Objective: High level performances of elite athletes are affected by many physical, motoric and biochemical factors. Boxing is the one of the combat sports that requires a high level of physical capacity and skill. This study was conducted to examine some physical and oxidative stress parameters of athletes of Turkish National Boxing team during training camp.

Materials and Methods: The study was conducted on 29 boxers of Turkish Men Boxing National Team. A traininig program of eight weeks determined by the Boxing Federation prior to European Championship was applied to the study population. Some physical and biomotoric parameters (e.g. height, weight, body composition, vertical jumping, hand grip strength), and some oxidative parameters (e.g. malondialdehyde, 8-isoprostane, 4-hydroxynonenal, 8-hydroxy-2'-deoxyguanosine) of the participants were examined at the beginning and end of the training camp.

Results: Statistically significant differences (P<0,05) were determined in the parameters of body weight (pre-training camp: 67,44±3,02 kg- post-training camp: 68,44±3,02 kg), vertical jumping (pre-training camp: 43,05±1,83 cm- post-training camp: 44,55±1,81 cm), left hand grip strength (pre-training camp: 46,49±1,92 kg- post-training camp: 47,37±1,86 kg) and serum 8- isoprostane (pre-training camp: 93,02±2,6 pg/ml- post-training camp: 82,02±3,34 pg/ml). Although the levels of malondialdehyde, 4-hydroxynonenal and 8-hydroxy-2'-deoxyguanosine decreased, there were no statistically significant diiference when compared to pre-training period.(P> 0,05).

Conclusion: We believe that significant changes of some parameters in boxers measured before the training camp will make a positive contribution to their performance prior to the European Championship.
