Duarte VS, Santos ML, Rodrigues KA, Ramires JB, Arêas GPT, Borges GF. 194 e quadril juntos; outras regiões foram citadas com menor recorrência. Os exercícios que tiveram maior destaque foram exercícios aquáticos, isocinéticos, treinamento de força muscular, caminhada, além da educação em saúde que também foi muito utilizada nos estudos selecionados. Conclusão: Pôde-se constatar por esta revisão que os estudos demonstram a eficácia do uso de exercícios na melhora dos sintomas decorrentes da osteoartrose, porém, não há um consenso quanto aos parâmetros de aplicação, como intensidade e duração de cada tipo de exercício.

AbstractIntroduction: Osteoarthritis (OA) is a chronic degenerative joint disease that is evidenced by the wear of joint's cartilage, in which often reaches the joints that support weight, like knee. Objective: To describe the principal evidence associated with the use of exercise in improving symptoms of osteoarthritis resulting in individuals over 50 years. Materials and methods: This is a systematic review of literature with the use of electronic databases of journals indexed: National Library of Medicine (MEDLINE -PubMed), Latin American and Caribbean Center on Health Sciences (LILACS), and based Scientific Electronic Library Online (SciELO). Results: There were 1405 articles were selected in the databases SciELO, LILACS, PubMed and MEDLINE with these 101 articles were selected. Among the areas affected by osteoarthritis, the knee was the most frequently mentioned, followed by knee and hip together, other regions were also cited with less intensity. The exercises that have become more prominent were water exercises, isokinetic, muscle strength training, walking, and health education has also been widely used in selected studies. Conclusion: It was found that through this review that studies show the efficacy of exercise in improving the symptoms caused by osteoarthritis, but there is no consensus on the application parameters such as intensity and duration of each exercise.

BackgroundElastic resistance bands (ERB) combined with proprioceptive neuromuscular facilitation (PNF) are often used in resistance muscle training programs, which have potential effects on peripheral muscle strength. However, the effects of the combination of ERB and PNF on respiratory muscle strength warrant further investigation. ObjectivesThe assessment of the effects of PNF combined with ERB on respiratory muscle strength. MethodTwenty healthy, right-handed females were included. Subjects were randomized to either the resistance training program group (TG, n=10) or the control group (CG, n=10). Maximal expiratory pressure (MEP) and inspiratory pressure (MIP) were measured before and after four weeks of an upper extremity resistance training program. The training protocol consisted of upper extremity PNF combined with ERB, with resistance selected from 1 repetition maximum protocol. ResultsPNF combined with ERB showed significant increases in MIP and MEP (p<0.05). In addition, there were significant differences between the TG and CG regarding ∆MIP (p=0.01) and ∆MEP (p=0.04).ConclusionsPNF combined with ERB can have a positive impact on respiratory muscle strength. These results may be useful with respect to cardiopulmonary chronic diseases that are associated with reduced respiratory muscle strength.
BackgroundThe study was conducted to determine the impact of chronic obstructive pulmonary disease (COPD) in association with obstructive sleep apnea syndrome (OSAS) on cardiac autonomic control and functional capacity.Subjects and methodsThe study was a cross-sectional prospective controlled clinical study. Heart rate variability indices of 24 COPD (n = 12) and COPD+OSAS (n = 12) patients were evaluated and compared by electrocardiographic recordings acquired during rest, active postural maneuver (APM), respiratory sinus arrhythmia maneuver (RSA-m), and the 6-minute walk test (6MWT).ResultsThe COPD group presented higher parasympathetic modulation during APM when compared to the COPD+OSAS group (P = 0.02). The COPD+OSAS group presented higher sympathetic modulation during RSA-m when compared to the COPD group (P = 0.00). The performance during 6MWT was similarly impaired in both groups, despite the greater severity of the COPD group.ConclusionSubjects with COPD+OSAS present marked sympathetic modulation, and the presence of OSAS in COPD subjects has a negative impact on functional capacity regardless of the severity of lung disease.
Endothelial dysfunction plays as an important role on mismatch responses that occur during exercise in patients with congestive heart failure (CHF). However, cardiac rehabilitation, a core component of management of CHF patients, can improve endothelial function, contributing to reduce the morbidity and mortality of these patients. The primary aims of this review were to describe the importance of flow-mediated dilatation (FMD) as a non-invasive validation tool to assess endothelial dysfunction and to highlight the relevance of scientific studies that evaluated the effects of exercise interventions on peripheral vascular endothelial function as measured by FMD in patients with CHF with both preserved and reduced ejection fraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
