Difference in circulating FABP4 concentration between the venous and capillary blood in the resting (a) and exercising state (b). Data are presented as the mean ± standard deviation. There was no significant difference in circulating FABP4 concentration between the venous and capillary blood in the resting state (p = 0.178). A significant difference in circulating FABP4 concentration between the venous and capillary blood was observed in the exercising state (p < 0.001)
