Physiological responses in futsal have not been studied together with temporal information about the players’ stay on the court. The aim of this study was to compare heart rate (HR) and blood lactate concentration ([La−]) responses between 1-H and 2-H considering the time of permanency of the players on the court at each substitution in a futsal match. HR was recorded during entire match and [La−] was analyzed after each substitution of seven players. %HRmean (89.61 ± 2.31 vs. 88.03 ± 4.98 %HRmax) and [La−] mean (8.46 ± 3.01 vs. 8.17 ± 2.91 mmol·L−1) did not differ between 1-H and 2-H (ES, trivial-small). Time in intensity zones of 50–100 %HRmax differed only in 60–70 %HRmax (ES, moderate). HR coefficient of variation throughout the match was low (7%) and among the four outfield players on the court (quartets, 5%). Substitutions (2 player’s participation in each half), time of permanence on the court (7.15 ± 2.39 vs. 9.49 ± 3.80 min), ratio between time in- and out-ratio on the court (In:Outcourt = 1:1.30 ± 1:0.48 vs. 1:1.05 ± 1:0.55 min) also were similar between 1-H and 2-H (ES, moderate and small, respectively). Balancing the number of substitutions, and the In:Outcourt ratio of players in both halves of the match, playing lower time at 1-H, ~8 min for each participation in the match, made it possible to maintain intensity of the match in 2-H similar to the 1H. These results are a good guidance to coaches and for application in future studies.

Este artículo analiza el constructo de autoeficacia, configurado como el conjunto de creencias sobre la capacidad para ejecutar planes de acción, en la práctica docente, en sujetos participantes de una investigación psicométrica realizada con educadores chilenos de la región del Ñuble y su relación con aspectos de formación y educación desempeño profesional, considerando variables sociodemográficas. Es un estudio transversal con alcance descriptivo y comparativo. Participaron 193 docentes de Educación Física de la Región de Ñuble con edad 33,9±8,9 años (mínimo=25 años y máximo=66 años). 65 de ellos son mujeres y 128 hombres. En el estudio no hubo diferencia significativa en la percepción de autoeficacia entre géneros; Hubo una mayor percepción de autoeficacia en el manejo del aula en docentes con más de 25 años de experiencia en comparación con docentes con hasta 7 años de experiencia. En cuanto al nivel de formación, los docentes de posgrado mostraron mayor autoeficacia en comparación con los docentes que solo se graduaron en la dimensión de estrategias de enseñanza y aprendizaje de las escalas. Hubo una diferencia entre los docentes que trabajaban en el sistema escolar público que mostraron una mayor autoeficacia en las estrategias de enseñanza y aprendizaje, en comparación con los docentes que trabajaban en el sistema escolar privado.

-Aims:The behavior of laboratory animals has been studied through displacement, with different objectives by researchers. Methods: Although different methods have already been used in the tracking of laboratory animals, manual tracking mode videogrammetry for 2D analysis of displacement has not been observed in animal studies. The aim of this study was to verify the accuracy and reliability of determining the displacement of Wistar rats by means of videogrammetry software Dvideo. The accuracy (between the known distance and distance traced) was determined by 3 different evaluators twice consecutive, by videoing a course of 10 meters in the enriched environment together with further analysis of the displacement of the midpoint marked on an apparatus. To calculate reliability (accuracy of the measurement system) and reproducibility (precision of the evaluators) to obtain the ratio of precision to tolerance (P/T), eight animals were filmed for 10 minutes in the enriched environment and analysis of distance covered by one of the animals by three different reviewers thrice consecutive. Results: The results obtained in the course of 10 meters of the known distance demonstrated accuracy of 0.10 m, precision of 0.05 m, and bias of 0.07 m. In the reliability test during the 10 minutes of displacement (m) of animal, the ratio of precision to tolerance (P/T) = 0.1 m was found between three different evaluators, demonstrating adequate capacity of the measure. Conclusion: The manual tracking mode of the Dvideo presented high reliability and it can be employed for the displacement analysis of studies with rat experimental models.

Introdução: Estudos mostram que o uso crônico de substâncias psicoativas está associado com redução na função cognitiva, além de afetar de forma negativa a regulação emocional reforçando o comportamento para o uso de drogas. Objetivo: analisar o efeito agudo de uma partida de futsal sobre o estado de humor e na função cognitiva em indivíduos toxicodependentes, atendidos no CAPS-ad. Métodos: Os participantes foram divididos em dois grupos, Grupo controle (n = 10) e Grupo futsal (n = 10). Para a avaliação do estado de humor foi utilizado à escala de humor de Brunel e o teste de cubos de Corsi para a memória de trabalho visuespacial. Resultados: Na análise intergrupos pós-intervenção, verificou-se redução dos fatores raiva (p = 0,008), depressão (p = 0,005) e tensão (p = 0,009). Já na análise intragrupos, o grupo futsal apresentou redução dos fatores raiva (p = 0,03), depressão (p = 0,007) e tensão (p = 0,01) evidenciando mudança no estado de humor. Em relação à memória operacional, houve um aumento na quantidade de blocos recordados (p = 0,0002) na análise intergrupos e intragrupo (p = 0,01) no grupo futsal. Conclusão: A realização de uma partida de futsal utilizada como uma estratégia não farmacológica no tratamento de dependentes químicos foi capaz de modular de forma positiva o estado de humor e a função cognitiva destes sujeitos. No entanto, o jogo de futsal ainda precisa ser mais estudado como opção de conteúdo em um programa de atividade física regular para o tratamento de dependentes químicos.
