Resumo. O objetivo do estudo foi caracterizar as aulas de educação física (EF) em duas escolas secundárias com metodologias de trabalho distintas. Foram avaliadas 37 aulas de EF através do System for Observing Instruction Time e calculadas as proporções médias do tempo de aula de cada comportamento do professor, do aluno, das situações do contexto da aula e o nível de atividade física (AF) proporcionado. As comparações entre escolas foram efetuadas por meio do teste T-Student. Nas duas escolas os alunos passaram muito tempo em atividades sedentárias e uma menor proporção de tempo em atividade física moderada a vigorosa, 40,1% e 38,8% para a escola A e B, respectivamente. O contexto predominante na escola A foi de atividades para aptidão física (37.2%), apresentando diferenças significativas (p<.05) em relação à escola B (2%). Na escola B predominaram os jogos estruturados (62.5%). Os professores da escola A dedicaram mais tempo às instruções gerais (41.1%), enquanto os professores da escola B ficaram mais tempo em observação (42.2%). As metodologias distintas desenvolvidas pelas escolas proporcionaram aulas de EF com reduzidas proporções de AF em níveis adequados para obtenção de benefícios à saúde.Resumen.

This study aimed at characterizing physical education (PE) classes in two secondary schools with different working methods. One school (A) was more sport oriented, and the other implement traditional PE classes. Thirty-seven PE classes were assessed through the System for Observing Instruction Time and the average proportions of class time for each teacher and student behavior, class context, and levels of physical activity provided were calculated. Comparisons between schools were made using the Student T-test. In both schools students spent much time in sedentary activities and a smaller proportion of time in moderate to vigorous physical activity, 40.1% and 38.8% for school A and B, respectively. In school A, teachers devoted more time to physical fitness activities (37.2%), presenting significant differences (p <.05) compared to school B (2%). In school B, structured games were predominant (62.5%). School A teachers spent more time on general instructions (41.1%), while in school B teachers spent more time on observations (42.2%). The different methodologies developed by the two schools provided PE classes with reduced physical activity proportions at adequate levels for obtaining health benefits.

This study analyzed the relationships hypothesized by the Theory of Achievement Objectives in physical education classes and school satisfaction in the prediction of attitudes (the taste for physical activity and self-efficacy) and the level of physical activity of adolescents from two secondary schools. 624 adolescents (326 boys) participated, aged between 14 and 17 years old from two schools in Fortaleza, Ceará, Brazil. Several questionnaires were used as an instrument. Linear regression analysis stratified by school was performed, testing three models hierarchically. Most students did not meet the recommendations for physical activity (<60 min / day) and showed moderate effectiveness, with no significant difference between schools. There was a difference between schools regarding the taste for physical activity (p = 0.001), school satisfaction (p = 0.007), the mastery objective (p <.001), the social approval objective (p = 0.002), the mastery climate (p <0.001) and the performance-approximation climate (0.001). In conclusion, the model that included the motivational climate, school satisfaction and achievement objectives, proved to be the most adequate to predict the physical activity of students from both schools.
