BACKGROUND: Fat mass to fat-free mass ratio (FM/FFM) assesses the combined effect of the balance between fat mass and fat-free mass.AIMS: to evaluate the associations beetween FM/FFM and clinical outcomes in asthma and to compare clinical characteristics between individuals with higher and lower FM/FFM.METHODS: 128 participants with asthma underwent anthropometric, spirometry and bioelectrical impedance assessments. Physical activity in daily life (PADL) was assessed by the Actigraph for 7 days. Daily dose of inhaled medication, steps of pharmacological treatment, Asthma Control Questionnaire, Asthma Quality of Life Questionnaire and Hospital Anxiety and Depression Scale were also assessed. Participants were classified into two groups according to the 50th percentile of reference values for FM/FFM.RESULTS: Individuals with higher FM/FFM (n=75) used higher daily doses of inhaled corticosteroids, had worse lung function and fewer steps/day when compared to those with lower FM/FFM (n=53) (P≤0.021). Associations were found between absolute values of FM/FFM with lung function (FEV1 and FVC [liters]): R2=0.207 and 0.364;PCONCLUSION: Higher FM/FFM is significantly associated with worse clinical characteristics in individuals with asthma, such as higher doses of inhaled corticosteroids, worse lung function and fewer steps/day. Moreover, higher FM/FFM is a determining factor of physical inactivity and the highest steps of pharmacological treatment for asthma.

The use of illicit substances can lead to several changes in physical and mental health, which can directly reflect on functional capacity and quality of life. However, there is a lack in the literature on the comparison of these variables between drug addicts and healthy individuals. To compare lung function, functional exercise capacity and quality of life of chemical dependents in rehabilitation process (CDRP) and apparently healthy individuals (AHI). Cross-sectional study that evaluated two groups (CDRP and AHI) matched by gender, age and BMI. Both groups were assessed for lung function (spirometry), quality of life (Short Form 36 questionnaire - SF-36), functional exercise capacity (6-minute walk test - 6MWT, 4-meter gait speed, Timed-up-and-go, Sit-to-Stand and Short Physical Performance Battery). Fifteen men in the CDRP group (31[26-39] years; BMI 23±3 kg/m2) and fifteen men in the AHI group (30[22-34] years; BMI 24±3 kg/m2) were analyzed. The CDRP group had a shorter distance covered in the 6MWT in meters (P=0.0002) and percentage of predicted (P=0.005). There was no difference in the performance of the other functional tests (P≥0.20) and in the pulmonary function (P≥0.46). The CDRP group had worse results in the functional capacity, pain, social aspects and mental health domains of SF-36 (P≤0.04), while in the domains general status, vitality, emotional and physical aspects there was no difference (P≥0.08). CDRP present similar lung function to AHI. However, the first have impaired functional exercise capacity, as well as some aspects of quality of life. Keywords: Drug Users. Motor Activity. Spirometry.

ResumoO uso de substâncias ilícitas pode levar a diversas alterações da saúde física e mental, o que pode refletir diretamente na capacidade funcional e na qualidade de vida. Porém, há uma escassez na literatura sobre a comparação dessas variáveis entre dependentes químicos e indivíduos saudáveis. Comparar função pulmonar, capacidade funcional de exercício e qualidade de vida de dependentes químicos em processo de reabilitação (DQPR) e indivíduos aparentemente saudáveis (AS). Estudo transversal que avaliou dois grupos (DQPR e AS) pareados por gênero, idade e IMC. Ambos os grupos foram avaliados quanto à função pulmonar (espirometria), qualidade de vida (questionário Short Form 36 – SF-36), capacidade funcional de exercício (Teste de Caminhada de 6 minutos - TC6, 4-metre gait speed, Timed-up-and-go, Sit-to-Stand e Short Physical Performace Battery). Foram analisados 15 homens no grupo DQPR (31[26-39] anos; IMC 23±3 kg/m2) e 15 homens no grupo AS (30[22-34] anos; IMC 24±3 kg/m2). O grupo DQPR apresentou uma menor distância percorrida no TC6 em metros (P=0,0002) e porcentagem do predito (P=0,005). Não houve diferença no desempenho dos demais testes funcionais (P≥0,20) e na função pulmonar (P≥0,46). O grupo DQPR apresentou piores resultados nos domínios capacidade funcional, dor, aspectos sociais e saúde mental do SF-36 (P≤0,04), enquanto que nos domínios estado geral, vitalidade, aspectos emocionais e físicos não houve diferença (P≥0,08). Homens dependentes químicos em processo de reabilitação apresentam função pulmonar semelhante a indivíduos aparentemente saudáveis. Entretanto, apresentam capacidade funcional de exercício prejudicada, assim como alguns aspectos da qualidade de vida. Palavras-chave: Usuários de Drogas. Atividade Motora. Espirometria.

Background: The phenotype profiling of individuals with chronic obstructive pulmonary disease (COPD) according to impairments in body composition and level of physical activity in daily life (PADL) needs to be determined.Objective: To verify if individuals with COPD classified as physically active/inactive present different characteristics within different body composition phenotypes.Methods: Individuals with COPD were cross-sectionally stratified into four groups according to fat-free and fat mass indexes: Normal Body Composition (NBC), Obese (Ob), Sarcopenic (Sarc), and Sarcopenic/Obese (Sarc/Ob). Additionally, individuals had their PADL level objectively assessed through activity monitoring during two weekdays for at least 10 h/day, and then were classified as physically active (Act) or inactive (Inact) according to international recommendations. Lung function (spirometry), exercise capacity (6-minute walking test [6MWT]) and peripheral muscle strength (1-repetition maximum [1RM]) were also assessed. 176 individuals with COPD (mean +/- standard deviation age: 67 +/- 8 years, body mass index 26 +/- 6 kg/m(2), FEV1 47 +/- 16%predicted) were classified as: NBC + Act (17%), NBC + Inact( 22%), Ob + Act (6%), Ob + Inact (10%), Sarc + Act (12%), Sarc + Inact (9%), Sarc/Ob + Act (8%) and Sarc/ Ob + Inact (16%). The Sarc/Ob + Inact group presented lower 6MWT and 1RM for knee extension compared to NBC + Act, NBC + Inact, and Ob + Act groups (p < 0.05). The Sarc/Ob + Inactgroup also presented lower FEV1% predicted, 1RM for elbow flexion and elbow extension compared to the NBC + Act and NBC + Inact groups and lower 1RM for elbow extension compared to Ob + Inact group (p < 0.05).Conclusion: The combination of sarcopenia, obesity, and physical inactivity was shown to be detrimental in individuals with COPD. Therefore, this profile is a main therapeutic target for improving PADL level and/or body composition. (C) 2020 Associacao Brasileira de Pesquisa e Pos-Graduacao em Fisioterapia.

Muscle dysfunction is one of the main features in individuals with chronic obstructive pulmonary disease (COPD). Handgrip strength (HS) has been used as a representation of general muscle strength in various populations, and a few studies found correlation between HS and other measures of upper and lower limbs' muscle strength in the general population, although this was not yet studied in depth in COPD. The aims of this study were to verify if HS is cross-sectionally well correlated with upper and lower limbs' muscle strength in individuals with COPD, and to identify a new cutoff for handgrip weakness in this population. HS was assessed by a dynamometer, whereas other muscle strength assessments comprised maximal voluntary contraction (MVC) of the quadriceps femoris and 1-repetition maximum (1RM) of biceps and triceps brachii, pectoralis major, latissimus dorsi and quadriceps femoris. Additional assessments included pulmonary function and volumes, body composition and exercise capacity. Fifty individuals with COPD were studied (65 ± 7 years; FEV1 51 ± 14%pred). HS showed moderate-to-strong correlations with all 1-RM assessments (0.62

Introduction: Measurement properties of functional tests have not been assessed yet in adults with asthma. Aims: To verify the validity, reliability, learning effect, Minimal Detectable Change (MDC) and feasibility of different protocols of three functional tests (4-Meter Gait Speed [4MGS], Timed Up-and-Go [TUG] and Sit-To-Stand [STS]) in adults with asthma. Methods: Fifty-two patients with stable asthma (49±15 years) underwent 3 sets of seven functional test protocols (4MGS and TUG at usual and maximum speeds; STS in 5-repetition, 30 seconds and 1 minute protocols) in random order by two raters. For validation analysis, results were compared with those from a sex-age matched control group and correlated with the Six Minute Walking Test (6MWT), and peripheral muscle strength, as well as with quality of life (QoL) and asthma control questionnaires. Intra and inter-rater reliability, MDC, learning effect and feasibility were verified. Results: Asthmatic subjects performed worse than controls in all functional tests (p Conclusions: Different protocols of 4MGS, TUG and STS are valid, reliable and feasible to assess functional capacity of adults with asthma.
