Interferência da torcida na ansiedade e agressividade de atletas adolescentes

O presente trabalho surge em função de buscar um melhor entendimento sobre o papel da torcida, diante dos estados emocionais dos atletas, em especial da ansiedade e da agressividade. Baseado em vasta revisão de literatura, que apresenta as diversas concepções conceituais aqui estudado (adolescência, agressão, ansiedade e torcida) e seus desdobramentos, o estudo assume a vertente da pesquisa qualitativa, optando pela pesquisa participante, como estratégia de verificação. Assim, interessou-se em estudar os aspectos relativos à ação da torcida e sua interferência no comportamento agressivo e ansioso do jogador jovem, que participa de uma modalidade federada, afim de verificar se o aumento da ansiedade e da agressividade, no momento esportivo, reflete o aumento de pressão que se exerce exteriormente. Considerou-se torcida aquele público presente, que assiste aos confrontos esportivos, nas figuras de pais, fãs, familiares e crônica esportiva e o público ausente, como os pais e a imprensa, que ficam no aguardo do resultado, em seus ambientes próprios. Esta pesquisa, exploratória, analisou o contexto esportivo competitivo de atletas das modalidades de basquetebol, futebol de salão, voleibol, handebol, atletismo e natação, observando, entrevistando e coletando falas e expressões que pudessem, após rigorosa categorização, oferecer subsídios para um replanejamento na conduta esportiva de adolescentes. Constatou a grande influência do público, em especial a dos pais, com muito determinismo, seguido do profissional da área esportiva, conforme indicam outros estudos. Explicita a questão da causa efeito no que diz respeito a ansiedade e agressão, oferecendo propostas para trabalhos que possibilitem outra abordagem ou favoreçam outras interferências por parte do público presente.

A indução da potencialização pós-ativação através dos saltos: pliométrico e vertical

The Post-Activation Potentiation (PAP) offers a proposal to optimize the production of strength and muscular power when performing exercises near maximum to actions previously assessed . The present study aims to show the activation process of postactivation potentiation (PAP) through vertical and plyometric jumps, and explain the user function of these movements. The ratio of post-activation potentiation resulting from plyometric and vertical jumps and explosive strength in the lower limbs aims to improve the potency and maximal strength, proven through studies and protocols detailed here. The results of this research come can be applied both for athletes and for individuals with experience in strength training and jumps (sports like volleyball, basketball and handball). The study was conducted through a literature review, conducted in scientific journals indexed in major databases (PubMed, ISI-Web of Science, SCIELO), books and academic papers (theses and dissertations)

Jogo de handebol e futsal na escola: possibilidades e limites pedagógicos

Sports team, specifically soccer and handball, has traditionally composing the physical education school contents as a curriculum component. There are several criticisms to extend this approach beyond the sportive discourse. While we recognize this need for expansion, we believe that the methodological endeavors to teach these sports content are still very poor, requiring, therefore, studies that guide us in changing not only contents but also the way of teaching it, which implies new e teaching, pupils and teaching relationship perspective. In this sense, the objective of this study was to identify and analyze, from a sports team tactics teaching approaches of invasion, the demonstrations by students, the phases of handball and soccer games, as well as the elements/dynamic structural, functional and operational in the same school environment. Given this objective, qualitative research, specifically, collaborative action research, best meets investigation is this scenario, since classroom teacher and students also participated in the content construction and strategies undertaken during the intervention. The study enrolled 28 students in the fifth grade, aging 10 to 11 years, in a Bauru/SP public school, physical education teacher and the researcher. Were planned and taught together, 14 classes over a semester with the handball and futsal content, guided for teaching tactics approaches. The data collections were made through systematic lessons observation (through filming and recording diary), interviews with students and descriptive reports made by the classroom teacher and researcher. The results indicate that there was an improvement in the phases of soccer and handball game, even though only the latter has changed its category phase to decentralized anarchic phase. Several students showed in the situational interviews, a more elaborate game understanding than the one identified in the game demonstration. In the analysis of relationship levels..

Orofacial/cerebral injuries and the use of mouthguards by professional athletes in Switzerland

The objective of the present study was to measure the occurrence of orofacial and cerebral injuries in different sports and to survey the awareness of athletes and officials concerning the use of mouthguards during sport activities. Two hundred and sixty-seven professional athletes and 63 officials participating in soccer, handball, basketball and ice hockey were interviewed. The frequency of orofacial and cerebral trauma during sport practice was recorded and the reason for using and not using mouthguards was assessed. A great difference in orofacial and cerebral injuries was found when comparing the different kinds of sports and comparing athletes with or without mouthguards. 45% of the players had suffered injuries when not wearing mouthguards. Most injuries were found in ice hockey, (59%), whereas only 24% of the soccer players suffered injuries when not wearing mouthguards. Sixty-eight percentage of the players wearing mouthguards had never suffered any orofacial and cerebral injuries. Two hundred and twenty-four athletes (84%) did not use a mouthguard despite general acceptance by 150 athletes (56%). Although the awareness of mouthguards among officials was very high (59%), only 25% of them would support the funding of mouthguards and 5% would enforce regulations. Athletes as well as coaches should be informed about the high risk of oral injuries when performing contact sports. Doctors and dentists need to recommend a more intensive education of students in sports medicine and sports dentistry, and to increase their willingness to become a team dentist.

Emotional contagion in team sports and its impact on individual performance – an experimental study

In sport psychology research about emotional contagion in sport teams has been scarce (Reicherts & Horn, 2008). Emotional contagion is a process leading to a specific emotional state in an individual caused by the perception of another individual’s emotional expression (Hatfield, Cacioppo & Rapson, 1994). Apitzsch (2009) described emotional contagion as one reason for collapsing sport teams. The present study examined the occurrence of emotional contagion in dyads during a basketball task and the impact of a socially induced emotional state on performance. An experiment with between-subjects design was conducted. Participants (N=81, ♀=38, M=21.33 years, SD=1.45) were randomly assigned to one of two experimental conditions, by joining a confederate to compose a same gender, ad hoc team. The team was instructed to perform a basketball task as quickly as possible. The between-factor of the experimental design was the confederate’s emotional expression (positive or negative valence). The within-factor was participants’ emotional state, measured pre- and post-experimentally using PANAS (Krohne, Egloff, Kohlmann & Tausch, 1996). The basketball task was video-taped and the number of frames participants needed to complete the task was used to determine the individual performance. The confederate’s emotional expression was appraised in a significantly different manner across both experimental conditions by participants and video raters (MC). Mixed between-within subjects ANOVAs were conducted to examine the impact of the two conditions on participants’ scores on the PANAS subscales across two time periods (pre- and post-experimental). No significant interaction effects but substantial main effects for time were found on both PANAS subscales. Both groups showed an increase in positive and a reduction in negative PANAS scores across these two time periods. Nevertheless, video raters assessment of the emotional states expressed by participants was significantly different between the positive (M=3.23, SD=0.45) and negative condition (M=2.39, SD=0.53; t=7.64, p<.001, eta squared=.43). An independent-samples t-test indicated no difference in performance between conditions. Furthermore, no significant correlation between the extent of positive or negative emotional contagion and the number of frames was observed. The basketball task lead to an improvement of the emotional state of participants, independently of the condition. Even though participants PANAS scores indicated a tendency to emotional contagion, it was not statistically significant. This could be explained by the low task duration of approximately three minutes. Moreover, the performance of participants was unaffected by the experimental condition or the extent of positive or negative emotional contagion. Apitzsch, E. (2009).

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
