Inclusão da aptidão física no contexto escolar : um estudo centrado na perceção do professor

O presente relatório teve por objetivo analisar o estudo realizado no âmbito da atividade de Investigação e Inovação – Área 2 do Estágio Pedagógico realizado na Escola Secundária Augusto Cabrita no ano letivo 2003/ 2004. O estudo teve como objetivo aferir a perceção dos professores, relativamente à inclusão da aptidão física no conjunto de matérias a abordar na disciplina de Educação Física, conforme proposto pelos Programas Nacionais da disciplina. Foram analisadas 3 dimensões: perceção, treino/ aplicação e avaliação/ classificação, tendo sido verificada quais as associações existentes entre estas variáveis. Para o efeito foi elaborado um questionário, que foi preenchido por 168 professores de Educação Física das escolas básicas e secundárias do ensino público, do Centro de Área Educativa da Península de Setúbal. Os resultados do estudo revelaram que os professores tinham uma perceção positiva sobre a aptidão física reportada à saúde. Esta perceção influencia a adoção de processos de treino e o número de horas dedicado para o efeito durante as aulas de Educação Física, não influenciando, porém, a adoção de processos de avaliação. Verificou-se também, que existia uma associação entre a adoção de processos de treino e a adoção de processos de avaliação.

Effects of a resistance and stretching training program on forward head and protracted shoulder posture in physical education classes in students aged 15-17 years old

Purpose: This study aimed to characterize the postural alignment of the head and shoulder in the sagittal plane of Portuguese adolescents, 15-17 years old, and to evaluate the effects of a 32-week resistance and stretching training program applied in Physical Education classes on forward head posture and protracted shoulder posture of Portuguese adolescents. After 32-training weeks the detraining effects after a 16-week period were measured. Methods: This randomized and controlled study was conducted in two secondary schools in Portugal for 48 weeks. Prior the study 275 students aged 15-17 years old were evaluated. Sagittal head, cervical and shoulder angle were measured with photogrammetry and Postural Analysis Software. After this assessment 130 adolescents were considered to have forward head and protracted shoulder posture and were randomly assigned to a control group, an experimental group one or experimental group two. The control group (n=46) only did the Physical Education classes whereas the intervention group one (n=42) and two (n=42) performed a 16-week and 32-week stretching and strengthening program in addition to Physical Education classes, respectively. The postural angles were measured before and after the 16-week and 32-week time intervention period for the three groups and after a 16-week detraining period following the 32-week in intervention group two. Results: 68% of the adolescents studied revealed anteriorization of the head whereas 58% of them had protraction of the shoulder. Significant increases were observed in the cervical and shoulder angle in the experimental group (n=84) following the 16-week and in experimental group two (n=42)after the 32 week-intervention period. After the 16-week detraining period no significant differences were observed in the three postural angles in the intervention group two. Conclusions: Forward head and protracted shoulder are common postural disorders in Portuguese adolescents. The exercise intervention was successful ate decreasing forward head and protracted shoulder in adolescents. Detraining period of 16-week didn´t reduce the overall training effects.
