A visão dos professores quanto ao processo de ensino e de aprendizagem do basquetebol nas aulas de educação física: a realidade de Volta Redonda/RJ

The present study has as its main purpose the investigation of teachers'view concerning the teaching and learning of basketball in Physical Education classes in a school setting. The selected teachers who participated in this survey come from public and private institutions in the city of Volta Redonda, RJ, Brazil, teaching 6th-9th grade classes of elementary school. This was a quantitative and qualitative study with content analysis. Data collection included interviewing 60 teachers who provided their opinions on the issue investigated. Development of basketball was investigated not only as a content for the Physical Education classes, but also as a dimension that goes beyond school boundaries, where that sport plays an important role in society. Joint actions to provide the opportunity for basketball to grow as a content for Physical Education classes may represent a way to describe its implementation in all contexts, although the importance of this discipline in the school setting should not be disregarded in favor of obtaining results in sports competitions.

Práticas corporais e cristianismo: relações e preceitos

This study, qualitative, aimed to try to understand relations and premises involving bodily practices and Christianity. The study was conducted by means of literature, focusing the themes of religion and the body along with issues involving Christian ethics, through its principles and values, which must be practiced, not only within the church, but even within the society, in sports, in schools. Based on the literature review, it can be seen that the body practices have a direct relationship with the Christian religion, in the aspects involving the ethics of their practices, experiences, thoughts, attitudes, principles and values, in addition to cultural training and body of students from different schools, in which the physical education professional is directly involved with the bodily practices. As conclusions, it was noted the probability of a harmonious and fundamental relationship between religion and bodily practices, along with a productive association between Christianity and society, helping the individual in its ethical and social formation. We suggest new approaches to the formation of the professional of Physical Education, in order take into consideration these aspects involving religiosity

Estilo de liderança de técnicos de futebol

Psychological factors are gaining more space in sports, and increasingly common related professional psychology are inserted in the sporting context. Seeking a better understanding of the manifestations of leadership in football between technicians of different categories this study aimed to verify whether there is a preferred style of leadership among the football coaches and if there are differences between the leadership style ideal and real seconded by same. The methodology used the Search Specification (CERVO and BERVIAN, 2004) relying on the implementation of the Revised Leadership Scale for Sport (ELRE), ideal and real versions Profile, With the participation of twenty football coaches in the field (n = 20), working in teams of males in the City of São Bernardo do Campo - SP, and to process the data we calculated the Cronbach alpha to verify the reliability of the scale, and the average of the results relying on the software application SPSS version 17.0 for Windows. Of the total participants 30% have a degree in Physical Education and are inserted in the football an average of 8 years in different roles and the prevalence of autocratic decision-making model, with an alpha of 0.87 results in the ideal profile and the actual profile of alpha 0.86 , So the scale is stable and reliable. We conclude that the model of autocratic decision not differ very significantly compared to the model of democratic decision. Regarding the interaction with the group of technicians the situational model is highlighted in research showing that technicians take into account situational factors.

Participação de mulheres na gestão esportiva: uma revisão sistemática

During the last decades of the XX century occurred several demographic, cultural and social changes that directly affected the inclusion of women in the labor market. However many of them have found and still find barriers to work in various fields of endeavor and in the case of this study, the sports management. The purpose of this study was to assess through a systematic review, the participation of women in sports management, listing the main characteristics, challenges and difficulties. The research consisted of a systematic review of studies that discuss the thematic related to the participation of women in sport management in Brazil, including the Google Scholar database. The key words used and that generated proceeds were woman, sports management and women in sports administration. In the discussion and results has been possible to list the insert forms in a management position, the main ones being: by invitation, conduction or family relationship. The arguments about the limited participation of women in sports management and their encountered barriers are justified because there is a male domain and prejudice, resulting often the career waiver for these women. The profile of the sporting managers has found a predominance of men aged between 30-49 years old. For unavailability of articles, the present study was restricted to use only one database. In short, there is a lacuna in studies on women's participation in the administration or sporting management, with a prevalence of literature review articles. To expand overview on this issue would be important to carry out quantitative studies. It was concluded that the difficulty of women entering in sports management still seems to be a current problem and can only be minimized from a greater attention from the scientific community. It is suggested to carry out further studies that address more deeply the reasons for this disparity, aimed at proposing specific changes to the...

Liderança no futebol: uma relação entre técnico e atleta

The sports psychology today is increasingly inserted in the day-to-day of sports teams, and it happens because the technical, tactical and physical levels are too equal. Through sports psychology we try to understand the behavior of each athlete and the group itself to achieve a better performance in training and competition. Thus, within the sports psychology we have the leadership phenomenon that has been constantly studied in order to understand the relationship between coach and athlete in the sports context. The objective of this study is to verify in the literature issues related to leadership in sports groups, as well as analyze how leadership is treated by coaches and seen by the athletes and also see how the leadership is specifically manifested in the football environment. As a methodological procedure was performed an analytical research in which a bibliographic review was developed. We conclude that in sports in general, there is a preference by part of the athletes for coaches with a training-education behavior, in what he cares about the development of the technical and tactical aspects of your team or athlete. And in the context of football that the most dominant style of leadership behavior of coaches is the autocratic and by the athletes, they considered most important the education-training dimension as ideal behavior of their coaches leadership

Análise de um processo avaliativo do jogo de handebol

Handball is a team sport invasion, much practiced in Brazilian schools. There are different teaching methods of team sport, and with them different evaluation methods, this study aims to analyze the shared evaluation process of building course with students of a handball design of a municipal school in Bauru in sports initiation and at the end submit an evaluation process. For this study students of a municipal school participants handball classes in the opposite time of curricular classes underwent an interview, besides having been recorded them playing a handball game with number of small participants at the beginning of the post holiday classes July and another three months later as a form of evaluation. After reviewing the videos and interviews, it was concluded that some students had a game performance improves when they were part of the attack, and also had a behavioral improvement, both from actions taken in the game, as respect to the next, thus interpreted by the students themselves. Although it is a difficult task to analyze and quantify the performance of students in Physical Ed classes can complete some improvements, moreover is valid Professor hear the views of students to understand the vision that students have of themselves during the game

Incidence of adverse events associated with percutaneous muscular biopsy among healthy and diseased subjects

The development of the percutaneous muscle biopsy technique is recognized as one of the most important scientific contributions in advancing our understanding of skeletal muscle physiology. However, a concern that this procedure may be associated with adverse events still exists. We reported the incidence of adverse outcomes associated with percutaneous muscle biopsy in healthy and diseased subjects. Medical records of 274 volunteers (496 muscle biopsies) were reviewed. This included 168 healthy subjects (330 muscle biopsies) as well as 106 chronically ill patients (166 muscle biopsies). This latter group encompassed patients with type II diabetes (n=28), osteoarthritis (n=39), inclusion body myositis (n=4), polymyositis (n=4), and chronic heart failure (n=31). The most common occurrences were pain (1.27%), erythema (1.27%), and ecchymosis (1.27%). Panic episode, bleeding, and edema were also reported (0.21%, 0.42%, and 0.84%, respectively), while infection, hematoma, inflammation, denervation, numbness, atrophy, and abnormal scarring were not verified. The percent of incidents did not differ between healthy and ill individuals. In conclusion, the incidence of complications associated with percutaneous muscle biopsy is scarce and of minor clinical relevance. Additionally, the rate of adverse events is comparable between healthy and chronically ill subjects.

LAURENTINO, G. C., C. UGRINOWITSCH, H. ROSCHEL, M. S. AOKI, A. G. SOARES, M. NEVES JR, A. Y. AIHARA, A. DA ROCHA CORREA FERNANDES, and V. TRICOLI. Strength Training with Blood Flow Restriction Diminishes Myostatin Gene Expression. Med. Sci. Sports Exerc., Vol. 44, No. 3, pp. 406-412, 2012. Purpose: The aim of the study was to determine whether the similar muscle strength and hypertrophy responses observed after either low-intensity resistance exercise associated with moderate blood flow restriction or high-intensity resistance exercise are associated with similar changes in messenger RNA (mRNA) expression of selected genes involved in myostatin (MSTN) signaling. Methods: Twenty-nine physically active male subjects were divided into three groups: low-intensity (20% one-repetition maximum (1RM)) resistance training (LI) (n = 10), low-intensity resistance exercise associated with moderate blood flow restriction (LIR) (n = 10), and high-intensity (80% 1RM) resistance exercise (HI) (n = 9). All of the groups underwent an 8-wk training program. Maximal dynamic knee extension strength (1RM), quadriceps cross-sectional area (CSA), MSTN, follistatin-like related genes (follistatin (FLST), follistatin-like 3 (FLST-3)), activin IIb, growth and differentiation factor-associated serum protein 1 (GASP-1), and MAD-related protein (SMAD-7) mRNA gene expression were assessed before and after training. Results: Knee extension 1RM significantly increased in all groups (LI = 20.7%, LIR = 40.1%, and HI = 36.2%). CSA increased in both the LIR and HI groups (6.3% and 6.1%, respectively). MSTN mRNA expression decreased in the LIR and HI groups (45% and 41%, respectively). There were no significant changes in activin IIb (P > 0.05). FLST and FLST-3 mRNA expression increased in all groups from pre- to posttest (P < 0.001). FLST-3 expression was significantly greater in the HI when compared with the LIR and LI groups at posttest (P = 0.024 and P = 0.018, respectively). GASP-1 and SMAD-7 gene expression significantly increased in both the LIR and HI groups. Conclusions: We concluded that LIR was able to induce gains in 1RM and quadriceps CSA similar to those observed after traditional HI. These responses may be related to the concomitant decrease in MSTN and increase in FLST isoforms, GASP-1, and SMAD-7 mRNA gene expression.

Effect of N-acetylcysteine on markers of skeletal muscle injury after fatiguing contractile activity

The effects of N-Acetylcysteine (NAC), an unspecific antioxidant, on fatiguing contractile activity-induced injury were investigated. Twenty-four male Wistar rats were randomly assigned to two groups. The placebo group (N=12) received one injection of phosphate buffer (PBS) 1 h prior to contractile activity induced by electrical stimulation. The NAC group (NAC; N=12) received electrical stimulation for the same time period and NAC (500 mg/kg, i.p.) dissolved in PBS 1 h prior to electrical stimulation. The contralateral hindlimb was used as a control, except in the analysis of plasma enzyme activities, when a control group (rats placebo group not electrically stimulated and not treated) was included. The following parameters were measured: tetanic force, muscle fatigue, plasma activities of creatine kinase (CK) and lactate dehydrogenase (LDH), changes in muscle vascular permeability using Evans blue dye (EBD), muscle content of reactive oxygen species (ROS) and thiobarbituric acid-reactive substances (TBARS) and myeloperoxidase (MPO) activity. Muscle fatigue was delayed and tetanic force was preserved in NAC-treated rats. NAC treatment decreased plasma CK and LDH activities. The content of muscle-derived ROS, TBARS, EBD and MPO activity in both gastrocnemius and soleus muscles were also decreased by NAC pre-treatment. Thus, NAC has a protective effect against injury induced by fatiguing contractile activity in skeletal muscle.

Esteróides anabolizantes: do atleta ao cardiopata

Devido às suas ações anabólicas, os esteroides anabolizantes (EAs) são usados por atletas para melhorar o desempenho físico, mas seu uso vem sendo crescente também entre indivíduos que praticam atividade física como forma de lazer, com o simples objetivo de melhorar a aparência física. Os usuários de EAs fazem uso de doses suprafisiológicas, que podem levar ao aparecimento de sérios efeitos colaterais, como os prejuízos cardiovasculares, o que faz do uso indiscriminado e abusivo um importante problema de saúde publica. Com isso, a presente revisão tem como objetivo despertar o interesse dos leitores e professores de Educação Física pelo EA e os perigos, muitas vezes ocultos, associados ao uso indiscriminado dessas drogas, principalmente sobre o sistema cardiovascular.
