INTRODUÇÃO: O Running Anaerobic Sprint Test (RAST) tem sido considerado um teste válido para avaliação anaeróbia. Entretanto, como a superfície e o calçado podem afetar alguns parâmetros mensurados durante o exercício, isso pode modificar os parâmetros do RAST. OBJETIVO: Comparar as variáveis do RAST mensuradas utilizando chuteiras na grama (RAST CG) e tênis na pista (RAST TP). MÉTODOS: Oito jogadores de futebol (da categoria sub-17) participaram do estudo. Os participantes realizaram dois RAST (intervalo > 24 h). O RAST consistiu em seis corridas máximas de 35m com 10s de intervalo passivo entre cada corrida. O tempo de cada esforço foi registrado para determinação da potência pico (PP), potência média (PM) e índice de fadiga (IF). Após o sexto esforço, amostras sanguíneas foram coletadas para determinação da lactacidemia ([Lac]). RESULTADOS: Durante o RAST TP, a PP (763,1 ± 87,2 W) e PM (621,6 ± 68,1 W) foram significativamente superiores às PP e PM mensuradas em RAST CG (PP = 667,3 ± 67,0 W e PM = 555,9 ± 74,7 W), enquanto que as [Lac] observadas em RAST TP (7,3 ± 1,8 mmol.L-1) foram significativamente inferiores às mensuradas em RAST CG (9,9 ± 3,2 mmol.L-1). No entanto, o IF não foi significativamente diferente (RAST TP = 32,5 ± 8,3%; RAST CG = 34,1 ± 6,6%). Significativas correlações foram observadas entre as PM (r = 0,90) e as [Lac] (r = 0,72). CONCLUSÃO: Podemos concluir que as variáveis do RAST são influenciadas pela superfície e calçado utilizados, com valores superiores observados em RAST TP.

O objetivo do presente estudo foi avaliar os efeitos do treinamento no período preparatório em atletas profissionais de futebol. Participam 17 atletas, com idade acima de 18 anos que disputaram a terceira divisão do campeonato paulista, em 2009. O programa de treinamento predominante foi o tipo neuromuscular e por meio dos testes de sentar e alcançar, salto sêxtuplo, salto vertical e velocidade de deslocamento em 30m os atletas foram avaliados antes do início do programa de treinamento (M1) e após sete semanas (M2). Os dados coletados foram armazenados em banco computacional, produzindo-se informações no plano descritivo (medidas de centralidade e dispersão) e, no inferencial, Teste t de Student e Anova One-way. Os principais resultados apontam para melhora da flexibilidade, força explosiva e rápida, e sensível diminuição na velocidade de deslocamento em 30 metros.

A partir de um acidente causado pela picada de uma formiga falsa tocandira na mão de um pescador amador, os autores descrevem os achados clínicos locais observados, tais como edema, eritema e dor excruciante e a evolução do envenenamento, que cursou com fenômenos sistêmicos imediatos, como sudorese fria, náuseas, vômitos, mal estar, taquicardia e linfadenopatia axilar à esquerda. Após três horas, a dor intensa persistia e o paciente apresentou um episódio de hematoquesia, sem história anterior de enfermidades do trato digestivo, hematológicas ou vasculares. O uso de analgésicos (Tramal® 300 mg/dia), água quente e gelo não melhorou a dor, que arrefeceu em oito horas, tendo permanecido por cerca de 24 horas. São apresentados ainda os aspectos folclóricos, farmacológicos e clínicos relacionados às picadas de tocandiras.

One of the most important characteristics of intelligent activity is the ability to change behaviour according to many forms of feedback. Through learning an agent can interact with its environment to improve its performance over time. However, most of the techniques known that involves learning are time expensive, i.e., once the agent is supposed to learn over time by experimentation, the task has to be executed many times. Hence, high fidelity simulators can save a lot of time. In this context, this paper describes the framework designed to allow a team of real RoboNova-I humanoids robots to be simulated under USARSim environment. Details about the complete process of modeling and programming the robot are given, as well as the learning methodology proposed to improve robot's performance. Due to the use of a high fidelity model, the learning algorithms can be widely explored in simulation before adapted to real robots. © 2008 Springer-Verlag Berlin Heidelberg.

The aim of this study was to evaluate the effect of warm up performed by dynamic exercises (DYN) and small sided soccer game (SOC) on agility with ball (AB) and agility without ball (AG). Eighteen children of both genders (n=18) performed the AB and AG tests after three conditions: without warm-up (WWU), DYN and SOC. The effects of DYN and SOC warm-ups on AG test was higher than WWU (p<0,05) and it was similar among them (WWU=12,2 ± 1,0, DYN= 11,3 ± 0,7, SOC=11,4 ± 0,6 s), as well as on AB test (WWU=15,0 ± 2,1, DYN= 14,4 ± 2,1, SOC=14,0 ± 1,6 s). Results in both tests were similar by gender, except in AB test performed with DYN warm-up, in girls. SOC is an effective warm-up protocol for agility tests with or without ball and can be used before agility motor tasks in children.

This article aims to understand how the participation and performance of the state of Bahia at the I Campeonato Brasileiro de Seleções (I Brazilian Soccer Championship), also known as the Torneio do Centenário (Centenary Championship) in 1922 represented an opportunity for the state to claim a centrality in the formation of a national identity associated with soccer. The tournament was conceived as a draft for the formation of a national soccer team that would participate in the VI Campeonato Sul Americano (VI South American Championship) in Brazil. In addition, the event also came to be regarded as a celebration of the fi rst centenary of the Independence, a date that has encouraged the country to refl ect upon its national identity, as well as to reconsider its insertion in modernity. Bahia did well in the tournament, ensuring the second position. As a result, the local press went on to claim the participation of their athletes in the national team and to criticize the disregard of the states of Rio de Janeiro and São Paulo towards the Northern region of the country. The local press would also challenge the policies of the Confederação Brasileira de Desportos (Brazilian Sports Confederation), the CBD, claiming that they favored the Southern states. Moreover, for the local elites the success of Bahia in the tournament represented the strength and greatness of the state, which gave them the right to claim a greater space and role in the destiny of the country. Finally, the performance of Bahia and its consequences have allowed us to question the limits and peculiarities of the formation of a national identity through the sport, at a moment when the country sought to rethink their identity historically marked by disputes and regional tensions.

The present article is set to analyze the career of a soccer coach, highlighting information that may be assist in the discussion on graduating and professional actuation in Physical Education and Sports. The research, qualitative, used Life History as a method of data collection. To elucidate and articulate issues raised was used concepts from sociological theory of Norbert Elias. From the explicit path and the proposed configuration of Elias, we conclude that the figure of the trainer was formed as a result of interdependence established within the specific groups which took part, enriched by the academic.

The objective of the present study was to analyze the most appropriate water depth for maintaining a good quality of Bermudas Grass (Cynodon dactylon) for soccer fields while saving water and electrical resources. Four treatments were used: T1 - irrigated with a water depth of 50% of evapotranspiration (ETo), T2 - irrigated with a water depth of 75% of ETo, T3 - irrigated with a water depth of 100% of ETo and T4 - irrigated with a water depth of 150% of ETo, all treatments were irrigated daily. The reference ETo was obtained by the Penman-Monteith method. The study was conducted in an experimental area of the Instituto Federal de Educação, Ciência e Tecnologia do Triângulo Mineiro - Campus Uberaba, Uberaba, Minas Gerais, Brazil, from June to September 2010 and from January to March 2011. Three evaluations of the variables were performed during the experimental period. The samples were obtained with the help of a cylindrical extractor with 10 cm in diameter and 30 cm in height. In each sample height and dry organic matter (leaf, root and organic material) were analyzed. The experimental design was randomized block with four treatments in five blocks. No significant differences were observed for dry matter and height (roots and organic material). The best results were those for T4 which obtained the greatest height.
