Introdução: A sarcopenia é decorrente da perda de massa muscular, encontrada em diversos estágios da doença renal crônica (DRC). Objetivo: O objetivo do estudo foi identificar a influência da sarcopenia nos aspectos de mobilidade de pacientes com DRC. Métodos: Trata-se de uma revisão sistemática baseada nos critérios do PRISMA, na qual foi realizada uma busca na literatura nos bancos de dados Pubmed, Scielo e CINAHL, dos últimos 10 anos, correspondente ao período de janeiro de 2008 a julho de 2018. Resultados: Para a composição do corpus foram selecionados nove estudos com abordagem na influência da sarcopenia no estado geral dos pacientes. Discussão: A DRC está associada a perda das funções regulatórias, excretórias e endócrinas do rim, cursando com diversos desfechos, dentre eles perda de massa muscular progressiva, associada ao processo de envelhecimento. Conclusão: Um alto índice de indivíduos com DRC apresentam um estado de sarcopenia, consequência da inatividade e da diminuição da síntese proteica gerando hipotrofia.

ObjectiveThe objective of this study is to investigate the association between muscle function, body composition, and metabolic control in adults with type 2 diabetes mellitus (DM2).MethodsForty‐eight individuals with DM2 were divided into four groups according to the severity of obesity (body mass index [BMI]: lean [LN, n = 10], overweight [OW, n = 16], obese class I [OBI, n = 15], and obese class II [OBII, n = 7]). Absolute peak torque (TQ), relative peak torque (TQ/body weight [BW]), total work (TW), and fatigue index (FI) were assessed by means of an isokinetic dynamometer during concentric knee extensor contraction. Spearman's correlation coefficients were used to estimate the association between measurements.ResultsAlthough OBII had higher insulin levels than both LN and OW groups, no significant differences were found between groups for TQ, TQ/BW, TW, and FI, as well as between metabolic variables and muscle measurements. There was a positive correlation between BMI and TQ (rs = .45) and resistance tests, between BMI and TQ (rs = .43), and TW (rs = .37).ConclusionMetabolic variables do not correlate with muscle strength and endurance in DM2. However, severity of obesity measured by the BMI is positively associated with muscle force‐generating capacity and endurance.

BACKGROUND: Stroke is the principal cause of disability around the world and the ensuing functional dependence (FD) can be correlated with different factors. OBJECTIVE: To determine how demographic factors and clinical characteristics after stroke distinguish patients who achieve functional independence from those who do not. DESIGN AND SETTING: Observational study at specialized neurovascular clinic in Alagoas, Brazil. METHODS: FD was classified according to the modified Rankin scale (mRs): 0 to 2 points were classified as independent (FD-), and 3 to 5 points were classified as dependent (FD+). Logistic regression analysis included age, sedentary lifestyle, the Center for Epidemiological Studies-Depression Scale (CES-D) and the National Institutes of Health Stroke Scale (NIHSS). The Mann-Whitney test and χ 2 test were used to compare groups. RESULTS: We included 190 stroke patients with a mean age of 60.02 ± 14.22 years. We found that 34.8% of the patients were classified as FD+. Lower NIHSS and CES-D scores were more associated with achieving functional independence. Most of the patients had access to physical therapy, and the mean duration of rehabilitation therapy was 65.2 minutes per week. Females had higher prevalence of depressive symptoms (P = 0.005) and rehabilitation time was shorter for hemorrhagic stroke (P = 0.02). CONCLUSION: We found a FD rate four times greater than in another Brazilian study. Lower stroke severity and fewer depressive symptoms were associated with achieving functional independence. Less than half of the patients were referred to a rehabilitation service at hospital discharge and few had access to multidisciplinary treatment.

Cycling was consolidated from the use of the bicycle, initially as a means of secular transport, developed for transportation and walking purposes, transformed into a complex sports practice of varied intensity. The final aim of sporting practice is the physical conditioning, which aims to increase the physical and motor capacity of the body, as a way to perform specific muscle activity, obtain better results, and consequently increase individual performance. The objective of this work was to evaluate lung capacity in cyclists living in the city of Maceió-AL. This is a cross-sectional and descriptive study, with anthropometric data collection and pulmonary capacity. As inclusion criteria of the study, we considered male subjects; aged ≥ 18 years; that they practiced cycling for a superior period three months ago; whether or not they are federally-official competitions; and residents of the city of Maceió / Alagoas. Sixteen male cyclists, with mean age of 31.18 ± 7.78 years and mean cycling time of 32.65 ± 7.81 months, participated in the study. As results, it was observed that 88% of the cyclists obtained values considered adequate of pulmonary capacity and only 19% obtained restrictive disorder.
