摘要：A síndrome metabólica (SM) é definida pela presença de, ao menos três, dentre cinco fatores de risco cardiovascular: hiperglicemia, resistência à insulina, obesidade, dislipidemia e pressão arterial elevada. Embora portadores de SM apresentem baixa aptidão física e pior qualidade de vida (QV), quando comparado aos indivíduos sem SM, ainda não foram investigadas as correlações entre a aptidão física e a QV em mulheres com SM. O objetivo do presente estudo foi comparar a QV, força muscular e aptidão aeróbia, bem como analisar a correlação entre a QV e a aptidão física de mulheres com e sem SM. Participaram do estudo 49 mulheres, 21 com SM (33.5 ± 9.1 anos) e 28 sem SM (32.3 ± 7.9 anos). Para avaliação da QV, aptidão aeróbia e força muscular foram utilizados, respectivamente, o questionário Short Form Health Survey 36 (SF-36), o teste de caminhada de 6 minutos (6-C) e o teste de preensão manual. As mulheres com SM apresentaram pior QV, percorreram menor distância no 6-C e obtiveram menor força muscular relativa. Foi observada correlação positiva entre a aptidão aeróbia e quatro domínios da QV: capacidade funcional, limitação por aspectos físicos, dor e aspectos sociais da funcionalidade. Mulheres com SM apresentam menor de força muscular e aptidão aeróbia, bem como piores escores de QV no estado de saúde geral, capacidade funcional, dor no corpo, limitação por aspectos emocionais, aspectos sociais da funcionalidade e limitação por aspectos físicos quando comparado com mulheres sem SM.
其他摘要：The metabolic syndrome (MetS) is defined as the presence of at least three out of five cardiovascular risk factors: hiperglicemia, insulin resistance, abdominal obesity, dyslipidemia and elevated blood pressure. Subjects with MetS still present worse perception of quality of life (QL) and low physical fitness as compared with subjects without MetS. However, correlations between physical fitness and QL have not been investigated in subjects with MetS. The aim of the present study was to compare the QL, muscle strength and aerobic fitness, as well as to analyse the correlatation between the QL and physical fitness in women with and without MetS. Forty-nine women, 21 with MetS (33.5 ± 9.1 years) and 28 without MetS (32.3 ± 7.9 years) were studied. Perception of QL, physical fitness and muscle strength were evaluated by the Short Form Health Survey 36 (SF-36), the distance covered in the 6 minute walk test (6MWT), and the handgrip test, respectively. Women with MetS presented worse perception of QL, covered a lower distance during the 6MWT and exhibited lower relative muscle strength. Additionally there was a positive correlation of aerobic fitness with four domains of QL: functional capacity, limitation by physical aspect, pain and social aspects. Women with MetS present lower muscle strength and aerobic fitness, as well as lower QL scores for the general health state, functional capacity, body pain, limitation by emotional aspects, social aspects of functionality and limitation by physical aspects as compared with women without MetS.
