훅 불면 날아갈 것 같은 가냘픈 체구의 소녀가 2010년 광저우 아시안게임에서 값진 동메달을 거는 모습을 기억하는가? 한국 리듬체조 역사상 처음으로 개인종합 동메달을 따낸 순간이었다. 2년이 지난 지금 손연재는 국제체조연맹(FIG) 세계랭킹 5위까지 올라가며 이제 대한민국을 뛰어넘어 세계 톱클래스 선수로 인정받기에 이르렀다.

The study has a goal that produces abundant documents that needed for athletes to teach and progress skills by analyzing 3-dimensional action analysis of C-difficulties Ring jump included in body original elements among techniques constructing Rhythmic Sport Gymnastics. 1. It was the longest applied time delay that E-3 indicates 0.409${\pm}$0.017sec in each event applied time delay. 2. It was the tallest height that E-3 indicates 88.5${\pm}$1.3% in displacement of body's center. 3. It was the fastest velocity in E-2 where the velocity of left foot is 732.4${\pm}$46.1cm/sec, the velocity of right foot is 1958.4${\pm}$25.1cm/sec. 4. the lowest angle was founded at 97.8 degree in the E-3 on the trunk extension angle. 5. The lowest angle of both sides were seen at 92.8${\pm}$14.9degree and 69.2${\pm}$5.7degree in the E-3 on the each displacement of knee joint. 6. The highest angle of both sides were seen at 171.3${\pm}$6.9degree and 167.9${\pm}$8.4degree in the E-3 on the each displacement of ankle joint As a result of these studies, by jumping with ankle joint extension to accomplish the Ring jump action, it is considered to have the time of flexiblity and staying in the air which we can see in a back.

This study was conducted with 202 elderly people aged 65 years or older (40.6% male and 59.4% female) participating in physical activities centered on line dance and rhythmic gymnastics. To achieve the main objectives of the study, a questionnaire for mature aging attitude, depression and successful aging was used. The results are as follows. First, matured aging attitude influenced negatively on depression. Second, matured aging attitude influenced positively on successful aging. Third, depression influenced negatively on successful aging. Based on the above results, it is necessary to encourage the elderly to participate in physical activities to achieve successful aging through active interventions against depression.

The analysis in this work is about costumes among the rhythmic gymnasts in competition, which is intended to develop designs about rhythmic gymnastics costume and provide the basic material from the results. In its research method and range, the general information on rhythmic gymnastics was reviewed in literature and the case analysis was followed about costumes of world high rankers in competition during 2012~2015 seasons. Research showed the following results. First, leotard took a shape of skirt-added one-piece type, where a combination with long tight sleeve, round neck line, and stand-up collar had a relatively higher percentage in design. With regard to a bottom line of skirt, an amorphous type was most common that highlights rhythmical beauty without any particular form. This design exposed shoulders and waists on both sides, expressing the feminine beauty. Second, in color used mainly, white appeared most frequently. In its combination, more than three were employed. Third, transparent mesh was applied as basic, where lace and chiffon were used. Abstract pattern took the highest portion in pattern. Particularly, crystal bead or gradation coloring was used to maximize the visually splendid image, giving an effect of optical illusion as if neckless clothing, choker, bracelet, or glove were worn. Fourth, it appeared that the costume for each event was changed in every season, when only music was substituted but the same earlier costume was put on for the different event.

Taekwon dancing was a program developed to popularize Taekwondo. The purpose of this study is to examine the research trend of Taekwondo dancing to understand academic value and purpose. To accomplish this goal, this study analyzed 46 article published in 26 journals. Data analysis was performed using the IBM SPSS 23.0 program, which was divided into research subjects, research methods, and research subjects. The results were as follows. First, in the research area, the study was consistently published in exercise physiology / prescription area, and recently studies have been published in the field of sports pedagogy. Second, quantitative research was conducted more than qualitative research in research methods. In the quantitative research, the research that verified the difference between the groups was published the most. in the qualitative research, literature research was the most. Finally, in the study subjects, most studies were conducted on people, by subgroup, the study was published in many order of adult, elderly, middle school students. In the analysis of the data, literature, web-site news and so on were analyzed, other study was analyzed the program system in computer games.

This study was analyzed the characteristics on the stability of posture while conducting a through two and half rotation technic of pench$\acute{e}$ in rhythmic gymnastics. Two rhythmical gymnastics player(LKH and SSJ) who is a member of the national team were selected, and for obtain the kinematic and kinetic variables were used a ProReflex MCU 240 infrared camera(Qualisys, Sweden) and a Type9286A force platform(Kistler, Switzerland). The mechanical factors were computed by using Visual3D program and Matlab R2009a. During the landing and rotation phase the results showed following characteristics; 1) In medial-lateral and horizontal displacement of the support foot, LKH showed smaller movement than SSJ, but SSJ showed smaller movement than LKH in swing foot. LKH showed bigger movement in medial-lateral axis of COP and vertical axis of COG, but SSJ showed bigger movement in horizontal axis of COP and medial-lateral axis of COG. 2) SSJ showed bigger maximum horizontal and vertical velocity at P1 and P2 than LKH. 3) In the inclination angle of COP and COG, SSJ showed smaller change than LKH, but within medial-lateral tilt of the shoulder, LKH performed rotation motion in horizontal position than SSJ. There was no differences in each force components during rotation, but on landing phase, the results showed a characteristic that SSJ exerted bigger breaking force and vertical force than LKH.

The objectives of this study were to investigate 1) the foods intake as well as nutrients intake, 2) the nutritional knowledge, and 3) the relations between the foods and nutrients intakes and nutritional knowledge in adolescent rhythmic gymnasts (RGs). The results are summarized as follows. Average daily intakes of energy, calcium, iron, vitamin A, vitamin B$_1$ vitamin B$_2$ and niacin were in 45-74％ of the RDAs for Koreans. Average daily energy intake was only about 50％ of energy expenditure by physical activities. Average daily intakes of each food group were generally lower, but intakes of breads and confectionaries, sugar and sweets, milks and dairy products, and instant foods were higher in the RGs compared to the nonathletic students of the same age from the National Health and Nutrition Suvey. The contribution of empty-calorie foods such as breads and confectionaries, beverage and instant foods to the major energy nutrients were high. Mean of total nutritional knowledge score of RGs was 28.4 of total score 50. In categorical score of nutritional knowledge, the RGs make a best score on food sources and they get the lowest marks for food exchange. Among the nutrients, intakes of crude fiber, animal Fe, Na, K, vitamin A, carotene, vitamin B$_1$ niacin and vitamin C and, among the food groups, intakes of mushrooms, fruits and meats had relations with one of the total or categorical nutritional knowledge scores in the RGs. In conclusion, nutritional status of adolescent RGs was poor due to their unbalanced diet composed of empty-calorie foods, and their undesirable food intake pattern was supposed to be related to the low nutritional knowledge score of them. These results indicate that the RGs should be given more nutritional knowledge to improve their nutritional status and the exercise performance.
