A força muscular corrigida pela massa corporal é um preditor melhor da baixa função física do que a força muscular absoluta em mulheres na pós-menopausa

Objetivo: Correlacionar a força muscular respiratória e a capacidade funcional em pacientes com FC. Métodos: Estudo transversal em adultos com fibrose cística. Os dados amostrais foram catalogados no Microsoft Office Excel 2007 e as variáveis analisadas pelo SPSS versão 20.0 através do teste t de Student e do coeficiente de Spearman. O nível de significância adotado foi p < 0,05. Resultados: Foram avaliados 35 pacientes com fibrose cística (44,6 ± 19,0 anos), grande parte dos pacientes de FC (n=26) não apresentaram fraqueza da musculatura inspiratória (PImáx -90,7 ± 27,4 cmH2O). Não foi encontrada estatística significativa apenas entre os pacientes adultos e idosos. Houve correlação positiva entre PImáx, PEmáx e teste de caminhada de 6 minutos (TC6) nos participantes com fraqueza muscular respiratória e nos idosos. Houve diferença estatisticamente significativa entre as médias da distância percorrida no TC6 e das pressões respiratórias máximas com a média do que foi previsto para estas variáveis. Conclusão: Todos os grupos apresentaram limitação da força respiratória e da capacidade funcional. As correlações entre as pressões respiratórias com o TC6 foram baixas e pequenas nos adultos e indivíduos sem fraqueza muscular respiratória; moderadas à alta nos idosos; pequenas à moderada nas mulheres; pequenas e negativas nos homens; e, altas naqueles com fraqueza muscular respiratória.Objective: To correlate the respiratory muscle strength and functional capacity in patients with CF. Method: Cross-sectional study in adults with cystic fibrosis. Sampling data were cataloged in Microsoft Office Excel 2007 and the variables analyzed by SPSS version 20.0 using the Student t test and the Spearman coefficient. The level of significance adopted was p < 0.05. Results: We assessed 35 patients with cystic fibrosis (44.6 ± 19.0 years), the great majority of patients in FC (n=22) did not present weakness of the inspiratory muscles (MIP -90,7 ± 27.4 cmH2O). It was not found statistically significant differences only between the adult and elderly patients. There was a positive correlation between MIP and MEP and a six-minute walk test (6MWT) in participants with respiratory muscle weakness and in the elderly. There was statistically significant difference between the averages of the distance covered on the 6MWT and the maximal respiratory pressures with the average of what was envisaged for these variables. Conclusion: All groups presented limitation of respiratory strength and functional capacity. The correlations between the respiratory pressures with the 6MWT were low and small in adults and individuals without respiratory muscle weakness; moderate to high in the elderly; small to moderate in women; small and negative in men; and high in patients with respiratory muscle weakness

O Short Physical Performance Battery é uma ferramenta discriminativa para identificar baixa qualidade de vida em mulheres na pós-menopausa sobreviventes do câncer ginecológico

Adverse events due to cancer treatment (changes in weight, reduced muscle capacity and mobility) hinder the quality of life (QoL) of cancer survivors. Nevertheless, the identification of discriminative predictors of QoL in post-menopausal women (PW) survivors of gynecological cancer (PW-SGC) has been ignored. Objective: The purpose of the present study was to examine the role of muscle capacity, mobility and body mass index (BMI) on the deterioration of QoL in PW (n = 35; 62.1 ± 8.2 years) and PW-SGC (n = 51; 60.8 ± 11.4 years). Methods: The QoL questionnaire (SF-36), anthropometrical evaluation (BMI), hand-held dynamometry (HHD) and short physical performance battery (SPPB) were applied in all volunteers. Results: The participants had overweight, low SF-36 scores and normal HHD, and no significant differences were found between both groups, however the SPPB score was higher in the PW group (p < 0.001). Linear regression analyses for QoL indicated the BMI (beta = -0.27) and the SPPB (beta = 0.57) were the strongest and most significant predictors in PW and PW-SGC, respectively. The area under the curve (AUC) for the SPPB score was 0.74 (95% CI: 0.57-0.87; P = 0.015) in the PW-SGC group and 0.62 (95% CI: 0.47-0.75; P = 0.181) in PW. Conclusion: The present study showed that the importance of BMI and mobility (SPPB) for QoL differ between PW and PW-SGC. For PW-SGC, the strongest independent predictor of QoL was mobility (SPPB), whereas BMI was the strongest contributor in PW. Moreover, the SPPB test is a discriminative predictor (or assessment tool) for identifying the low quality of life in postmenopausal women survivors of gynecological cancer.Efeitos adversos do tratamento (modificações da massa corporal e reduções da capacidade muscular e mobilidade) podem modificar a qualidade de vida (QV) de sobreviventes de câncer. Semelhantemente, a menopausa e o envelhecimento podem promover alterações antropométricas e da função física. Portanto, torna-se necessário o levantamento de ferramentas para predizer, distintamente, a QV em mulheres na pós menopausa (PM) e em mulheres na pós menopausa sobreviventes de câncer ginecológico (PMSCG). Objetivo: Examinar a contribuição da força, mobilidade e do índice de massa corporal (IMC) sobre as alterações da QV em PM (n = 35; 62,1±8,2 anos) e PMSCG (n = 51; 60,8±11,4 anos). Métodos: Aplicou-se questionário de QV (SF-36), avaliação antropométrica (IMC), dinamometria de preensão manual (DPM) e short physical performance battery (SPPB). Resultados: Participantes apresentaram sobrepeso, baixo score em SF-36 e DPM normal, sem diferenças entre os grupos. O score de SPPB foi maior em PM (p<0,001). Análise de regressão linear de QV, indicou IMC (beta = -0,27) e o SPPB (beta = 0,57), como os mais fortes preditores em PM e PMSCG, respectivamente. A área sob a curva para o score do SPPB foi 0,74 (95% CI: 0,57-0.87; P = 0,015) em PMSCG e 0,62 (95% CI: 0,47-0,75; P = 0,181) em PM. Conclusão: O presente estudo demonstrou que para PMSCG o principal preditor da QV foi a mobilidade (SPPB), enquanto o IMC foi o mais forte contribuidor em PM. Portanto, o SPPB é um teste específico para identificar reduções na QV pacientes sobreviventes de câncer ginecológico

Maior índice de massa corporal e menor circunferência da cintura estão associados com maior desempenho físico (SPPB) somente em idosas dinapênicas

Objective: To analyze the degree of physical disability in the elderly population affected by leprosy in Bahia State, between 2001 and 2012. Methods: The data relating to cases of leprosy was obtained from National System of Notifiable Diseases. Variables analyzed gender, age, race/color, education level, clinical and operational classification, degree of physical incapacity in diagnosis and discharge. Epidemiological indicators related to physical incapacity were calculated. Results: The leprosy features high magnitude in the elderly population, with a coefficient of detection of new cases higher than the general population, situated at a hyperendemic level. As to the epidemiological profile of leprosy in elderly, stands out: men, age 60 to 69 years, white race, low education level, dimorphic clinical manifestation and multibacillary operational classification. 36.25% of diagnosed cases had a physical incapacity at the time of diagnosis, with emphasis on the masculine gender. Conclusion: The high proportion of individuals with physical incapacity at the time of diagnosis suggests late diagnosis and hidden prevalence of the disease, mostly in Individuals of the male gender.Objetivo: Analisar o grau de incapacidade física na população idosa afetada pela hanseníase no estado da Bahia, entre 2001 e 2012. Métodos: Os dados referentes aos casos de hanseníase foram obtidos do Sistema Nacional de Agravos de Notificação. Variáveis analisadas: sexo, faixa etária, raça/cor, escolaridade, classificação clínica e operacional, grau de incapacidade física no diagnóstico e na alta. Foram calculados indicadores epidemiológicos relacionados à incapacidade física. Resultados: A hanseníase apresenta elevada magnitude na população idosa, com coeficiente de detecção de casos novos superior ao da população geral, situando-se em nível hiperendêmico. Quanto ao perfil epidemiológico da hanseníase em idosos, destaca-se: homens, faixa etária 60 a 69 anos, raça branca, baixa escolaridade, forma clínica dimorfa e classificação operacional multibacilar. 36,25% dos casos diagnosticados apresentavam incapacidade física no momento do diagnóstico, com destaque para o gênero masculino. Conclusão: A elevada proporção de indivíduos com incapacidades físicas no momento do diagnóstico sugere diagnóstico tardio e prevalência oculta da doença, sobretudo em indivíduos do gênero masculino

Higher Protein Intake Does Not Improve Lean Mass Gain When Compared with RDA Recommendation in Postmenopausal Women Following Resistance Exercise Protocol: A Randomized Clinical Trial

The aim of this study was to evaluate the effect of a higher protein intake on lean body mass (LBM) gain in postmenopausal women practicing resistance exercise and compare it to the Recommended Dietary Allowance (RDA) recommendation. Twenty-three postmenopausal women (63.2 ± 7.8 years) were randomized into two groups. The group with higher protein intake (n = 11) (HP) received a dietary plan with ~1.2 g·kg−1·day−1 of protein, while the normal protein (NP) group (n = 12) was instructed to ingest ~0.8 g·kg−1·day−1 of protein (RDA recommendation). Both groups performed the same resistance training protocol, 3 times a week, with progression of the number of sets (from 1 to 6 sets) and 8–12 repetitions. The intervention occurred over 10 weeks. Body composition evaluation was performed by dual-energy X-ray absorptiometry. The diet was evaluated by nine 24-h food recall summaries over the course of the study. During the intervention period, the HP group presented a higher protein (1.18 ± 0.3 vs. 0.87 ± 0.2 g·kg−1·day−1, p = 0.008) and leucine (6.0 ± 1.4 vs. 4.3 ± 0.9 g/day, p < 0.001) intake than the NP group, respectively. At the end of the intervention, there were increases in LBM both in HP (37.1 ± 6.2 to 38.4 ± 6.5 kg, p = 0.004) and in NP (37.6 ± 6.2 to 38.8 ± 6.4 kg, p < 0.001), with no differences between the groups (p = 0.572). In conclusion, increased protein intake did not promote higher LBM gain when compared to RDA recommendation in postmenopausal women performing resistance exercise during 10 weeks. This trial was registered at ClinicalTrials.gov as NCT03024125

Acute resistance exercise reduces increased gene expression in muscle atrophy of ovariectomised arthritic rats

Objective: We studied the effect of resistance exercise (RE) on mRNA levels of atrogin-1, MuRF-1, and myostatin in the gastrocnemius muscle of arthritic rats after loss of ovarian function (LOF). Material and methods : Thirty female Wistar rats (nine weeks old, 195.3 ±17.4 grams) were randomly allocated into five groups: control group (CT-Sham; n = 6); group with rheumatoid arthritis (RA; n = 6); group with rheumatoid arthritis subjected to RE (RAEX; n = 6); ovariectomy group with rheumatoid arthritis (RAOV; n = 6); and an ovariectomy group with rheumatoid arthritis subjected to RE (RAOVEX; n = 6). After 15 days of intra-articular injections with Met-BSA the animals were subjected to RE and six hours after workout were euthanised. Results : The rheumatoid arthritis provoked reduction in the cross-sectional area (CSA) of muscle fibres, but the CSA was lower in the RAOV when compared to the RA groups. Skeletal muscle atrogin-1 mRNA level was increased in arthritic rats (RA and RAOV), but the atrogin-1 level was higher in RAOV group when compared to other arthritic groups. The Muscle MuRF-1 mRNA level was also increased in the RAOV group. The increased atrogin-1 and MuRF-1 mRNA levels were lower in the RAOVEX group than in the RAOV group. The myostatin mRNA level was similar in all groups, except for the RAOVEX group, in which it was lower than the other groups. Conclusions : LOF results in increased loss of skeletal muscle-related ubiquitin ligases (atrogin-1 and MuRF-1). However, the RE reduces the atrogin-1, MuRF-1, and myostatin mRNA levels in muscle of arthritic rats affected by LOF

Moderate Increase in Protein Intake Promotes a Small Additional Improvement in Functional Capacity, But Not in Muscle Strength and Lean Mass Quality, in Postmenopausal Women Following Resistance Exercise: A Randomized Clinical Trial

The aim of this study was to evaluate the effect of a moderate increase in protein intake on muscle strength, functional capacity and lean mass quality improvements in postmenopausal women following resistance exercise. Forty-seven postmenopausal women were randomized in two groups: Normal protein (NP, n = 25), who received a dietary plan containing ~0.8 g protein·kg−1·d−1 (recommended dietary allowance—RDA recommendations); and higher protein (HP, n = 22), which a moderate increase in protein intake was recommended (~1.2 g protein·kg−1·d−1). Resistance training was performed for 10 weeks, three times/week. Muscle strength (handgrip strength and one repetition maximum test—1-RM), functional capacity and lean mass (LM) quality (muscle strength to lean mass ratio) were evaluated. Dietary intake was assessed by nine 24 h food recalls. After intervention, both groups increased similarly the leg extension 1-RM and handgrip strength. Regarding functional capacity tests, both groups increased the balance test score (SPPB) and 10 m walk test speed, with no differences between the groups. In addition, an increase in speed to perform the 6 min and 400 m walk tests was observed over the time, with an additional improvement in the HP group (time × group interaction; p = 0.007 and p = 0.004, respectively). About LM quality, leg extension 1-RM/leg LM improved over the time in both groups (p = 0.050), with no time × group interaction. All these significant changes had a low effect size. In conclusion, a moderate increase in protein intake promoted a small additional improvement in functional capacity, but it did not induce a greater increase in strength and LM quality after 10 weeks of resistance exercise in postmenopausal women. This trial was registered at ClinicalTrials.gov as NCT03024125
