The purpose of this study was to analyze the biomechanical differences of lower extremity joints of the frontal plane during sidestep cutting in male and female Judo athletes. In the knee and hip joint, the female group showed a smaller angle than the male group at the time of IC(initial contact). But peak knee joint adduction moment of female group was greater than male group(p<.05). Therefore, female Judo athletes were more likely to injure their knees at the point where their initial foot contacted the ground than male athletes during sidestep cutting.

The present study aimed to investigate rapid weight loss (RWL) and consequent physical and psychological challenges among judo athletes at the national athlete training center in 2017. The following results were obtained. Judo athletes used weight loss methods such as "gradually reduce meal portion," "skip meals," "limit water intake," "wear sweat suit for training," and "use sauna," and had physical and mental distress from such unhealthy weight management practices. Information about weight loss was obtained from "colleagues or senior athletes," "Internet," and "head coach or coach," and not experts such as nutritionists or physicians. Thus, athletes are recommended to employ healthy weight control methods based on advice from experts, such as nutritionists and physicians.

PURPOSE: This study was to investigate examined the differences in the autonomic nervous functions of elite female judo athletes according to their performance by measuring the heart rate variability (HRV). METHODS: Sixteen elite female judo players participated in this study. The participants were divided into a high performance and low performance group according to the results of their competitions. The HRV (mean heart rate, SDNN, RMSSD, TP, LF, HF, LF/HF ratio) was measured in the resting status. A t-test was used to compare the two groups, and bivariate logistic regression analysis was performed to determine the HRV elements that affect performance. The data were analyzed using IBM SPSS Statistics ver. 24.0 (IBM Co., Armonk, NY, USA). RESULTS: The mean heart rate was higher in the high performance group (72.88) than in the low performance group (64.75) (p=.049). The LF/HF ratio was higher in the high performance group (3.43) than in the low performance group (0.83), and the results were significant (p=.038). No HRV elements having a significant effect on the performance were observed. CONCLUSION: This study showed that the activity of the sympathetic nervous system was dominant in the high performance group in the resting status than in the low performance. The high performance group is believed to be in the overtraining status who experience more stress.

Background: The purpose of this study was to comparison and correlation between physical and psychological functions by gender in Judo athletes. Both the physical and psychological factors of athletes are important as factors influencing athletic performance, but there are few papers that have compared and studied the correlation between physical and psychological functions of judo players. Design: Cross sectional study Methods: The 134 participants; high school students, college students, and team players. They used physical functions to measure such as self-describing KOOS, FAOS, ODI, POMS, SCAT, ASMQ, and ACSI-28. Results: There was a significant difference in the physical function according to gender in the KOOS, but no significant difference in the FAOS and ODI. For psychological function, there was a significant difference in the vitality item in the POMS, and a significant difference in the body management, training management, life management, and unique behavior management items in the ASMQ. In the ACSI-28, there were significant differences in coping with adversity, stress repayment, concentration, freedom to worry about matches, and self-coaching behavior items. Physical function and psychological function showed a significant negative correlation. The POMS showed a negative correlation between the ASMQ and ACSI-28, whereas the SCAT showed a positive correlation. Conclusion: The results of this study are expected to be used as a basic data for sports training by gender of Judo athletes.

In regards to the category used in the measurement of bust somatotype, there are 48 types directly measured, 4 types indirectly measured, 7 types calculated and 1 bodyweight of type, making it 60 categories in total. The bust somatotype of a sports athlete and general person were compared together and after examining the characteristics of the bust somatotype, the somatotype of sports athlete was divided according to drop. The results of the study are as follows: 1. Questionnaire Results of the questionnaire showed that 63.4% of the respondents chose dress shirt as the most uncomfortable upper garment for athletes. And as for the result of the most uncomfortable body part turned out to be 'the neck is tight'. 2. Somatotype Analysis Results of direct, indirect measurement and the average somatotype of 97 National standard physique were compared. The characteristics of somatotype of athletes with well-developed upper body are that they are taller and have longer upper body and arms than the general person. And also the width of the trunk is wider, the girth bigger and the waist measure relatively slimmer. Looking at sports by category, it we could see that wrestlers were the largest neck parameter and width. Bodybuilders were the largest body parts for most categories. Weight lifting and Judo athletes were the largest waist and buttock. Canoe and rowing athletes were the largest height and arm parts. Dividing the somatotype of athletes according to drop, 72.8% of the research group belonged to the body type that resembled the letter Y.
