Interventional
Description of intervention(s) / exposure
The intervention will be an eight week pulmonary rehabilitation program in which participants will attend twice a week for exercise training in a gymnasium, The intervention will be delivered by physiotherapists with experience in pulmonary rehabilitation.

Pulmonary rehabilitation is part of usual care. Participants will attend two sessions per week for approximately 1 hour per session during which time they will perform 20 minutes of stationary cycling, 20 minutes of walking (over-ground or using a treadmill), 10 minutes of upper limb strength and endurance training (e.g. lat pull down and pect dec using a fixed weight machine for strength training and free weights for endurance training) and 10 minutes of lower limb strength training (e.g. quads and leg press using a fixed weight machine, sit to stand, steps, wall squats).

The intensity and duration of the exercises is based on the participant’s performance at their initial assessment. For walking training the initial intensity will be set at 80% of the six-minute walk test speed. For stationary cycling, the initial intensity will be set at 60 % of the peak work rate estimated using the distance walked in the best six-minute walk test based on the equation of Hill et al 2008.

Participants will exercise at their individually prescribed exercise intensity and duration but their exercise sessions will be in the gymnasium with other participants.

A number of tests of exercise capacity will be performed before and after the pulmonary rehabilitation program. These tests will be: the 6 minute walk test, the endurance shuttle walk test (ESWT) (Revill et al, 1999) and the Glittre Activities of Daily Living (Glittre ADL) test (Skumlien et al 2006) which are standard tests regularly used in pulmonary rehabilitation programs. Participants will perform one modified Glittre ADL test in which no weighted backpack will be worn. The study will also develop and evaluate a new test, the Glittre Endurance test, which will be a modification of the Glittre ADL test

The Glittre Endurance test will be performed on the same track as the Glittre ADL test. However, the Glittre Endurance test will be performed without a backpack. For this test participants will be asked to perform the test at a speed equivalent to 90% of the speed that achieved in the Glittre ADL test (without a backpack) and to keep going for as long as possible (to a maximum of 20 minutes) or until unable to keep up the pace. The pace will be set by an audio signal. No verbal encouragement will be given during the test. Participants will be asked to score their dyspnoea and rate of perceived exertion using the 0-10 category-ratio scale (Borg 1982) at the beginning and end of the test. Pulse rate and oxygen saturation (SpO2) will be measured during the test by a pulse oximeter. The test will be terminated at patients request or at the discretion of the clinician based on clinical signs and symptoms.

Energy expenditure will be measured during the Glittre Endurance test and the ESWT using an activity monitors, the Axivity AX3 (New Castle up on Tyne, UK) and the Actigraph GT1M (Pensacola, FL, USA).

Physical activity levels of participants before commencing the pulmonary rehabilitation program will be measured over seven days by wearing of the activity monitor.

Participants will be invited to participate and will be provided with the Participant Information Sheet and any questions arising will be answered by the physiotherapists involved in the study. After agreement, participants will be asked to sign the Participant Consent Form and to attend the pulmonary rehabilitation service for testing. The participation in the study is voluntary. Subjects can withdraw at any time without having to give a reason.

The intervention will be supervised so adherence will be monitored by attendance at exercise training sessions.

Statistical methods / analysis
A sample size of 50 participants will be sufficient to provide 80% power to detect as significant, at the 5% level, a minimum 150 seconds difference in the mean Glittre Endurance test after pulmonary rehabilitation, assuming a standard deviation (SD) of 250 seconds. These data are based on findings from the Endurance Shuttle Walk Test which is a test with similar constructs (Leung et al, 2010). This sample size will also be sufficient for the evaluation of the other aims of the project.

Summary
Brief summary
Chronic Obstructive Pulmonary Disease (COPD) is a highly prevalent condition affecting approximately two million Australians (14% of the population over 40 years). It is estimated that the overall costs of COPD is $8.8 billion per annum in direct health costs and indirect costs such as lost productivity. One of the most effective interventions for managing COPD is pulmonary rehabilitation which reduces symptoms of breathlessness and fatigue, increases functional exercise capacity, improves quality of life and reduces hospital admissions. To ensure that pulmonary rehabilitation programs are achieving appropriate outcomes, valid but easily available and inexpensive tests are needed. The Glittre ADL test is a relatively new test of functional activities. However, to show improvement on the Glittre ADL, patients need to be able to increase the speed of activities. Often people with COPD after a pulmonary rehabilitation program, cannot significantly improve the speed with which they perform activities but may be able to perform the activities for longer (i.e greater endurance), with less breathlessness and fatigue. We are interested to trial a modification of the Glittre ADL test to better reflect endurance capacity for functional tasks. We also wish to determine how this measure relates to levels of daily activity since higher levels of physical activity have been associated with better health outcomes in people with COPD.

The aims of this project are: a) To develop and evaluate the a new test, the Glittre Endurance test, in people with COPD; b) To determine the relationship between the Glittre Endurance test and levels of daily physical activity measured by an activity monitor; c) To evaluate the responsiveness of the Glittre Endurance test as an outcome measure following pulmonary rehabilitation.
