Purpose: While electrolytes and immunity are highlighted as important in terms of the relationship between health and physical activity, immunoglobulin plays such a decisive role in the immune function that defends the human body, and it occurs in multiple tissues, such as the skin, lungs, blood, muscle, etc., affecting an increased risk of infection, including sleep deprivation, mental stress, malnutrition, and weight loss. Hence, this study was conducted to examine the effect of short-term weight loss on body composition and blood electrolyte and immunoglobulin concentrations among non-excellent and excellent Judo athletes. Method: The subjects of this study were 14 male athletes who were currently active as Judo athletes at university and had over 5 years of athlete experience and weight loss experience. For the statistical processing of this study, the mean and standard deviation for each item were calculated using the SPSS 12.0 statistical program, and the Two-way repeated ANOVA was performed according to group(non-excellent athlete and excellent athlete) and time (before the weight loss, 6 days after the weight loss, immediately after the competition, 30 minutes recovery period), and in the case of an interaction effect, the post-test was conducted by contrast test for each period and paired t-test for each period. Results: The changes in body weight(A), total weight without fat(B), and body fat percentage(C) are demon-strated before and after the weight loss(6 days), immediately after the competition, and 30 minutes in the recovery period(A). In terms of the change of body weight over time by group(A), both groups significantly decreased(p<.001) at the weight loss(6 days after) compared to before the weight loss. The changes in Ca(A), Na(B), K(C) and Mg(D) before and after the weight loss(6 days after), immediately after the competition, and 30 minutes of recovery are demonstrated. Comparing the change(A) of Ca between groups by group, both groups significantly decreased during the reduction period compared to before the weight loss(p<.001). The changes in IgA (A), changes in IgG(B), changes in IgM(C) and changes in IgD(D) are demonstrated before and after the weight loss(6 days), immediately after the competition, and after 30 minutes of recovery. Comparing the change in IgA between the periods by group, there was a significant increase in the excessive weight loss(after 6 days) in the excellent athlete group compared to before the weight loss(p<.001). Conclusion: Weight loss is considered to have a negative impact on performance improvement and affect the prematch condition and performance. Based on the results of this study, the scientific weight loss methods and appropriate short- and long-term weight loss will serve as the important basic data for further research to improve the athletic performance among the athletes of weight class.

Results: The re-establishment of Taekwondo is essential due to the theory of origin of Okinawa, but most Taekwondo people lack the recognition of historicality. Okinawa had close interaction with us in the Joseon Dynasty. This means that there are some reliably authentic documents and relics that are related to Subaks and party Subaks, that is, there should be an in-depth analysis on the historical recognition of the origin theory of Taekwondo in Okinawa. This can be a medium to open historical horizons to Taekwondo people.

Okinawa had close exchanges with us during the Joseon Dynasty, and when we saw it, there were credible ancient documents and artifacts that were related to Subaks and party trees. If Taekwondo academics do not present this, and go to this state, it may bring about a crisis of identity for the national Taekwondo physical education culture. Therefore, there should be a clear argument and a clear argument about Taekwondo history of Taekwondo history. Furthermore, we can present the right historical values and instill the right Taekwondo history education to our descendants.
