Impacto da combinação do treinamento aeróbio e resistido de curta duração em membros inferiores sobre a tolerância ao exercício, composição corporal e índice BODE em indivíduos idosos e com DPOC

Abstract

Introduction: The combined physical training (CPT) has been showed benefic on exercise tolerance in elderly individuals with COPD, but are little the articles that have been showed the impact on índex of prognostic and on the redution on the índex BODE in elderly individuals with COPD. Objectives: To compare the impact of the combination of aerobic training and strengh training on exercise tolerance, body composition and strengh muscle in elderly individuals with and without COPD, as well as to evaluate the impact of this treatment on the BODE index in elderly individuals with COPD. Methods: Eighteen male individuals completed the present study, nine were elders with COPD (COPDG) and nine were elders considered healthy (SG). All individuals were evaluated in terms of pulmonary function, walk distance by the sixminute walk test, cicloergometric in incremental test (CIT), cicloergometric in endurance test (CET), body composition variables and 1 repetition maximum test. Along of these variables, the COPDG individuals, were evaluated in terms of dyspnea (MRC scale) and BODE index total score. The training consisted of thirty minutes of aerobic training at 60-70% of the cicloergometric on incremental test (CIT) and subsequently three sets of fifteen repetitions of resistance training in lower limbs on leg press with an intensity of 40-60% of 1 RM. Between the end of aerobic training and the beginning of resistance, subjects performed five minutes of recovery. It were performed three sessions weekly for six weeks of CPT. Results: After the period of combined physical training, was observed significant difference in distance walked on the sixminute walk test in both COPDG and SG individuals. In the COPDG, after the CPT, there was an increase in the Wpeak by the CIT, limit time during CET, 1RM test workload (Kg) and BODE index total score reduction. Conclusion: The combined physical training promoted increase in tolerance exercise evaluated for walk distance by the six-minute walk test improvement in elderly individuals with and without COPD. We observed also that the CPT, increased workload (W) on CIT, time limit during the CET, in the 1RM test workload (Kg) and clinical redution in BODE index in elderly individuals with COPD.
