The aim of this study was to investigate adipocytokine responses to an single bout acute exercise in elite athletes with a low percentage of body fat, elite athletes with a high percentage of body fat and sedentary controls. Sixteen athletes with low percentage of body fat (volleyball players, low fat athletes group, LFAG), 15 athletes with high percentage of body fat (the elite water polo players, high fat athletes group, HFAG) and 15 sedentary subjects participated in this study (age (years) 20±2; 20±2; 20±1, respectively). All subjects were exposed to anthropometric measurements and one bout exercise test on treadmill in order to examine acute changes of adipocytokines. Blood samples were obtained at baseline levels, immediately after the exercise test and 30 min after recovery. Separated serum or plasma were used for hormone (leptin, adiponectin and visfatin) ELISA analysis. In athletes in LFAG, baseline leptin concentration was significantly lower, but adiponectin and visfatin concentrations were significantly higher, compared to sedentary controls and athletes in HFAG (P<0.05, all). There were no significant post exercise or recovery changes in adiponectin concentration (P>0.05). No differences in leptin concentration over time were observed in athletes groups (P>0.05). In contrast, leptin concentration in sedentary controls was significantly reduced after exercise and decreased even more during the recovery period (P<0.05). Only in athletes in HFAG, visfatin concentration increased significantly after exercise, but reduces in recovery period (P<0.05). In controls, visfatin concentration was significantly reduced and stayed lower throughout the recovery period (P<0.05). In conclusion, our findings show leptin and visfatin levels, but not adiponectin respond to acute exercise. Acute exercise elicited an inverse visfatin response in athletes in HFAG and controls. Also, these results suggest that leptin is altered after acute exercise only in sedentary individuals.
