Title: Impact of Resistance Training During Hospitalization in COPD Patients: a Randomized and Controlled Trial
Brief Summary: The purpose of this study is to determine whether resistance exercise are effective in combating the decline in muscle strength during an exacerbation of Chronic Obstructive Pulmonary Disease (COPD).


Options:
A: Inclusion Criteria:

1. Subjects with the Global Initiative for Obstructive Lung Disease (GOLD) stage 2-4 COPD
2. Subjects who have received HOT for at least 16 hours per day for at least 1 month at the time of informed consent
3. Subjects with PaCO2 \<= 60 torr, and \>= 45 torr at the time of screening
4. Subjects who have signed written informed consent to participate in this study

Exclusion Criteria:

1. Subjects with severe kidney, liver or cardiovascular disease
2. Subjects with active malignant tumor
3. Subjects with acute disease (i.e., acute myocardial infarction)
4. Subjects with a history of obstructive sleep apnea syndrome
5. Subjects with complications affecting efficacy endpoints and who are regarded by the investigator as inadequate for this study
6. Subjects who had experienced COPD exacerbation within the past 6 weeks prior to informed consent
7. Subjects who have been receiving nocturnal noninvasive positive pressure ventilation (NPPV) or had been received within the past 6 weeks prior to informed consent
8. Subjects with a history of tracheotomy or severe pharyngeal nasal cavity surgery within the past 6 months
9. Pregnant women
10. Subjects with cognitive impairment or mental disorder and who are regarded by the investigator as inadequate to be evaluated in this study
11. Subjects who are regarded by the investigator as being unable to operate the myAIRVO2 adequately at home
12. Subjects who are participating or wil participate in the another clinical trial at the time of informed consent
13. Any other cases who are regarded by the investigator as inadequate for enrollment
B: 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
C: Inclusion Criteria:

* patients hospitalized for exacerbation of COPD

Exclusion Criteria:

* patients presenting change in mental status (confusion, lethargy or coma)
* persistence or worsening in hypoxemia (PaO2\<40mmHg) and/or respiratory acidosis (pH\<7.25) despite oxygen supplementation or use of non-invasive ventilation
* hemodynamic instability requiring vasoactive drugs
* patients transferred to ICU
* hospitalization lower than 5 days
* diseases that prevented the exercises
D: Inclusion Criteria:

* Patients with COPD
* Eligible to participate in a exercise training intervention of 8 weeks
* Pi,max \<60cmH2O or \<50% of the predicted normal value

Exclusion Criteria:

* Major comorbidities preventing successful participation in an 8 week exercise training intervention

Answer: C
