체육학에서 운동역학 및 초등체육 관련 운동역학 연구의 현실과 문제점을 알아보고 활성화 시킬 수 있는 방안에대해서 알아보고자 하였다. 한국체육학회지, 한국운동역학회지, 그리고 한국초등체육학회지에 게재된 논문을 대상으로 분석한 결과는 다음과 같다. 최근 3년(2012~2014)간 운동역학 관련 연구를 분석한 결과, 연구 내용에 따라서 운동기술분석 44.5%, 측정 및 자료처리 38.4%, 상해관련 12.3%, 기타 10%로 나타났다. 연구 방법에 따라서는영상분석 60.7%, 근전도 10.9%, 압력판 9%로 나타났으며, 영상분석과 압력판을 이용한 연구(6.2%)와 영상분석과근전도를 이용한 분석(2%), 그리고 기타의 방법(15.2%) 등을 이용한 것으로 나타났다. 최근 5년(2009~2014)간 초등체육과 관련한 운동역학 연구는 한국체육학회지 0.1%, 한국운동역학회지 1.3%, 한국초등체육학회지 4.5%로 나타났다. 연구내용은 운동기술분석(66.7%), 측정 및 자료처리와 상해관련(각각 16.7%)의 연구였으며, 연구방법으로는 영상분석 관련 연구가 대부분(83.3%)을 차지하였다. 이처럼 운동역학 관련, 특히 초등체육에서의 연구가 미진한 이유는 연구여건의 미비, 전문 연구인력의 부족, 기초자료 부족, 그리고 연구대상자 확보와 통제의 어려움이주요 원인으로 판단된다. 따라서 전문연구 인력 및 실험실과 연구기자재의 확보, 흥미를 유발할 수 있는 편안한강의, 현장성 있는 연구와 함께 체계적인 분석 및 지도방법의 모색 등을 통해서 활성화 할 수 있도록 노력해야할 것이다. The purpose of this study was to identify current trend and issues and to activating sport biomechanics research related to general sport science and elementary physical education. In order to achieve purpose of the study, research published in The Korean Journal of Physical Education(KJPE), Korean Journal of Sport Biomechanics(KJSB), and The Korean Journal of Elementary Physical Education(KJEPE) were analysed. Based on analysis of biomechanics research in past 3 years, motor skill analysis(44.5%) was the most frequently appeared in the studies followed by measurement and data processing(38.4%), injury(12.3%), and others(10%) respectively in terms of content of the research. Research methods used in the studies were image analysis(60.7%), electromyogram(10.9%), and pressure plate(9%). There were also studies used both image analysis and pressure plate(6.2%), image analysis and electromyogram(2%) and others(15.2%). Based on analysis of biomechanics research in past 5 years related to elementary physical education, it was shown in KJPE(0.1%), KJSB(6.2%), and KJEPE(4.5%). Research contents were motor skill analysis(66.7%), measurement and data processing, and injury(16.7%) respectively and most of research(83.3%) were used image analysis as research method. Reasons of the lack of research related to biomechanics, especially elementary physical education would be insufficiency of the research conditions, lack of professional researchers, lack of basic data, and difficulty of having and controling samples. Therefore, it should be make efforts to secure professional researchers, lab, and equipments, to make effective teaching created more interests about biomechanics, and to conduct research having more practically oriented along with systematic analysis and teaching method.

The volleyball is characterized as the game where the players pursue the victory by succeeding the attack typically composed of the three-steps, i.e., service receive, set, and spike. Therefore, the winning possibility would be increased when the aforementioned three techniques are performed successfully. This study was designed to the influence of service receive success rate and spike success rate on team standing and to the relationship between the receive success rate and the spike success rate. To achieve the purposes, the official records of all games(102 games) of Korean Volleyball Super League, provided by the Korean Volleyball Association, were analyzed. Data were analyzed utilizing the SPSS Window 7.5 version. The descriptive statistics and correlation analysis with Pearson's r value were performed. There were positive relationship between the service receive success rate and the team standing as well as between the spike success rate and the team standing(p〈.01). In addition, there was a positive relationship between service receive success rate and the spike success rate(p〈.01). Approximately 57% and 77% of the team standing was found to be explained by service receive success rate and spike success rate, respectively. It was evident that the service receive success rate and the spike success rate should be high to improve the team standing. Additionally, a great deal of the time should be assigned to the practice of the service receive. However, the team standing couldn't be fully explained by the receive and spike. The future studies on the other techniques, e.g., setting, would be warranted.
