Cardiorespiratory and metabolic demand of the 6-minute pegboard and ring test in healthy young adults.

OBJECTIVE: To determine the cardiorespiratory and metabolic demand of the Six-Minute Pegboard and Ring Test (6PBRT) in healthy young adults and its association with maximal arm cycle ergometer test (arm CET). METHODS: Volunteers were randomized to performed the 6PBRT test or arm CET. The second test was performed after 48 h. Oxygen consumption (VO2), heart rate (HR), dyspnea and upper limb fatigue were assessed during the tests. Demographic data, body composition, level of physical activity, arm strength and endurance were also evaluated. RESULTS: During 6PBRT, VO2 values increased from 5.8 to 11.1 mL kg-1.min-1 (p < 0.001). VO2peak, HR Mean and HRmax at 6PBRT were 47.2% and close to 65% respectively of those achieved during the arm CET. There was a positive correlation between the score on 6PBRT and VO2mean and VO2peak achieved at arm CET (r = 0.268; p = 0.003 and r = 0.247; p = 0.046 respectively). No correlation was found between the HRmean, HRpeak, level of physical activity or strength with 6PBRT (p > 0.05). Handgrip endurance had a positive correlation with score on 6PBRT (r = 0.237; p = 0.054). Body Mass Index, body fat and fat mass were negatively correlated with the score on 6PBRT (r = 0.301; p = 0.014, 0.329; p = 0.007 and r = 0.427; p = 0.001). CONCLUSIONS: The 6PBRT test showed a moderate cardiorespiratory and metabolic demand in healthy individuals in comparison of arm CET. BMI, body fat and fat mass correlated with the score on 6PBRT.

Efficacy of Acupuncture on Quality of Life, Functional Performance, Dyspnea, and Pulmonary Function in Patients with Chronic Obstructive Pulmonary Disease: Protocol for a Randomized Clinical Trial.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by the presence of chronic airflow obstruction. Previous studies have evaluated the effect of acupuncture treatment (AT) in patients with COPD. Nevertheless, these studies show a great deal of heterogeneity in treatment protocols, having sample sizes that are too small to estimate and clarify effect size and heterogeneity in patients' baseline. The aim of this study is to evaluate the effectiveness of acupuncture on quality of life, functional performance, dyspnea, and pulmonary function in patients with COPD. As such, patients will go through the following three phases: Phase I-pretreatment: period of subject selection and inclusion in the protocol, with an interview and performance of exams and tests as follows: Mini-Cog, dual-energy X-ray absorptiometry, spirometry, the Patient-Generated Index, Saint George's Respiratory Questionnaire, the six-minute walk test, the London Chest Activity of Daily Living, and the COPD Assessment Test. Phase II-8 weeks of treatment, with AT 3 times a week, with two parallel groups: Group I-with 50 subjects-AT according to the recommended technical standards; Group II-with 50 subjects-Control, without acupuncture. Phase III-Continuation of AT for 8 weeks, maintaining the subjects in the previously allocated groups and following the same methodology.

Portuguese translation and validation of the Patient Generated Index (PGI) instrument for patients with Chronic Obstructive Pulmonary Disease: individualized quality of life assessment. / Tradução para a língua portuguesa e análise das propriedades psicométricas do instrumento Patient Generated Index (PGI) para pacientes com doença pulmonar obstrutiva crônica: avaliação individualizada de qualidade de vida.

Objective To translate, adapt and validate the Patient Generated Index (PGI) for Brazilians with chronic obstructive pulmonary disease (COPD). Methods 50 volunteers with COPD, mostly men (74%), with 73.1 ± 8.9 years of age, FEV1 of 52.3 ± 14.5% of predicted and FEV1 / FVC of 56.2 ± 8.6% of predicted responded to PGI, to the Saint George Respiratory Questionnaire (SGRQ) and to perform Glittre Activities of Daily Living test (Glittre ADL). After 1-2 weeks, PGI was again applied for the analysis of relative and absolute reliability. Results The translation occurred without changes in the questionnaire. The score obtained in PGI had weak correlation with the SGRQ total score (r = -0.44, p <0.001) and with the impact domain (r = -0.40, p <0.05), presented a moderate correlation with the symptoms domain of the SGRQ (r = -0.55, p <0.001) and weak correlation with the activity domain (r = -0.31, p <0.05). A weak correlation was observed between PGI and Glittre ADL (r = -0.30; p <0.05). It was observed high reliability among the measures of PGI (ICCr = 0.94). Conclusion This study shows that the Brazilian version of PGI is a reliable and valid instrument to measure health-related quality of life (HRQL) in patients with COPD. It is a new and individualized form of evaluation of COPD patient-centered quality of life.

Análise da função respiratória em músicos instrumentistas de sopro / Analysis of the breathing function in wind instrumental musicians

Objetivo: realizar uma revisão integrativa a respeito da função pulmonar e da força muscular respiratória nos músicos de instrumentos de sopro. A relação da função respiratória com a utilização de instrumentos musicais de sopro é uma área do conhecimento ainda pouco explorada. Métodos: Realizada a revisão bibliográfica nas bases de dados MEDLINE, Embase, Cochrane, PeDro, BVS, Scopus, Web of Science e SciELO, através da combinação das palavras-chave "respiratory function test", "wind instrument", musician, "pulmonary ventilation" e "Lung Function Test". Resultados: Inicialmente foram encontrados 108 artigos, sendo que destes foram selecionados 11, totalizando 596 músicos instrumentistas de sopro, que fizeram parte dos grupos de estudo. Na maioria dos estudos os músicos apresentaram valores menores do volume expirado no primeiro segundo (VEF1) e da capacidade vital forçada (CVF) na espirometria que o grupo controle. No entanto, sem diferença quanto a relação VEF1/CVF. Assim como não há diferença na força muscular respiratória ou relação com doenças respiratórias. Conclusão: Os estudos atuais a respeito da consequência do instrumento de sopro em indivíduos não são capazes de evidenciar impactos positivos ou negativos na saúde respiratória desta população.

Objective: To conduct an integrative review of lung function and respiratory muscle strength in wind instrument musicians. The relationship between respiratory function and the use of wind musical instruments is an area of knowledge that has not been extensively explored. Methods: A bibliographic review was carried out in the MEDLINE, Embase, Cochrane, PeDro, BVS, Scopus, Web of Science, and SciELO databases by combining the keywords "respiratory function test", "wind instrument", musician, "pulmonary ventilation" and "Lung Function Test". Results: Initially, 108 articles were found, of which 11 were selected, totaling 596 wind instrumentalists who were part of the study groups. In most studies, musicians showed lower values of expired volume in one second (FEV1) and forced vital capacity (FVC) in spirometry than in the control group. However, there was no difference regarding the FEV1/FVC ratio, just as there was no difference in respiratory muscle strength or relationship with respiratory diseases. Conclusion: Current studies regarding the effect of wind instruments on individuals are unable to show positive or negative impacts on the respiratory health of this population.

RESUMO Objetivo Traduzir, adaptar e validar o Patient Generated Index (PGI) para brasileiros com doença pulmonar obstrutiva crônica (DPOC). Métodos 50 voluntários com DPOC, em sua maioria homens (74%), com 73,1 ± 8,9 anos de idade, VEF1 de 52,3 ± 14,5% do previsto e VEF1/CVF de 56,2 ± 8,6% do previsto, responderam ao PGI e ao Saint George Respiratory Questionnaire (SGRQ) e realizaram teste Glittre Activities of Daily Living (Glittre ADL). Após o período de 7-14 dias, o PGI foi novamente aplicado para análise da confiabilidade relativa e absoluta. Resultados A tradução ocorreu sem alterações no questionário. A pontuação obtida no PGI apontou fraca correlação com a pontuação total do SGRQ (r = −0,44; p < 0,001) e com o domínio impacto (r = −0,40; p < 0,05), moderada correlação com o domínio sintomas do SGRQ (r = −0,55; p < 0,001) e fraca correlação com o domínio atividades (r = −0,31; p < 0,05). Foram observadas fraca correlação entre o PGI e o Glittre ADL (r = −0,30; p < 0,05) e alta confiabilidade entre as medidas do PGI (CCIr = 0,94). Conclusão Este estudo mostra que a versão brasileira do PGI é um instrumento confiável e válido para medir a qualidade de vida relacionada à saúde em pacientes com DPOC. Trata-se de uma nova forma individualizada de avaliação de qualidade de vida centrada no paciente com DPOC.
