RESULTANTE DA DISTÂNCIA PERCORRIDA, DO LACTATO SÉRICO E DO IMPACTO NA QUALIDADE DE VIDA COM O USO DE BASTÕES NÓRDICOS NO TREINAMENTO AERÓBICO DE PORTADORES DE DOENÇA PULMONAR OBSTRUTIVA CRÔNICA

Objective: To evaluate the level of serum lactate in patients with Chronic Obstructive Pulmonary Disease and the impact on quality of life with the use of Nordic sticks. Methods: Analytical, longitudinal, prospective and quantitative clinical trial on a local scale, approved by the Research Ethics Committee of the University of the State of Pará (no 1,965,332). Seven volunteers of both sexes underwent evaluation on the first (T1), tenth (T10) and twentieth (T20) days of the six-minute walk test with the use of Nordic sticks, regarding the serum lactate dosage, degree of dyspnea and quality of life using the Saint George’s Respiratory Disease Questionnaire (SGRQ). The statistical analysis was performed using the BioEstat® 5.0 software and the significance level α = 0.05 was adopted. Results: There was an improvement in quality of life, with a reduction in two domains, according to the results in T1 and T20, (58.4 ± 10.9 vs 51.2 ± 10.6 p = 0.0054) in total and in the symptoms domain (70.0 ± 16.0 vs 59.0 ± 10.1, p = 0.0059). Improvement in the distance covered (352.4m vs 441.4m, p = 0.0029) and the degree of dyspnea in T10 (p = 0.0041) and T20 (p = 0.0150). There was no impact on the reading of serum lactate. Conclusion: The use of Nordic sticks showed a positive result in terms of reducing dyspnea, increasing the distance covered and improving the quality of life of patients with chronic obstructive pulmonary disease.
