Background and aim: Wrestling success depends on power, power endurance, and maximum strength, muscular endurance of short duration, flexibility as well as technique and tactical skills. Weight control and weight loss are also very important issues in the view of wrestling success. In this study, it was aimed to investigate the anthropometric features, serum lipoproteins, glucose homeostasis and leptin levels in Turkish National Senior Wrestlers and healthy sedentary males.

Material and method: Totally, 45 National senior wrestlers in Olympic Camp before Beijing 2008, and sedentary and healthy-volunteers group from university students were selected for comparison. Anthropometric and physiological features including age, body weight, body height and body mass index (BMI) as well as metabolic features including fasting glucose, insulin, leptin and lipoprotein levels with HOMA values were measured and compared with the results of sedentary group.

Results: Wrestlers had significantly higher insulin and triglycerides levels with HOMA values in fasting than healthy males. However, the wrestlers’ HDL-cholesterol was found high while it was low in LDL cholesterol. There was only positive correlation between leptin and fasting insulin level.

Conclusion: This study shown that wrestlers have decreased insulin sensitivity including higher fasting insulin and HOMA values with higher triglycerides levels than sedentary males.
