INTRODUCTION: It is well documented that high blood @entity1255 ( @entity5784 ) levels possibly contribute to insulin resistance through the induction of resistin and inhibition of @entity1254 expression in mouce adipose tissue in vitro. Additionally, in @entity1 , @entity3562 has been recognized as an independent risk factor for @entity65 ( @entity65 ). AIM OF THE STUDY: Our study aimed at the evaluation of the relationship between total plasma @entity5784 levels and physical activity, @entity410 and dietary habits in young healthy @entity1 . MATERIAL AND METHODS: Plasma @entity5784 levels, macronutrient intake, maximal @entity26 uptake and physical activity were assessed in 65 volunteers. Physical activity was assessed using a Seven-Day Physical Activity Recall (SDPAR), maximal @entity26 uptake was measured on bicycle ergometer, and plasma @entity5784 was determined with the fluorescence polarization immunoassay (FPIA). Dietary habits were evaluated from dietary records collected over 4 days. On the basis of median @entity5784 levels (9.7  mol/l) two groups of subjects were separated - with plasma @entity5784 levels lower and higher than median value (Group LH and HH, respectively). RESULTS: Group LH and HH did not differ with respect to maximal @entity26 uptake or physical activity level. The only difference between groups with different circulating @entity5784 was the percentage of energy derived from protein - slightly but significantly higher in LH than in HH subjects (16% and 13% of total energy, respectively). CONCLUSIONS: At least in our @entity1 neither @entity410 nor physical activity affected circulating @entity5784 . However, higher percentage of energy derived from protein had a beneficial effect on plasma @entity5784 .
