Background: Cardiorespiratory fitness (CRF) is a measure of habitual physical activity level of an individual. We evaluate the association between CRF and measures of metabolic risk: Fatty Liver Index (FLI) and Lipid Accumulation Product (LAP).
Methods: This study evaluated 3,154 asymptomatic Brazilian subjects (43±10 years, 80% males) who had metabolic equivalent (METS) measured during routine health screen between November 2008 and July 2010. Both FLI and LAP were calculated from standardized algorithms.
Results: The prevalence of METS attained were classified into 3; category 1: METS ≤ 12 (44%, n=1,377), category 2 METS >12 & <14 (33%, n=1050) and category 3: METS ≥ 14 (23%, n=727). There was a steady decrease in both median FLI and LAP with higher CRF categories, Figure 1. A logistic regression analysis showed that higher fitness level was associated with lower LAP and FLI levels, see table 1.
Conclusions: Higher CRF level is associated with reduced cardiometabolic risk among asymptomatic individuals. This re-emphasis the importance of promoting increasing fitness level to improve health.
