The purpose of this study is to investigate the levels of selenium and chromium in blood in well-trained male rowers of Turkish national team during and after an aerobic maximal exercise. Eleven well-trained young male completed the exercise protocol. Blood samples were collected before the exercise, immediately after exercise, and one hour after the exercise. Blood was analyzed for Se and Cr by using inductively coupled plasma optical emission spectrometry (ICP-OES) method. Although there were no statistically differences between the pre and post Cr levels (P > 0.05), the levels observed one hour after the exercise showed statistically significant changes compared to the pre and post exercise values (P < 0.05). There was no change of statistical relevance in Se levels (P > 0.05).
