This study intended to assess the effectiveness ten years later, after attending to a combined or aerobic exercise training program, in Chronic Obstructive Pulmonary Disease (COPD) patients. Methods: Twenty moderate COPD men, were randomized into two groups: ten patients (age-66.5±6.2 years) to a combined exercise training program (CETG), and ten (age-65.4±3.6 years) to an aerobic program (AETG), for 10W, 3xW. Outcome variables included cardiopulmonary function (cardiopulmonary exercise test

Ten years later, both groups were compared with ten patients who weren't submitted to exercise programs (CG), evaluating health service recurrence (HSR) and respiratory mortality. Results: Both exercise groups increased (p<.05) functional capacity (VO 2 peak: CETG-25±18%, AETG-26±25%); CPET time/power (CETG-42±30%, AETG-65±47%), 6MWD (CETG, 12±3%; AETG, 7±4%) and HRQL immediately after exercise, with greater benefits for the CETG (p<.05) in all variables. Ten years later, there were no differences between exercise groups on mortality and HSR. Between exercise groups and CG there were only significant differences on HSR. Conclusions: Combined exercise was more effective than aerobic with greater improvement in muscular strength, functional capacity and HRQL. Participation in exercise programs seems to reduce HSR at long-term follow-up.
