Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomised, controlled;
People will be randomly allocated into one of two groups.
The first group is flat-ground walking group
People in this group will be trained in the rehabilitation gym, walking around a rectanglar track starting from 30 minutes and gradually increase up to 45 minutes by week 6. The training will go for 8 weeks, 3 times per week. The walking speed of each individual is based on their incremental shuttle walk test result (75% of their peak walking speed). We aim to increase their walking speed according to their exercise tolerance each week.

Rehabilitation
Comparator / control treatment
People will be randomly allocated into one of two groups.
The second group is cycling group
People in this group will be trained in the rehabilitation gym with a stationary bike, starting with 30 minutes training and gradually increase up to 45 minutes. The initial intensity is set at 60% of their peak work rate achieved in the incremental cycle test. The training will go for 8 weeks, three times per week. We aim to increase their exercise intensity according to their exercise tolerance each week.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
participants will be randomised after initial baseline testing by a computer program.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation using a computer-based program. The stratification is based on the percentage of predicted six-minute walking distance, forced expiratory volume in the first second (FEV1), symptom which limits the peak incremental cycle test performance
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
The aim of the project is to determine whether the benefit of flat-ground walking training is similar to cycling training in improving exercise capacity and health related quality of life (HRQoL) in patients with chronic obstructive pulmonary disease (COPD).

Hypothesis: On completion of an eight-week training program, subjects with COPD will demonstrate similar improvement in exercise capacity and HRQoL in the flat-ground walking training group and the cycling grop.
