Efeito agudo do exercício físico associado a praxias ideomotoras sobre as concentrações séricas de cortisol e memória declarativa em indivíduos com idade entre 51 e 74 anos

Introduction: Several modifications are identified as aging, causing more or less limitation imposed by over the years. Among these, one can highlight the different degrees of cognitive decline, particularly memory that can involve the daily activities and the subject functionality. Studies have shown an association between levels of serum cortisol and stress imposed by the exercise on this. However, there are few studies that references the performance on cognitive aspects of declarative memory and cortisol on the exercise in the water with automatic and práxicos movements and moderate. Objective: Check the effect based on the acute physical exercise and práxicos automatic movements on the performance of visual declarative memory and in serum cortisol in subjects aged between 51 and 74 years. Materials and Methods: It builds a survey characterized as cross with a first sample of 32 physically active subjects aged between 51 and 74 years, divided into two exercise groups (March of Automatic Group - MAG and the March of Praxis Group - MPG). We used a probabilistic and random sampling for sample selection. Used the MMSE (Mini Mental State Examination) to check the general cognitive status, visual acuity test - optotypes chart "E" Rasquin and was even used the declarative visual memory test proposed by Nitrini and collaborators (1994), applying before motor stimulation and immediately after, and the day of blood collection with 2 ml for analysis of cortisol hormone. The normality and homogeneity were verified from the Shapiro-Wilk and Levene tests. Thus we adopted a descriptive statistics to characterize the sample. The Split-Plot ANOVA was used along with the paired t-test to verify the identified differences. We adopted a significance level of p <0.05. Results: It was observed that the groups (MAG and MPG) and the anthropometric variables, perceived exertion, education, cognitive assessment and visual acuity showed no significant differences (p > 0.05), showing that the groups are homogeneous, with variables and similar means. After the stimulation session, lasting 30 min, it was observed that the amount of hits for Δ of declarative memory questionnaire visual images increased, presenting significant for both groups (MAG, p < 0.001; MPG, p = 0.042). The same was observed for cortisol concentration with a reduction in the levels immediately after the stimulus (MAG and MPG, p < 0.001). Conclusion: The results showed that the exercises proposed in its acute effect provide significantly memories of gains and also showed a reduction in cortisol levels.

Impacto do exercício físico na qualidade de vida e do sono em pessoas vivendo com HIV/AIDS

The increased incidence along to new therapies for the treatment of HIV/AIDS bring way up exercise as a treatment option, as this promotes relevant changes in the general functioning of the body. The objective of this study was to evaluate in different periods the influence of exercise on quality of life and quality of sleep people living with HIV/AIDS, Natal/RN. The sample consisted of 17 people living with HIV/AIDS participating in physical exercise program, along accompanied by 25 months during the period January 2013 to April 2015. We evaluated through specific instruments quality of life, sleep quality and immunological parameters, which were evaluated before starting the exercise program and reassessed during periods of 2-4 months (short), 5-17 months (average period or intermediate) and finally to 19-25 months (long period). The results showed significant differences in five of the nine areas of quality life, pointing positive behaviors, specifically in the areas overall function, life satisfaction, health concerns, concerns about the medication and acceptance to HIV. We conclude that physical exercise promoted benefits both in short and long term, especially for the areas of quality of life of people living with HIV/AIDS and also demonstrated positive behavior changes and to aspects of sleep quality.

Efeitos do Kinesio Taping® sobre os marcadores clínicos indiretos de dano muscular induzido pelo exercício excêntrico: ensaio clínico randomizado

Objective: analyze the effect of Kinesio Taping (KT) on the indirect clinical markers of muscle damage induced by eccentric exercises in the elbow flexors in healthy individuals. Materials and methods: It is a randomized controlled trial involving sixty volunteers at age group between 18 and 28 years randomly selected. The sample into three groups with twenty participants: control group (CG) – eccentric protocol without KT, KT group – eccentric with tensioned KT, placebo group – eccentric protocol KT with no tension. The evaluations took place at four moments; the first one was the basis line (AV1), after the second protocol (AV2) and the following two groups 24 (AV3) and 48 hours (AV4) after the intervention protocol. The muscle damage was induced by sixteen maximum eccentric contractions of the elbow flexors from the non-dominant limb, divided in two sets of eight repetitions, at 60º/s, with two minutes interval. The variables analyzed were: the joint amplitude in rest, the level of pain, the joint position sense (JPS) followed of isokinetic checking with electromyographic sign capitation. These data were analyzed in software SPSS 20.0. The normality was identified by Kolmogorov-Smimov examination and then, being used the ANOVA mixed model with significance of 5%. Outcomes: a decrease was observed at joint amplitude moreover, an immediate increase of pain wich increased after 24 and remained until 48 hours at all groups searched. There was not difference at the JPS. The variables peak torque, average peak torque, total work and mean power mean reduced until 48 hours after muscle lesion in all groups. Among the groups, there was no difference in EMG values and for any of the variables. Conclusion: The KT did not influence at the indirect clinical markers of muscle lesion induced by eccentric exercises in the elbow flexors in healthy people.

Efeitos da terapia laser de baixa intensidade associada ao exercício aeróbio no reparo de tenotomia do tendão de aquiles de ratos diabéticos

Diabetes Mellitus (DM ) is a complex disease that requires continuous medical care for the reduction of risk factors in addition to glycemic control. The typical hyperglycemia of this disease produces glycosylation of proteins and so the consequence is the accumulation of glycosylation final products in various human tissues, among them, the tendon. The aerobic exercise (AE) and the low level laser therapy (LLLT) have been used to treat tendinopathies in individuals with or without DM. Objective: The aim of this study was to watch the effect of the LLLT and the AE, in association, in partial tenotomy of the tissue repair of the Achilles tendon (AT) of diabetic rats. Methods: 91 animals were utilized and divided in to the following groups: control group (GC), injured control group (GCL), diabetic group (GD), diabetic group LLLT (GD – TLBI), diabetic group trained (GD - EX) and diabetic group trained laser (GD-EX+TLBI). The animals were submitted to intervention with AE, using a protocol with a progressive increase of time (12 to 60 min) and speed of (4 to 9 m/min), and the LLLT (660 nm laser, 10mW, 4 J/cm², single point for 16 seconds, three times for week). It was analyzed morphological, biomechanical and molecular characteristics. For data showing normal distribution was used one-way ANOVA test and post hoc Tukey and data without normal distribution was used Mann Whitney test and post hoc Dunn's. It was accepted p <0.05 for statistical significance Results: The biomechanical tests indicated major improvement in the GC and GD-EX+TLBI groups when compared with the diabetic groups in the following variables: maximum load, strain, absorbed energy, stress, cross section area, elastic modulus and energy density (p<0.05). The analysis through molecular biology indicated that the association of aerobic exercise and LLLT generated an increase of the collagen I gene expression and modulated the expression of the MMP2 and MMP9 (p<0.05). No observed any major improvement in the morphological variable studied. Conclusion: the LLLT associated with aerobic exercise promotes and increase of the mechanical properties, in the control of collagen I gene expression and of the MMP2 and MMP9 of the diabetic rats.

O Supremo Tribunal Federal como agente tecnocrático no exercício da jurisdição constitucional na solução de casos complexos : análise das ações diretas de inconstitucionalidade nº 3937/SP e nº 3357/RS

Many changes have taken place in contemporary society causing impacts in its different sectors, making it much more complex and insecure than in past times. The alteration on the decision-making system of the Brazilian society is among the main changes today. The post-modern context contributed to the occurrence of the transfer of state power of the Legislative and Executive Powers to the Judiciary Power, specifically to the Federal Court of Justice, leading to an expansion on the actuation range of this institution mainly through the exercise of the constitutional jurisdiction. This has caused a crisis of legitimacy in society once the Court will now decide the political and social fundamental issues. In this scenario, the Direct Action of Unconstitutionality n° 3937/SP and n° 3357/RS are highlighted and both are being tried by the Supreme Court. Such emphasis is given, since it is a matter of high complexity and social repercussion that will be decided by a legal institution and not a political one. Thus, this work aims to analyze the role of the Supreme Court in the context of contemporary society on the trial of complex and controversial cases, particularly on the trial of Direct Action of Unconstitutionality n° 3937/SP and n° 3357/RS. This study has noticed that due to the post-modern context the majority of the Supreme Court Ministers tend to base their votes in constitutional principles and no longer limit themselves to a formal review of the constitutionality of laws, which indicates a substantialist approach. Moreover, it can be noticed the deliberative potential of the Court as well as the influence of the post-modern features, such as risk, uncertainty and insecurity on the elaboration of the Minister‟s votes. Therefore, sometimes, such as the case in study, the Supreme Court has acted as a technocratic agent in Brazilian society once fundamental political and social decisions for society especially when it comes to complex and controversial cases are being taken by the Supreme Court, which is composed by “Law technicians” and such decisions are mainly based in technical data and scientific studies. For the accomplishment of this work, it has been adopted the inductive approach and monographic procedure method and the bibliographical and documentary research technique.

Efeito do exercício físico na estabilidade de membrana de eritrócitos

CHAPTER II - This study evaluated the effects of two different types of acute aerobic exercise on the osmotic stability of human erythrocyte membrane and on different hematological and biochemical variables that are associated with this membrane property. The study population consisted of 20 healthy and active men. Participants performed single sessions of two types of exercise. The first session consisted of 60 min of moderate-intensity continuous exercise (MICE). The second session, executed a week later, consisted of high-intensity interval exercise (HIIE) until exhaustion. The osmotic stability of the erythrocyte membrane was represented by the inverse of the salt concentration (1/H50) at the midpoint of the sigmoidal curve of dependence between the absorbance of hemoglobin and the NaCl concentration. The values of 1/H50 changed from 2.29 ± 0.1 to 2.33 ± 0.09 after MICE and from 2.30 ± 0.08 to 2.23 ± 0.12 after HIIE. In MICE has occurred an increase in the mean corpuscular volume, probably due to in vivo lysis of older erythrocytes, with preservation of cells that were larger and more resistant to in vitro lysis. The study showed that a single bout of acute exercise affected the erythrocyte osmotic stability, which increased after MICE and decreased after HIIE.

A Arte de Governar: o exercício do poder pelo saber segundo Michael Foucault

As obras de Michel Foucault exercem influencia em várias áreas das ciências humanas. O mesmo fato se repetiu em teoria das organizações, onde as idéias foucaultianas estão sendo empregadas fundamentalmente para trazer novas luzes para as discussões sobre poder nas organizações. A despeito da influência significativa na área, não há discussões sobre como as obras de Michel Foucault estão sendo utilizadas. A presente dissertação de mestrado tem por objetivo sistematizar os estudos que utilizaram as idéias de Michel Foucault em teoria das organizações, problematizá-los e indicar alguns caminhos para o desenvolvimento desse tipo de análise. De uma forma geral, percebemos que a produção acadêmica em teoria das organizações baseadas nas obras de Michel Foucault tratam majoritariamente das disciplinas e deixam de lado outros aspectos da analítica do poder. Ademais, percebemos que há uma adoção simplificada da analítica do poder e uma junção acriteriosa de conceitos e noções oriundas de diferentes matrizes epistemológicas, além da inadequação da designação “pósmoderno” para classificar as obras de Michel Foucault e suas utilizações em teoria das organizações. Como possíveis desenvolvimentos, indicamos as possibilidades de análise que podem ser abertas na teoria das organizações pelo uso das noções de biopolítica e governamentalidade. / The works of Michel Foucault exert influence in various areas of the humanities. The same thing happened in organization theory, Foucauldian where ideas are being used primarily to bring new light to the discussions about power in organizations. Despite the significant influence in the area, there are discussions about the works of Michel Foucault are being used. This dissertation aims to systematize the studies that used the ideas of Michel Foucault in organization theory, problematize them and indicate some directions for developing this type of analysis. In general, we find that the academic production in the theory of organizations based on the writings of Michel Foucault deal mostly of disciplines and leave out other aspects of analytical power. Moreover, we realize that there is an adoption of simplified analytical power of an indiscriminate and a junction of concepts and notions from different epistemological matrices, besides the inadequacy of the term "postmodern" to classify the works of Michel Foucault and its uses in organizational theory. As possible developments, indicate the possibilities of analysis that can be opened in organization theory by using the notions of biopolitics and governmentality.
