This study was designed to investigate the physiological effects of certain judo moves as measured by changes in the rate of urinary ion excretion after three typical judo moves (nagewaza, katamewaza and uchikomi). The subjects were six male university judo players. The subjects performed a typical 10-minute moves on separate days. The results are summarized as follows:1) All three moves brought about a reduction in urinary sodium ion (Na+) excretion but had no natriuretic effects on the subjects.2) All three moves brought about a reduction in urinary chloride ion (Cl-) excretion in the subjects.3) Urinary flow and Cl- excretion rates were closely correlated with the Na+ excretion rate (r=0.920 and r=0.972 both p< 0.001). These results indicate that the subjects performed the 10-minute series of judo moves with lower lactic acid oxygen debt than normally seen in anaerobic exercise.
