The study aims to test the benefits of a semi-automated tele-coaching program to coach adult participants with chronic lung disease towards a more active lifestyle.
The level of physical activity (PA) has been shown to be an important predictor for morbidity and mortality in individuals with chronic respiratory diseases, for instance Chronic Obstructive Pulmonary Disease (COPD) or Idiopathic Pulmonary Fibrosis (IPF). Physical inactivity and sedentary behavior is a common feature of patients with chronic respiratory diseases. Pulmonary rehabilitation is known as a beneficial intervention in exercise capacity, disease symptoms and quality of life in respiratory diseases. Despite the overall large benefits on exercise capacity and other variables described above, it does not automatically translate into increases in PA. Recent literature shows that coaching programs specifically aiming to increase PA are more likely to result in PA changes. Therefore, this study was designed to investigate the impact of 3-month (12 weeks) tele-coaching intervention on PA level of adult participants suffering from a chronic lung disease.

The participants are instructed to use a "Fitbit" fitness tracker to record the number of steps. This device is compatible with the "m-PAC" App, which was developed for this specific group of participants (individuals suffering from a chronic lung disease). The participants receive a feedback via the "m-PAC" App every day and they also receive a week report to be albe to adjust their step goal. They are asked to increase or keep their week goal every Sunday after reviewing a weekly report. The participants also receive tips for their PA improvement and they are asked for medication change specification (every Wednesday).

Objective measurement of physical activity
Change in weekly mean step count 12 weeks post randomization in the intervention group as compared to the control group.
Time frame: 12 weeks
Physical activity parameters
Objectively measured mean daily time in at least moderate intense activity, walking time, movement intensity and activity bout duration.
Time frame: 12 weeks
Spirometry 1
Respiratory muscle function 1 (VC = vital capacity, FVC = forced vital capacity, FEV1 = forced expiratory volume at one second \[L\]).
Time frame: 12 weeks
Spirometry 2
Respiratory muscle function 2 (PEF = peak expiratory flow \[L/min\]).
Time frame: 12 weeks
Spirometry 3
Respiratory muscle strength (MIP = maximum inspiratory pressure, MEP = maximum expiratory pressure, P0.1 = airway occlusion pressure \[kPa\], TTmus = tension time index).
Time frame: 12 weeks
Six minute walk test
Functional exercise capacity.
Time frame: 12 weeks
Isometric Quadriceps force
Isometric Quadriceps strength measurement.
Time frame: 12 weeks
Questionnaire 1
Health status evaluation: 36-Item Short Form Survey (SF-36). There are 8 scales. Each scale is directly transformed into a 0-100 scale (each question carries equal weight). The lower the score is, the more disability it expresses.

Time frame: 12 weeks
Questionnaire 2
Interstitial lung disease specific health-related quality of life evaluation: The King's Brief Interstitial Lung Disease (KBILD) questionnaire. A15-item validated questionnaire. The total score ranges from 0-100. There are three domain scores: Psychological, Breathlessness and activities and Chest symptoms. The higher score reflects better health-related quality of life.
Time frame: 12 weeks
Questionnaire 3
Anxiety and depression evaluation: Hospital Anxiety and Depression Scale (HADS). There are 14 items. The scoring ranges from 0 to 21. The higher the score, the more severe the anxiety and depression level is.
Time frame: 12 weeks
Questionnaire 4
Fatigue evaluation: Multidimensional Assessment of Fatigue (MAF) Scale. It contains 16 items. Scores range from 1 (no fatigue) to 50 (severe fatigue) and the higher score means worse fatigue.
Time frame: 12 weeks
