Brief summary
Aim of this study is to investigate the effects of treadmill versus cycling endurance training on Balance, gait performance and exercise capacity in patients with severe chronic obstructive pulmonary disease. Patients will be recruited during a 3-week inpatient pulmonary rehabilitation program and will be randomized into one of two intervention groups. Walking intensity in the treadmill group will be set at 80 percent of the average speed of the 6-minute walking test. The cycling group will exercise at an intensity of 60 percent according to an Initial incremental cycling test. Patients will perform 5 to 6 training sessions per week. The total exercise duration will be progressively increased from 10 to 30 minutes. Walking or cycling intensity will also be progressively increased if perceived exertion during exercise is rated below 3 on the modified 10-point Borg scale.
Interventions
OTHERtreadmill endurance training
n = 15 patients with COPD. Walking intensity will be initially set at 80 percent of 6-minute Walking test Speed with progressive increase in Duration and intensity.
OTHERcycling endurance training
n=15 patients with COPD. Cycling intensity will initially be set at 60 percent of Peak work rate with progressive increase in Duration and intensity

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in step symmetry during 20m walking | measurement on day 1 and 21 | Patients walk 20m while wearing the Mc Roberts move test device (triaxial accelerometer) which performs a gait analysis |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in balance performance during semi-tandem stance | measurement on day 1 and 21 | patients stand still for 10 seconds on a force platform that measures absolute path length of the center of force. |
| Change in balance performance during Romberg stance | measurement on day 1 and 21 | patients stand still for 10 seconds on a force platform that measures absolute path length of the center of force. |
| Change in balance performance during single leg stance | measurement on day 1 and 21 | patients stand still for 10 seconds on a force platform that measures absolute path length of the center of force. |
| Change in muscle power during counter movement jump | measurement on day 1 and 21 | patients jump on a force platform as high as possible. The Outcome is Watt per Kilogram Body weight |
| Change in 1 Minute sit to stand test | measurement on day 1 and 21 | Patients try to perform as many repetitions as possible of standing up and sitting down from a chair with crossed arms on a force platform during 1 minute |
| Change in peak muscle strength | measurement on day 1 and 21 | isometric peak torque of the knee extensor muscles are measured in 90° knee angle |
| Change in 4 meter gait Speed test | measurement on day 1 and 21 | patients have to walk 4 meters at their usual Speed. Outcome is the average Speed during the 4m walk. |
| Change in 6-minute Walk test | measurement on day 1 and 21 | the best out of two 6- Minute Walk Tests will be used for analysis |
| Change in Hospital anxiety and Depression scale | measurement on day 1 and 21 | the Hospital anxiety and Depression scale is a questionnaire that evaluates signs of anxiety or depression |
| Change in 5 Repetition sit to stand test | measurement on day 1 and 21 | Patients try to perform 5 repetitions of standing up and sitting down from a chair with crossed arms on a force platform as quick as possible |
