Soccer is one of the most practiced sports in the world, and for many years, some areas of physical education has been doing studies related to the improvement of their income from these areas if this sport psychology. The psychological aspects are very influential and involved in the daily life of an athlete, especially for basic categories of athletes who see in soccer a dream to come true or only a source of income for his family, where such aspects act beneficially or evil for the athlete. Stress, in particular, can appear in various situations and in various ways, and different influences and reactions athlete to athlete, also resulting in physiological changes and variations in performance. Stress, and especially stressful situations, like any psychological aspect should be identified in order to train your athlete to know how to deal with stressful situations. Know what are the stressors, which carries the stress load for the athlete, how to handle the stressful situations, using psychological training in the preseason, know how to use stress management techniques, and be able to manage it all so your athlete reaches an optimal level of income is described in the present work, in order to provide a theoretical and updated reference for professionals of Physical Education, so that they stay up to date on sports psychology and also understand a little more on this subject, which is still little discussed within soccer and often overlooked by many professionals who are already in the context of competitive soccer

Lateral asymmetries are in everywhere as well as in all movements made by man, which become more evident in movements of sport. The asymmetry is particularly pointed out in futsal when players, even with clear opportunity of making use of their non-preferred foot, try to place the ball in order to execute the action with their preferred foot. The study of asymmetry in futsal is quite relevant, once ambidextrous players present advantages in their performances during a match, which can help futsal athletes not only in their performance improvement but also with the prescription of training. For this reason, the present study had questioned: is there symmetry/asymmetry at the performance of lower contralateral limbs during actions with the possession ball (pass, receiving a ball and kick into the goal) during a futsal match? Thus, the aim of this study was to analyze the symmetry/asymmetry using the preferred and non-preferred foot in actions with the possession ball (pass, receiving and shoot) in adult Futsal's players (professional). The winner team of eight matches of the 2012 FIFA Futsal World Cup was analyzed. An average of 75 players had all their actions (pass, receiving a ball and shot on goal) using their lower limbs during the match analyzed. However, their actions with the head and torso were not analyzed. The games were acquired through a television broadcast. All eight matches were followed by an appraiser through a computer. The Skout® software was used to collect the data, taking notes of the player involved, the type of action (pass, receiving a ball and shot on goal), its foot used (preferred or non-preferred foot) and if the execution was correct or wrong. These data were saved in a text file, in the form of a matrix and imported into the Matlab® software, where was analyzed the following parameters: frequency of occurrence of each action with each foot and quantity of correct and wrong occurrences performed with...

The aim of this study was to verify the effect of selective loads model in professional futsal players, during a preparatory mesocycle. Nine futsal professional players (23±2 anos), from the team of Federation Paulista of soccer indoor championship, composed the sample, characterized by intentional. The players were evaluated in two moments although of a preparatory mesocycle, microcycle 2 (PRE) and microcycle 7 (POS), by the tests of intermittent aerobic fitness, horizontal jump, one leg triple jump, velocity of 15m, agility and anaerobic power. The statistical analysis included the Student-t and Wilxocon tests (P<0.05). The results of horizontal jump, intermittent aerobic fitness and medium power improved, the velocity at 15 m decreased. The select loads model is a good option for the periodization to preparatory mesocycle in futsal.

Studies on stress in the sport are broad and profound. However, we do not found approach to study the perceptions of trainers on the subject and how it influences the organization of training throughout the season. From this premise, the aim of this work is to verify that the perception of the trainer about stress and its influence on planning. To this end, we chose a qualitative research, through an open interview, carried out with a trainer for a professional soccer team as a pilot for future studies. The interview responses are consistent with the findings of the literature on the changes in the players arising from the interference of stress in the various dimensions. But it was also possible to identify the trainer interviewed pointed out that stress, especially during the competition changes the preliminary planning, therefore, modify the activities to be applied to players depending on the outcome of matches. This pilot study we subsidized the development of new questions that will be inserted in the continuity of the study

Introdução: O futsal é uma modalidade esportiva altamente dinâmica e sua prática em nível de rendimento é caracterizada por uma exigência altíssima dos sistemas anaeróbio e aeróbio, sendo o último, responsável por sustentar as altas intensidades exigidas durante a partida. Um exemplo de teste para avaliar a capacidade aeróbia é o “Circuito de Hoff”, porém específico para o futebol. Com a finalidade de elaborar um protocolo de teste específico para o futsal, este estudo procura padronizar o teste “Circuito de Hoff” como uma forma i ndireta de i nvestigar a capacidade aeróbia de atletas dessa modalidade. Objetivo: Padroni zar o “Circuito de Hoff” para avaliação da capacidade aeróbia de jogadores de futsal, determinada pelo teste de lactato mínimo. Metodologia: Participaram do estudo 8 atletas de futsal do sexo masculino (idade: 21,75±2,05 anos) pertencentes a uma equipe universitária de competição do Estado de São Paulo. Inicialmente os participantes passaram por uma avaliação antropométrica e deram início ao um período de 5 dias de familiarização ao Hofffutsal e logo após então realizaram o teste de lactato mínimo no circuito Hofffutsal. Após 7 dias, teste de lactato mínimo no circuito Hofffutsal foi reaplicado para a verificação da reprodutibilidade (intra-teste). Para análise estatística de normalidade e homogeneidade dos dados foram utilizados os testes Shapiro-Wilks e Levene respectivamente. Para comparação dos resultados foi realizado o teste t de Student pareado e a correlação de Pearson (p<0,05). Resultados: O teste t de Student não encontrou diferenças estatísticas entre os valores de Lac_mín teste x Lac_min Re-teste, e R2 Teste X R2 Re-teste. Apresentou-se valores de 7,75±0,29 mmol/l de lactato mínimo e r2 de 0,94±0,09 para teste e um valor de 7,69±0,29 mmol/l de lactato mínimo ...(Resumo completo, clicar acesso eletrônico abaixo)

O futsal é uma modalidade intermitente cuja a participação do metabolismo aeróbio é importante na ressíntese de ATP e CP gastos anaerobiamente. A capacidade aeróbia máxima (VO2max) pode ser mensurada por testes de campo e testes laboratoriais. Dentre os vários testes laboratoriais existentes, se destaca o teste de Ellestad, devido à sua segurança e capacidade diagnóstica de patologias cardíacas. Dentre os testes de campo se destaca o teste de Vai e Vem de 20m (VV20m), devido à sua alta validade e reprodutibilidade em adultos, e devido à alta especificidade ao futsal e ao futebol, comprovado pela existênicia de correlações significativas do desempenho no VV20m com várias medidas de performance no futebol. Porém, não existem estudos sobre a validação ou concordância do teste de Ellestad em atletas de esportes coletivos. Portanto, o objetivo do presente estudo foi testar a concordância do teste de Ellestad e o VV20m na predição do VO2max em atletas de futsal. Quinze jogadores semi-profissionais (25,4 ± 5,51 anos, 70,37 ± 5,74kg, 1,75 ± 0,04m e 8,43 ± 3,02% de gordura) realizaram os testes de Ellestad e o VV20m em ordens aleatórias, separados por quatro dias. A concordância foi testada pela comparação entre as diferenças (Teste t-studet para dados independentes), correlação (coeficiente de Pearson) e concordância (dipersão de Bland e Altman). Não houve diferença significativa entre os valores de VO2max estimados pelos dois protocolos, mas a correlação foi significativa (p < 0,05; r = 0,479; EPE: 1,8 mlO2×kg -1 ×min -1 ) entre os métodos. A análise de Bland e Altman apresentou concordância entre os testes para um intervalo de ±95% em torno da média da diferença (1,3 mlO2×kg -1 ×min -1 ), porém a dispersão indica um enviesamento positivo e significativo (p < 0,01), sugerindo que a a diferença aumenta com o aumento da média do VO2max. Assim, para atletas de alto rendimento, o teste de Ellestad não apresenta a mesma adequação na determinação do VO2max, quando comparado ao VV20m.

The soccer is a sport that can be decided in a penalty, including world champions have already been defined For this, shoot a penalty or defend a penalty can build heroes and villains in this sport so popular and competitive. Studying penalty kicks will a better understanding of the actions of goalkeepers and kickers. This study looked at 527 penalty charges in professional games in 2010 to 2015. The objective was to verify the fact that the charge be right-handed or left-handed interfered with the action of the goalkeeper, differences in efficiency of left-and right-handed players, check results in penalty situations in the match and in the disputes of penalties and performance of players in club games and selections. The complete use in 527 penalty charges was 74%. It is concluded that if the debt collector is right-handed, the goalie moves to the right and if it's left-handed move more to the left. Tax collectors selections had better use (77%) than the clubs. Right-handers presented more efficacy (76%) compared to lefties (66%). The index of the goalkeepers was greater when centered (22%), although 91% of all charges being directed to the right and left sectors
Fatores de risco para síndrome metabólica em cadeirantes: jogadores de basquetebol e não praticantes
Resumo:
A atividade física tem sido sistematicamente estudada como fator preventivo no acometimento de enfermidades crônico-degenerativas, especialmente a síndrome metabólica e doenças cardiovasculares. Sedentarismo está relacionado à diminuição ou ausência de parâmetros mínimos de exigência física diária além do estado de repouso, sendo este fortemente associado à redução na condição de saúde dos indivíduos portadores de deficiência física. As respostas metabólicas do organismo mediante a ausência de determinada musculatura, ou sua inatividade pela falta de estímulos, conduzem a diferenças significativas na estruturação da composição corporal. Esta pesquisa teve como objeto o exercício físico regular e a condição de saúde de indivíduos portadores de deficiência física, através da determinação do perfil antropométrico e bioquímico sangüíneo, e ainda pela determinação da prevalência de fatores de risco para síndrome metabólica. Foram estudados 27 homens com paraplegia (T2-L1), portadores de seqüelas de poliomielite ou amputados, divididos em jogadores de basquetebol cadeirantes (JBC) e não jogadores de basquetebol cadeirantes (NJBC). Os JBC apresentaram circunferência de cintura menor comparada aos NJBC, 76,40±8,44 e 89,25±9,73 cm respectivamente (p<0,05). A pressão arterial sistólica foi significativamente maior nos NJBC 123,33±13,70 e 114,00±9,85 mmHg para JBC (p<0,05), não sendo verificada diferença para PAD. Os NJBC apresentaram valores superiores aos JBC para a bioquímica sangüínea de glicemia, TG, CT e frações, exceto para HDL-C (p<0,05). Os indivíduos NJBC apresentaram alta prevalência para fatores de risco da SM, sendo hipertensão arterial prevalente em 58,33% dos indivíduos, dislipidemia de HDL-C presente em 50% e circunferência de cintura acima da normalidade em 41,66%. Os achados do presente estudo sugerem um papel importante do exercício físico na prevenção da síndrome metabólica, embora estudos adicionais devam ser realizados para a melhor compreensão dos mecanismos que promovem a saúde dos deficientes físicos ativos.

Since the sport of football field as the main focus and it is directly related to sports phenomenon up to understood of changes occurring in the rules and game systems over the years. The main aim was analyzed the historical changes in the soccer with relation to the game systems and rules, and their consequences. The research is qualitative type and uses the bibliographic collection as instrument. For this, it was searched in the published literature data about the present study subject. The results indicated for a soccer tactics and rules set that it was constructed with the evolution and consolidation of the soccer. It was concluded that the game system had suffered many alterations during the historical process of soccer development, but this process leaved poured the spectacle of the game. In the other way, the rules had suffered great alterations with regard to the soccer primaries, but after its consolidation as universal sport, they had remained almost the same, having assisted in the maintenance of the soccer characteristics and status.
