Abstract
Resistance training is golden evidence for the treatment of systemic muscle disorders in COPD patients. Aims:Analyze the percentage gain in functional capacity in COPD patients undergoing resistance training and correlate this data with muscle strength.We assessed 44 stable COPD(FEV1%53,25±20,81; age 65,84±8,63; BMI 25,51±4,21;) undergoing resistance training for 8 weeks.27 subjects (FEV1%57,70±23,68 ;age65.81 ± 8.6;BMI25.99 ± 3.9) underwent conventional resistance training(CT) and 17(FEV1% 46,19±12,88; age 65.88 ±9.0;BMI 24.74±4.6) trained with elastic tubing (ET).Functional capacity was evaluated by the six-minute walk test(6MWT) and muscle strength by dynamometry.The CT was performed at moderate intensity at 60-80% of 1 maximum repetition(3 x 10) and ET group trained at sets of 2-7 repetitions, individually determined by resistance to fatigue test, both performed knees flexion and extension, shoulders flexion and abduction and elbow flexion.Statistical analyses were performed using test T Student for parametric date or Mann Whitney for non parametric date and correlations by the Spearman coefficient. Results:The comparison between groups showed significant difference(p=0.02) in the 6MWT.The ET group demonstrated 14,74% gain and the CT 7,86%.It was observed a positive correlation between functional capacity and knee extension: CT(r=0.53); ET(r:0.64), shoulder flexion: CT(r=0.39), ET(r=0.69), shoulder abduction: CT(r=0.39), ET(r=0.59), elbow flexion:ET(r=0.55). Conclusion:The elastic tubing, compared to conventional training, proved to be more efficient in improve functional capacity and also showed a higher correlation with muscle strength in COPD patients.
