Brief summary: Background: Despite recent recommendations for the inclusion of upper-limb endurance training in exercise training programs (ET) for patients with COPD, the majority of theses programs are yet focused only in lower-limb endurance training. However, these patients may have a hindered performance during the execution of simple activities of daily living (ADL) involving the upper-limbs. Therefore, one doubt remains: is the addition of upper-limb endurance training necessary? Aims: To verify whether patients with COPD become more physically active in daily life, as well as whether they improve ADL performance after two protocols of ET: 1) traditional ET (TET; endurance exercises of the lower-limbs and strengthening exercise for upper- and lower-limbs) and 2) TET + additional upper-limb endurance exercise (AULET). Methods: Patients with COPD (n= 64) will be included in this randomized controlled clinical trial. Before randomization to TET or AULET patients will be evaluated regarding physical activity in daily life (PADL; accelerometers), lung function (plethysmography), respiratory muscle strength (maximum ins- and expiratory pressures), body composition (bioelectrical impedance), performance in ADL (Londrina ADL protocol), maximum exercise capacity (symptom limited maximum test of lower and upper limbs), submaximal exercise capacity (endurance time at 80% of the maximum upper- and lower-limb capacity), functional exercise capacity (six-minute walk test and six-minute pegboard and ring test), peripheral muscle strength (one-repetition maximum test and dynamometry), healthy-related quality of life (Chronic Respiratory Questionnaire), health status (COPD assessment test), functional status (London Chest Activity of Daily Life scale) and symptoms of anxiety and depression (Hospital Anxiety and Depression Scale). Patients in both groups will exercise three times per week for 12 weeks. TET will be composed by endurance exercise for the lower-limbs (walking on treadmill and lower-limb cycling) plus strengthening exercises for upper- and lower limbs. Group AULET will perform the same exercises plus the additional upper-limb endurance training (upper-limb "cycling"). Patients will be evaluated by the same procedures after the ET. Hypothesis: The addition of upper-limb endurance training will increase PADL and ADL performance to a greater extent than the traditional exercise-training program alone due to greater reduction of physical activity-related dyspnea.

Detailed description: Patients with chronic obstructive pulmonary disease (COPD; n=64) will be recruited by convenience and, thereafter, included in this randomized controlled clinical trial. The execution of all the procedures involved in this study will be performed at the Laboratory of Research in Respiratory Physiotherapy (LFIP), located at the University Hospital of the State University of Londrina, Brazil. Prior to starting the exercise training program patients will be evaluated regarding: 1) physical activity in daily life (PADL) by the MoveMonitor (McRoberts, The Netherlands) and by the ActGraph (ActGraph, USA) for seven consecutive days during awake time; 2) lung function by plethysmography; 3) maximum ins- and expiratory pressures (MIP and MEP, respectively) by manovacuometry; 4) body composition by bioelectrical impedance; 5) Performance in activities of daily living (ADL) by the Londrina ADL protocol (LAP), a protocol recently developed at our laboratory, composed by five common activities usually performed by the patients in real life situations; 6) Maximum exercise capacity by the symptom limited maximum test on lower- (increase of 10 watts/minute at a cadence of 50-60 rotations per minute \[rpm\]) and upper-limbs (5 watts/min at a cadence of 50-60 rpm) performed on cycle ergometer; 7) submaximal exercise capacity (endurance time) for the lower- and upper- limbs at 80% peak work of the respective maximum exercise capacity; 8) functional exercise capacity by the six-minute walk test and the six-minute pegboard and ring test; 9) peripheral muscle strength by the one-repetition maximum test (quantified in kg) of the knee extensors, hip abductors, elbow flexors and extensors, shoulder adductors, and dorsal muscles; and by isometric dynamometry (quantified by kgf) of the quadriceps; 10) Health-related quality of life by the Chronic Respiratory Questionnaire; 11) Health status by the COPD assessment test; 12) functional status by the London Chest Activity of Daily Living scale; 13) symptoms of anxiety and depression by the Hospital Anxiety and Depression scale; 14) and dyspnea sensation in daily life by the Medical Research Council scale. Internationally applied protocols will be followed for all the above-mentioned procedures, and local reference values will be used when appropriated. After the evaluations, patients will be randomly allocated for the traditional exercise-training program (TET) or to TET plus additional upper-limb endurance exercise-training program group (AULET).

After randomization, patients allocated to the TET group will perform lower-limb endurance exercise training on treadmill and on cycle ergometer. For the treadmill, patients will start exercising at 70% of the six-minute walk test average speed and, progressively, the intensity will be increased up to 110% of the six-minute walk test average speed until the last week of the program. For the cycle ergometer, the intensity will start at 60% of the maximum exercise capacity increasing up to 100% until the last week of the program.

For the exercise performed both on treadmill and on cycle, patients will start exercising for 10 minutes, aiming to achieve 20 minutes at the last week. In addition to the pre-schedule intensity-progression, the Borg scale (0 - 10) also will be used as auxiliary tool for guiding the exercise-intensity progression throughout the program. Additionally, patients will perform strengthening exercises for the knee-extensors, hip abductors and adductors, elbow flexors and extensors, shoulder adductors and dorsal muscles. For the strengthening exercises the intensity will start at 60% of the one-repetition maximum test increasing up to 100%. For all muscle groups, strengthening exercises will start with three series of ten repetitions, and progression is intended to achieve three series of 15 repetition by the last week. In addition to the exercises that the TET will be submitted, patients in the AULET will perform additional upper-limb endurance exercises on arm-cycle ergometer, starting at 60% of the maximum exercise capacity, for ten minutes, progressing until 95% of the maximum exercise capacity for 20 minutes in the last week. Borg scale will be used as in the TET to guide exercise-training intensity progression for the upper-limb cycling. In both groups, vital sings (i.e., heart rate, arterial pressure and peripheral oxygen saturation \[SPO2\]) will be continuously monitored throughout exercise-training sessions. Noteworthy, for those patients developing exercise desaturation (i.e., SPO2 bellow 90% or a drop higher than 4%) oxygen will be offered at a dosage enough to increase peripheral saturation above the desaturation nadir. Patients composing both groups will also receive educational sessions about topics related to disease burden, treatment and self-management.
