The purpose of this research is to evaluate the effect of selective fighting competitions (kumite) on urinary albumin, total protein, β2-microglobulin, creatinine, sodium and potassium levels in male members of the professional national karate team. A questionnaire was presented to 40 champions, with necessary explanations. They were invited to a national team selection camp, and 18 subjects, who had frequently won championships, who were in good-health, and free from using drugs or ergogenic aids, and with similar participation were selected to be tested. They were aged 19 yrs old, with an average body weight of 67 kg, and average height of 170 cm. Their urine samples were examined 24 hours before and following competition to obtain aforementioned parameter levels. Statistics were performed using the SPSS software. Urinary total protein, albumin, creatinine, β2-microglobulin contents were meaningfully affected following karate competitions, whereas sodium and potassium levels were not altered to such an extent.
