BackgroundGiven the relative importance of cognitive impairment, there was considerable interest in identifying the cognitive profile of PD patients, in order to ensure specific and appropriate therapeutic interventions.PurposeTo determine the effects of physical exercise programs on cognitive function in PD patients, compared with the control group.Data sourcesMedline, Cochrane, Scopus, PEDro and Web of Science (last searched in September 2016).Study selectionRandomized clinical trials examining the effects of physical exercise programs and cognitive function in PD patients. Nine studies fulfilled the selection criteria and were included in this review.Data extractionCharacteristics of the publication, characteristics of the participants, test used for cognitive screening, cognitive domain assessed, tools used to assess cognitive function, characteristics of the experimental intervention, characteristics of the control group, mean results and standard deviation of function cognitive. The PEDro score was used to evaluate methodological quality.Data synthesisMost eligible studies showed good methodological quality based on the PEDro scale. Studies have shown that adapted tango for PD patients, cognitive training combined with motor training, and treadmill training promote the preservation or improvement of cognitive function in PD patients.LimitationsThe diversity of cognitive tests used to assess cognitive function and the high heterogeneity identified between the physical exercise programs.ConclusionsPhysical exercise programs promote positive and significant effects on global cognitive function, processing speed, sustained attention and mental flexibility in PD patients, at a mild to moderate stage for patients with a 6-year clinical diagnosis of PD. However, treadmill training performed 3 times a week for about 60 minutes and for a period of 24 weeks produced larger improvements in cognition.

To identify and characterize the scientific literature on the effects of exercise on Alzheimer's disease, research was conducted in the following databases: MEDLINE, CINAHL, Web of Science, and Scopus. These MeSH terms--"exercise", "motor activity", "physical fitness", "Alzheimer disease", and its synonyms in English--were used in the initial search to locate studies published between 2003 and 2013. After reading the 12 final articles in their entirety, two additional articles, found by a manual search, were included. Of these, 13 had beneficial results of exercise in Alzheimer's disease. Given the results discussed here, the exercise may be important for the improvement of functionality and performance of daily life activities, neuropsychiatric disturbances, cardiovascular and cardiorespiratory fitness, functional capacity components (flexibility, agility, balance, strength), and improvements in some cognitive components such as sustained attention, visual memory, and frontal cognitive function in patients with AD.

O exagero e a exacerbação de tarefas acadêmicas, aliados à conciliação de estudo e trabalho, podem levar estudantes a apresentarem alguns sintomas da Síndrome de Burnout. Neste contexto, esta revisão de literatura visa analisar publicações que abordem a Síndrome de Burnout em estudantes universitários. Foram consultados periódicos, dissertações, teses, livros e capítulos de livro, ligados às áreas da Educação e da Educação Física, que trouxessem maiores subsídios para o estudo desta temática. As informações obtidas na literatura revelam a demanda de estudos centrados em estudantes da área da Saúde e de reflexões sobre os fatores de risco, possíveis de desencadear a Síndrome de Burnout, durante a formação inicial. O período de estágios curriculares simboliza a etapa decisiva do curso para desencadear os sintomas da síndrome, por deparar-se o futuro profissional com situações reais em que problemas, dificuldades e limitações da prática laboral ficam evidentes.

PurposeThe present study aimed to determine the effect of demographic characteristics, occupation, anthropometric indices, and leisure-time physical activity levels on coronary risk and health-related quality of life among military police officers from the State of Santa Catarina, Brazil.MethodsThe sample included 165 military police officers who fulfilled the study’s inclusion criteria. The International Physical Activity Questionnaire and the Short Form Health Survey were used, in addition to a spreadsheet of socio-demographic, occupational and anthropometric data. Statistical analyses were performed using descriptive analysis followed by Spearman Correlation and multiple linear regression analysis using the backward method.ResultsThe waist-to-height ratio was identified as a risk factor low health-related quality of life. In addition, the conicity index, fat percentage, years of service in the military police, minutes of work per day and leisure-time physical activity levels were identified as risk factors for coronary disease among police officers.ConclusionsThese findings suggest that the Military Police Department should adopt an institutional policy that allows police officers to practice regular physical activity in order to maintain and improve their physical fitness, health, job performance, and quality of life.

Background: Physical activity is a positive component of human health. Its effects are associated with improvement in physical, psychological and social aspects of quality of life. Physical activity is therefore an important factor in the rehabilitation of amputees. Objective: To analyse the relationship between physical activity and quality of life for amputees in southern Brazil. Study Design: Descriptive, cross-sectional design with nonrandomized sample. Methods: A total of 40 questionnaire instruments were distributed to subjects who met the inclusion criteria, with a response rate of 55% (22 individuals, n = 15 males, n = 7 females). Outcome measurements were obtained through the International Physical Activity Questionnaire and World Health Organization Quality of Life-Bref. Results: The sample was characterized by physically active adult male prosthetic users with positive quality of life, and amputation below the right knee caused by mechanical trauma related to traffic accidents with motorcycles. Significant correlations were identified between all domains of quality of life and between level of physical activity and psychological quality of life. No correlation was identified between gender and quality of life variables or physical activity levels. Conclusions: This study showed that in very active amputees of both genders, level of physical activity is not associated with quality of life except for the psychological domain. Clinical relevanceThis paper contributes to understanding of the importance of physical activity for the quality of life of amputees, principally of active individuals with lower limb amputations. It provides evidence for the relevance of physical mobility in the process amputee rehabilitation, mainly for psychological domain of quality of life.

Silva, FCd, Iop, RdR, Andrade, A, Costa, VP, Gutierres Filho, PJB, and Silva, Rd. Effects of physical exercise on the expression of microRNAs: A systematic review 34(1): 270–280, 2020—Studies have detected changes in the expression of miRNAs after physical exercise, which brings new insight into the molecular control of adaptation to exercise. Therefore, the objective of the current systematic review of experimental and quasiexperimental studies published in the past 10 years was to assess evidence related to acute effects, chronic effects, and both acute and chronic effects of physical exercise on miRNA expression in humans, as well as its functions, evaluated in serum, plasma, whole blood, saliva, or muscle biopsy. For this purpose, the following electronic databases were selected: MEDLINE by Pubmed, SCOPUS, Web of Science, and also a manual search in references of the selected articles to April 2017. Experimental and quasiexperimental studies were included. Results indicate that, of the 345 studies retrieved, 40 studies met the inclusion criteria and two articles were included as a result of the manual search. The 42 studies were analyzed, and it can be observed acute and chronic effects of physical exercises (aerobic and resistance) on the expression of several miRNAs in healthy subjects, athletes, young, elderly and in patients with congestive heart failure, chronic kidney disease, diabetes mellitus type 2 associated with morbid obesity, prediabetic, and patients with intermittent claudication. It is safe to assume that miRNA changes, both in muscle tissues and bodily fluids, are presumably associated with the benefits induced by acute and chronic physical exercise. Thus, a better understanding of changes in miRNAs as a response to physical exercise might contribute to the development of miRNAs as therapeutic targets for the improvement of exercise capacity in individuals with any given disease. However, additional studies are necessary to draw accurate conclusions.
