Pedagogia do esporte: livro didático aplicado aos jogos esportivos coletivos

The study deals with the pedagogical possibilities of text books as a resource for Physical Education (PE) classes based on sports, specifically team sports. It started from a bibliographical review on the cited terms and after that we advanced our studies in order to propose a didactic text book on Team Sports for PE classes considering two benchmarks: one technical-tactic and the other social-educational. In order to do so, we used methods from linguistics, and the development of a Didactic Sequence allowed the selection and distribution of the contents to be presented in the book in an orderly and judicious way. The focus in Team Sports is justified by its social-cultural insertion and by the need to transform recent studies into new pedagogical procedures for practicing them. The didactic text book, as well as the adequate preparation of the professionals who will use it, is pointed out as facilitator in the process of teaching, experiencing and learning team sports.

Interferência do bullying no esporte de alto rendimento

Examine the phenomenon of bullying behavior that makes people teased, laughter, sarcasm, irony, among other types of attacks. This is not only physically, but with moral violence, emotional or psychological. When there is an effective intervention against bullying, all individuals in the group start to suffer with this situation, which can lead to psychological disorders, hampering the progress of relations as well as team sports, over a period of training and competition. This article analyzed a sample of athletes in order to find behaviors that characterize the extent of bullying and can see the consequences of it, as early drop out. Through the results it was concluded that the actions that characterize bullying are present in very high performance football and may even lead to drop out the sport. We also evaluate the environments frequented by teams can become enhancers of this phenomenon, they are times when athletes have a living space and one that may become amenable to the events, plus the fact that many athletes have already thought about leaving the sport because to bullying

Análise do futebol feminino nos periódicos da área

This paper is a literature review where we analyzed articles within the five magazines Top-rated Physical Education, seeking as a central theme the women's game regarding the Physical Education classes. According to the literature studied approach the position of women within football, recall some historical facts as well as girls are seen within football in the school environment, where we can cite the difficulties that teachers still have mixed classes when they are given within physical education, making seek alternatives to the practice of team sports, focusing on football practice

Avaliação das variáveis técnicas no contexto esportivo

Assessment is a theme explored in various areas of human performance, particularly for the analysis of an athlete performance and/or all team members in game situation. Assessment requires different tests and models to quantify strengthens and weaknesses of an athlete and of the team. With that in hand, it is possible to develop an intervention program, with consequent improvement of techniques and tactics play systems. The present study aimed to identify, in the literature, the athlete's performance ratings and of the team in game situation for team sport. Based on the literature review, we propose a set of variables to include in an instrument for basketball performance assessment. The methodology for the present study involved a collection of materials, including scientific articles, books, websites, academic papers. The present research comprises the concepts and definitions related to: team sport; the relevance of game analysis and its development; the advantages and disadvantages of different assessment techniques, particularly in team sports; and lastly, the instruments used for assessment in the context of team sport athletes. From the literature review we propose a set of variables that may be useful to consider in an assessment instrument for basketball performance

Monitoring internal load parameters during simulated and official basketball matches

Moreira, A, McGuigan, MR, Arruda, AFS, Freitas, CG, and Aoki, MS. Monitoring internal load parameters during simulated and official basketball matches. J Strength Cond Res 26(3): 861-866, 2012-The purpose of this study was to compare the internal load responses (session rating of perceived exertion [RPE] and salivary cortisol) between simulated and official matches (SM and OM). Ten professional basketball players participated in 2 OMs and 2 SMs during the competition season. Subjects provided saliva samples 30 minutes before the prematch warm-up (PRE) and 10 minutes after the end of the match. Session RPE (CR-10 scale) was assessed 30 minutes after each match. The results from the 2-way analysis of variance showed significant differences for post-OM salivary cortisol as compared with pre-OM values (p < 0.05). No changes were observed for cortisol during the SM. Before the OM, a significant difference in salivary cortisol was observed as compared with pre-SM values (p < 0.05). Moreover, the OM session RPE was significantly greater than that of SM. There was a significant correlation between session RPE and cortisol changes (r = 0.75). In summary, the results of this study showed a greater magnitude of cortisol and session RPE responses after OM as compared with that after SM confirming the hypothesis that a real competition generates a greater stress response than a simulated condition does. The anticipatory effect was also observed in the OM. In addition, the results indicate that session RPE seems to be a viable tool in monitoring internal loads, and the results are useful in providing a better understanding of internal loads imposed by basketball training and competitions. The precise monitoring of these responses might help the coaches to plan appropriate loads maximizing recovery and performance.

Elementos estruturais de um modelo formal dos esportes coletivos de invasão

O desenvolvimento de um modelo formal da estratégia e da dinâmica do jogo constitui uma contribuição científica original no contexto dos esportes coletivos de invasão. O procedimento construtivo de uma estratégia definido no modelo é composto de cinco conjuntos de elementos ordenados em níveis hierárquicos, que suportam o desenho de estratégias capazes de orientar adequadamente uma equipe em um jogo. Uma vez definido o modelo da estratégia, a formalização da dinâmica do jogo permite sua contextualização no momento de sua aplicação para orientar os jogadores no confronto. O jogo teve sua estrutura decomposta e suas propriedades dinâmicas fundamentais foram definidas. Dessa forma, a modelagem da dinâmica da oposição e da estratégia se complementam, pois definem os momentos nos quais a informação estratégica é utilizada pelos jogadores. A estrutura formal apresentada inaugura uma linha de pesquisa que poderá contribuir para limitar a subjetividade na definição dos critérios de análise de futuros desenhos experimentais, levando à interpretações e comparações mais acuradas dos resultados dos estudos.

The association between extra-curricular sport participation and social anxiety symptoms in children

Social anxiety is a common psychological complaint that can have a significant and long-term negative impact on a child’s social and cognitive development. In the current study, the relationship between sport participation and social anxiety symptoms was investigated. Swiss primary school children (N = 201), parents, and teachers provided information about the children’s social anxiety symptoms, classroom behavior, and sport involvement. Gender differences were observed on social anxiety scores, where girls tended to report higher social anxiety symptoms, as well as on sport activity, where boys engaged in more sport involvement. MANCOVAs with gender as covariant showed no differences in social anxiety symptoms between children involved in an extracurricular sport and those not engaged in sport participation. Nevertheless, children engaged in team sports displayed fewer physical social anxiety symptoms than children involved in individual sports.

Impairments of peripheral motion change detection during smooth pursuit eye movements

Introduction: In team sports the ability to use peripheral vision is essential to track a number of players and the ball. By using eye-tracking devices it was found that players either use fixations and saccades to process information on the pitch or use smooth pursuit eye movements (SPEM) to keep track of single objects (Schütz, Braun, & Gegenfurtner, 2011). However, it is assumed that peripheral vision can be used best when the gaze is stable while it is unknown whether motion changes can be equally well detected when SPEM are used especially because contrast sensitivity is reduced during SPEM (Schütz, Delipetkose, Braun, Kerzel, & Gegenfurtner, 2007). Therefore, peripheral motion change detection will be examined by contrasting a fixation condition with a SPEM condition. Methods: 13 participants (7 male, 6 female) were presented with a visual display consisting of 15 white and 1 red square. Participants were instructed to follow the red square with their eyes and press a button as soon as a white square begins to move. White square movements occurred either when the red square was still (fixation condition) or moving in a circular manner with 6 °/s (pursuit condition). The to-be-detected white square movements varied in eccentricity (4 °, 8 °, 16 °) and speed (1 °/s, 2 °/s, 4 °/s) while movement time of white squares was constant at 500 ms. 180 events should be detected in total. A Vicon-integrated eye-tracking system and a button press (1000 Hz) was used to control for eye-movements and measure detection rates and response times. Response times (ms) and missed detections (%) were measured as dependent variables and analysed with a 2 (manipulation) x 3 (eccentricity) x 3 (speed) ANOVA with repeated measures on all factors. Results: Significant response time effects were found for manipulation, F(1,12) = 224.31, p < .01, ηp2 = .95, eccentricity, F(2,24) = 56.43; p < .01, ηp2 = .83, and the interaction between the two factors, F(2,24) = 64.43; p < .01, ηp2 = .84. Response times increased as a function of eccentricity for SPEM only and were overall higher than in the fixation condition. Results further showed missed events effects for manipulation, F(1,12) = 37.14; p < .01, ηp2 = .76, eccentricity, F(2,24) = 44.90; p < .01, ηp2 = .79, the interaction between the two factors, F(2,24) = 39.52; p < .01, ηp2 = .77 and the three-way interaction manipulation x eccentricity x speed, F(2,24) = 3.01; p = .03, ηp2 = .20. While less than 2% of events were missed on average in the fixation condition as well as at 4° and 8° eccentricity in the SPEM condition, missed events increased for SPEM at 16 ° eccentricity with significantly more missed events in the 4 °/s speed condition (1 °/s: M = 34.69, SD = 20.52; 2 °/s: M = 33.34, SD = 19.40; 4 °/s: M = 39.67, SD = 19.40). Discussion: It could be shown that using SPEM impairs the ability to detect peripheral motion changes at the far periphery and that fixations not only help to detect these motion changes but also to respond faster. Due to high temporal constraints especially in team sports like soccer or basketball, fast reaction are necessary for successful anticipation and decision making. Thus, it is advised to anchor gaze at a specific location if peripheral changes (e.g. movements of other players) that require a motor response have to be detected. In contrast, SPEM should only be used if a single object, like the ball in cricket or baseball, is necessary for a successful motor response. References: Schütz, A. C., Braun, D.

Théorie des jeux expérimentale & action motrice

How do sportspeople succeed in a non-collaborative game? An illustration of a perverse side effect of altruism Are team sports specialists predisposed to collaboration? The scientific literature on this topic is divided. The present article attempts to end this debate by applying experimental game theory. We constituted three groups of volunteers (all students aged around 20): 25 team sports specialists; 23 individual sports specialists (gymnasts, track & field athletes and swimmers) and a control group of 24 non-sportspeople. Each subgroup was divided into 3 teams that played against each other in turn (and not against teams from other subgroups). The teams played a game based on the well-known Prisoner's Dilemma (Tucker, 1950) - the paradoxical "Bluegill Sunbass Game" (Binmore, 1999) with three Nash equilibria (two suboptimal equilibria with a pure strategy and an optimal equilibrium with a mixed, egotistical strategy (p= 1/2)). This game also features a Harsanyi equilibrium (based on constant compliance with a moral code and altruism by empathy: "do not unto others that which you would not have them do unto you"). How, then, was the game played? Two teams of 8 competed on a handball court. Each team wore a distinctive jersey. The game lasted 15 minutes and the players were allowed to touch the handball ball with their feet or hands. After each goal, each team had to return to its own half of the court. Players were allowed to score in either goal and thus cooperate with their teammates or not, as they saw fit. A goal against the nominally opposing team (a "guardian" strategy, by analogy with the Bluegill Sunbass Game) earned a point for everyone in the team. For an own goal (a "sneaker" strategy), only the scorer earned a point - hence the paradox. If all the members of a team work together to score a goal, everyone is happy (the Harsanyi solution). However, the situation was not balanced in the Nashian sense: each player had a reason to be disloyal to his/her team at the merest opportunity. But if everyone adopts a "sneaker" strategy, the game becomes a free-for-all and the chances of scoring become much slimmer. In a context in which doubt reigns as to the honesty of team members and "legal betrayals", what type of sportsperson will score the most goals? By analogy with the Bluegill Sunbass Game, we recorded direct motor interactions (passes and shots) based on either a "guardian" tactic (i.e. collaboration within the team) or a "sneaker" tactic (shots and passes against the player's designated team). So, was the group of team sports specialist more collaborative than the other two groups? The answer was no. A statistical analysis (difference from chance in a logistic regression) enabled us to draw three conclusions: ?For the team sports specialists, the Nash equilibrium (1950) was stronger than the Harsanyi equilibrium (1977). ?The sporting principles of equilibrium and exclusivity are not appropriate in the Bluegill Sunbass Game and are quickly abandoned by the team sports specialists. The latter are opportunists who focus solely on winning and do well out of it. ?The most altruistic players are the main losers in the Bluegill Sunbass Game: they keep the game alive but contribute to their own defeat. In our experiment, the most altruistic players tended to be the females and the individual sports specialists

La resistencia especial en el fútbol

La finalidad de esta tesis es establecer un análisis de la metodología de entrenamiento de la resistencia especial en el futbolista. Su objetivo no está vinculado a realizar propuestas prácticas de entrenamiento, sino más bien, se tratará de abordar una posible justificación fisiológico - metabólica, a partir de la relevancia bioenergética de la creatina, en función de la creciente especialización que debe ir adquiriendo el proceso del entrenamiento deportivo a largo plazo, enfocado al logro de altos rendimientos deportivos. A partir del análisis de conceptos terminológicos de referencia, se asienta la idea general de este trabajo, es decir, la estructuración y desarrollo de la resistencia en los deportes de conjunto, como el fútbol. Los pilares de una adecuada planificación son el conocimiento y la aplicación de distintas leyes y principios del entrenamiento deportivo y su relación con los distintos medios y métodos de entrenamiento, como así también, los efectos de adaptación que provocan. Por lo tanto, a partir del análisis de los requerimientos morfológicos - funcionales de las competiciones de elite en fútbol, se pueden elaborar modelos que servirán de base y como objetivo final al cual debe ser orientado el proceso de entrenamiento. Es decir, que un entrenamiento multianual con miras a la formación de futbolistas de elite, debe respetar la especialización creciente de las cargas de entrenamiento, estableciendo una sucesión metodológica adecuada en función de los objetivos de cada etapa. En función de lo expuesto, se realiza un análisis que va desde la resistencia como capacidad física y su metodología de entrenamiento, recorriendo distintos conceptos y manifestaciones, pasando por el análisis de distintas zonas de intensidad o áreas funcionales, y desembocando en la metodología de entrenamiento intermitente de la resistencia o resistencia especial -en los deportes de conjunto-. Y es a partir de todo el análisis precedente que estamos en condiciones de abordar el entrenamiento específico en el fútbol, y más detalladamente la resistencia específica o intermitente que requiere este deporte. El entrenamiento intermitente puede ser considerado como una metodología cuyo énfasis es puesto en modificaciones que se producen a nivel muscular, por sobre factores centrales de rendimiento, presentándose como una variante óptima para el entrenamiento de la resistencia muscular local y específica del futbolista. Básicamente, el entrenamiento intermitente actuaría sobre dos puntos centrales: la mejora del sistema shuttle de la CrP, y sobre la rapidez de entrega de oxígeno al inicio del ejercicio. Aquí aparece la importancia de la suplementación con Cr: que al aumentar las concentraciones del sustrato, y junto con el entrenamiento, que mejora las reacciones enzimáticas implicadas, potenciaría las mejoras buscadas con este tipo de metodología. Queda por determinar cual es el preciso mecanismo de acción por el cual la recuperación de los fosfatos altamente energéticos se produce: si por biogénesis mitocondrial en las fibras reclutadas - generalmente FT -; o mediante el sistema de proteínas transportadoras de Cr - destacando la importancia de las ST - o por algún otro mecanismo no conocido. Su descubrimiento permitiría direccionar más precisamente el entrenamiento deportivo.

La educación virtual antidoping como estrategia para desarrollar la cultura del juego limpio en el deporte mexicano : Un estudio de género

El propósito del estudio fue analizar el nivel de conocimiento y dominio sobre el doping que tienen las deportistas élite en México, para emprender acciones que permitan educar a los deportistas y su equipo de entrenamiento en el juego limpio, a través de acciones psicopedagógicas que faciliten un aprendizaje significativo, evitando que las deportistas usen de manera voluntaria o involuntaria sustancias y métodos prohibidos. Las pregunta principal que orientó la investigación fue la siguiente: ¿Qué nivel de conocimiento y dominio sobre el doping tienen las deportistas élite en México?. Para la investigación de campo, se elaboró un cuestionario de 22 preguntas para explorar el nivel de conocimiento y dominio que tenían los deportistas considerados élite por pertenecer a la selección estatal o nacional de los deportes de gimnasia olímpica, tiro con arco y hockey sobre pasto. Las respuestas encontradas demuestran que en algunos aspectos existe desconocimiento en materia de dopaje, y se devela la necesidad de profundizar en el programa de educación antidoping. Se manifiesta que la ignorancia que existe en diferentes aspectos, pone en riesgo a los deportistas en el uso inconsciente de sustancias y métodos prohibidos en el deporte
