Effect of Diet and Exercise on the Peripheral Immune System in Young Balb/c Mice

Figure 3

Serum leptin. The sedentary and exercised mice showed a higher plasmatic level of leptin with carbohydrate-rich and fat-rich diets compared to animals with the standard diet. For exercised mice, the increase in leptin was greater with a fat-rich than carbohydrate-rich diet. Compared to sedentary mice, exercised animals had a lower level of leptin when fed with a standard or carbohydrate-rich diet, but they had a higher level of this hormone when given a fat-rich diet. Determination was made by ELISA at the end of the experiment (Bonferroni test ; ). Data are expressed as the mean ± SD ( per treatment group).
