Fibrosing interstitial lung diseases are characterized by loss of lung function, which leads to a decrease in quality of life and physical capacity. Several studies have shown an increase in quality of life and physical capacity after increasing physical activity in patients. There is evicence that yoga has a positive influence in patients with chronic obstructive pulmonary diseases, but so far, studies examining the effect of yoga in patients with fibrosing interstitial lung diseases are missing. Study aims are to determine the feasibilty of this study, and to determine the effects of yoga to patients' quality of life and physical capacity. Twenty patients with a fibrosing interstitial lung disease will be recruited and randomly assigned to the intervention or control group. Several questionnaires regarding quality of life will be conducted. Furthermore, the 6 minutes walking test, a lung function test and a biomarker analysis will be conducted at baseline and follow-up. The intervention group will participate in a 12 week yoga class, whereas the controll group will not participate. Yoga classes will be offered to the control group after the study. In addition, focus group interviews will be conducted at baseline and follow-up with the intervention group.
Patients with a fibrosing interstitial lung disease will be recruited. In total 20 patients will be recruited, 10 for the intervention group and 10 for the control group. The Intervention group will participate in a 12 week yoga class with classes twice a week for about 1 hour. The control group will not participate in a yoga class. At baseline all patients will conduct a 6 minutes walking test, a lung function test, several surveys to measure health related quaility of life (King's Brief Interstitial Lung Disease Questionnaire (K-BILD), Hospital Anxiety and Depression Scale (HADS), Interstitial Lung Disease Anxiety questionnaire), and some blood will be drawn for biomarker analysis. Furthermore, participants in the Intervention group will participate in two focus group interviews, one at baseline and the second one at 12 week follow-up.

Change from baseline quality of life at 12 weeks: King's Brief Interstitial Lung Disease Questionnaire (K-BILD)
Quality of life will be measured with King's Brief Interstitial Lung Disease Questionnaire (K-BILD). It is a 15-item validated questionnaire assessing health status in patients with an interstitial lung disease. Questions are related to three domains: breathlessness and activities, psychological aspects, and chest symptoms. Each question has 7 possible answers. The questionnaire has a scale from 0 - 100, in which 100 means highest quality of life.
Time frame: baseline and 12 week follow-up
Change in physical capacity
Physical capacity will be measured by the 6 miuntes walking test
Time frame: baseline and 12 week follow-up
Feasibility of a yoga class in patients with fibrosing interstitial lung diseases: focus group interview
Evaluation of the study by a focus group interview
Time frame: 12 week follow-up
Change from baseline quality of life at 12 weeks: Hospital Anxiety and Depression Scale (HADS)
Quality of life will be measured with the Hospital Anxiety and Depression Scale (HADS). It is a 14-item questionnaire, 7 items are related to depression and 7 items are related to anxiety. Each question has 4 different answer options, each scored from 0-3. Scores are summed up for each field (depression or anxiety) with 0 points as lowest possibility and 21 scores as highest (0-7 = normal, 8-10 = borderline abnormal, and 11-21 = abnormal).
Time frame: baseline and 12 week follow-up
Change from baseline quality of life at 12 weeks: Interstitial Lung Disease Anxiety-questionnaire
Quality of life will be measured with Interstitial Lung Disease Anxiety-questionnaire. This is a 37-item questionnaire with 5 answer possibilities for each question (never, rare, sometimes, often, always). Total scores are a sum of all questions. Lowest score = 0, highest score = 136. The higher the score the better is the patients' quality of life.
Time frame: baseline and 12 week follow-up
