Este texto relata alguns dos resultados de nossa pesquisa que teve como objeto de estudo central a análise dos processos de iniciação à docência de licenciados em Educação Física (EF). O estudo tem como objetivos identificar quais as percepções que professores de Educação Física iniciantes têm deste ciclo de desenvolvimento profissional; analisar como professores de Educação Física iniciantes pensam e atuam profissionalmente de forma a integra-se às situações de trabalho; entender como os professores iniciantes aprendem a ensinar nos primeiros anos de exercício profissional na escola. A pesquisa lançou mão dos seguintes instrumentos de coleta de dados: realização de entrevistas com docentes iniciantes e análise de casos de ensino confeccionados por meio de relatos escritos. Nosso estudo aponta para o caráter situado da iniciação à docência no qual se podem verificar singularidades de experiências e percepções sobre esse ciclo de desenvolvimento profissional. Esse caráter contextual da inserção profissional mostrou-se fortemente relacionado ao campo disciplinar (EF) a qual os professores pertencem.

IntroductionDespite its frequent occurrence, external-traction headache (previously named as “ponytail headache”) is scarcely documented in the literature.ObjectiveIn the present study we set out to estimate the prevalence of ponytail headache and its relationship with migraine.MethodsOne hundred and thirty women (27.7±11.1 years of age), 108 of them reported a previous history of primary headache [81/130 (62.3%) migraine or probable migraine and 27/130 (20.8%) non-migraine headache; 22/130 (16.9%) did not report any previous episode of headache], were requested to wear a ponytail for 60 minutes, removing it only in case of pain. When pain occurred, it was recorded for the latency between the placement of the ponytail and the onset of the pain, its duration and characteristics. The women also filled out a questionnaire on previous headache episodes.ResultsDuring the 60 minute-period, 52/130 (40%) women had ponytail headache elicited by the experiment. There was a higher prevalence of ponytail headache in those who reported previous episodes of primary headache [48/108 (44.4%)], compared to those who did not [4/22 (18.2%)] (p=0.022). The migraineurs had more ponytail headache than non-migraneurs [39/81 (48.2%) versus 9/27 (33.3%), p=0.180] with a positive history of primary headache and they also had more than those without [4/22 (18.2%)] (p=0.012). The group of women with migraine also presented more ponytail-induced headache than non-migraineurs combined with the groupof individuals without a previous history of headache [13/49 (26.5%), OR 2.57, 95%CI 1.19-5.55; p=0.015]. Migraine-like episodes were trigged in 3/52 (5.8%) by the experiment, all three migraineurs. The latency time for the beginning of ponytail headache during the experiment was 21.5 ± 15.4 min and the duration was 76.0±159.3 min.ConclusionThe prevalence of ponytail headache in our study was 40% and was statistically higher in migraineurs.
