Grounded Theory Based Research within Exercise Psychology: A Critical Review.

This article critically reviews the current body of grounded theory research within exercise psychology. Previous evidence has questioned the quality of grounded theory research within this academic domain. Guidelines for assessing grounded theory research are presented based on the common defining characteristics of the methodology and other published recommendations for assessing qualitative research. The review identified 21 articles that report on grounded theory studies conducted between 1999 and 2008. Findings comprise two sections: summary demographic characteristics and descriptive sample characteristics relating to the proposed assessment criteria. Results demonstrate that within exercise psychology, grounded theory is an increasingly popular methodological approach. However, many studies demonstrate a poor understanding of the grounded theory methodology or fail to present an adequate account of the research process. To further legitimise grounded theory as a form of enquiry within exercise psychology and to encourage greater research rigour in all grounded theory applications, it is crucial that both authors and reviewers understand the tenets of this approach and the limitations associated with a number of previous studies

Aspectos da ?drive for muscularity?em estudantes de Educação Física

“Drive for muscularity” refere-se ao desejo de alcançar um corpo musculoso idealizado e ao grau de preocupação que o sujeito pode ter a respeito do aumento da sua musculatura e a motivação para se tornar mais musculoso. O propósito deste estudo foi o de contribuir para a compreensão do “drive for muscularity” no cenário brasileiro, procurando identificar crenças, sentimentos e comportamentos a este constructo relacionados, em estudantes de educação física do sexo masculino. Dois grupos focais, com cinco participantes cada, foram realizados para evidenciar elementos de “drive for muscularity”. Através da análise de decomposição temática foram identificados dois temas, nos quais foram distribuídos cinco subtemas: “é importante ser musculoso”; “é importante ser suficientemente musculoso”; “construção do corpo musculoso”; “o peso de estar fora do padrão” e “o preço para atingir o padrão”. Concluiu-se que aparência e a função são importantes, aquele que parece forte também deve ser capaz de fazer força. O corpo suficientemente musculoso, com baixo percentual de gordura é aquele valorizado, inclusive no mercado de trabalho. A forma mais lícita de alcançar o corpo musculoso é através da rotina ascética de treinamento, alimentação balanceada e descanso. Os suplementos alimentares são recursos adicionais aceitos. O uso de esteroides anabolizantes por aqueles com “herança genética” desfavorável é inicialmente “perdoado”, mas o corpo que resulta deste recurso é fonte de sentimentos ambíguos

Mouse Models of Liver Fibrosis Mimic Human Liver Fibrosis of Different Etiologies

The liver has the amazing capacity to repair itself after injury; however, the same processes that are involved in liver regeneration after acute injury can cause serious consequences during chronic liver injury. In an effort to repair damage, activated hepatic stellate cells trigger a cascade of events that lead to deposition and accumulation of extracellular matrix components causing the progressive replacement of the liver parenchyma by scar tissue, thus resulting in fibrosis. Although fibrosis occurs as a result of many chronic liver diseases, the molecular mechanisms involved depend on the underlying etiology. Since studying liver fibrosis in human subjects is complicated by many factors, mouse models of liver fibrosis that mimic the human conditions fill this void. This review summarizes the general mouse models of liver fibrosis and mouse models that mimic specific human disease conditions that result in liver fibrosis. Additionally, recent progress that has been made in understanding the molecular mechanisms involved in the fibrogenic processes of each of the human disease conditions is highlighted
