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

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.

본 연구의 목적은 유도 경기력에 영향을 미칠 수 있는 선수들의 심리기술을 선정하고 이를 훈련을 통하여 최대한 향상시키고 현장에 활용할 수 있도록 도움을 주기 위한 것이다. 심리지원은 교육적 접근에 입각한 심리기술 훈련을 실시하였다. 우선 현재 실업 유도팀에서 활동하고 있는 11명의 선수를 대상으로 개별상담과 집단상담 및 처치 과정을 통하여 선수들에게 부족하거나 관심있는 심리적 요인을 자각시킨 후 10주간의 심리훈련이 시행되었다. 선수들이 자각한 중요도와 현재 상태를 평가한 결과 심리훈련의 필요성을 확연하였다. 8주의 심리훈련 결과 정신적 시연이 가장 많은 도움이 되었으며, 다음으로 자아조절, 긍정적 사고조절, 집중력 훈련, 이완, 스트레스, 에너지 조절 훈련 순으로 나타났다. 또한 앞으로 활용에서도 도움이 될 것으로 기대하고 있다.
