Description

Two cases of so-called march hemoglobinuria caused by “kendo” exercise were described and the mechanism of hemolysis was discussed. Two 15-year-old high schoolboys had episodes of passing dark brown urine in April 1977 after an exercise of “Kendo.” They had further attacks of hemoglobinuria during these two or five months.<br>They showed no abnormalities in physical and laboratory examinations. A hemoglobinuria was proved after an exercise of “fumikomi” for one or one and a half hours, and an increase in serum hemoglobin level was observed prior to hemoglobinuria.<br>The medical students, who belong to “kendo” club and had noticed hemoglobinuria by themselves, played “kendo” for one hour, and mild hemoglobinemia was found in these students.<br>It is suggested that “kendo” exercise can produce traumatic damage to erythrocytes to a certain extent even in normal individuals.
