Objective: This study aims to compare the effect of intradialytic aerobic exercise with blood flow restriction, without blood flow restriction (conventional) and no exercise (control) on muscle strength and walking endurance among chronic kidney disease patients. Design: Open label and parallel group randomized controlled trial. Subjects: Adult patients with chronic kidney disease on hemodialysis. Intervention: A 12-week intradialytic training with or without blood flow restriction compared with a control group. Main measures: Strength and walking endurance were measured using thoracolumbar dynamometry and a 6-minute walk test, respectively, before and after training. Results: A total of 66 patients were randomized into three groups: blood flow restriction group ( n = 22), conventional exercise group ( n = 22) and control group ( n = 22). There were seven dropouts, and 59 patients were included in the analysis. There was a significant increase in the 6-minute walking distance in the blood flow restriction group (from 412.7 (115.9) to 483.0 (131.0) m, P = 0.007) in comparison with the conventional exercise group (from 426.79 (115.00) to 433.2 (120.42) m, not significant) and the control group (from 428.4 (108.1) to 417.3 (100.2) m, not significant). The change in the walking distance over time was significantly different among groups (intervention group/time, P = 0.02). The simple effects test found a significant time effect only in the blood flow restriction group. There was no significant difference in strength change between the groups. Conclusion: Among chronic kidney disease patients, intradialytic exercise of low/moderate intensity with blood flow restriction was more effective in improving walking endurance than conventional exercise or no exercise.

Introduction: Hemodialysis (HD) increases the lifespan of chronic kidney disease (CKD) patients. However, HD is only partially effective in replacing renal function. The aim of this study is to compare HD adequacy between sessions with intradialytic exercise with or without blood flow restriction (BFR) with sessions without exercise.Methods: A crossover study including 22 adult CKD patients on HD. The patients were assigned to BFR (n = 11) or exercise alone group (n = 11). Each patient was submitted to four HD sessions (two with exercise and two control sessions). HD adequacy was assessed by equilibrated Kt/V-urea (eKT/V), single-pool Kt/V-urea (sp-Kt/V), urea and phosphorus rebound, urea reduction ratio (URR) and removal of urea and phosphorus in dialysate.Findings: BFR exercise improved eKt/V and sp-Kt/V (1.32 AE 0.21 vs. 1.10 AE 0.16 for control, P < 0.001; 1.53 AE 0.26 vs. 1.27 AE 0.19 for control, P < 0.001, respectively) and URR (72.5 AE 5.4% vs. 66.1 AE 7.7% for control, P < 0.001). No difference in eKt/V, sp-Kt/V or URR could be detected between exercise alone and control HD sessions. Urea rebound was lower in BFR exercise vs. control sessions (−8.9 AE 9.1% vs. 30.7 AE 12.8%, P < 0.01) and exercise alone vs. control sessions (13.3 AE 29.0% vs. 42.4 AE 15.3%, P < 0.01). Phosphorus rebound was marginally lower in exercise vs. control sessions (14.4 AE 19.1% vs. 28.4 AE 22.1%, P = 0.18). Urea and phosphorus mass removal in dialysate were marginally higher in exercise vs. control sessions (42.2 AE 19.4 g vs. 35.7 AE 12.5 g, P = 0.24; 912.1 AE 360.9 mg vs. 778.6 AE 245.1 mg, P = 0.28).Conclusions: Intradialytic exercise with BFR was more effective than standard exercise in increasing HD adequacy.

Low-intensity training with blood flow restriction (BFR) has been suggested as an alternative to physical training for older adults. The present study aimed to review the literature regarding the effect of training with BFR for older adults. The search strategyconsisted of experimental studies aimed at verifying the effects of training with BFR on any outcome in older adults. An electronic search in PubMed / Medline, Bireme Scielo, Lilacs and Cochrane Library databases, published until December 2015 was conducted. Experimental studies that considered individuals aged 50 years and over published in English or Portuguese, were included. The Downs & Black scale was used to assess the methodological quality of articles. Of the 60 studies, 12 were included in the review. Training with BFR improved body mass, torque and muscle power; functional capacity; bone health; venous compliance; peak oxygen uptake; and blood flow; balance and overall performance. The methodological quality of studies had mean score of 16.2 points (SD = 1.6). The prescription of low-intensity exercises with BFR may be an alternative of training for older adults. However, future studies should address the methodological quality, especially external validity and power, the main gaps in articles reviewed in this study.

Com o avanço da informática na sociedade, e consequentemente no sistema educacional, e a dificuldade de acessoás novas tecnologias, o uso de softwares livres mostra-se uma solução promissora. Software Livre e de Código Aberto (FOSS, do inglês Free Open Source Software) é, atualmente, uma base imprescindível em qualquer instituição. Graças aos conceitos que norteiam o movimento de software livre, é possível democratizar o acessoá essas tecnologias. Este trabalho tem como objetivos: apresentar uma forma de elaborar e conduzir oficinas sobre SLs para alunos recém-chegados em cursos de informatica; e promover o uso do Sistema Operacional GNU/Linux como uma porta de entrada para outros softwares livres, e uma alternativa ao uso de softwares proprietários. Ao final, foi realizado uma avaliação qualitativa baseada na observação direta e nos dados colhidos por meio de questionários.

Focando cada vez mais as relações pessoais e o indivíduo, as organizações têm percebido a necessidade de um clima organizacional positivo para seu bom desempenho e desenvolvimento. Ao considerar as políticas de eventos como uma ferramenta motivacional e de incentivo à relação interpessoal, na pesquisa pretende-se  aprofundar no assunto para estabelecer uma relação entre a utilização de tais práticas e seu impacto na geração de um ambiente de trabalho favorável. A realização da pesquisa deu-se em duas fases: uma de natureza exploratória-bibliográfica e outra de natureza quantitativa descritiva. Com a aplicação dos questionários foi verificado que as organizações não priorizam as necessidades e expectativas de seus funcionários, esquecendo que eles são recursos essenciais. Embora os colaboradores reconheçam que seu nível de motivação e integração são elevados com as aplicações de práticas de eventos e, além disso, afirmaram que há influências destas práticas em todo o clima da organização, são poucas as empresas que as adotam como ferramenta estratégica. Verificou-se ainda a grande disparidade existente entre a frequência e a influência desses eventos no cenário corporativo, que demonstraram a falta de conhecimento das organizações quando foi tratado na pesquisa sobre a opinião de seus colaboradores. Assim com os resultados da pesquisa percepeu-se que se as organizações investissem nos eventos corporativos com foco nos funcionários, conseguiriam elevar o estado de motivação de seus empregados.DOI: 10.7769/gesec.v5i1.262

The study aimed to review the literature on the effects related to post-exercise of graduated compression garments (GCGs) use on muscle recovery and delayed onset muscle soreness. The search was performed in Pubmed/Medline, Bireme, Scielo, and Lilacs electronic databases using the following descriptors in English: "compression clothing", "physical exercise", "recovery", "physical activity", "compression stockings" and "delayed onset muscle soreness". The search resulted in 102 articles and after removing duplicates, applying exclusion criteria and checking the reference lists, nine studies fulfilled the criteria and were included in the review. Seven studies associated the use of GCGs with reduction of delayed muscle soreness and improvement in performance after the use of compression clothes. However, the methodological quality of the studies, using PEDro scale, presented an average of 5.1±0.9 points (out of a total of 11 points), classified as intermediate. In conclusion, although the positive effects of using CGCs on improving recovery and reduction of delayed muscle soreness after physical exercises are almost consensual, the insufficient methodological quality of the included studies requires careful consideration of the results.
