Title: A 3-month Multicenter Randomized Trial to Evaluate the Efficacy of a Physical Activity Promotion Program on the Experience of Physical Activity in Patients With COPD (Mr PAPP)
Brief Summary: The purpose of this 3 month randomized intervention study is to investigate the additional effect of a physical activity telecoaching program on physical activity in patients with COPD, compared with usual care.


Options:
A: Inclusion Criteria:

* Being over 50 and under 90 years of age.
* Being diagnosed with COPD according to the criteria of GesEPOC, with severe airflow obstruction defined as a forced expiratory volume in one second (FEV1) less than 50% of theoretical.
* "Exacerbator phenotype" defined as COPD patients having two or more moderate or severe exacerbations per year (GesEPOC guide). These exacerbations should be separated by at least 4 weeks after the end of previous treatment or 6 weeks from the start in cases that have not been treated
* Clinically stable condition, defined as 6 weeks without clinical symptoms since the last exacerbation of COPD.
* Having home oxygen therapy.
* Sign the informed consent.

Exclusion Criteria:

* Inability of the patient or caregiver to understand the procedure of Telehealth program.
* Have a life expectancy of less than one year.
* Have terminal heart failure (NYHA functional class III-IV).
* Having advanced renal insufficiency (creatinine clearance \<30%) or be on dialysis program.
* Have liver cirrhosis or be included in a program of liver transplantation.
* Be institutionalized or in Residential hospice care.
* Having a mini-mental test-score less than 24, because this score suggests dementia
* To be considered by your doctor as not comply the treatment or monitoring required by their lung disease.
* Failure to meet any of the inclusion criteria.
B: Inclusion Criteria:

* age \> 45 years
* COPD diagnosed by pulmonary function tests during clinical stability, with a ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ≤ 0.70
* clinical stability, defined as at least 4 weeks without antibiotics or oral corticosteroids.

Exclusion Criteria:

* living \>6 months/year outside of the included municipalities,
* living to a distance higher than 500 meters to any of the urban trails used for the study,
* mental disability according to the Mini Mental State Examination in its validated Spanish version
* comorbidity that could interfere with study tests (e.g., lower limb amputation)
* severe psychiatric disease or severe comorbidity limiting survival at one year, according to medical history.
C: Inclusion Criteria:

* Written informed consent must be obtained before any assessment is performed
* Male and female patients ≥ 40 years of age
* Diagnosis of COPD (GOLD criteria: post bronchodilator FEV1/FVC\< 70%)
* Current or ex-smokers with a smoking history equivalent to at least 10 pack years
* Patient should have at least 4 days of physical activity data recorded via PROactive monitors during 7 days prior to the baseline measurement

Exclusion Criteria:

* Orthopedic, neurological or other complaints that significantly impair normal biomechanical movement patterns, as judged by the investigator. Specifically if the patients' condition/ co-morbidities are such that physical activity cannot be increased, then they should not be enrolled
* Respiratory diseases other than COPD (e.g. asthma)
* Cognitive reading impairment and/or difficulties to manage electronic devices precluding interaction with the smartphone and PDA, as judged by the investigator
* Participating in or scheduled to start an outpatient rehabilitation program during the study. If the patient wishes to participate in pulmonary rehabilitation for any reason the patient can be enrolled in the study only at the end of rehabilitation
D: Inclusion Criteria:

* A physician diagnosis of COPD
* Age 45 years and older
* Affirmative response to "Are you short of breath when hurrying on the level or walking up a slight hill?"
* Post-bronchodilator FEV1/FVC \<0.7 and FEV1 \<70%

Exclusion Criteria:

* Inability to speak/read English
* Lives in a chronic care facility (i.e., nursing home, assisted living)
* Plans to move from the area within the next 18 months
* Life expectancy less than 12 months
* Participation in pulmonary rehabilitation or other clinical research in the past 12 months
* Inability to walk without assistance of a wheelchair or walker
* Inability to walk at least 110m on a 6-minute walk
* Uncontrolled angina, hypertension, psychiatric illness, or dementia
* Inability to obtain supplemental oxygen if indicated
