About this study
Official title: Impact of Aerobic and High and Low Resistance Training on Daily Life Activities and BODE Index COPD Patients
The local and systemic manifestations that affect patients with Chronic Obstructive Pulmonary Disease (COPD) cause severe dyspnoea and limitation of functional capacity, leading to impairment in the performance of activities of daily living (ADL). The combination of aerobic and resistance training, for both upper limbs (UL) and lower limbs (LL), appears to be the physiologically most complete resource for improving quality of life and increased survival of these patients. Therefore, the aim of the study is to assess the impact of aerobic and resistance training of different intensities on the performance and dyspnoea during activities of daily living and prediction of mortality in patients with COPD. There will be include 45 COPD patients with moderate to severe obstruction, aged between 50-80 years of both gender. All patients will undergo to the following assessments and reassessments: history and anthropometric data, Scale London Chest Activity of Daily Living Scale (LCADL), modified Medical Research Council (mMRC), BODE index, test peripheral muscle strength, mobility and balance tests, 6-minute walk test (6MWT), Circuit ADL Test, 1 repetition maximum (1RM) and Incremental Cardiopulmonary Testing (ICPT). Patients will be randomly divided into two groups and undergo to the treatment program will consist of sessions lasting approximately 1 hour, three times a week for 12 consecutive weeks, totaling 36 sessions. All patients will undergo general stretching and aerobic training on a cycle ergometer with the intensity between 70-80 % of the maximum load achieved in ICPT. After aerobic training, a group of patients will achieve a protocol of low-intensity resistance training (LI-RT), with emphasis on gaining muscle strength, and the other group will be submitted to a protocol of high intensity (HI-RT), aiming greater gain in muscle strength. The calculation of the intensity of training will be conducted by the 1RM test. After the training protocol, it is expected to find improved performance and dyspnoea during activities of daily living and reduction of BODE index for both groups, however, it is expected that the group of low-intensity resistance training presents greater benefits in ADL.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low intensity resistance trainingBehavioural
Also called LIRT, Low-intensity resistance training
The LIRT group initiated the resistance training for UL with 30% of the 1RM, with 5% increases each nine sessions; therefore, the maximum load was 45% of the 1RM. The LL training initiated with 30% of the 1RM, increasing 7% each nine sessions, thus, the maximum load was 51% of the 1RM. Each exercise session consisted of three sets of 15 repetitions, with a 2 minutes interval between sets.
High intensity resistance trainingBehavioural
Also called HIRT, High-intensity resistance training
the initial load for HIRT group was 60% of 1RM for UL with 5% increases each nine sessions; therefore, the maximum load reached 75% of the 1RM. The LL training initiated with 60% of the 1RM with 7% increments each nine sessions, as a result, the maximum load after 36 sessions was 81% of the 1RM. These patients underwent three sets of eight repetitions, with two minutes intervals between sets.
Aerobic trainingBehavioural
Also called AT
Patients underwent an aerobic training in cycle ergometer, with load intensity determined as the same load the patient presented a VO2 value of 70-80% of the peak VO2 obtained in the symptom-limited CPET. Each session of aerobic training lasted 20-30min according to patient's tolerance.

| High intensity resistance training | Experimental | High intensity resistance training + aerobic training Receives: Behavioral: High intensity resistance training; Behavioral: Aerobic training |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Oxygen Saturation During Activities of Daily Living
TThe ADL performance was assessed by an adapted laboratory circuit of ADL, including: Showering, lifting and lowering containers on a shelf above the shoulder girdle, and raising and lowering pots on a shelf below the pelvic girdle.
Oxygen saturation (SpO2, %) was assessed by pulse oxymeter.
Measured: Baseline and after 36 sessions, an average of 3 months
Change in Ventilation During Activities of Daily Living
The ADL performance was assessed by an adapted laboratory circuit of ADL, including: Showering, lifting and lowering containers on a shelf above the shoulder girdle, and raising and lowering pots on a shelf below the pelvic girdle.
Ventilation (VE-l/min) was captured by a portable metabolic system.
Measured: Baseline and after 36 sessions, an average of 3 months
Change in Oxygen Consumption During Activities of Daily Living
The ADL performance was assessed by an adapted laboratory circuit of ADL, including: Showering, lifting and lowering containers on a shelf above the shoulder girdle, and raising and lowering pots on a shelf below the pelvic girdle. Gas exchange (oxygen consumption - VO2-l/min) was captured by a portable metabolic system.
Measured: Baseline and after 36 sessions, an average of 3 months
Change in Dyspnea Related During Activities of Daily Living
Dyspnea in ADL was assessed by London Chest Activity of Daily Living Scale(LCADL), that consists 15 quantitative questions of 4 domains: self-care, domestic, physical, and leisure. Subjects indicate a score of 0-5, in a total of 75 points. A higher total score indicates greater limitation in performing ADL due to dyspnea.
Measured: Baseline and after 36 sessions, an average of 3 months
Secondary outcomes (1)
Change in BODE index
In order to calculate the BODE index, the following variables were considered: BMI (body mass index), forced expiratory volume in one second, as the percentage of the predicted value (pred FEV1 %), mMRC score (modified Medical Research Council Scale) and in the 6MWD (Six-Minute Walk Distance). The score was considered according to the results obtained from the four variables (0-3 for FEV1; 0-3 for mMRC; 0-3 for 6MWD and 0-1 for BMI), and total score ranged from 0 to 10 (higher scores indicate more severity).
Measured: Baseline and after 36 sessions, an average of 3 months

Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Oxygen Saturation During Activities of Daily Living (time frame: Baseline and after 36 sessions, an average of 3 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01977469, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Feb 2019.
