This research applied the short-term diet control and training program to target the seven Judo professionals who often reduce weight in a short period of time and seven members of the social club who have no experience with excessive weight reduction in order to analyze immunity function in the body after a match and the excessive short-term weight reduction. The following conclusions were reached. 1. Change in the physical formation 1) As for the change in the weight, it decreased significantly in the two groups during the excessive reduction period, but it increased significantly due to the moisture absorption after five minute-long match, resulting from excessive reduction(after six days). There was no change in case of recovery period. 2) As for the change in the amount of muscle, it decreased significantly for the two groups during excessive reduction period, but there was no change after five minute-long match in case of excessive reduction (after six days). 3) As for the change in the amount of body fat and body fat rate, they decreased significantly for the two groups during excessive reduction period. As for the excessive reduction(after six days), it increased after five minute-long match due to moisture absorption. There was no change in case of group of Judo professionals during recovery period, but it increased significantly in the group comprised of aficionados. 2. Change in the immunity function 1) As for the changes in the IgA, IgG and IgM, they were high for the group of Judo professionals during excessive reduction period, but there was no significant change in the group comprised of aficionados. In the two groups, they were high after five minute-long match for the excessive reduction (after six days), and they were low during recovery period. 2) As for the change in the IgD, it was high in the two groups during excessive reduction period, but there was no change during recovery period after five minute-long match when it comes to the excessive reduction (after six days). However, it was significantly high after excessive reduction, after a match and during recovery period in the group of Judo professionals compared to the group comprised of aficionados. The above mentioned results show that the Judo professionals in Korea can reduce weight excessively in a short period of time, with in 6-7% of the weight. However, when this weight reduction is continued for a long time, this can cause abnormal state. Thus, when the short-term weight reduction continues, it can exert negative impact immunity functions. Although there are differences in case of the Judo professionals depending on the individuals physical state and characteristics when it comes to the excessive short-term weight reduction, excessive weight reduction can produce negative results when it comes to the improvement of competition ability and on the condition before competition as well as competition ability. Result of this research will be leveraged, to produce important base data for conducting additional research to ensure improvement of competition ability when professionals exercise, following the scientific reduction method and appropriate short and long term periods for weight reduction.
