Alteração da impulsão vertical após o período competitivo em atletas de profissionais de futebol

Change on vertical jump after competitive period in professionals soccer players. Brazilian Journal of Biomotricity, v. 4, n. 2, p. 140-147, 2010. Soccer is a sport that demands different intensities of run, with decisive actions of a match being held in maximum intensity. Vertical jump test is widely used in soccer players due to the strong relationship with speed and agility. Futhermore, there are little information about change on vertical jump after the competitive season in soccer players. The aim of this study was to analyze change on vertical jump after the competitive season in professional soccer players. Took part in this study 21 male athletes (20.82 ± 3.16 years, 72.28 ± 8.74 kg and 179.91 ± 6.14 cm) subscribers to the 4th division of the Paulista championship of 2009. The competitive season had a duration of 20 weeks, with a total of 20 official matchs done. The test used was the counter-movement vertical jump (VJ), that was performed in the first (PRE) and last (POS) training session of the competitive period. After confirmation of data normality by Kolmogorov-Smirnov, the inferential analysis of the results of VJ between PRE and POS was performed using the paired t-test, considering the significance level of 5%. There was a significant increase (p<0,05) on VJ after the competitive period (PRE=54,19±4,46 and POS=57,94±5,23). According to the results of this study, it is possible to increase the performance of VJ in professional soccer players after the competitive period of 20 weeks duration.

Avaliação da ingestão protéica e do balanço e do balanço nitrogenado em universitários praticantes de musculação

The alimentation of fitness people is fundamental by health. This study it has for objective to evaluate of quali-quantitative form the proteic-caloric ingestion, the nitrogen balance and its relation caloric ingestion/estimated metabolic rate, in colleges student practicing of body-building. Eleven body-builders student (18 until 30 years old), both sex, had been analyzed. The attainment of data used an alimentary register, and the gotten information were analyzed together with the nitrogen balance from 24 hours of piss collection. We observed that the nitrogen balance of individuals that make use of some protein supplement is significantly bigger than individuals that do not consume no type of it. This because, the percentile caloric obtained from protein ingestion is significantly raised, and this associate to the caloric ingestion in this group also is raised, determines the obtained results.

Educação física escolar: estado da arte e direções futuras

The aim of this paper is to characterize and discuss the School Physical Education as a profession and subarea of research in the broader academic fi eld of Physical Education and educational research. To do that, it initially defi nes the difference between research in School Physical Education from research about School Physical Education, and point out the themes and research hypotheses for this subarea. It also analyses 289 articles characterized as research in School Physical Education, published in 11 Brazilian periodicals, classifying them in the following categories: “level of schooling”, “bodily practice” and “theme”. The results indicate that the majority of studies are carried out in elementary school, in “games” and “sports”, and in descriptive and interpretative research in School Physical Education practices in several dimensions and interrelations. In conclusion, it points to the need to a focus in the research in teaching, the implementation of public curricula, and teacher education. Finally, it alerts to the need for Brazilian postgraduate programs in the academic fi eld of physical education to invest more in research in School Physical Education subarea.

Profissão professor: olhares de professores de Educação Física escolar

No presente artigo abordou-se o processo de profissionalização e formação acadêmica em Educação Física, buscando evidenciar as implicações surgidas em decorrência da trajetória de formação do professor dessa área. Embora esta se configure também como uma profissão docente, sua história apresenta particularidades com relação às outras áreas da docência escolar. Diante disto, o objetivo do estudo consistiu em estabelecer um diálogo entre as dimensões da profissionalização e da formação de professores de Educação Física para auxiliar na compreensão da situação atual da disciplina e do processo de construção da profissionalidade docente. Em articulação com a revisão da literatura foram discutidas as concepções de um grupo representativo de professores de Educação Física escolar da rede pública de ensino estadual de São Paulo - Brasil, coletadas por intermédio de entrevistas semi-estruturadas. Constatou-se que para os depoentes persistem, ainda, equívocos no imaginário da comunidade escolar a respeito do valor e da função da disciplina Educação Física para o desenvolvimento do alunado, sendo a disciplina freqüentemente indicada como sinônimo de esporte. Entende-se que a compreensão da trajetória dessa profissão até o momento (que pode ser considerada uma profissão recente), assim como os fatores que contribuíram para a desvalorização do professor da área, são importantes recursos para começar a pensar o futuro. Concluiu-se que cabe, especialmente, à formação docente constituir-se num componente que efetivamente contribua para a (re)construção da profissionalidade do professor e para a legitimação da disciplina Educação Física no campo educacional.

A influência da orientação motivacional durante o treinamento de atletas iniciantes no tênis de campo

The motivation in the sport has been one of the most studied subjects nowadays, as much that some authors say that the motivation is the base for the success of an athlete, that is, the psychological part must also well be stimulated so that if it reaches the maximum level of concentration during a game it will obtains the expected result. Tennis is one of the sports that more grew in recent years, and together with this fast ascension also increased the number of interested in researching in this area of the Psychology of the Sport. The present study has as objective to begin the adaptation and validation of the interest scale and to analyze the influence of the motivational orientation of the athletes in the sportive performance of the Tennis through the application of scale Teosq – Task and Ego Orientation in Sport Questionnaire (DUDA, 1992), translated, adapted and validated by Hirota and De Marco (2006), where we can identify if the individual is guided for a task or an ego’s goal. This research was carried through in a situated academy of Tennis in the City of Cotia – SP – Brazil, counting on the participation of 20 citizens with age between 09 and 18 years of both the practicing sexes of Tennis. The calculation of the Alpha Coefficient of Cronbach was adopted as statistical method, in order to identify the trust worthy and validity of the instrument beyond the average of each orientation, to be able to verify the athlete’s motivational orientation. For the analysis of the results, the Alpha Coefficient was observed high, compared with previous studies, reaching values of orientation for the ego of 0,90, and 0,70 of orientation for task. They had been registered the following averages, 4,20 (+0,93) and 2,42 (+0,85), respectively of orientation for task and ego. With those results we can point that, the scale applied with the proposal to identify the motivational orientation of the athletes of Tennis, revealed efficiency, and trust worthy in its application, and in accordance with the results, the athletes are guided for task, revealing self-determination, selfconfident, more creative and they judge its success for the quality of the carried through work.

O tipo de trajetória não afeta o controle visual da freada em ciclistas

Braking visual control was studied in recreational cyclists through the manipulation of bicycle’s velocity at braking initiation (low, medium, and high) and approaching trajectory (straight and curved) with respect to a stationary obstacle. The hypothesis was that the type of trajectory, exclusively or interacting with initial velocity, would affect time to collision visual information (tau margin) and its fi rst derivative in time (tau-dot), respectively, in the onset and during braking. The results revealed that velocity affected signifi cantly tau margin while tau-dot remained unaltered independently of condition. The type of trajectory clearly did not affect the visual control of braking in cyclists.

Relação dos saltos vertical, horizontal e sêxtuplo com a agilidade e velocidade em crianças

The aim of the present study were: 1) To verify the relationship of vertical, horizontal and sextuple jumps with agility and velocity of 5, 10 and 25 m; 2) To verify the capacity of these jumps to predict the agility and 5, 10 and 25 m velocity performance in children. Twenty eight boys (9.47 ± 0.64 years) and thirty girls (9.69 ± 0.70 years) were evaluated. The correlation values between agility and velocity on 5, 10 and 25 m velocity were, respectively, r = 0.63, 0.51, 0.44 and 0.64 with vertical jump, r = 0.68, 0.62, 0.28 and 0.62 with sextuple jump, and r = 0.60, 0.50, 0.26 and 0.57 with horizontal jump. The vertical and sextuple jumps were able to predict the agility and 25 m velocity performance (p < 0.05). Furthermore, they demonstrated capacity to predict 5 and 10 m velocity, respectively (p < 0.05). The vertical and sextuple jump tests may be used for assessment and control of training with children practicing activities that require agility and velocity, since both jumps predicted the agility and velocity performance, which did not occur with the horizontal jump.

Dilemas contemporâneos da profissão professor: perspectivas de professores(as) de Educação Física da rede pública estadual de São Paulo

The purpose of this article is to reflect on the movement of professionalization of teaching, emphasizing the importance given to vocational training (initial and continuing) in this context. The research is qualitative in that it sought in the testimonies of eight physical education teachers, the São Paulo public state educacional, to elucidate the reflections from the literature review. It was found that although the social and political discourses glimpse the teacher as the main agent of social transformation, this possibility still presents far for this group, especially in view of the heavy workload and poor remuneration, hindering investment in training. It was concluded that this group is immersed in speeches ambiguous and contradictory processes, characterizing a movement of professionalization and concomitant deprofessionalization in teaching.
