A game of basketball has been changed in many ways. In order to compete successfully in basketball today, players must be not only good skilled players, but well conditioned athletes. The purpose of this study was to examine the effects of 12-week anaerobic training during social basketball league with 20 male high school students aged 15~17. Hallow sprint training program as anaerobic training was consisted of 36 sessions; 3 supervised sessions per week for 12 consecutive weeks. Maximal oxygen uptake and percent maximal oxygen uptake at anaerobic threshold were measured before training, after training, during mid-season, and late-season, respectively. Maximal oxygen uptake levels of subjects were almost not changed but mean levels of anaerobic capacity were decreased after mid-season. Anaerobic training did not improve aerobic capacity so basketball players need to be trained both aerobically and anaerobically. Anaerobic training should riot be stopped when the season start.

PURPOSE: The purpose of this study was to investigate the impacts of Taekwondo-based combined exercise program for 12 weeks being aimed at growing children on basal physical fitness, neurotrophic factor, and working memory. METHODS: A total of 30, 5th grade male elementary students, who had no special past medical history and physical and/or emotional developmental disability and were healthy at the time, were selected for the study. The study groups were divided into a combined exercise group (CEG, n=15) and a control group (CG, n=15). The combined exercise program was consisted of Taekwondo movement as a basic program, and training frequency was 5 times weekly, of which training time was a total of 60 minutes each time. RESULTS: First, the complex training program for 12 weeks resulted in the improvements of basal physical fitness in the combined exercise group comparing with the control group, such as muscle endurance, cardiopulmonary endurance and agility. Second, in the case of BDNF, brain-derived neurotrophic factor, although there was an increasing trend in the combined exercise group comparing with the control group, no statistically significant difference between them. In the case of NGF, it was shown that there was a statistically significant increase in the combined exercise group comparing with the control group. Third, in the working memory, there was no statistically significant difference between the combined exercise group and the control group. As shown above, while the basal physical fitness was improved and the concentration of NGF increased through the combined exercise program for 12 weeks being aimed at growing children, this program didn``t have an impact on the improvement of BDNF and working memory. CONCLUSIONS: In conclusion, it is considered that the applying training program including a learning task rather than the training program occurring simple movements repeatedly is practically helpful to enhance the brain function in growing children.

박명수(Park Myoung Soo),김병완(Kim Byeong Wan) 세계태권도문화학회 2012 세계태권도문화학회지 Vol.- No.5

본 연구는 태권도 시범단원의 인식을 조사 연구하여 태권도 시범 프로그램의 수준향상에 기여하고자 경기도에 소재한 중학교, 고등학교, 대학교 태권도 시범단원 각각 100명씩 총 300명을 대상으로 태권도 시범 시 갖춰야할 요소, 태권도 시범에 대한 인식, 태권도 프로그램에 대한 인식에 대해 설문지법으로 조사 분석한 결과 다음과 같은 결론을 얻었다. 시범단원이 갖춰야할 요소에서 하루 평균 수련시간, 우선시 되는 체력요소, 갖춰야할 중요 기술력, 시범을 잘 하기 위한 방법 등에 대해서 살펴보았는데, 평균 수련시간은 3-4시간이 적절하다고 하였고, 체력요소는 지구력, 순발력이라고 응답하였다. 또한 시범을 잘 하기 위한 방법은 꾸준히 노력하는 것이라고 모두 응답하였다. 시범에 대한 인식에서 시범 시 가장 어려운 기술, 주된 기술, 호응이 좋은 기술로는 공중 뒤돌아차기, 고난이도 기술격파라고 하였고, 호응이 별로인 것은 기본 발차기와 기본 격파라고 응답했는데 이유는 단순하다는 것이었다. 태권도 프로그램에 대한 인식에서 시범 프로그램을 구성한 경험 유무에서는 163명이 구성 경험이 있다고 했으며, 이들 중 대부분이 내용을 구성하는 것이 가장 어려웠다고 이야기 하였다. 태권도 기술의 발전 유무에서는 전체적으로 발전하고는 있지만 좀 더 분발의 필요성을 이야기했고, 특히 새로운 기술 분야나 프로그램 개발의 발전이 필요한 것으로 나타났다. This study conducted a questionnaire survey research for its objectives to make contribution for level up of Taekwondo Demonstrative Program by studying on the recognition of the member affiliate to the Taekwondo Demonstration Team. The questionnaire survey was performed th the sample group of 300 members in total consisted of each 100 samples from the Taekwondo Demonstration Team of middle school, high school and university. The items of questionnaire survey were the elements to prepare for Taekwondo Demonstration, recognition on Taekwondo Demonstration, and recognition on Taekwondo Program, and from the results of survey research, following conclusion has been derived. For the elements to be prepared by the demonstrating member, the average daily training hours, physical strength factors that are being prioritized, important techniques to be equipped with, the method to present good demonstration were studied. From the result, for average training hours, 3-4 hours were answered as suitable, for physical strength factors, the answers were stamina, and quickness. Also for the mithod to present good demonstration, the responded answer by all was to work steadily. As the most difficult technique, key technique, and well responded techniques, the answers were the back tumbling kick(Gongjung MomDola Chagi) and high difficulty level technical breaking, and those with poor response were answered as th basic kicks and the basic breaking with reason that they are too simple. High Difficulty Technical Breaking were 163 subjects answered that they have experiences in composition of demonstration program from the question about any experience for the program composition in the recognition on the Taekwondo Program. Majority of these responders also told that the composition of contents was the most difficult part. For the development of Taekwondo techniques, it suggested that in overall that are being advanced, yet there is a need for more strenuous efforts, and in particular, it was indicated that advancement is required in the new technique field or in program development
