Brief Summary

Aims: To prove the benefits of an specific strength training program in COPD patients compared to those achieved with the traditional endurance training. We will assess which is the proper training modality and which of them is the most beneficial according to the features of the patient to whom it is applied. Subjects and Methods: We will study 66 patients diagnosed of COPD with a moderate-severe obstruction (FEV1\<60%) and clinically symptomatic. The monitoring will be done for 3 moths. Patients will be differentiated between COPD with "predominant chronic bronchitis" and COPD with "predominant emphysema", with regard to clinical, functional and radiological criteria. After stratification of the sample, patients will be prospectively assigned to three groups of 22 patients each: a) Endurance training group, on cycle ergometer at a workload of 70% VO2max. b) Strength training group, with 5 different weightlifting exercises (4 sets of 6-8 repetitions). c) Mixed training group, with half the time dedicated to each type of training. Training will be developed during 12 weeks, three times per week, in 40 minutes sessions. Analysed variables, at the beginning and at the end of program will be: Chest X-ray, basic blood analyses, electrocardiogram, simple spirometry and bronchodilator test, blood gases, static pulmonary volumes, diffusion measurement and respiratory muscle pressure. Muscle strength will be assessed by means of 1RM test and the Myometer® dynamometer. Using the muscle skeletal ultrasound, we will control changes in muscle fibre size. Maximal and submaximal exercise tests on cycle ergometer will be also performed, so as a walking test (shuttle walking test). At last, we will assess treatment effect on dyspnea (Mahler's test) and quality of life (CRDQ). Hypothesis: A strength training program would significantly increase peripheral muscle power. This type of training would mainly have effect on the "predominant emphysema" COPD patient, where the important weight lost causes a decrease in muscle strength.

Outcome Measures

Primary Outcomes (1)

  • Increase in minute submaximal exercise test

    Check that exercise training increases the tolerance time of submaximal test

    Parameters will be measured at baseline and end of follow-up period of 12 months

Secondary Outcomes (4)

  • Meters increased 6-minute test after training exercise

    Parameters will be measured at baseline and end of follow-up period of 12 months

  • Kg increase in the 1RM test after training exercise

    Parameters will be measured at baseline and end of follow-up period of 12 months

  • Improvement in dyspnea with a fall of one point in the BDI

    Parameters will be measured at baseline and end of follow-up period of 12 months

  • Improved quality of life (CRQ) of at least one point (clinically significant) after exercise training

    Parameters will be measured at baseline and end of follow-up period of 12 months
