Resumo
Em Portugal 0,6% dos adultos são obesos mórbidos. Como a cirurgia bariátrica tem vindo a ganhar popularidade no tratamento desta população, o objectivo principal do presente trabalho é analisar a associação entre a perda de peso e os hábitos de actividade física em adultos obesos mórbidos submetidos a cirurgia bariátrica. Como objectivo secundário estudámos a associação entre os hábitos de actividade física actuais e a maximização da perda de peso, bem como, a sua associação à capacidade aeróbia, nesta população. Este trabalho divide-se em duas partes fundamentais, a primeira uma revisão sistemática da literatura que sumarizou os efeitos da actividade física e/ou exercício físico após cirurgia bariátrica como parte de uma abordagem multidisciplinar. Este estudo permitiu constatar impactos benéficos sobre variáveis antropométricas e da composição corporal, níveis de actividade física/exercício físico, aptidão física, aptidão física funcional, qualidade de vida e marcadores bioquímicos após cirurgia bariátrica. A segunda parte, um estudo experimental onde participaram 75 obesos mórbidos submetidos a cirurgia bariátrica com idades compreendidas entre os 18 e os 65 anos. Os sujeitos responderam a um questionário sobre hábitos de actividade física, que analisou os hábitos de actividade física e a sua associação à aptidão cardiorrespiratória e à maximização da perda de peso nesta população. Verificou-se uma associação positiva entre a perda de peso e actividade física. Observou-se, ainda, que os participantes que relataram maior intensidade e mais tempo dispendido em actividade física/exercício físico apresentaram um aumento no consumo máximo de oxigénio no pós-operatório. Propõe-se, portanto, que a actividade física/exercício físico seja uma parte essencial de um programa de acompanhamento após cirurgia bariátrica.
In Portugal, 0.6% of adults are morbidly obese. As bariatric surgery has gained popularity in the treatment of this population, the main objective of this thesis is to examine the association between weight loss and physical activity habits in morbidly obese adults undergoing bariatric surgery. As a secondary objective we studied the association between current physical activity habits and weight loss, as well as its association with aerobic capacity in this population. This work is divided into two main parts, first a systematic literature review that summarized the effects of physical activity/exercise after bariatric surgery as part of a multidisciplinary approach. This evidences allowed establish the beneficial impacts of physical activity/exercise on anthropometric and body composition indicators, levels of physical activity/exercise, physical fitness, functional fitness, quality of life, and biochemical markers after bariatric surgery. And the second part of this research was an experimental study which involved 75 morbidly obese patients, between 18 and 65 years of age, undergoing bariatric surgery. The subjects answered a questionnaire on physical activity habits, which studied the habits of physical activity and its association with cardiorespiratory fitness and weight loss in this population. There was a positive association between weight loss and physical activity. And also, those participants who reported more time spent on physical activity/exercise and greater intensity showed an increase in maximal oxygen consumption postoperatively. It is suggested, therefore, that physical activity/exercise should be an essential part of the follow-up after bariatric surgery.
