RESUMO
A síndrome metabólica tem diversas similaridades com a síndrome de Cushing (intolerância à glicose, resistência à insulina, hipertensão, dislipidemia, obesidade central), sugerindo que anormalidades no metabolismo dos glicocorticóides estão associadas com a síndrome metabólica. Por outro lado, a prática regular de atividade física tem sido recomendada para a prevenção e a reabilitação de doenças cardiovasculares e outras doenças crônico-degenerativas. Estudos epidemiológicos têm demonstrado relação direta entre inatividade física e presença de múltiplos fatores de risco como os encontrados na síndrome metabólica. Os efeitos benéficos do exercício físico têm sido demonstrados na prevenção e no tratamento da hipertensão arterial, na resistência à insulina, no diabetes, na dislipidemia e na obesidade. Nesse contexto, esta revisão tem o intuito de discutir os efeitos metabólicos dos glicocorticóides e a associação da ação destes esteróides com as características da síndrome metabólica. Além disso, vamos explorar os mecanismos pelos quais a atividade física pode favorecer o metabolismo dos usuários de glicocorticóides.

ABSTRACT
Metabolic syndrome and glucocorticoid: Favorable aspects of physical exercise on this pathophysiology
The metabolic syndrome has several similarities with Cushing's syndrome (impaired glucose tolerance, insulin resistance, hypertension, dyslipidemia, central obesity) suggesting that abnormalities in the glucocorticoid metabolism have a link with the metabolic syndrome. On the other hand, regular physical activity provides several health benefits helping in prevention and rehabilitation of cardiovascular and other chronic diseases. Epidemiological studies have been demonstrating a direct relationship between physical inactivity and the multiple risk factors such as those found in the metabolic syndrome. Otherwise, it has been demonstrated the physical exercise benefit to prevent and treat arterial hypertension, insulin resistance, diabetes, dislipidemy, and obesity. This review will discuss the metabolic effects in the context of glucocorticoid metabolism and establish the association of glucocorticoid action with the features of the metabolic syndrome, specially obesity and insulin resistance. Moreover, we will explore how physical activity promotes favorable physiologic adaptations improving quality of life in the abnormalities metabolic association with the excess of glucocorticoid.
Keys Words: glucocorticoid, metabolic syndrome and physical exercise.
