In addition, leptin concentration is significantly associated with body mass index (BMI) Leptin, an obese (Ob) gene protein mainly secreted from adipose tissue, has been related to an increase in energy consumption, thermogenesis, and suppression of appetite (Campfield et al. Keywords: exercise time, heart disease, percent body fat, VO2max test Alteration in CRP and body fat percentage did not contribute to the change in leptin in these acute exercise models. The results of this study suggest that leptin and CRP do not differ among different exercise intensities. In addition, post-exercise leptin and CRP levels were not associated. s between leptin and CRP concentrations before and after exercise bouts corresponding to 65% and 85% Vo2max. While there were no significant differences in post-exercise leptin and CRP levels among the different exercise intensities, there were significant difference. Blood samples were collected before and immediately after each trial to analyze pre- and post-exercise leptin and CRP concentrations in the three trials. In addition to the Vo2max test, 13 male subjects (21.5 ± 1.8 years old, 18.5±4.0% body fat, 55.0☓.8 mL-kg-1 -min-1 Vo2max) exercised at two other exercise intensities (85% VO2max and 65% Vo2max) in a randomized order. Therefore, we investigated the effect of exercise intensity on serum leptin and CRP levels and compared changes and differences in both relationships with different exercise intensities. There seems to be a negative association between them, which may differ from the baseline however, no study has tested this assumption. In addition, leptin and CRP exhibit trends (downward and upward, respectively) after an acute bout of aerobic exercise. Although exercise intensity and duration may influence leptin and CRP concentrations, few studies have investigated this. Recently, serum leptin and C-reactive protein (CRP) levels have been regarded as independent predictive factors for heart disease.
