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.

O conhecimento did��tico do conte��do e a qualidade do ensino : um estudo na disciplina de Qu��mica com a 7�� classe do sistema educativo angolano

Com o intuito de contribuir para a qualifica����o do ensino escolar da Qu��mica na Rep��blica de Angola, a presente investiga����o analisou as carater��sticas do Conhecimento Did��tico do Conte��do e a Qualidade de Ensino dos professores considerados peritos naquela ��rea disciplinar. A quest��o de partida que orientou o estudo foi a seguinte: ���O que �� que carateriza o Conhecimento Did��tico do Conte��do dos professores peritos de Qu��mica e qual a sua rela����o com a Qualidade de Ensino?���. A investiga����o implementada �� de tipo quasi-experimental, com um car��ter descritivo e explorat��rio. A amostra foi constitu��da por grupos de professores e alunos (peritos e n��o peritos). Os dados recolheram-se por entrevistas aos professores peritos e a observa����o das suas aulas, por capta����o de imagens; por question��rios e testes de avaliação aos alunos dos dois grupos. A an��lise dos resultados obedeceu a metodologia quantitativa e qualitativa. Os resultados revelam que, os professores peritos re��nem requisitos caraterizados pelas suas interven����es de pedagogias mais ativas que os tornam mais eficazes. As carater��sticas das suas interven����es propiciam melhorias na qualidade de ensino. Contudo, as conclus��es gerais implicam a necessidade de forma����o dos professores, de modo a melhorar a qualidade de ensino da Qu��mica em Angola.
