Resumo: Introduction: chronic obstructive pulmonary disease (COPD) presents both autonomic impairment and muscle dysfunction. This is related to functional limitations and disease prognosis and that is related to cardiac arrhythmia and sudden death in several conditions. The conventional resistance training (CT) have been recently recognized to increase autonomic modulation, also elastic tubing resistance training (ET) increase functional cardiorespiratory performance and muscle strength in COPD. ET is characterized by some advantages regarding load progression, acceptance, space requirements, costs, being an option for resistance training. Objective: this study investigated ET effects on autonomic modulation, muscle strength and cardiorespiratory functional performance in COPD in comparison with CT. Methods: 39 subjects with COPD were recruited, split into two groups - ET (n=20; 66,5±8,9 years; 25,5±3,5kg/m²; FEV1/FVC: 50,3±11,0) or CT (n=19; 66,0±6,9; 27,1±4,3; FEV1/FVC: 55,05±9,56) performed in 24 sessions, 3 times per week, over 8 weeks. Autonomic modulation was evaluated through heart rate variability using time (rMSSD, SDNN) and frequency domain (HF, LF). Effect of resistance training was measured through dynamometry (to knee flexion and extension, elbow flexion, shoulder flexion and abduction) and the cardiorespiratory functional performance through 6 minutes? walk test. Results: there was no significance between groups. Also, there was increment to rMSSD: (16,7±11,0 vs. 20,8±14,7; p=0,015) vs. (14,2±10,0 vs. 17,4±12,1; p=0,040); HF: (141,9±191,3 vs. 234,9±335,7; p=0,021) vs. (94,1±123,5 vs. 177,6±275,5; 0,024); shoulder abduction: (50,1±19,6 vs. 56,9±20,4; p=0,039) vs. (50,5±19,0 vs. 56,9±19,3; p=0,009); knee flexion: (101,9±34,0 vs. 116,8±43,3; p=0,030) vs. (98,6±21,5 vs. 115,1±30,8; p=0,003) and walk test: (433,0±84,8 vs. 468,9±90,8; p=0,041) vs. (397,4±99,8 vs. 426,3±101,6; p=0,001) after training for both groups, ET and CT respectively. Conclusion: ET was effective in improving cardiac autonomic modulation, peripheral muscle strength, and functional cardiorespiratory performance in subjects with COPD without differences in comparison with CT.
