The purpose of this study was to investigate the effects of a winter training camp on physical fitness, physical self-efficacy and nutrients intake in juvenile Taekwondo players. Sixty three subjects of male middle school student Taekwondo players participated in this study. Before and after attending Taekwondo winter training camp, Taekwondo related fitness and physical self efficacy and nutrients intake of subjects were measured and compared. The results of this study were as follows: 1) There were significantly improvements (p<0.001) in 1200m run, sit up, push up. 2) There was no significantly change in physical self efficacy. 3) There were significantly increase intakes (p<0.001) in total calorie, protein, fat, fiber, Ca, P, K, vitamin A, vitamin B2, vitamin B6, niacin, vitamin C and vitamin E. However, index of nutritional quality in fiber, Ca, K, vitamin A had not good assessment. These results suggested that a winter training seems necessary to keep psychological management and scientific dietary management as well as physical training in juvenile Taekwondo players.

Background: To investigate how many rookie pitchers suffered from injuries while playing in the amateur league without guidelines for prevention of excessive pitching, we analyzed their amateur pitching patterns based on the pitch count, use of breaking balls, and pitches during winter camp. Methods: Forty-one rookie pitchers who graduated from high school or university in 2013 and joined professional baseball teams. Participants were interviewed by a trainer using our questionnaire. Injury inclusion criteria were 1) history of shoulder surgery, 2) history of elbow surgery, 3) shoulder pain requiring treatment, and 4) elbow pain requiring treatment. Results: Mean number of pitches per game and warm-up pitches for practice was 84.5 pitches (range, 15 to 130 pitches) and 16.4 pitches (range, 2 to 210 pitches), respectively. Mean number of pitches during the last year was 906.9 (range, 80 to 2,000). Mean number of maximal pitches was 127 pitches (range, 50 to 210 pitches). Fourteen pitchers had pitched over 150 pitches. Twenty-seven pitchers (65.9%) had pitched in spite of enduring pain. During winter training (mean 1.8 months), mean number of pitches per day was 162.5 pitches, and 20 pitchers (48.8%) had practiced pitching excessively despite the cold weather. Twenty-six rookies (63.4%) had shoulder pain or history of shoulder surgery, and 31 pitchers (75.6%) had elbow pain or history of elbow surgery. Only four participants (9.8%) did not have pain and history of surgery. Conclusions: For young baseball pitchers, guidelines for prevention of excessive pitching and for regulating the winter training program may be needed.

The purpose of this study was to provide the basic information on nutritional condition for improving performance of the national junior rowing team players(male n=17, female n=14). To attain this purpose, their body composition and energy intake situations were investigated during their three-week winter training camp. Measurement of body composition measured by the interval, and two days, and dietary intake in this study to investigate the type and amount of food, the researchers measured directly, and then refer to the record subjects to investigate the dietary intake and the adoption of a Weighing Method. The result is as follows. During training, body composition due to the high intensity training to maintain a properly balanced diet is the consumption of energy, weight and body composition has a positive influence. The male players' average energy intake is 5,951.6 kcal(72.6 kcal/kgBW, 150%), the rate of the three main nutrients, carbohydrate, fat, protein, is 72.6 : 8.7 : 18.7 respectively. For the female, the average energy intake is 3,685.6 kcal(51.8 kcal/kgBW, 121%), and the rate of the three main nutrients is 76.3 : 8.5 : 15.2. Both of male and female were taken sufficient Vitamin, mineral and other nutrient according to %RI(recommended intake). Based on the results of a survey of elite athletes and nutrition management and the systematic introduction and review of the program in conjunction with a professional nutritionist would need, and can also be applied to expand the school to the scene, the reality of the program review and development of qualified need.

본 연구는 2009년 7월부터 2010년 2월까지 실시된 부산대학교 체육영재센터의 체육영재양성 사업에 참가한 스포츠심리 분야의 현장사례 연구이다. 부산대 체육영재센터는 부산 울산 경남의 초등학교 1,2,3 학년 중 남 여 구분없이 학교장의 추천을 받아 3차에 걸친 운동능력 검사와 운동적합률 검사를 통해 60명(육상:40명, 수영:10명, 체조: 10명)의 체육영재를 선발하여 운영하였다. 하계 및 동계 캠프와 매주 토요일을 활용하여 종목별 전문훈련을 진행하였다. 스포츠 심리학 분야에서는 몇 가지 실험적인 현장적용을 시도하였고, 다음과 같은 시사점을 얻을 수 있었다. 첫째, 초등학교 저학년들의 경우에는 보충설명을 제공하면 검사지를 통한 심리측정이 가능하고, 3학년의 경우는 추가 설명이 없어도 충분히 실시할 수 있었다. 둘째, 다중지능검사는 체육영재들의 지능을 검사하는 방법으로 유용하며, 심리상담 기초자료로써 효휼성이 높았다. 셋째, 체육영재들의 성격은 대체로 외향적이면서 직관과 감정을 선호하는 것으로 제시되었다. 넷째, FAIR 집중력 검사에서는 사후 측정 시 유의하게 향상된 것으로 제시되어, 체육영재 프로그램이 주의 집중력을 높이는데 긍정적으로 작용하였다. 다섯째, 자체 개발한 체육과제 집착력 검사지와 체육활동 자기관리 검사지는 추가적인 타당도와 신뢰도 검사과정을 거친다면 공식적인 심리측정 도구로 활용될 수 있다는 가능성을 발견하였다.
