In an attempt to clarify the influence of lung volume and water temperature on the heart rate response during apneic face immersion in the trained athletes, 10 soccer players were studied while holding their breath as long as possible after full inspiration(TLC), full expiration(RV) or normal breath(FRC) with face immersion in water. The electrocardiogram(Lead II) was recorded before and during each manuever and compared with 20 control subjects. The results are summarized as follows; 1) Resting heart rate was significantly lower in the athletes than that of the control groups. 2) During apneic face immersion, severe bradycardia were observed in both groups and the heart rate was significantly lower in the athletes than that of the control groups. 3) The degree of the bradycardia (maximum percent reduction of heart rate, HRmax.) were inversely propotional to the lung volume and water temperature. In the above results, bradycardial response was more sensitive in the athletes than the control. It was suggested that diving bradycardia was related to the gas content in the lung and reflex from the cold receptor in the face.

본 연구의 목적은 운동부 성폭력 실태 분석을 통하여 성폭력 문제 해결을 위한 시사점을 도출하는데 있다. 이를 위하여 본 조사는 2010년 대한체육회에 등록된 전국 초 중 고 및 대학 일반 운동선수와 지도자 및 학부모 등 총 2,041명을 대상으로 실시하였다. 본 연구의 내용은 첫째, 최근 1년간의 성폭력 실태를 파악하였고, 둘째, 운동선수들의 성폭력에 대한 대처 및 태도를 중심으로 근원적인 문제점을 분석하였으며, 마지막으로 성폭력에 대한 예방실태를 바탕으로 문제해결을 위한 조사를 실시하였다. 본 연구는 성폭력 실태를 통하여 성폭력 방지를 위한 정책 수립에 대한 기초자료를 제공하는데 그 연구의 가치가 있다고 할 수 있다. 결과적으로 운동부 성폭력은 단순한 선수 개인의 문제가 아니라, 학교, 가정, 지역사회, 정부 등 여러 가지 요소가 결합되어 나타나는 종합적인 문제이기 때문에 유관단체들의 종합적이고 체계적인 대책이 필요하다는 시사점을 도출하였다.

With the aging of society a great deal of interest is being placed on the value of longitudinal data in evaluating physiological losses. We present data on test-one/test-two reliability and reproducibility for measures of training, bone density from a longitudinal study of master athletes. Fifty-two males (mean age at test $1=58.2{\pm}9.8\;years$) and thirty-two females ($54.4{\pm}8.8\;years$) were selected from the study population. Bone mineral density was determined using DEXA (Hologic 1500). The characteristics of the subjects are presented below as $means\;{\pm}\;S.D$. The data was imported into the Statistical Package for the Social Science (SPSS 9.0, Chicago, IL). Paired t-tests were performed between visit 1 and visit 2 in subjects. Pearson correlations were performed. The results of this study indicate the measures of training history, body mass and bone density are reasonably stable and reproducible. We conclude that body composition and bone density parameters are stable and reproducible over time in active older subjects. Physiologic measures in master athletes are fairly stable, and reproducible over time Longitudinal studies investigating age-related changes in master athletes need to be conducted on a time schedule of greater than two years.

Background: Ankle sprain in the Lead Leg Side (ALLS) is common in fencing athletes, and studies comparing the ankle range of motion (ROM) and strength of both legs are insufficient. Objectvies: To compare the ankle ROM and hip strength between two legs in fencing athletes who has ankle instability in the lead leg side. Design: Cross-sectional design. Methods: Seven fencing athletes with ankle instability participated in this study, and they randomly assigned into ankle in the Lead Leg Side (ALLS) and ankle in the Rear Leg Side (ARLS). Instability was determined by the Cumberland Ankle Instability Tool (CAIT), and then joint ROM and hip muscle strength were measured. Results: There were significant differences in dorsiflexion ROM, hip strength (extension and abduction) between the ALLS with ankle instability and ARLS (P<.05). Conclusion: This study suggests that the ankle ROM and hip muscle strength of ARLS are greater than ALLS in fencing athletes with ankle instability.

This epidemiological study aims to determine the incidence, areas, severity, and time of occurrence of sports injuries in elite female rowing athletes who were training at the Jincheon National Training Center for a 1-year period from January 1st to December 31st, 2017. According to the daily injury reports form of the IOC, sport events, weight division, injured area, and cause of injury were recorded, and the following results were found. Upon comparing the incidence of sports injuries, there was a significant difference in weight of double scull athletes. In terms of sports, there was a significant difference between pair and athletes who played double skull. Injuries occurred most commonly in the lower extremity (40.5%), followed by the trunk (35.1%), upper extremity (24.3%). for all athletes in rowing. The knee and lumbar spine/lower back were the most common injury sites. More than 60% of all injuries were Level III, and injuries occurred most frequently during training, followed by weight training and then competition.

[Purpose] Functional beverages are intended to support those who want to maintain optimal physical condition and improve their quality of life through the enhancement of heart health, immunity, and digestion. The purpose of this study was to investigate the performance of top-level athletes consuming immune-strengthening conditioning nutritional drinks. [Methods] A total of 107 top-level athletes (baseball (56 players), pro volleyball (17), athletics (16), cycling (8), golf (6), and fencing (6)) participated in the experiment. They consumed an immune-enhancing functional beverage once a day for 8 weeks and responded to a survey before, during, and after drinking the beverage. [Results] Three total aspect-based subfactors were drawn from 24 questions in the factor analysis: physical, satisfaction with mental stability, and activity in performance. The physical, mental stability and performance changes of athletes significantly increased in period 2 (4 weeks after intake) and period 3 (after 8 weeks of intake). [Conclusion] We evaluated the efficacy of a new conditioned beverage containing Lactobacillus B240 and protein in improving the performance and physiological utility of top athletes. This functional drink may gain popularity among those seeking health benefits and improved exercise performance.

The purpose of this study is to verify the research model and identify the causal relationship among leader's super leadership, self-leadership, psychological empowerment, sport commitment and performance perceived by Taekwondo athletes. The subjects of the study were middle and high school Taekwondo athletes registered in the Korea Taekwondo Association in 2020 and 2021, and data from 454 people were used as final effective samples through convenience sampling. The collected data used the SPSS 23.0 version and the Amos 21.0 version to verify the hypothesis. As a result, the following conclusions were obtained. First, we discovered that the leader's super leadership had a positive impact on the athlete's self-leadership, psychological empowerment, and sport commitment. Second, we found that the athlete's self-leadership had a positive effect on psychological empowerment, sport commitment, and performance. Third, we found that athlete's psychological empowerment had a positive effect on sport commitment and performance. Fourth, we found that the athlete's sport commitment had a negative effect on performance. Therefore, this study has reminded us about importance of psychological empowerment and sport commitment for explaining the relationship between leadership type and performance perceived by Taekwondo athletes, and might contribute to the theoretical discussion of variables related to athletes' performance.

The purpose of this study was to investigate preferences of foreign athletes staying in the Athletic Village for '86 Asian Olympic Games for Korean traditional foods as served in the restaurant. A survey was conducted to 762 foreign athletes that selected Korean traditional foods in Athletic Village restaurants, from September 16 to 24, 1986. Most people preferred Korean traditional foods for its taste. Yachae Bokkum (Sauted Vegetable), Jonbok Juk (Rice Porridge of Abalone), Kimchi, Usol Chim (Tongue Stew), Dak Juk (Rice Porridge of Chicken) were preferred by most foreign athletes. Chongpo Muk (Mung Bean Starch Jelly), Toran Guk (Taro Soup) were not preferred. They proposed improvement of salty, hot and strong spicy taste in Korean traditional foods.
