This paper attempts to investigate the characteristics of athletic power in Judo player by measuring active and passive grip strength, which dynamometer has never showned. The result is as follows; 1) In active grip strength there is no any difference between dominant hand and the other hand. But in passive grip strength dominant hand is greater than the other hand. 2) We cannot find any difference between active and passive grip strength when Judo player tries to do HIKITE or TSURITE. 3) Judo group proved to have much more power in deep gripping than in shallow gripping. 4) We find active grip strength has plus (+) relationship with passive grip strength. But there seems to be minus (-) relationship in percentage (%) between active grip strength and passive grip strength. 5) In case of deep gripping; The percentage of the passive grip strength to the active one on the dominant hand is shown as 297.7%, on the other hand 285.6% in Judo group. In the general group 248.l% on the dominant hand, 235.8% on the other hand. In the gymnast group 290.8% on the dominant hand, 309.9% on the other hand. 6) In case of shallow gripping; In Judo group the percentage of the passive grip strength to the active one on the dominant handis shown as 244.5%, 241.5% on the other hand. In the general group 208.2% on the dominant hand, 211.5% on the other hand. In the gymnast group 279.2% on the dominant hand, 288% on the other hand.
