Resumo O presente artigo analisa os aspectos que influenciam a performance do jogador de futebol e os fatores contextuais relacionados. Com esse objetivo, fez-se um estudo entrevistando 2 ex-atletas, 2 jogadores que ainda atuam, 2 treinadores e 2 preparadores físicos-todos experientes e consagrados em suas profissões-para verificar quais são os fatores considerados importantes para a performance dos jogadores de futebol. Realizou-se análise de conteúdo sobre os dados das entrevistas. Constatou-se que muitos fatores envolvem o contexto que influencia o desempenho. Esses podem ser divididos em fatores psicológicos, físicos, técnicos e táticos e de suporte social oferecido ao jogador. A partir das categorias levantadas, estabeleceram-se as bases para construção de um questionário contendo os principais temas abordados pelos entrevistados, o qual será utilizado num estudo posterior.
We assess the effects of a Brazilian extended high school day program on college admission test scores. The program entails an increase in Math/Science and Language class time, and the introduction of extra-class activity time. We exploit variation in program implementation timing to apply a difference-in-differences strategy and an event-study approach. Results show positive large effects on test scores and suggest that these effects are likely driven by increased class and extra-class activity hours. Moreover, the program affects not only scores in subjects for which it contemplates increased class time, but also in Humanities. Finally, we are able to show that increased time dedicated to academic-related extra-class activities works as a multiplier of program effects. In fact, these additional hours spent in complementary activities make the magnitude of program effects double from 0.092-0.150 to 0.180-0.317 standard deviation.
