changes between COPD and age-gender matched controls.
Measured: 4 months
Secondary outcomes (1)
Different health status and the responses on neutrophil function
The secondary outcome measures for this study is to examine the responses of inflammatory (pro and anti) mediators (e.g. cytokines) to acute exercise.
Measured: 4 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Although researchers have shown numerous benefits with exercise in COPD patients, most studies have only looked at exercise tolerance and psychological outcomes following training. COPD is characterised by persistent inflammation that can cause progressive decline in lung function and multisystemic complications.

Exercise has also been shown to have an antiinflammatory effect when performed regularly. There is a lack of research looking into the inflammatory or immune response to exercise in patients with COPD.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Neutrophil response to exercise (time frame: 4 months). It is what the study was designed to measure, not a finding.
